Its role in decay is replaced by the pin/edge/mention + signals the decay flagger already has (see §7). +- **`mention` is a DOUBLE, not INT.** Passive RAG bumps it by a configurable + fractional amount (default 0.1); `search_memory` bumps by 1.0. +- **`created_at`/`updated_at`/`mention` are agent-read-only.** They are returned + in tool output but there is no tool parameter to set them. Tools set them as a + side effect. +- **Schema version lives in `GraphMeta`.** A single `schema_version` key drives + future forward migrations. We keep the idempotent-migration pattern from the + old code but start clean at v2 (the old incremental `migration_*_v1` flags do + not carry over; `migrate.py` in §11 handles the one-time old→new move). + +`scope` and `pinned` both use the same **scope grammar** (§4) so one parser +serves both. This is intentional: a pin *is* a scope-shaped statement of "always +surface here." + +--- + +## 2. Concurrency & consistency (was unaddressed) + +LadybugDB is single-writer. Every write in the system funnels through **one +process-wide `asyncio.Lock` (`write_lock`)** held by the `GraphDatabase` +singleton and shared to every writer (main-agent tools, Extractors, Reviewers, +Deduper). Reads use short-lived read connections and do not take the lock. + +- **Unique-name-in-scope is enforced atomically.** `memory_add_entity` performs + the existence check and the `CREATE` *inside the same `write_lock` acquisition*. + Two Extractors racing to add the same `(name, scope)` cannot both win: the + second sees the first's node and is rejected. This closes the TOCTOU race the + old code technically had (its check and create were both under the lock but + the logic is now specified as a single critical section, not two calls). +- **Description-diff apply is lock-guarded and re-validated.** `memory_update_ + entity_description` reads the current description, applies the diff, and writes + back all under one lock hold. If the base text the diff was generated against + no longer matches (concurrent edit), the diff will not apply cleanly → return + a distinct "stale base, re-read and retry" error (separate from "malformed + diff"; see §6). +- **Reviewer queue durability.** The issue queue is **not** purely in-memory. It + is persisted to `data/reviewer_queue.json` (in the agent-unreadable `data/` + dir, §10) and rehydrated on startup, so `memory_stats`' backlog counts survive + a restart and unprocessed issues are not lost. In-memory is the working copy; + the file is written on enqueue/dequeue (debounced). + +--- + +## 3. Vector index (concrete answers) + +- **Hash input:** `embed_hash = sha256(embed_content)` where `embed_content` is + the rendered string `"{name} ({entity_type})\n{description}"`. Name, type, and + description all contribute; scope/pin/mention do **not** (they don't change + semantics). Changing any hashed field zeroes `embed_hash`, marking the row for + re-embed on the next embedding pass. +- **Model & dimension:** one configured embedding model (`embedding_model` in + config). Dimension is model-dependent, so we keep the variable-length + `DOUBLE[]` column and compute cosine in Python (numpy fast path, pure-Python + fallback) — same rationale as the old code. Dropping the second model removes + all `graph_*` columns. +- **Cache location & efficiency:** the vector index is an **in-memory matrix + cache** (`{uuid: np.ndarray}` plus a stacked matrix for batched cosine) held by + the `GraphDatabase` singleton, rebuilt lazily. Invalidation is driven by a + cheap dirty-set: any write that zeroes an `embed_hash` (or deletes an entity) + adds/removes that uuid from the cache. We never re-scan the whole table to + detect staleness — the hash mismatch *is* the signal, and the writer that + causes it registers the dirty uuid. A background embedding pass drains the + dirty set, computes embeddings, writes `embedding` + `embed_hash`, and updates + the matrix. Cache survives within a process; on cold start it is rebuilt from + rows whose `embed_hash` is non-empty (no recompute needed for already-embedded + rows). +- **Migration interaction:** `migrate.py` (§11) copies old `embedding` + + `embed_hash` verbatim when the old and new embed_content rendering match; + otherwise it zeroes `embed_hash` so the row re-embeds lazily. It never blocks + migration on embedding calls. + +--- + +## 4. Scoping (new — the largest genuinely-new subsystem) + +Scope is an **information-isolation** mechanism, not an ownership tag. Format: +`scope_name:target`, or the bare literal `global`. Examples: `global`, +`user:itzpingcat`, `guild:1234`. + +**Critical rule restated:** scope ≠ ownership. Most `Person` nodes are +`global`. Scope only restricts *where sensitive/personal info is visible*. A +node about user Able that is not sensitive should usually be `global` so it is +useful everywhere. + +### 4.1 `scopes.py` — resolved once per AgentCycle + +A dedicated `scopes.py` computes the **visible scope set** for the current +cycle from environment state: + +``` +resolve_scopes(env) -> set[str] + # Always includes "global". + # Adds "guild:" if the conversation is in a guild. + # Adds "user:" for every human who spoke in the last N messages. +``` + +For the review example (Able + Bill in guild 1234): visible set = +`{global, guild:1234, user:able, user:bill}`. `user:carl` is **not** in the set, +so Carl's scoped nodes are invisible. This set is the single authority for +visibility. + +### 4.2 Enforcement is at the tool/query layer, not just injection + +This is the key regression fix: the old system filtered visibility only at +prompt-injection time; `kg_search`/`kg_traverse` saw the whole graph. In v2, +**every read path takes the visible-scope set and filters at the query.** +`search_memory`, passive RAG, `memory_stats`, and traversal all restrict to +`WHERE e.scope IN $visible`. There is no code path that returns a node outside +the caller's visible set. + +### 4.3 Scope on writes (who decides global vs user:x) + +- `memory_add_entity` takes an explicit `scope` param. **Default is `global`.** +- Extractors are the main writers. Their system prompt gives an explicit + decision rule: *default to `global`; use `user:` or `guild:` ONLY + for information that is personal, sensitive, private, or clearly meaningful + only within that bucket.* This judgment is the Extractor's, but it is bounded: + an Extractor may only write to scopes within the scope set it was handed by + `scopes.py` (it cannot write `user:carl` if Carl isn't in the resolved set). + A "too much personal data landed in `global`" case becomes a **flagger** + (§9) rather than being relied on to never happen. + +### 4.4 Scope on relationships + +Edges are **not** independently scoped. An edge is visible iff **both endpoints +are visible** in the current scope set. So a `global` node A linked to +`user:able` node B: the edge is visible to Able (both endpoints visible) and +invisible to Bill (B not visible). This avoids a second scope grammar on edges +and makes visibility composable and predictable. Traversal never crosses into an +invisible node, so no edge can leak the existence of an out-of-scope entity. + +--- + +## 5. Passive RAG & pinning + +Implemented as a `PromptProvider` that emits a single `` block, refreshed +each turn via `post_turn_hook` (carrying forward the old cache/executor pattern). + +### 5.1 Retrieval + +Take the **last user message**, run hybrid retrieval over the visible-scope set: +BM25 + vector, fused with RRF. + +- **min-p is applied *before* RRF** (explicit requirement). Each retriever drops + candidates below its configured minimum similarity/score first; only survivors + are ranked and fused. This prevents a globally-irrelevant node from riding a + high reciprocal rank into the block just because the candidate pool was small. +- RAG can be **disabled** (config `passive_rag_enabled`), leaving only pinned + entities in the block. + +### 5.2 Pinning + +`pinned` uses the scope grammar. Semantics: a pinned entity **bypasses the RAG +similarity search and is always present** in the `` block whenever its +pin target is in the current visible-scope set. `pinned == ""` means unpinned. +Option `pin_include_neighbors` (config): when on, also pull entities directly +linked to pinned entities into the block. + +### 5.3 Deduplication of the block (specified, not just intended) + +The block is assembled from up to three overlapping sources (BM25 hit, vector +hit, pinned, optionally pin-neighbors). Assembly: + +1. Collect candidates from all sources into a `dict` keyed by **uuid** (set + semantics — an entity present in three sources appears once). Record its + provenance (pinned vs. rag) for ordering. +2. Order: **pinned first**, then RAG hits by fused score, then pin-neighbors. +3. Apply the token cap (`memory_block_tokens`) walking the ordered list. + +### 5.4 Token-cap / over-budget behavior (was ambiguous) + +- If **pinned entities alone exceed** the budget: pins are included in pin + insertion order (a stable order — e.g. most-recently-updated first) until the + budget is hit; the overflow is dropped and a single truncation marker line is + emitted (`… N pinned entities omitted (token budget)`). Over-pinning at a + scope is itself a flagger (§9), so this state is surfaced for cleanup rather + than silently tolerated. +- RAG hits are only added after pins; if no room remains, none are added. + +### 5.5 Mention accounting + +- Passive retrieval of a **non-pinned** entity bumps `mention` by + `passive_mention_bump` (default 0.1). Pinned entities are **not** bumped by + passive injection (they're always there; bumping would be meaningless). +- `search_memory` bumps `mention` by 1.0. +- **Decay of mention:** because the destructive decay sweep is gone, `mention` + would otherwise be a monotonic counter. To keep it meaningful for the + "orphaned / junk" and "too little used" flaggers, a lightweight **recency + half-life is applied at read time** when computing a node's effective + mention-weight for flaggers (the stored value stays monotonic for audit; the + flagger uses `mention * 0.5^(age_days / half_life)`). No data is deleted by + this — it only affects flagger ranking. + +--- + +## 6. Tools + +All graph-editing tools live in **one `tools.py`** with shared helpers +(`_resolve(name_or_uuid)`, `_visible_scope_guard`, `_set_meta_timestamps`, +scope-grammar validate, relation validate). + +**Main TinyCTX agent** gets only: `search_memory`, `memory_stats`, +`call_librarian`. +**Librarian subagents** get all tools below. + +Relation validation: every relation string is uppercased and must match +`^[A-Z][A-Z0-9_]*$` (SCREAMING_SNAKE_CASE) or the call is rejected with a +corrective message. There is a default vocabulary (§8) that is *encouraged, not +enforced* — novel valid-format relations are allowed. + +### `search_memory(query, top_k, min_p=cfg)` +Primary read path. **Exact match short-circuit:** if `query` exactly matches a +visible entity name or UUID, return that entity immediately (respecting +`min_p` only for the fuzzy path). Otherwise BM25 + vector with **min-p applied +before RRF**. Bumps `mention` by 1.0 on every returned node. Scope-filtered to +the caller's visible set. + +### `memory_add_entity(name, entity_type, description, scope="global")` +Rejects if `(name)` already exists **in the same scope** (atomic, §2). Sets +`created_at`/`updated_at`. Zeroes `embed_hash` → registers dirty uuid. +- **On collision, return the existing entity's full data** (uuid, type, scope, + pin, description, and its edges) in the rejection message — carry forward the + old behavior — so the agent can decide whether to update/merge without a + redundant `search_memory` round-trip. + +### `memory_update_entity_description(name_or_uuid, description_diff)` +Applies a unified-diff to the existing description under the write lock. Bumps +`mention` by 1.0 on the target, sets `updated_at`, zeroes `embed_hash`. +- **Malformed diff** → warn, ask the agent to retry. +- **Clean-but-stale base** (concurrent edit moved the text) → distinct + "description changed underneath you, re-read and regenerate the diff" error. + +### `memory_set_entity_pinned(name_or_uuid, pinned)` +Validates `pinned` against scope grammar (or `""`). Sets `updated_at`. + +### `memory_set_entity_scope(name_or_uuid, scope)` +Validates scope grammar. Sets `updated_at`. + +### `memory_delete_entity(name_or_uuid)` +Hard-delete node + all edges (`DETACH DELETE`). Removes uuid from vector cache. + +### `memory_set_relationship(from, to, relationship_type, weight)` +Adds an edge. **Conflict resolution:** relationship groups are declared with +`/` in the default list (§8) and are treated as **symmetric mutually-exclusive +sets** *between the same ordered pair*. Adding `SUPERSEDES` between A→B deletes +any existing `DEPENDS_ON` or `CONFLICTS_WITH` between A→B. If the *same* +relation already exists between the pair, **update its weight** instead of +duplicating. Scope of the edge is implicit (§4.4); both endpoints must be +visible to the caller. + +### `memory_delete_relationship(from, to, relationship_type)` +Deletes the given relation type between the ordered pair. `relationship_type == +""` deletes **all** relations between the pair. Directional: `from→to` only; the +reverse edge (`to→from`) is left untouched unless separately targeted. + +### `memory_merge_into(canonical, duplicate, merged_description, verdict="duplicate")` +Librarian-only. Collapse `duplicate` into `canonical`: +- `verdict="duplicate"`: re-point all of the duplicate's in/out edges to + `canonical` (skipping self-edges and collapsing onto existing relations of the + same type via the weight-update rule), set `canonical.description = + merged_description`, zero `canonical.embed_hash`, then `DETACH DELETE` the + duplicate and drop its vector-cache entry. +- `verdict="alias"`: keep both, add `duplicate -[ALIASED_TO]-> canonical` + (weight 1.0), rewrite the duplicate's description to a redirect stub, update + the canonical description. +- Accepts UUID or exact name for both args; errors if either is unresolved, if + they resolve to the same node, or if the two are not both visible in the + caller's scope. Sets `updated_at` on the survivor(s). This is the explicit + merge entry point (the Deduper pipeline in §10 calls the same internal helper). + +### `memory_stats()` +Entity counts by type, relationship count, pinned counts by scope, embedding +coverage, top-mentioned — **all scope-filtered to the caller**. Also returns the +Reviewer backlog: count of pending issues **by flagger type** (read from the +persisted queue, §2). + +### Removed old tools — disposition (no silent regression) +- `kg_traverse` → folded into `search_memory` result (each hit shows its direct + edges) and available to librarians via a helper; a thin `memory_traverse` is + retained **for librarians only** if Reviewers need multi-hop walks. +- `kg_get_entity` / `kg_list` → covered by `search_memory` exact-match + stats. +- `kg_merge_entities` → **replaced** by `memory_merge_into` (librarian-only, + above) and the Deduper pipeline (§10), which share one internal merge helper. + Not exposed to the main agent. +- **No rename / retype tool** exists in the old system either; v2 keeps it that + way. Renaming = add new + merge, retyping likewise. If direct rename/retype is + wanted, it's a small addition — flagged, not assumed. + +--- + +## 7. Decay becomes a flagger (not a deleter) + +The old sweep min-max-normalized five factors **relative to the current +candidate set every run** and hard-`DETACH DELETE`d anything below threshold — +which is exactly how legitimately-important-but-quiet nodes got destroyed. v2 +kills the auto-deleter entirely. + +Decay is reborn as a **Reviewer flagger** (§9) that identifies *candidates for +review* — low effective-mention (§5.5), few edges, far from any pinned node, +stale `updated_at` — and enqueues them as "stale, assess" issues. The Reviewer +LLM then decides: link it up, leave it, or delete it. **Nothing is deleted +without a judgment step.** Thresholds are absolute and configurable, not +relative to the sweep's population, so a quiet-but-important node is never +mechanically doomed. + +--- + +## 8.

Only the default +groups carry `/` conflict semantics; custom relations are standalone. + +--- + +## 9. Librarian subagents + +Background agents that maintain the graph. All share the full toolset. Each type +has a script that resolves **exactly** the scope it needs and nothing more. + +### 9.1 Extractors +Pull unvisited branches from `agent.db` (carry forward the `flag_branch(..., +"librarian_visited")` mechanism) and ingest their information. Scope resolution = +environment state + the humans who spoke in the last N messages (via +`scopes.py`). Context is built with `sanitize_brackets` (carry forward the +existing injection defense) and the "never extract from the assistant's own +turns" rule. Extractors default new nodes to `global` and only narrow scope for +sensitive info (§4.3). + +### 9.2 Reviewers + Flaggers +**Flaggers** are short graph-scanning snippets in `/flaggers`, dynamically +loaded at runtime. Each flagger: +- scans the graph (or a scope) and yields issues, +- builds its own prompt fragment appended to a shared Reviewer base prompt, +- declares the scope the Reviewer should operate in. + +The **Reviewer orchestrator** loads all flaggers, runs them, and appends new +issues to the persisted queue (§2). Concrete mechanics: + +- **Issue identity / dedup key:** `(flagger_type, sorted(entity_uuids))`. An + issue already in the queue (by this key) is never appended twice. +- **Dedup vs. processing interlock:** the queue is **not** processed while a + dedup/append pass is running (a simple `asyncio.Event` gate). This prevents + processing a half-deduplicated queue. +- **Throttle (concrete):** inter-issue delay scales with backlog so we're not + bursty. `delay = clamp(base_delay * (target_len / max(len,1)), min_delay, + base_delay)` — i.e. long queue → shorter waits (drain faster), short queue → + spaced out. All three constants are config (`reviewer_base_delay`, + `reviewer_min_delay`, `reviewer_target_len`). No magic numbers. + +Example flaggers (each self-contained in `/flaggers`): +- **Too many edges between the same pair** (even if different relations). +- **Description too long** → split into specialized entities. +- **Description too short** → assess whether it's junk. +- **Orphaned entity** → link up or destroy. +- **Too many pins at scope X** → propose unpins. +- **Decay candidate** (§7) → stale/quiet/isolated node, assess. +- **Near-duplicate names** via `rapidfuzz` (§9.4). + +### 9.3 `call_librarian` (main agent) +Enqueues a flagged issue at the **front** of the Reviewer queue (priority jump). +Same dedup key applies. + +### 9.4 Fuzzy-name flagger vs. embedding Deduper (relationship clarified) +These are **complementary, independent** duplicate detectors: +- **Fuzzy-name flagger** (`rapidfuzz`, threshold `fuzzy_name_threshold`, default + ~90) catches lexical near-duplicates that *embeddings miss or mis-score*. It + **ignores pairs already linked by `IS_NOT`**. If the Reviewer decides two + fuzzy-matched nodes are genuinely distinct, it writes an `IS_NOT` edge so the + pair is never re-flagged. It runs on a schedule over the graph (not every + cycle — `fuzzy_scan_interval_hours`) and **may compare across different + scopes**, leaving the merge/keep decision (and any scope reconciliation) to the + Reviewer. +- **Embedding Deduper** (§10) catches *semantic* duplicates with different + surface names. Different signal, different pipeline. Neither supersedes the + other; overlap (a pair caught by both) is harmless because the queue dedup key + and the dedup cache both prevent double-work. + +--- + +## 10. Deduplication pipeline + +Runs on a schedule. Steps: +1. **Embedding pass** generates candidate pairs (cosine ≥ `similarity_threshold`) + over the up-to-date vector cache. +2. **Greedy Clique-Edge-Cover** groups candidates into batches + (`dedup_batch_count`) so each LLM call verifies a coherent cluster (carry + forward the old `_clique_edge_cover`). +3. LLM verifies duplicates per batch; confirmed dups are merged. +4. **Dedup cache** records already-compared pairs so we don't re-spend on them. + Location: a sidecar under `data/` (carry forward the old separate-SQLite + pattern — `data/dedup_cache.db`, table `distinct_pairs`) so it stays in the + agent-unreadable dir and doesn't bloat `memory.lbug`. + +Merge itself re-points edges from duplicate to canonical, consolidates the +description, deletes the duplicate, and invalidates both vector-cache entries. + +--- + +## 11.

The old `priority` field, the second `graph_*` embedding model, and the `superseded_at` soft-delete column are all removed. `mention` is a DOUBLE (passive RAG bumps +0.1, `search_memory` +1.0) and, with `created_at`/`updated_at`, is agent-read-only. `GraphMeta.schema_version = "2"`. + +**Scoping** (`scopes.py`) is information isolation, not ownership — most nodes are `global`. Grammar `global` | `kind:target` (`user:bob`, `guild:my_server`), reused by the `pinned` field. `resolve_scopes(env, active_users)` computes the per-cycle visible set (global + guild + recent participants); enforcement is at the **query layer** — every read filters `WHERE e.scope IN visible` and an edge is visible only if both endpoints are. The scope set is carried per-task in a `contextvars.ContextVar` (`tools.scope_context`), so concurrent librarians with different scopes don't collide. + +**Vector index** (`graph.py VectorIndex`) is an in-memory matrix cache invalidated by a dirty set the writers populate (embed_hash zeroed → removed from index; the embedding pass re-adds). `search()` applies **min-p before top-k** and restricts to an `allowed` uuid set. Cosine via numpy with a pure-Python fallback. + +**Tools** (`tools.py`, single file). Main agent: `search_memory` (exact-match short-circuit, else hybrid BM25+vector with **min-p before RRF**), `memory_stats` (scope-filtered + reviewer backlog), `call_librarian`. Librarians additionally get `memory_add_entity` (atomic unique-name-in-scope; returns existing node data on collision), `memory_update_entity_description` (unified-diff apply; distinguishes malformed vs stale-base), `memory_set_entity_pinned`, `memory_set_entity_scope`, `memory_delete_entity`, `memory_set_relationship` (SCREAMING_SNAKE_CASE validated; `/`-groups in `prompts/default_relations.txt` are mutually-exclusive within an ordered pair), `memory_delete_relationship`, `memory_merge_into` (duplicate/alias; shares an internal helper with the deduper). + +**Librarians.** `extractor.py` ingests unvisited conversation branches within a resolved write scope (defaults new nodes to `global`, narrows only for sensitive info). `reviewer.py` loads dynamically-registered flaggers from `flaggers/` (orphaned, description_length, too_many_edges, over_pinned, decay_candidate, fuzzy_names), maintaining a **persisted** de-duplicated issue queue (`data/reviewer_queue.json`, key `(flagger_type, sorted(uuids))`, survives restart) drained with an adaptive throttle. `deduper.py` runs the embedding pass plus semantic dedup (candidate pairs → greedy clique-edge-cover → LLM verify → merge; distinct pairs cached in `data/dedup_cache.db`). Shared agent-loop/tool-handler/sanitized `nodes_to_text` plumbing is in `librarian_common.py`. The `【author】: content` rendering + `sanitize_brackets` injection defense and the "never extract from the assistant's own turns" rule are preserved. + +**Decay** is no longer an auto-deleter: the `decay_candidate` flagger surfaces stale/quiet/isolated nodes for the Reviewer to *assess* (absolute thresholds, never population-relative), so quiet-but-important data is never mechanically destroyed. + +**Migration** (`migrate.py`): one-shot, runs when `graph.lbug` exists and `memory.lbug` doesn't; maps v1→v2 (everything → `global` scope, `pinned_target`→`pinned`, `mention_count`→`mention`, drops `priority`/`graph_*`, skips superseded edges, preserves embeddings only when the hash matches else lazy re-embed), verifies counts, then **renames** the old file to `.migrated.bak` (never deletes; `--purge` removes the backup, `--dry-run` writes nothing). + +Superseded modules `decay.py` / `dedup_agents.py` / `librarian_agents.py` are inert deprecation stubs (file deletion was unavailable in the authoring environment). Tests: `tests/test_memory.py` (16 pure-logic + fake-backed scope-isolation tests; live-DB paths need a ladybug + py3.14 environment). ### `heartbeat` — fires periodic agent turns on a background DB branch at a configured interval. Suppresses `NO_REPLY` replies (same sentinel as `agent.py`'s `NO_REPLY_TOKEN` — unified single marker, was `HEARTBEAT_OK`). Slash command: `/heartbeat run`. diff --git a/TinyCTX/modules/memory/__init__.py b/TinyCTX/modules/memory/__init__.py index 0baf263..1cbc990 100644 --- a/TinyCTX/modules/memory/__init__.py +++ b/TinyCTX/modules/memory/__init__.py @@ -1,81 +1,65 @@ -EXTENSION_META = { +EXTENSION_META = { "name": "memory", - "version": "0.2", + "version": "2.0", "description": ( - "Long-term memory backed by a LadybugDB property graph.

memory_add_entity always creates at scope "global" — there is no scope argument on it.

This is the exception, not the default. - The person the conversation is about is NOT automatically "sensitive".

The Person node stays global. - Being in the writable_scopes list for this cycle is not a reason to narrow scope — it only tells you what you're ALLOWED to write, not what you SHOULD write.

Callers that cannot tolerate a partial result (e.g. `modules/rag/indexer.py`'s `_index_file()`, which must not mark a file "indexed" when a chunk's embedding actually failed) must check the returned list for `None` themselves and raise/abort — `embed()` itself no longer does that for them. ### Priority queue diff --git a/TinyCTX/ai.py b/TinyCTX/ai.py index 09af740..0a7eb90 100644 --- a/TinyCTX/ai.py +++ b/TinyCTX/ai.py @@ -527,6 +527,13 @@ async def embed(self, texts: list[str], priority: int = 10, kind: str = "default tmpl = "{text}" texts = [tmpl.format(text=t) for t in texts] + async def _embed_one_item(item: str) -> "list[float] | None": + try: + return (await self._call([item]))[0] + except Exception as item_exc: + logger.warning("Embedding item failed, leaving it as None: %s", item_exc) + return None + async def _run(): results: list[list[float] | None] = [] for i in range(0, len(texts), self.batch_size): @@ -538,12 +545,11 @@ async def _run(): "Embedding batch of %d failed (%s); retrying items individually", len(batch), exc, ) - for item in batch: - try: - results.extend(await self._call([item])) - except Exception as item_exc: - logger.warning("Embedding item failed, leaving it as None: %s", item_exc) - results.append(None) + # Concurrent, not sequential: these are independent single-item + # calls, and a worker holds its slot until _run() returns, so + # retrying batch_size items one at a time here would tie up the + # slot for up to batch_size extra sequential round trips. + results.extend(await asyncio.gather(*(_embed_one_item(t) for t in batch))) return results return await _enqueue(priority, _run) From c86a9b310da5dbeefadc63e201ced9f4dd244652 Mon Sep 17 00:00:00 2001 From: ItzPingCat Date: Sat, 25 Jul 2026 13:48:47 -0700 Subject: [PATCH 30/46] feat: cli bridge improvements --- TinyCTX/bridges/cli/__main__.py | 33 +++++++++++++++------ TinyCTX/commands/launch.py | 39 ++++++++++++++++++++----- TinyCTX/gateway/__main__.py | 37 ++++++++++++++++++++++++ TinyCTX/users/store.py | 51 +++++++++++++++++++++++++++++++++ 4 files changed, 144 insertions(+), 16 deletions(-) diff --git a/TinyCTX/bridges/cli/__main__.py b/TinyCTX/bridges/cli/__main__.py index 3776af2..ea8f4e4 100644 --- a/TinyCTX/bridges/cli/__main__.py +++ b/TinyCTX/bridges/cli/__main__.py @@ -564,7 +564,7 @@ async def _handle_help(self) -> None: # Built-in commands always available locally. builtin_rows = [ ("/reset", "Start a new session branch"), - ("/resume", "Reattach to the session from before this launch"), + ("/resume [node_id]", "Reattach to the session from before this launch, or to node_id"), ("/copy", "Copy last agent reply to clipboard"), ("/paste", "Submit clipboard contents as next message"), ("/think", "Toggle display of thinking content (currently " + @@ -658,22 +658,37 @@ async def run(self) -> None: continue # -------------------------------------------------------- - # Built-in: /resume — reattach to the session that was - # active before this launch started a fresh branch. + # Built-in: /resume [node_id] — reattach to the session + # that was active before this launch started a fresh + # branch, or to an explicit node_id if one is given. # -------------------------------------------------------- - if lower == "/resume": - if not self._resume_cursor: + if lower == "/resume" or lower.startswith("/resume "): + arg = text[len("/resume"):].strip() # preserve case + target_node = arg or self._resume_cursor + if not target_node: self._console.print( f"[{c('reset')}] · no previous session to resume" f"[/{c('reset')}]") continue - await self._api_post( - "/v1/lane/open", {"node_id": self._resume_cursor}) - self._cursor = self._resume_cursor + data = await self._api_post( + "/v1/lane/open", {"node_id": target_node}) + opened_node = data.get("node_id") + # /v1/lane/open silently starts a fresh branch when + # node_id is unknown instead of erroring — a mismatch + # between what we asked for and what came back is how + # we detect that and report it instead of quietly + # resuming the wrong (new) session. + if arg and opened_node != target_node: + self._console.print( + f"[{c('error')}] ✗ session '{target_node}' not found" + f"[/{c('error')}]") + continue + self._cursor = opened_node if self._instance_dir: _save_cli_cursor_path(self._instance_dir, self._cursor) + label = f"resumed session {opened_node}" if arg else "resumed previous session" self._console.print( - f"[{c('reset')}] ⟲ resumed previous session" + f"[{c('reset')}] ⟲ {label}" f"[/{c('reset')}]") continue diff --git a/TinyCTX/commands/launch.py b/TinyCTX/commands/launch.py index f8141c2..647eb20 100644 --- a/TinyCTX/commands/launch.py +++ b/TinyCTX/commands/launch.py @@ -13,10 +13,11 @@ ----- --dir PATH Path to a .tinyctx instance directory. --config PATH Path to config.yaml directly (overrides --dir/autodetect). - --user USERNAME TinyCTX username to log in as.

Legacy SillyTavern lorebook/worldinfo JSON dropped at the root of a databank dir is auto-converted the first time it's discovered — `discover_databanks()` writes one native lore `.md` doc per active entry into a same-named folder (`lorefile.convert_lorebook_json`), then renames the original to `.json.bak` (never deletes) so it's never re-converted; from then on it's an ordinary folder databank, no JSON support at runtime. `FilesDataBank` (`modules/rag/databanks.py`) is the only databank kind — `LoreBookDataBank` no longer exists, and there's no separate `DataBank` protocol either; callers type against `FilesDataBank` directly. + +**Auto-inject is both keyword-triggered and semantic, gated per-entry by `mode`.** `FilesDataBank.auto_inject(text, store=None, embedder=None, top_k=0, bm25_weight=0.3)` is `async`: it runs ST-style keyword/regex matching (ported selectiveLogic AND_ANY/NOT_ALL/NOT_ANY/AND_ALL) over frontmatter entries deterministically, and when a `store` is passed it additionally runs the same hybrid BM25+vector search `rag_search` uses over the whole databank index, merging in new hits deduplicated by resolved file path. Each entry's frontmatter `mode` (`lorefile.LoreEntry.mode`, default `"hybrid"`) decides which half applies to it: + - `hybrid` (default) — deterministic firing AND eligible for the passive semantic merge. + - `vector` — semantic-only; skips keyword/regex matching entirely regardless of `keys`/`constant`. + - `keyword` — deterministic-only via literal substring/whole-word `keys`; excluded from the semantic merge so it never surfaces passively without a keyword hit. + - `regex` — like `keyword`, but `keys` (and `secondary_keys`) are compiled as regular expressions (`lorefile.compile_regex_key` — accepts SillyTavern's `/pattern/flags` syntax, or a bare pattern) instead of literal substrings; also excluded from the semantic merge. + + `rag_search` (the explicit tool) is unaffected by `mode` — it always searches the full hybrid index regardless. Legacy lorebook conversion (`convert_lorebook_json`) auto-assigns `mode: regex` when any of an entry's keys use ST's `/pattern/flags` syntax, else `mode: keyword` (converted entries never default to `hybrid`/`vector` since legacy lorebooks have no concept of embeddings — edit the converted `.md` by hand to opt in). The pre-assemble hook in `modules/rag/__main__.py` syncs each auto-rag target's indexer before calling `auto_inject`, same as `rag_search` does. + +**`FilesDataBank` caches parsed entries by `(path, mtime)`** (`_entry_cache` in `databanks.py`) so `iter_files()`/`auto_inject()` — the latter invoked once per user turn per auto-rag target — don't re-read and re-parse every file in the folder when nothing on disk changed; stale cache entries are dropped when a file disappears or falls outside the indexed extensions. + +**Auto-rag targets have a configurable default.** `default_auto_targets` (list of databank names, default `[]`) in `EXTENSION_META`'s `default_config` is used by the pre-assemble hook when a branch's `rag_auto_targets` session-state key was never written (`get_state` returns `None`) — once `set_auto_rag_databanks` is called on a branch, even with `[]` to explicitly clear it, that stored value wins over the config default from then on. + +**Module state in `modules/rag/__main__.py`** is one `_RagState` dataclass instance (`_state`) instead of eight separate module globals (`initialized`, `stores`, `indexers`, `databanks`, `embedder`, `cfg`, `workspace`, `strategy`, `model_name`). ### `memory` (v2) — scoped LadybugDB property-graph knowledge store at `/data/memory/memory.lbug` (not workspace/).

Callers below `neutral` may only run whitelisted commands; callers below `bypass_blacklist` are still blacklist-checked; `backend_access=True` requires `access_backend`. The tool is registered with `min_permission=use_whitelist` (not a fixed 45), so whitelist-tier callers can now see/call it at all — enforcement of what they can actually run happens inside `_dispatch()`. ### `web` — `web_search` (DuckDuckGo via `ddgs`) and `open_url` (Playwright, headless by default; `headless=False` for captchas). diff --git a/TinyCTX/modules/shell/__init__.py b/TinyCTX/modules/shell/__init__.py index 9d41efd..d4b0813 100644 --- a/TinyCTX/modules/shell/__init__.py +++ b/TinyCTX/modules/shell/__init__.py @@ -1,12 +1,13 @@ EXTENSION_META = { "name": "shell", - "version": "1.2", + "version": "1.3", "description": ( "Shell execution tool.

Rules move to two structured YAML +files that can express subcommands, flags, and argument shapes — not just +"does this string contain `rm -rf`". + +Status: **approved, in implementation.** All open questions resolved — see §11. + +--- + +## 0. Why + +The current matcher operates on the raw command string: + +- `_check_blacklist` does `pattern.search(command.lower())` — a **substring** match. + So `echo "i"; echo "am"; echo "harmless"` is blocked by any pattern that happens + to appear anywhere in it, and `git commit -m "don't rm -rf your repo"` is blocked + by `rm -rf*`. Both are false positives on *quoted data*, which the matcher + cannot distinguish from *code*. +- `_check_whitelist` does `pattern.fullmatch(...)` on the whole string. Anchoring is + the right instinct — it stops `git status; rm -rf /` from riding a `git status` + entry — but it means the whitelist can only express whole fixed command lines. + `git log` and `git log --oneline` need two entries. There is no way to say + "git, subcommand log, any of these flags". +- The `{arg}` placeholder exists purely to work around the lack of parsing: it + expands to a character class that excludes every shell metacharacter, so a + caller-supplied string can't break out of `echo "..."`. It is a hand-rolled + lexer, and it costs the caller apostrophes, quotes, `$`, and newlines. + +Every one of these is a symptom of matching text instead of structure. + +Parsing fixes the class of problem, not the instances: + +``` +echo "i"; echo "am"; echo "harmless" + → program + command(echo, string:"i") + command(echo, string:"am") + command(echo, string:"harmless") +``` + +Three independent `command` nodes, each validated on its own. And: + +``` +git commit -m "msg with ; and | chars" + → command(git, word:commit, word:-m, string:"msg with ; and | chars") +``` + +The `;` and `|` arrive as `string_content` — a **leaf**, unambiguously data. No +character-class hack needed, because the parser already decided. + +Verified against `tree-sitter-bash` (see §9 for the parse dumps this plan is +built on). + +--- + +## 1. Decisions taken + +1. **Windows/PowerShell support is removed.** After the container refactor the + shell always runs on Linux — sandbox container by default, main TinyCTX + container for `backend_access=True`. `_IS_WINDOWS`, `_normalize_windows()`, + the PowerShell `subprocess.run` branch, `CREATE_NO_WINDOW`, and the Windows + keys in `_SAFE_KEYS` all go. This also deletes ~60% of `blacklist.txt` + (the entire PowerShell section), which was never reachable in the deployed + configuration anyway. +2. **The `neutral` tier keeps its current posture: allow-by-default, deny-list.** + Anything runs unless a rule denies it. The change is *what* the deny rules + match on, not the posture. +3. **The sub-`neutral` tier gets the nuanced allow-list.** Deny-by-default, + with per-command subcommand/flag/argument constraints. +4. **Two YAML files, shipped in the module, overridable via config.** Defaults + live at `modules/shell/deny.yaml` and `modules/shell/allow.yaml`. Operators + point `extra.shell.policy.deny` / `.allow` at their own files — expected + to live in the instance directory, mounted **read-only** into the container. + Loaded **once** and cached by resolved path; the files are read-only by + design and are not meant to be edited hot. +5. **Obfuscation and interpreter escape are explicitly out of scope.** See §4.2. +6. **A malformed or missing policy file blocks everything.** Fail closed. +7. **Backgrounding (`&`) stays allowed** at `neutral` — running a long job in + the background is a legitimate thing to want. See §4.5. + +--- + +## 2. Architecture + +``` +modules/shell/ +├── __init__.py EXTENSION_META — config schema (updated) +├── __main__.py registration + dispatch (slimmed; no list loading, no Windows) +├── policy.py YAML → Policy dataclasses; loading, validation, defaults +├── validate.py parse + AST walk + rule matching → Verdict +├── deny.yaml default deny rules (neutral tier) +├── allow.yaml default allow rules (sub-neutral tier) +└── PLAN.md this file +``` + +One job per module, per CLAUDE.md §5: `policy.py` knows YAML and nothing about +tree-sitter; `validate.py` knows tree-sitter and nothing about YAML or files. +Both are pure functions over data — no I/O in `validate.py`, which makes the +test corpus in §8 trivial to write. + +The parser and the compiled policy are **module-level singletons** built once at +import / first use, not per-`register_agent`. Today `_load_blacklist()` re-reads +and re-compiles 319 lines of regex on **every AgentCycle**. Same for the policy: +load once, cache by `(path, mtime)` so an operator editing the YAML doesn't need +a restart. + +### Validation pipeline + +``` +command: str + → 1. length guard (reject > max_command_bytes) + → 2. parse (tree_sitter_bash → Tree) + → 3. structural check (reject ERROR/MISSING nodes anywhere) + → 4. construct walk (every node type checked against the tier's construct policy) + → 5. command extraction (collect every `command` node, including nested ones) + → 6. per-command rules (each resolved command matched against deny/allow rules) + → Verdict(action: allow | warn | deny, rule_id, message) +``` + +Steps 3–6 all **fail closed**. A command reaches dispatch only if nothing +objected. + +### Why the walk catches nesting for free + +`$(...)`, `` `...` ``, `<(...)`, subshells, function bodies, and loop bodies all +contain ordinary `command` nodes as descendants. A single recursive walk that +collects every `command` node in the tree therefore validates +`echo $(rm -rf /)` as **two** commands — `echo` and `rm -rf /` — with no special +casing. Confirmed in §9. + +--- + +## 3. Construct policy (step 4) + +Node types are checked against an explicit table. **Any node type not in the +table is a deny.** This matters: it means a future `tree-sitter-bash` upgrade +that adds grammar nodes fails *closed* (commands get rejected, we notice) rather +than *open* (a new syntax silently bypasses rules). + +Each YAML file carries a `constructs:` block. Proposed defaults: + +| Construct (node type) | `deny.yaml` (neutral) | `allow.yaml` (sub-neutral) | +|---|---|---| +| `command`, `command_name`, `word`, `number` | allow | allow | +| `string`, `raw_string`, `string_content` | allow | allow | +| `pipeline` (`\|`) | allow | allow | +| `list` (`&&`, `\|\|`), `;` separators | allow | allow | +| `variable_assignment`, `declaration_command` | allow | deny | +| `command_substitution` `$(…)` / `` `…` `` | allow (contents validated) | **deny** | +| `process_substitution` `<(…)` | allow (contents validated) | **deny** | +| `simple_expansion` / `expansion` (`$VAR`, `${…}`) | allow, but see §4.3 | **deny** | +| `file_redirect`, `redirected_statement` | allow + target rules | **deny** | +| `heredoc_*` | allow | deny | +| `subshell`, `compound_statement` | allow | deny | +| `if_statement`, `for_statement`, `while_statement`, `case_statement` | allow | deny | +| `function_definition` | **deny** (see §4.4) | deny | +| background `&` | **deny** (see §4.5) | deny | +| `arithmetic_expansion`, `test_command`, `[[ ]]` | allow | deny | +| background `&` | allow (§4.5) | **deny** | +| *anything else* | **deny** | **deny** | + +Only **named** nodes are checked. Anonymous tokens (`;`, `|`, `{`, `then`, +`done`, …) are governed by their named parent, so the table stays a readable +size instead of enumerating every punctuation token in the grammar. The one +exception is the bare `&` token, which has no named wrapper — it gets a +synthetic `background` construct key. + +Effect for the sub-`neutral` tier: only simple commands and pipelines of them, +with literal arguments. Every argument is a parser leaf. Injection is not +"filtered" — it is **structurally unrepresentable**. That is what retires +`{arg}` and `_ARG_CLASS`. + +--- + +## 4. Hard cases and how each is handled + +These are the reasons an AST is necessary but not sufficient. Each needs an +explicit rule; none can be waved away. + +### 4.1 Non-literal command names + +``` +$CMD arg → command_name is a simple_expansion +$(echo rm) -rf / → command_name is a command_substitution +``` +The executable name is not knowable statically. **Rule: a command whose +`command_name` is not a literal `word` is denied at `neutral` and below.** +Only `bypass_blacklist` skips this. Denying is honest; guessing is not. + +### 4.2 Interpreters and obfuscation — OUT OF SCOPE + +`python -c 'import os; os.system(...)'`, `node -e`, `perl -e`, +`echo cm0gLXJmIC8K | base64 -d | sh`, and every other way of smuggling a +command inside an argument **are not defended against here.** No recursive +re-parsing of wrapped strings, no attempt to decode encoded payloads, no +interpreter-source analysis. + +This is a deliberate boundary, and it is the honest one. A validator that +half-defends against obfuscation is worse than one that doesn't: it grows +unbounded (every new encoding, every new interpreter, every new wrapper), it +produces false positives on legitimate work, and it invites the reader to trust +a guarantee it cannot make. **The container is the security boundary** — non-root, +read-only rootfs, no LAN/Tailscale egress. This layer stops accidents and +obvious mistakes. + +What we *do* keep is whatever flat deny rules the old blocklist already had +(`bash -c *`, `sh -c *`, `python* -c *`, `curl *| sh*`) — ported as ordinary +command+flag rules in §5. They are cheap, they catch the unsubtle case, and they +cost nothing. They are not claimed to be complete. + +Consequence for the code: `validate.py` **never recurses into command text.** +No `max_reparse_depth`, no re-entrant parser. Simpler module, honest docstring. + +### 4.3 Expansions in arguments + +`rm $TARGET` and `ls $HOME/*.txt` have argument values that don't exist until +runtime. Path-based rules (§5, `path_under`) therefore cannot be evaluated. +**Rule: if a rule's matcher depends on an argument's value and that argument +contains an expansion, the rule matches (deny) rather than misses.** Conservative +by construction. A rule that only matches on command name + flags is unaffected. + +Globs (`*.txt`) are the same problem in a milder form — `rm *` in `/` is a +disaster the string matcher also never caught. Treat an unquoted `*`/`?`/`[` in +a path operand as "expands to unknown", same conservative branch. + +### 4.4 Rebinding + +`function rm { … }`, `alias rm=…`, `rm() { … }` let a later command in the same +input mean something other than what its name says. Cheapest correct answer: +**deny `function_definition` and `alias` at `neutral` and below.** Neither has a +legitimate use in a one-shot tool call. + +### 4.5 Backgrounding — allowed at `neutral` + +`foo &` is permitted. Launching a long-running script in the background +(`nohup python train.py &`) is a legitimate thing for the agent to do, and +forbidding it to close a housekeeping leak would trade a real capability for a +marginal gain. + +The leak is real but is not this layer's problem: the sandbox container is +shared for the whole instance lifetime across every caller and branch, and +`subprocess.run` only waits for the immediate bash child — so a backgrounded +process is orphaned and outlives its request. The existing consequence is +already documented in `whitelist.txt`'s header (it is why `ps aux` must never be +whitelisted: a leaked process's argv can carry secrets). That reasoning carries +forward to `allow.yaml` unchanged — `ps` and `ps -eo pid,comm` yes, `ps aux` no. + +`&` is denied at the sub-`neutral` tier, which is deny-by-default anyway. + +### 4.6 Path rules are lexical + +`path_under: [/etc]` is matched against the operand **text**, normalized +(`..` collapsed, `~` expanded, made absolute against the workspace root). It is +**not** resolved against the filesystem: symlinks are not followed, and +`cd /etc && rm passwd` is not tracked across the `&&` — `cd` changes the cwd for +the second command and the validator does not model that. Documented limitation, +not a bug to fix in this pass. The sandbox's read-only root filesystem is the +real control for absolute-path writes; these rules are defense in depth. + +--- + +## 5. Rule schema + +One schema, both files. A rule matches a **single resolved command node**. + +```yaml +version: 1 + +constructs: # §3 table; omitted keys take the tier default + command_substitution: deny + file_redirect: allow + +defaults: + max_command_bytes: 8192 + +rules: + - id: rm-recursive + action: deny # deny | warn | allow + command: rm # str or list; matched on basename + any_flag: ["-r", "-R", "--recursive", "-rf", "-fr"] + message: "recursive delete" + + - id: rm-outside-workspace + action: deny + command: [rm, shred, truncate] + path_outside: ["${workspace}"] # ${workspace} interpolated at load + message: "writes outside the workspace" + + - id: git-force-push + action: warn # replaces _DESTRUCTIVE (Phase 3) + command: git + subcommand: push + any_flag: ["-f", "--force", "--force-with-lease"] + message: "may overwrite remote history" + + - id: inline-interpreter + action: deny + command: [python, python3, node, perl, ruby, php] + any_flag: ["-c", "-e", "--command", "--eval"] + message: "inline code bypasses command policy" +``` + +Matcher fields (all optional; a rule matches when **every** present field +matches — AND): + +| Field | Meaning | +|---|---| +| `command` | executable basename. `./foo`, `/usr/bin/foo`, `foo` all → `foo`. str or list | +| `subcommand` | first non-flag, non-assignment operand (`git` **`push`**) | +| `any_flag` / `all_flags` | normalized flags: `-la` splits to `-l`,`-a`; `--x=y` splits to `--x`; everything after `--` is an operand, never a flag | +| `arg_matches` | regex every operand must match (allow rules) | +| `path_under` / `path_outside` | normalized-path prefix test (§4.6) | +| `max_args` | operand count ceiling (allow rules) | + +Allow rules invert the flag semantics — an allow entry declares the **complete** +permitted surface, and anything outside it fails: + +```yaml +# allow.yaml +rules: + - id: git-read-only + action: allow + command: git + subcommand: [status, log, diff, show, branch] + allowed_flags: ["--oneline", "--stat", "--no-color", "-n", "--graph"] + max_args: 4 + arg_matches: '^[A-Za-z0-9._/-]+$' + + - id: echo-anything + action: allow + command: echo + max_args: 8 + # no arg_matches needed: at this tier every arg is a parser leaf, + # so `echo "a; b | c"` is one command with one literal argument. +``` + +**Deny beats allow.** A command that matches an allow rule is still run through +the deny rules — same as today's "whitelisted commands are still blacklisted +unless `bypass_blacklist`". Preserved deliberately. + +Every rule needs an `id`.

Not configurable — a security layer with an "off by +accident" mode isn't one. This **inverts** current behavior: today a missing +`blacklist.txt` logs a warning and leaves the shell *unrestricted*. + +Policy files are loaded once and cached by resolved path. They are read-only by +design (mounted read-only in the container), so no `mtime` invalidation and no +hot reload — editing one requires a restart. + +**Dependencies:** add `tree-sitter>=0.25,<0.27` and `tree-sitter-bash` to +`pyproject.toml`. Pin a ceiling: because unknown node types deny (§3), a grammar +bump can turn working commands into rejections.

Rewrite `tests/test_shell.py`'s list-isolation fixtures to point at +temp YAML. +→ *verify:* full `pytest tests/` green; Phase 1 corpus passes through the real +`shell()` entry point, not just the validator; `grep -rn "blacklist\|whitelist"` +across the repo returns only `modules/ctx_tools`' unrelated token blacklist. + +**Phase 3 — fold in the warning list (optional, cuttable).** +Move the 16 `_DESTRUCTIVE` regexes into `deny.yaml` as `action: warn` rules. +They have the same substring-matching defects — `\bgit\s+reset\s+--hard\b` fires +inside a quoted commit message today. Also rewrite `_last_cmd()` (used for +exit-code annotation) to read the last `command` node of the last pipeline +instead of splitting on `|`. +→ *verify:* warning-emission tests for each ported rule + a negative test that a +quoted mention doesn't fire. + +**Docs:** `CODEBASE.md`'s `shell` entry (line ~374) and `README.md`'s line 34 +both describe the blacklist; update in Phase 2.

Grammar notes (verified, `tree-sitter-bash` via `tree_sitter` 0.26) + +Confirmed parses this plan depends on: + +- `echo "i"; echo am; echo harmless` → three sibling `command` nodes under + `program`, `;` as separate tokens. **No error.** +- `git commit -m "msg with ; and | chars"` → the metacharacters land in + `string_content`, a leaf under `string`. Data, not structure. +- `echo $(rm -rf /)` → `command_substitution` containing a full `command` node. + A recursive walk sees `rm` without special casing. Same for `` `id` `` and + `<(id)`. +- `$CMD arg` and `$(echo rm) -rf /` → `command_name` wrapping a + `simple_expansion` / `command_substitution` instead of a `word`. Detectable, + hence §4.1. +- `ls > /etc/passwd` → `redirected_statement` { `command`, `file_redirect` }. + Redirect targets are reachable for `path_under` rules. +- `ls &` → `&` is a **sibling** of `command` under `program`, not a child. + The background check must look at siblings. +- `ls -la --color=auto x` → flags arrive as undifferentiated `word` nodes; the + grammar does **not** split `-la` or `--color=auto`. Flag normalization is our + job (§5), including POSIX `--` end-of-options (`rm -- -rf` → `-rf` is an + operand, verified). +- `ls;;;` → `ERROR` node, `has_error == True`. Step 3 catches it. +- Empty / whitespace-only input parses clean to an empty `program` — must be + rejected explicitly, not by `has_error`. + +--- + +## 10. What this does not do + +State plainly, so nobody mistakes the scope: + +- **It is not a sandbox.** The container (non-root, read-only rootfs, iptables + egress rules, internal-only network) is the security boundary. This is defense + in depth and a UX improvement — a policy layer that stops obvious mistakes and + stops *lying* about what it blocked. +- **It cannot see runtime values.** `$VAR`, glob expansion, and command + substitution output are unknowable statically. §4.3's conservative branch is a + deliberate false-positive trade, not a solution. +- **It does not defeat obfuscation** (§4.2). Base64, encoded payloads, + interpreter one-liners, and wrapped commands are explicitly out of scope. The + flat rules ported from the old blocklist catch the unsubtle cases and nothing + more is claimed. +- **It does not sandbox permitted programs.** If `python foo.py` is allowed, the + script does whatever it wants. Same for `make`, `npm run`, `git` hooks. +- **It does not track backgrounded processes.** `&` is allowed (§4.5); orphaned + processes outliving their request remain a known property of the shared + sandbox container. +- **It does not moderate output.** The existing `whitelist.txt` warning holds: + allowing `echo` guarantees `echo` can't damage the system, not that a caller + won't say something objectionable through it. + +--- + +## 11. Resolved decisions + +1. **Obfuscation / interpreter escape: out of scope.** No recursive parsing of + wrapped command strings, no base64 decoding. Flat ported rules only.

Write tools require prior `view()` to prevent blind overwrites. `write_file`/`edit_file` are sandboxed to `workspace/` only. `view`/`grep`/`glob_search` can additionally reach any directory listed in `filesystem.read_only_paths` in config.yaml (e.g. `/app` for the agent's own source in the container) — read-only, never writable; nothing outside workspace/ + that whitelist is reachable at all. `view()` detects image files by extension (`.jpg/.jpeg/.png/.gif/.webp`) and returns them as `IMAGE_BLOCK_PREFIX` sentinels; `agent._execute_tool` unwraps these, converts to PNG via Pillow, and injects a follow-up user turn with an `image_url` block. If PNG conversion fails (Pillow unavailable), the image path falls back to a plain text description rather than sending an unconverted format to the backend (which would cause a misleading "mmproj is missing" backend error). -### `shell` — `shell` tool. Runs in workspace directory. Maintains a blacklist of dangerous commands (`blacklist.txt`, substring glob match) plus a `whitelist.txt` (glob, but **fullmatch**-anchored, not substring — see file header) of commands allowed for reduced-permission callers. Four permission levels gate access, configured via `extra.shell.permissions` (defaults: `use_whitelist=10`, `neutral=45`, `bypass_blacklist=90`, `access_backend=80`), all resolved from the actual caller (`agent.caller.permission_level`, snapshotted once per cycle like `modules/sysops` does) rather than a static config value — fixes a bug where `backend_access=True`'s guard read `agent.config.permissions.level`, an attribute `PermissionsConfig` never defines (it only has `minimal_tokens: bool`). Callers below `neutral` may only run whitelisted commands; callers below `bypass_blacklist` are still blacklist-checked; `backend_access=True` requires `access_backend`. The tool is registered with `min_permission=use_whitelist` (not a fixed 45), so whitelist-tier callers can now see/call it at all — enforcement of what they can actually run happens inside `_dispatch()`. +### `shell` — `shell` tool. Runs in workspace directory. Linux only (PowerShell support and `_normalize_windows` were removed with the container refactor). + +**Command policy is AST-based (v2).** `validate.py` parses the command with `tree-sitter-bash` and checks each *resolved command* in it separately; `policy.py` compiles the rules from YAML. This replaced substring-glob `blacklist.txt` / `whitelist.txt`, which could not distinguish a command from a quoted argument containing the same text — `echo "i"; echo "am"; echo "harmless"` was blocked, and `git commit -m "don't rm -rf your repo"` was too. Design of record: `modules/shell/PLAN.md`. + +- Two policy files, both shipped in the module, overridable via `extra.shell.policy.{deny,allow}` (typically pointed at the instance dir, mounted read-only): `deny.yaml` (`default_action: allow` — deny-list, for callers at/above `neutral`) and `allow.yaml` (`default_action: deny` — allow-list with per-command `subcommand`/`allowed_flags`/`max_args`/`arg_matches` constraints, for callers below `neutral`). Deny beats allow. Loaded once, cached by `(path, workspace)`. +- Rules match on parsed structure: `command` (basename), `subcommand`, `any_flag`/`all_flags`, `no_operands`, `path_under`/`path_outside`/`redirect_under`. Flags are normalized, so `-rf`, `-fr` and `-r -f` are one rule. `action: warn` replaced the old `_DESTRUCTIVE` regex list — warnings run and prefix the output. +- Each YAML also carries a `constructs:` map of permitted bash node types. **Anything not listed is denied**, so a `tree-sitter-bash` grammar upgrade fails closed; hence the version pin in `pyproject.toml`. `function_definition` is denied at every tier (rebinding `rm()` would defeat a name-based rule). At the allow-list tier substitutions, expansions, redirects and backgrounding are all denied, which is what makes injection structurally impossible and retires the old `{arg}` character-class hack — quoted text is a parser leaf, so callers get their metacharacters back as data. +- **Fails closed:** a missing/malformed policy blocks every command (the old `blacklist.txt` did the opposite — missing file meant unrestricted). Not configurable. Also denied: commands whose name isn't a literal word (`$CMD`, `$(echo rm)`), and any input with a parse error. +- **Explicitly out of scope:** obfuscation and interpreter escape. No recursive re-parsing of `bash -c` payloads, no base64 decoding. Flat rules catch the unsubtle cases (`bash -c`, `python -c`, pipe-to-shell via `no_operands`); nothing more is claimed. Backgrounding (`&`) is allowed at `neutral` so the agent can start long jobs. The container is the security boundary. +- Four permission levels gate access, configured via `extra.shell.permissions` (defaults: `use_whitelist=10`, `neutral=45`, `bypass_blacklist=90`, `access_backend=80`), all resolved from the actual caller (`agent.caller.permission_level`, snapshotted once per cycle like `modules/sysops` does) rather than a static config value — fixes a bug where `backend_access=True`'s guard read `agent.config.permissions.level`, an attribute `PermissionsConfig` never defines (it only has `minimal_tokens: bool`). The key names still say whitelist/blacklist for config compatibility; they now select which policy file applies. `bypass_blacklist` skips policy checks entirely. The tool is registered with `min_permission=use_whitelist`, so allow-list-tier callers can see/call it at all — enforcement of what they can actually run happens inside `_dispatch()`. +- Tests: `tests/test_shell_policy.py` is a must-deny/must-allow corpus run against the **real shipped YAML**, including a check that every shipped rule has a test case proving it fires. `tests/test_shell.py` covers tier routing and fail-closed behaviour against throwaway fixture policies. ### `web` — `web_search` (DuckDuckGo via `ddgs`) and `open_url` (Playwright, headless by default; `headless=False` for captchas). diff --git a/README.md b/README.md index f5c4b7d..fcec1a9 100644 --- a/README.md +++ b/README.md @@ -31,7 +31,7 @@ A context-efficient agentic assistant framework.

This replaced substring-glob `blacklist.txt` / `whitelist.txt`, which could not distinguish a command from a quoted argument containing the same text — `echo "i"; echo "am"; echo "harmless"` was blocked, and `git commit -m "don't rm -rf your repo"` was too. Design of record: `modules/shell/PLAN.md`. - Two policy files, both shipped in the module, overridable via `extra.shell.policy.{deny,allow}` (typically pointed at the instance dir, mounted read-only): `deny.yaml` (`default_action: allow` — deny-list, for callers at/above `neutral`) and `allow.yaml` (`default_action: deny` — allow-list with per-command `subcommand`/`allowed_flags`/`max_args`/`arg_matches` constraints, for callers below `neutral`). Deny beats allow. Loaded once, cached by `(path, workspace)`. +- **Policies compose via `extends:`** — `builtin:allow`, `builtin:deny`, or a path (relative to the extending file). An instance adds one rule without vendoring the whole file. Base rules come first, then the child's; a matching `id` replaces a base rule, `disable: [id, ...]` drops one (unknown ids raise, so a typo can't silently leave a rule in force). `default_action` and `constructs` are inherited, declared constructs merge over the base, and a child cannot flip `default_action` (the two postures use different rule schemas). Cycles raise. Worked example: `modules/shell/example.instance-allow.yaml` (re-enables `ps` with its `-o` columns constrained to non-argv fields). +- `allow.yaml`'s bar is "a stranger on Discord could run this": nothing on it can read a file, the network, or the environment, so the only data enterable at that tier is text the caller typed. That excludes `cat`/`grep`/`ls`/`ps`/`env`/`whoami`. Enforced by `max_args: 0` on the stdin filters (they cannot name a file) and explicit `allowed_flags` everywhere (omitting the key permits no flags — which is what keeps `sort -o FILE`, `date -s`, and `wc --files0-from=F` out). Deliberately stricter than the sandbox's actual threat model; loosen per-instance via `extends`, not by editing it. - Rules match on parsed structure: `command` (basename), `subcommand`, `any_flag`/`all_flags`, `no_operands`, `path_under`/`path_outside`/`redirect_under`. Flags are normalized, so `-rf`, `-fr` and `-r -f` are one rule. `action: warn` replaced the old `_DESTRUCTIVE` regex list — warnings run and prefix the output. - Each YAML also carries a `constructs:` map of permitted bash node types. **Anything not listed is denied**, so a `tree-sitter-bash` grammar upgrade fails closed; hence the version pin in `pyproject.toml`. `function_definition` is denied at every tier (rebinding `rm()` would defeat a name-based rule). At the allow-list tier substitutions, expansions, redirects and backgrounding are all denied, which is what makes injection structurally impossible and retires the old `{arg}` character-class hack — quoted text is a parser leaf, so callers get their metacharacters back as data. - **Fails closed:** a missing/malformed policy blocks every command (the old `blacklist.txt` did the opposite — missing file meant unrestricted). Not configurable. Also denied: commands whose name isn't a literal word (`$CMD`, `$(echo rm)`), and any input with a parse error. diff --git a/TinyCTX/modules/shell/allow.yaml b/TinyCTX/modules/shell/allow.yaml index a03d81f..d39b975 100644 --- a/TinyCTX/modules/shell/allow.yaml +++ b/TinyCTX/modules/shell/allow.yaml @@ -5,12 +5,47 @@ # must be covered by some rule here, and then deny.yaml still gets a say # (deny beats allow, same as the old whitelist behaviour). # -# An allow rule must account for the command COMPLETELY: +# ---- What "safe" means here ---- +# +# The bar for this file: you could hand this tier to a stranger on Discord and +# let them run it against your machine, and nothing bad happens.

hence the version pin in `pyproject.toml`. `function_definition` is denied at every tier (rebinding `rm()` would defeat a name-based rule). At the allow-list tier substitutions, expansions, redirects and backgrounding are all denied, which is what makes injection structurally impossible and retires the old `{arg}` character-class hack — quoted text is a parser leaf, so callers get their metacharacters back as data. - **Fails closed:** a missing/malformed policy blocks every command (the old `blacklist.txt` did the opposite — missing file meant unrestricted). Not configurable. Also denied: commands whose name isn't a literal word (`$CMD`, `$(echo rm)`), and any input with a parse error. - **Explicitly out of scope:** obfuscation and interpreter escape. No recursive re-parsing of `bash -c` payloads, no base64 decoding. Flat rules catch the unsubtle cases (`bash -c`, `python -c`, pipe-to-shell via `no_operands`); nothing more is claimed. Backgrounding (`&`) is allowed at `neutral` so the agent can start long jobs. The container is the security boundary. -- Four permission levels gate access, configured via `extra.shell.permissions` (defaults: `use_whitelist=10`, `neutral=45`, `bypass_blacklist=90`, `access_backend=80`), all resolved from the actual caller (`agent.caller.permission_level`, snapshotted once per cycle like `modules/sysops` does) rather than a static config value — fixes a bug where `backend_access=True`'s guard read `agent.config.permissions.level`, an attribute `PermissionsConfig` never defines (it only has `minimal_tokens: bool`). The key names still say whitelist/blacklist for config compatibility; they now select which policy file applies. `bypass_blacklist` skips policy checks entirely. The tool is registered with `min_permission=use_whitelist`, so allow-list-tier callers can see/call it at all — enforcement of what they can actually run happens inside `_dispatch()`. +- **Tiers are config, not code.** `extra.shell.min_permission` (default 30) is the level below which the tool isn't offered. `extra.shell.policies` is a flat list where each entry carries the level at which a caller *outgrows* it: `[{policy: builtin:allow, applies_below: 45}, {policy: builtin:deny, applies_below: 90}]`. A caller is subject to every entry whose `applies_below` they're under — so level 20 gets both, 50 gets the deny-list only, 95 gets nothing. Omit `applies_below` for a policy that binds everyone (no unrestricted tier at all). `policy:` accepts `builtin:allow`, `builtin:deny`, a name relative to the config dir, or an absolute path. `_dispatch()` does not know which policy is an allow-list and which is a deny-list — each file declares that via `default_action` — so tier selection is one comparison per policy. + - Note what the shape *can't* express: a policy binding a higher-privileged caller while sparing a lower one. That's incoherent; a flat threshold list makes it unrepresentable. An earlier band-table design (`tiers: [{min_level, apply: [...]}]`) could express it, which is why it was replaced. Before that it was a hardcoded if-chain plus `use_whitelist`/`neutral`/`bypass_blacklist` — three fixed tiers, unextendable. **Those three keys are now an error**, not ignored: silently dropping a `use_whitelist: 90` someone set to lock the shell down would loosen access. +- `extra.shell.permissions.access_backend` (default 80) stays a scalar — it gates *where* a command runs (main container vs sandbox), orthogonal to which policy applies. Levels resolve from the actual caller (`agent.caller.permission_level`, snapshotted once per cycle like `modules/sysops` does) rather than a static config value — fixes a bug where `backend_access=True`'s guard read `agent.config.permissions.level`, an attribute `PermissionsConfig` never defines (it only has `minimal_tokens: bool`). +- A policy that won't load blocks **every** caller, including one who'd otherwise be unrestricted — a broken config can't tell us whether the failed entry was the one that would have bound them. - Tests: `tests/test_shell_policy.py` is a must-deny/must-allow corpus run against the **real shipped YAML**, including a check that every shipped rule has a test case proving it fires. `tests/test_shell.py` covers tier routing and fail-closed behaviour against throwaway fixture policies. ### `web` — `web_search` (DuckDuckGo via `ddgs`) and `open_url` (Playwright, headless by default; `headless=False` for captchas). @@ -425,6 +428,16 @@ An *instance* is a self-contained directory holding one agent's config, workspac ``` / e.g. ~/.tinyctx, or anywhere via --dir ├── config.yaml Loaded by default from here (workspace.path / data.path default relative to this file) +├── config/ Extra config too big or structured to inline into config.yaml — currently +│ the shell module's policy YAML.

The three constants collapse: `use_whitelist` is the lowest band +(and the tool's `min_permission`), `bypass_blacklist` is `apply: []`, `neutral` +stops existing as a concept. + +**What makes it collapse** is that each policy file already declares its own +posture via `default_action`. So `_dispatch()` doesn't need to know which file +is an allow-list and which is a deny-list — it runs a list in order and every +entry must pass. Losing that distinction from the code is the whole trick; +without it, "apply these N policies" wouldn't type-check as a concept. + +Details that matter: + +- **Removed keys are an error, not ignored.** A config still carrying + `use_whitelist: 90` blocks the shell with a migration message. Ignoring it + would silently *loosen* access for exactly the person who had raised it to + lock things down — a security bug in the worst direction. +- **A broken table blocks every caller, including an `apply: []` band.** If the + table won't load we don't know which band a caller is in, so we can't know + they were meant to be unrestricted. +- **Tier `apply` paths must be absolute** (or `builtin:*`). Unlike `extends:`, + a tier table has no file to resolve a relative path against, and falling back + to the process CWD would make policy selection depend on how the agent was + launched. +- `access_backend` stays a scalar. It gates *where* a command runs, not which + policy applies to it — a genuinely different axis, and folding it into the + table would have been symmetry for its own sake. + +**Known limitation, not addressed.** The axis is still one-dimensional. +`permission_level` answers *who*, but shell risk is *who × where*: the same +user at level 50 gets identical access in a private DM and in a public channel +with 400 people. `modules/memory` hit this and solved it with scopes +(`global` / `guild:x` / `user:bob`) resolved from `SessionEnvironment`, which +this module receives and ignores. Making band selection a function of +`(caller_level, env)` rather than `caller_level` is the next step if that +becomes the pain point; the table is the necessary foundation either way. + +--- + +## 13. Thresholds, not bands (supersedes §12) + +§12's band table fixed the right problem the wrong way. Bands made tiers data, +but kept a structure the domain doesn't have: a list of levels, each owning a +nested list of policies. Two things fell out of that. + +**It could express nonsense.** Bands `30: [A]`, `45: [A, B]`, `70: [A]` say a +caller at 45 is bound by B and a caller at 70 is not. Policy application should +be monotonic in privilege — anything else is a misconfiguration nobody wants, +and the table happily represented it. + +**It buried the actual datum.** What decides whether a policy applies to you is +one number: the level at which you outgrow it. Bands scattered that across the +table (a policy's threshold was implicit in which bands did and didn't list +it), so adding a policy meant editing several entries. + +Put the number on the policy instead: + +```yaml +min_permission: 30 +policies: + - {policy: builtin:allow, applies_below: 45} + - {policy: builtin:deny, applies_below: 90} +``` + +A caller is subject to every entry whose `applies_below` they are under. Level +20 gets both, 50 gets the deny-list, 95 gets nothing. Adding a policy is one +line. Non-monotonic application is unrepresentable. `min_permission` becomes +its own scalar rather than being inferred from "the lowest band", which it only +ever coincidentally was. + +`PolicySet.for_level()` is now a filter over one comparison, and `Band` / +`TierTable` are gone along with the None-vs-empty-tuple distinction they needed +("below every band" versus "unrestricted") — `min_permission` handles the +former in the tool handler, so `()` unambiguously means unrestricted. + +### 13.1 The mount bug this exposed + +Every instruction written up to §12 — "point it at a file in your instance +directory, mounted read-only" — was **broken under Docker**. compose.yaml +mounted exactly four things (`workspace/`, `data/`, `config.yaml`, `TinyCTX/`), +so an instance-local policy file was not visible inside the container at all. +The feature worked only for bare-metal launches. + +Fixed by giving the instance a dedicated extra-config directory: + +- `/config/` on the host, bound **read-only** at `/app/config`. + Deliberately not the instance directory itself, which holds `.env` and + `data/` — neither belongs in the container as config. +- `compose_env()` exports the host path as `TINYCTX_CONFIG_DIR` (the bind + source); compose.yaml sets `TINYCTX_CONFIG_DIR_PATH=/app/config` for the code + side.
