Aji" Date: Thu, 15 Oct 2026 12:23:56 +0700 Subject: [PATCH 04/19] security(review): admit judge output as untrusted input; cache keyed by the exact prompts (#644) (#652) judge::admit clears rule_id, bounds text and count, drops files and lines the diff does not contain; applied to review and scan. The Packet now carries the finished hardened prompts, and the review cache moves behind HttpJudge keyed by those prompts, storing the raw model answer so ignore.rules, min_severity and rules are applied on cache hits too. Scan batches get an untrusted-data fence.

Output of `cora review` is unchanged. The review pipeline now has an end-to-end test with a fake judge (no network), and the `llm` module no longer prints: spinners moved to `progress::Spinner` and `llm::review_diff` / `llm::scan_files` take an events observer like the stream variant. diff --git a/src/commands/scan.rs b/src/commands/scan.rs index 3fe674c..3bfb492 100644 --- a/src/commands/scan.rs +++ b/src/commands/scan.rs @@ -7,6 +7,7 @@ use tracing::debug; use crate::config::schema::Config; use crate::engine::ReviewIssue; use crate::engine::finalize::{self, HistoryEntry, ShapeOptions}; +use crate::engine::judge::admit; use crate::engine::postprocess::{Source, dropped_warning, postprocess_report}; use crate::engine::scanner::{FileEntry, batch_files, format_batch_for_prompt, walk_project}; use crate::engine::types::TokenUsage; @@ -194,7 +195,10 @@ pub async fn execute_scan( spinner.finish(); match scanned { Ok((issues, _summary, tokens)) => { - all_issues.extend(issues); + // The model's answer is untrusted: only files of this batch, + // bounded text, no deterministic markers (#644). + let batch_paths: Vec = batch.iter().map(|f| f.path.clone()).collect(); + all_issues.extend(admit(issues, &batch_paths, &Source::Files(batch))); total_tokens = match (total_tokens, tokens) { (Some(mut acc), Some(t)) => { acc.input_tokens += t.input_tokens; diff --git a/src/engine/cache.rs b/src/engine/cache.rs index 61a061d..4f53e8a 100644 --- a/src/engine/cache.rs +++ b/src/engine/cache.rs @@ -73,13 +73,20 @@ fn migrate_legacy_cache_dir(new_dir: &std::path::Path) { } } -/// Compute SHA-256 hex digest of the diff content + config parameters. +/// Compute SHA-256 hex digest of the judge input (the exact prompts) + config +/// parameters. /// Includes model, provider, base_url, and temperature so config changes /// invalidate the cache (e.g., switching providers with the same model name). #[allow(clippy::format_collect)] -fn cache_key(diff: &str, model: &str, temperature: f32, provider: &str, base_url: &str) -> String { +fn cache_key( + key_text: &str, + model: &str, + temperature: f32, + provider: &str, + base_url: &str, +) -> String { let mut hasher = Sha256::new(); - hasher.update(diff.as_bytes()); + hasher.update(key_text.as_bytes()); hasher.update(model.as_bytes()); hasher.update(provider.as_bytes()); hasher.update(base_url.as_bytes()); @@ -93,14 +100,14 @@ fn cache_key(diff: &str, model: &str, temperature: f32, provider: &str, base_url /// Returns `None` if no cache exists or if the cache entry has expired /// (based on `ttl` in minutes). pub fn get_cached_review( - diff: &str, + key_text: &str, model: &str, temperature: f32, ttl: u64, provider: &str, base_url: &str, ) -> Option { - let hash = cache_key(diff, model, temperature, provider, base_url); + let hash = cache_key(key_text, model, temperature, provider, base_url); let dir = cache_dir().ok()?; let path = dir.join(format!("{hash}.json")); @@ -139,7 +146,7 @@ pub fn get_cached_review( /// Save a review response to the cache. pub fn save_cached_review( - diff: &str, + key_text: &str, model: &str, temperature: f32, response: &ReviewResponse, @@ -149,7 +156,7 @@ pub fn save_cached_review( let dir = cache_dir()?; std::fs::create_dir_all(&dir).map_err(CoraError::CacheIo)?; - let hash = cache_key(diff, model, temperature, provider, base_url); + let hash = cache_key(key_text, model, temperature, provider, base_url); let path = dir.join(format!("{hash}.json")); let now = SystemTime::now() diff --git a/src/engine/judge.rs b/src/engine/judge.rs index f18242e..d22694a 100644 --- a/src/engine/judge.rs +++ b/src/engine/judge.rs @@ -3,37 +3,43 @@ //!

Aji" Date: Thu, 15 Oct 2026 12:28:48 +0700 Subject: [PATCH 05/19] fix(scan): run the same deterministic family as review; scan judge seam (#645) (#653) deterministic::run_files serves whole files (scan, MCP snippet check) the way run serves diffs, so built-in and custom rules now fire in scan. ScanJudge (HttpScanJudge, NoJudge) makes the batch loop testable without a network. DEFAULT_BATCH_TOKEN_BUDGET is renamed to CHAR_BUDGET and the docs state which review flags scan lacks.

From 2da83cec0bbbccacf6a1971fba20071669a13a25 Mon Sep 17 00:00:00 2001 From: "Anaz S. Aji" Date: Thu, 15 Oct 2026 12:41:45 +0700 Subject: [PATCH 07/19] feat(mcp): agent-as-reviewer tools and a cora-review skill; fix review_diff runtime panic (#647) (#655) cora.review_prepare/review_finalize and cora.scan_prepare/scan_finalize let the calling agent be the judge with no LLM configured in cora. Finalize is stateless and validates the agent's findings through judge::admit. cora install also installs a /cora-review skill for Claude Code. Also fixes cora.review_diff panicking with 'Cannot start a runtime from within a runtime': handlers now block via block_in_place.

Scan also has a judge seam (`judge::ScanJudge`, with `HttpScanJudge` and `NoJudge`) so the batch loop is tested without a network, and `DEFAULT_BATCH_TOKEN_BUDGET` is renamed `DEFAULT_BATCH_CHAR_BUDGET` (it was always a character count). `docs/cli-reference.md` now states which review flags scan does not have. diff --git a/src/mcp/agent_tools.rs b/src/mcp/agent_tools.rs index 444d938..1384c1b 100644 --- a/src/mcp/agent_tools.rs +++ b/src/mcp/agent_tools.rs @@ -157,6 +157,18 @@ fn parse_agent_issues(value: Option<&Value>) -> Result<(Vec, usize) Ok((ok, rejected)) } +/// Tells the agent when `rules_engine.max_findings` hid deterministic findings +/// that `*_prepare` listed, instead of letting them vanish unexplained. +fn not_shown_note(dropped: usize, config: &crate::config::schema::Config) -> Value { + if dropped == 0 { + return Value::Null; + } + Value::String(format!( + "{dropped} more deterministic findings are not shown (rules_engine.max_findings = {}; raise it or set 0 to show all).", + config.rules_config.max_findings + )) +} + fn diff_param(params: &Value) -> Result<&str, ToolResult> { let diff = params .get("diff") @@ -215,7 +227,12 @@ pub fn review_prepare(params: &Value) -> ToolResult { "system_prompt": packet.prompts.system, "user_prompt": packet.prompts.user, "valid_files": packet.valid_files, + "deterministic_findings_total": deterministic.len(), "deterministic_findings": deterministic, + "deterministic_findings_note": format!( + "cora.review_finalize shows at most rules_engine.max_findings = {} deterministic findings (most severe first) and reports the rest as `not_shown`.", + config.rules_config.max_findings + ), "response_schema": response_schema(), })) } @@ -287,6 +304,8 @@ pub fn review_finalize(params: &Value) -> ToolResult { "should_block": should_block, "rejected_items": rejected, "dropped_by_validation": dropped_by_validation, + "not_shown": response.dropped_findings, + "not_shown_note": not_shown_note(response.dropped_findings, &config), "issues": response.issues.iter().map(|i| json!({ "title": i.title, "severity": i.severity.label(), @@ -506,6 +525,7 @@ pub fn scan_finalize(params: &Value) -> ToolResult { "rejected_items": rejected, "dropped_by_validation": dropped_by_validation, "not_shown": dropped, + "not_shown_note": not_shown_note(dropped, &config), "issues": all.iter().map(|i| json!({ "title": i.title, "severity": i.severity.label(), @@ -773,4 +793,36 @@ mod tests { "+def add(a, b):\n", "+ return a + b\n", ); + + #[test] + fn capped_deterministic_findings_are_reported_not_silently_hidden() { + // 7 TODO comments, default cap 5: prepare lists all, finalize says 2 are hidden. + let mut diff = String::from(concat!( + "diff --git a/lib.rs b/lib.rs\n", + "new file mode 100644\n", + "--- /dev/null\n", + "+++ b/lib.rs\n", + "@@ -0,0 +1,7 @@\n", + )); + for n in 0..7 { + diff.push_str(&format!("+// TODO item {n}\n")); + } + let prep = as_json(&review_prepare(&json!({ "diff": diff }))); + assert_eq!(prep["deterministic_findings_total"], 7); + assert!( + prep["deterministic_findings_note"] + .as_str() + .unwrap() + .contains("not_shown") + ); + let out = as_json(&review_finalize(&json!({ "diff": diff, "issues": [] }))); + assert_eq!(out["total_issues"], 5); + assert_eq!(out["not_shown"], 2); + assert!( + out["not_shown_note"] + .as_str() + .unwrap() + .contains("max_findings") + ); + } } diff --git a/src/mcp/tools.rs b/src/mcp/tools.rs index 9b16163..a56e1f1 100644 --- a/src/mcp/tools.rs +++ b/src/mcp/tools.rs @@ -824,6 +824,7 @@ fn handle_review_diff(params: &serde_json::Value) -> ToolResult { "summary": response.summary, "total_issues": response.issues.len(), "should_block": should_block, + "not_shown": response.dropped_findings, "issues": response.issues.iter().map(|i| serde_json::json!({ "title": i.title, "severity": i.severity.label(), From 5dda80c6155f2352346285543de6a7530b00d9e2 Mon Sep 17 00:00:00 2001 From: "Anaz S.

Aji" Date: Fri, 16 Oct 2026 09:25:28 +0700 Subject: [PATCH 18/19] docs(agents): align AGENTS.md with the fleet baseline v1.1 (#670) ## What Rewrite `AGENTS.md` to the fleet baseline structure (public variant): repo-specific notes first (build and test commands, the conventions CI enforces, gotchas), then the session-start ritual and the workflow summary. The "Commits & PRs" section from #667 is removed: it spelled out message-policy text that belongs in the team standard, not in a repo-visible file. ## Why The baseline keeps `AGENTS.md` generic and policy-free (ritual, workflow, continuity) and enforces message hygiene with tooling instead. #667 predates that clarification. ## Testing - Docs-only. Rendered and read through; no internal room names or paths (public repo wording), no credentials. - Branch name, PR body sections and sign-off follow what CI checks; CI results are on this PR.

An attribute that carries its item on the same line (`#[cfg(test)] fn helper() {}`) no longer exempts the NEXT line, and an attribute inside a block comment is not an attribute. `bug-println` is also skipped in `main.rs`, `src/bin/`, `examples/` and `benches/`.

New module `engine::test_context`. - **`rules_engine.max_findings` now defaults to 50, and Critical/Major findings are never hidden.** The old default of 5 could hide serious findings (a module with 7 critical findings showed 5) and made agents and users misread a capped list as the full picture. The cap now limits only the noise: it keeps every Critical and Major finding and fills the remaining slots with the most severe Minor/Info ones, still reporting how many were not shown. On a real Rust codebase the unfiltered list was up to 2400 findings, 88% `bug-unwrap`, so unlimited is not the default. Set `max_findings: 0` (or `null`) for no cap.
