Important for first-run experience but difficult to test without filesystem mocking. + +--- + +## Part 3: Structural Test Gaps (not captured by line coverage) + +### A. No integration test for the full hook lifecycle + +The system has 43 test files, but none test the complete hook lifecycle: `session-start` -> `prompt-submit` (N times) -> `pre-tool` -> `post-tool` -> `session-end`. This is the actual usage pattern and would catch interaction bugs between hooks (e.g., atoms accumulated in `hook_session_atoms` during prompt-submit being correctly consumed by session-end Hebbian learning). + +### B. No test for concurrent hook execution + +In practice, multiple hooks can fire in rapid succession (e.g., `prompt-submit` immediately followed by `pre-tool`). The Brain singleton and SQLite WAL mode should handle this, but there are no concurrency tests for the hook path. + +### C. No test for context budget integration with hooks + +The `_hook_budget()` function calculates a token budget (2% of 200K = 4,000 tokens), but no test verifies that hook output actually fits within this budget. If the context budget compression fails or produces oversized output, it could blow up the Claude Code context window. + +### D. No test for region diversity cap in recall + +The `region_diversity_cap = 2` setting in config limits atoms per region in recall results. This is tested in `test_retrieval.py` but not in the integration path through `brain.recall()` -> hook output. + +### E. No negative test for synapse type weight coherence + +The `SynapseTypeWeights` dataclass has 8 fields, and the `RetrievalEngine.__init__` builds a lookup dict by replacing `-` with `_` in relationship names. If a new synapse type is added to `RELATIONSHIP_TYPES` without a corresponding weight, it silently falls back to 0.5. A test should verify all types have explicit weights. + +--- + +## Part 4: Hebbian Architecture & Recall Quality Review + +### Assessment: The Learning System Is Well-Designed + +After reviewing `retrieval.py`, `learning.py`, `synapses.py`, `consolidation.py`, and `config.py`, the Hebbian architecture is sound and implements several biologically-grounded mechanisms correctly. All items from the improvement plan v2 (Waves 1-4) are confirmed implemented. + +### What the system does well: + +1. **BCM multiplicative increment** (`synapses.py:816`): `strength + increment * (1 - strength)` correctly implements diminishing returns at high strength. This prevents synapse saturation. + +2. **Proportional LTD** with floor: `strength * (1 - ltd_fraction)` with `MIN(ltd_min_floor, ...)` prevents immortal weak synapses. Well-calibrated at 15% per cycle. + +3. **Refractory gating** (`retrieval.py:743`): Visited set gates frontier expansion only, preserving superposition (convergent path additivity). This is the correct biological interpretation. + +4. **Fanout normalization** (`retrieval.py:712`): `1/sqrt(fanout)` using pre-filter degree penalizes hubs correctly. + +5. **Multi-signal scoring** (`retrieval.py:872-881`): 8 signals with configurable weights (vector=0.30, spread=0.25, BM25=0.12, confidence=0.12, importance=0.11, recency=0.08, frequency=0.02, newness=0.15 bonus). Well-balanced. + +6. **Inhibitory exclusion** (`synapses.py:707-723`): `contradicts`, `supersedes`, `warns-against`, and `encoded-with` are excluded from Hebbian strengthening. Inhibitory-only pairs don't trigger new `related-to` creation. + +7. **Cue overload protection** (`synapses.py:792-807`): `max_new_pairs_per_session=50` prevents O(n^2) hub formation in large sessions. + +8. **Temporal weighting** (`synapses.py:775-784`): Pairs within 300s window get full increment; distant pairs get 0.5x. Good implementation of temporal contiguity. + +9. **Synaptic Tagging and Capture** (`config.py:109-118`): STC with `stc_tagged_strength=0.25` and `stc_capture_window_days=14` implements Frey & Morris (1997) correctly. + +10. **Hybrid decay** (`config.py:201-212`): Exponential-to-power-law transition at 90 days implements Wixted & Ebbesen (1991) for heavy-tail preservation. + +### Areas for improvement in recall quality: + +#### Medium Priority + +**M1 — Session priming boost is very small (0.05)** + +`_SESSION_PRIME_BOOST = 0.05` (`retrieval.py:82`) means atoms seen earlier in the session barely register as seeds. Since these atoms already proved relevant, a value of 0.10-0.15 would better implement working-memory priming without overwhelming genuine vector matches. The current value is below `min_activation = 0.1`, meaning primed atoms that don't match the vector query won't even propagate through spreading activation. + +**M2 — No reconsolidation on re-access** + +When an atom is recalled and then the user provides feedback or modifies related knowledge, the system doesn't update the atom's embedding or re-evaluate its synapses. Biological memory undergoes reconsolidation when re-activated — the act of retrieval makes a memory temporarily labile and subject to updating. Adding a lightweight reconsolidation check (re-run auto_link on high-confidence recalls) would improve graph quality over time. + +**M3 — Encoded-with synapses are not created** + +The `encoded-with` synapse type exists in the schema (`config.py:47`) with weight 0.2, but no code path creates these synapses. They're designed for contextual binding (encoding specificity principle — Tulving 1973) but are never populated. If atoms stored in the same session were linked with `encoded-with`, recall of one would weakly activate session-mates, implementing context-dependent retrieval beyond the current session priming. + +#### Low Priority + +**L1 — No depth-aware decay weighting** + +`retrieval.py:726`: `self._cfg.decay_factor` is applied as a constant 0.85 per hop. Since `current_activation` at depth 2 already incorporates the depth-1 decay, this compounds correctly (0.85^2 = 0.7225 total at depth 2). However, the system could benefit from a depth-aware decay schedule (e.g., steeper decay at greater depths) to more aggressively penalize distant associations and keep the result set tightly focused around the query. + +**L2 — No primacy/recency effect in session Hebbian learning** + +All atoms in a session are treated equally for Hebbian learning. Biological memory shows primacy (first items) and recency (last items) effects. Weighting the first and last few atoms in a session more heavily would improve learning signal quality. + +**L3 — Contradiction detection is heuristic-only** + +`learning.py:996-1099`: The contradiction detector uses keyword matching (negation words, antonym pairs, value assertions). This catches obvious contradictions but misses subtle ones. Since the system already has an embedding engine, comparing the semantic divergence of assertion-bearing sub-clauses would improve precision. + +--- + +## Part 5: Prioritized Recommendations + +### Tier 1 — High Impact, Achievable + +1. **Test the CLI hook lifecycle end-to-end** — One integration test covering session-start through session-end with Hebbian learning verification. This tests the most critical untested path (716 lines) and validates learning actually happens through the hook system. + +2. **Test `brain.status()` and `brain.get_stale_memories()`** — These power the health check and task management features. 8-10 focused unit tests. + +3. **Test MCP server task management tools** — 5 tests for `create_task`, `update_task`, `list_tasks`, `stale_memories`, `stats`. Simple pass-through verification. + +4. **Fix session prime boost** — Raise `_SESSION_PRIME_BOOST` from 0.05 to 0.12 so primed atoms exceed `min_activation=0.1` and actually propagate. + +### Tier 2 — Good ROI + +5. **Test embedding error paths** — 7 mock-based tests for ConnectionError, ResponseError, batch mismatches. Guards against silent failures. + +6. **Test pre-tool antipattern warning path** — The safety-critical path that warns before Bash execution is completely untested. + +7. **Test pre-compact Hebbian checkpoint** — Validates that mid-session learning persists. + +8. **Verify decay_factor is applied correctly per depth** — Add a test that confirms depth-2 activation is lower than depth-1 for the same synapse strength. + +### Tier 3 — Completeness + +9. **Add synapse type weight coherence test** — Verify all `RELATIONSHIP_TYPES` have explicit `SynapseTypeWeights` entries. + +10. **Test `ollama_manager.py` with mocks** — Basic health check, model pull, auto-start tests. + +11. **Test `backfill_transcripts()`** — Important for onboarding, currently 0% covered. + +12. **Create `encoded-with` synapses during session** — Implement the context binding mechanism.

Error messages like "permission denied" have no explicit severity keywords, leaving severity=None and making the antipattern less likely to influence the LLM's behavior on recall. New _infer_error_severity() maps error signatures to severity: - permission denied, access denied, rm -rf, DROP TABLE → "high" - Python tracebacks, command not found, module not found → "medium" - Generic errors → "medium" (safe default) Both _hook_post_tool and _hook_post_tool_failure now pass this severity to brain.remember() for antipattern atoms. The brain's remember() still calls extract_antipattern_fields() as a fallback when severity=None, so explicit values from _infer_error_severity take precedence. 16 new tests prove the pipeline end-to-end. https://claude.ai/code/session_01DG8xJRDX8tCzoRbZBKicsg --- src/memories/cli.py | 32 +++ tests/test_coverage_antipattern_pipeline.py | 243 ++++++++++++++++++++ 2 files changed, 275 insertions(+) create mode 100644 tests/test_coverage_antipattern_pipeline.py diff --git a/src/memories/cli.py b/src/memories/cli.py index 5ea6ae0..bf89c1a 100644 --- a/src/memories/cli.py +++ b/src/memories/cli.py @@ -577,11 +577,17 @@ async def _hook_post_tool(data: dict[str, Any]) -> str: # Calculate importance based on type and content importance = _calculate_importance(atom_type, content_summary, tool_name) + # For antipatterns, provide a default severity from the error + # signature so the atom is useful even when heuristic extraction + # in extract_antipattern_fields() finds no explicit keywords. + severity = _infer_error_severity(content_summary) if atom_type == "antipattern" else None + remember_result = await brain.remember( content=content_summary[:800], type=atom_type, source_project=project, importance=importance, + severity=severity, ) new_atom_id = remember_result.get("atom_id") @@ -791,6 +797,30 @@ def _infer_atom_type( return "fact" +def _infer_error_severity(content: str) -> str: + """Infer a default severity from error content when type is antipattern. + + Assigns severity based on the error signature so auto-captured tool failures + get meaningful severity even when ``extract_antipattern_fields`` heuristics + find no explicit keyword.
