Conciseness

Every line is repo-specific, non-inferable knowledge: exact commands, file paths, function names, and gotchas ("init_db.sql uses id as PK for sessions, not session_id"). There is no explanation of concepts Claude already knows, and the dense bullet style matches the 'lean and efficient; every token earns its place' anchor. Not 4 because no section could be trimmed without losing non-obvious information.

Actionability

Commands are copy-paste ready ("pytest tests/ -q --basetemp .pytest_tmp", "python3 -m py_compile daemon/main.py cli/mcp_adapter.py"), and the testing patterns give exact idioms with real identifiers ("MagicMock(spec=Dependencies)", "app.dependency_overrides[get_dependencies] = lambda: deps", "asyncio.run(handler(req, deps=deps, _auth=None))"). This matches the fully-executable anchor with specific examples covering the common cases; no gaps found, so it does not fall to 4.

Workflow Clarity

The Commands section sequences quick syntax check → full suite → targeted run, and includes a result-interpretation checkpoint ("'passed + skipped' = green" with expected ~7 skips), matching 'clear sequence with most checkpoints present'. Not 5 because the edit→verify loop is implicit rather than an explicit validate-and-recover workflow (no 'if tests fail, do X' guidance); not 3 because validation checkpoints are present, not absent, and no destructive/batch cap applies.

Progressive Disclosure

The single SKILL.md is well organized into Commands / Architecture conventions / Gotchas / Testing patterns with no nested references at all (no references/, scripts/, or assets/ bundle exists), matching 'good structure; most content appropriately placed'. Not 5 because at ~70 body lines it exceeds the under-50-line simple-skill exception, and the detailed Testing patterns section is the one candidate that could split into a reference file; not 3 because there is no misplaced inline bulk and navigation is easy.

Specificity

The description lists several concrete content categories — "Commands, architecture conventions, known gotchas, and testing patterns" — and pins them to a specific stack ("FastAPI + Click + Postgres/Weaviate, pytest with mocked heavy deps"), matching the anchor for several specific actions with minor gaps. It falls short of 5 because it describes what the skill contains rather than enumerating the concrete actions it enables (e.g., running tests, navigating the DI container), and short of 3 because the 'what' is far more detailed than 1-2 generic actions.

Completeness

The 'what' is clear and detailed (commands, conventions, gotchas, testing patterns), but there is no 'Use when...' clause or equivalent explicit trigger guidance — the 'when' is only weakly implied by "for working in the vault-memory Python daemon repository", which the rubric explicitly caps at 3. Not 4 because the cap rule takes precedence over the weak implication; not 2 because the 'what' half is fully present.

Trigger Term Quality

Strong natural keywords a developer in this repo would say: "vault-memory", "Python daemon repository", "FastAPI", "Click", "Postgres/Weaviate", "pytest" — good coverage per the anchor. Not 5 because a few natural synonyms are missing ("Obsidian", "vault", "CLI", " Lite Mode"); not 3 because the terms go beyond merely 'some relevant keywords' and include the stack names users actually mention.

Distinctiveness Conflict Risk

It names a specific repository and a distinctive stack (vault-memory, FastAPI + Click + Postgres/Weaviate), giving it a clear niche with minimal overlap risk against other skills. It clearly matches the 5 anchor (clear niche with distinct triggers) and does not fall to 4, since no closely related generic skill would plausibly collide with these triggers.
