Conciseness

Every section conveys bm-specific knowledge Claude cannot already have — severity semantics ("error | Will not go away without a fix"), background indexing behavior, cloud-project limitations, exit codes — with no padding or explanation of known concepts. This matches the 5 anchor: lean, assumes competence, every token earns its place.

Actionability

Commands are copy-paste ready ("bm doctor --skip-self-test --json", "--project NAME"), the report's stable JSON shape is shown in full for parsing, and the severity table maps each level to a concrete action ("Offer the `command`; if it is null, explain the evidence"). This fully matches the 5 anchor.

Workflow Clarity

The Fix section is a clearly sequenced four-step process — summarize findings, show commands and ask before running, run approved commands, then "Run bm doctor ... again and confirm the findings are gone" — with an explicit user-consent checkpoint and a final validation step. Not 5 because there is no explicit error-recovery branch for what to do when findings persist after the fix, which the 5 anchor expects as a feedback loop.

Progressive Disclosure

The body is a single well-organized file with clear sections (When to Use, Run It, Read the Report, Fix, Exit Codes), no bundle files exist, and no content clearly belongs in a separate reference. Not 5 because the ~88-line body exceeds the under-50-line simple-skill exception, and the 20-line report JSON example is the kind of detail that could live in a reference file if the skill grew.

Specificity

The description lists three concrete actions covering the skill's full workflow — "Check local Basic Memory projects with bm doctor", "explain the findings", and "run the suggested fixes once the user agrees" — with no coverage gaps within the skill's scope. It fits the 5 anchor (multiple specific concrete actions, comprehensive) better than 4, which would require minor gaps.

Completeness

Both questions are explicitly answered: the "what" is the three named actions, and the "when" is an explicit "Use when" clause with three concrete trigger symptoms. This matches the 5 anchor's pattern of a clear what plus explicit trigger phrases.

Trigger Term Quality

"Use when search misses or repeats notes, or a save looks lost" uses natural symptom phrases a user would actually say, plus the distinctive terms "bm doctor" and "Basic Memory". Not 5 because common synonyms are missing (e.g., "duplicate note", "can't find a note", "index out of sync"); not 3 because the natural phrasing present goes beyond bare domain keywords.

Distinctiveness Conflict Risk

"Check local Basic Memory projects with bm doctor" carves out a clear niche with a named tool, so conflict risk is low. Not 5 because the trigger clause alone ("a save looks lost", "search misses") could fire on generic save/search complaints unrelated to Basic Memory — minor overlap risk matching the 4 anchor.
