Conciseness

The body is lean and assumes Claude's competence: it gives exact config paths, exact field values, and a one-line distinction ('a decision is a choice with rationale and consequences, not a casual preference') with no padding and no explanation of concepts Claude already knows.

Actionability

Concrete, executable guidance is present throughout — exact paths (~/.codex/basic-memory.json), exact fields (type: decision, status: open, decided: <ISO timestamp>), and precise placement rules — but there is no example note body and no exact write command, leaving minor gaps.

Workflow Clarity

A clear five-step numbered sequence ends with a confirmation step ('Confirm with the permalink') that acts as a checkpoint, and the supersedes/link handling provides a feedback path; this is not a destructive or batch operation so no cap applies, though there is no explicit validation that the write persisted beyond the permalink check.

Progressive Disclosure

For a single-purpose skill well under 50 lines with no need for external reference files, the body is cleanly organized into an intro plus a numbered Steps section with sub-bullets, and it cleanly delegates detail to the bm-writing skill rather than nesting references.

Specificity

Names the domain ('Capture a durable engineering decision in Basic Memory') and lists several concrete content elements (rationale, alternatives, consequences, affected work), but 'capture' is a single verb and the listed items are captured fields rather than distinct actions, leaving minor coverage gaps versus a multi-action example.

Completeness

The 'what' is clearly stated (capture a decision with these fields), but there is no explicit 'Use when...' clause or equivalent trigger guidance, so per the rubric guideline completeness is capped at 3 with the 'when' only weakly implied.

Trigger Term Quality

Domain-accurate terms ('decision', 'Basic Memory', 'rationale', 'alternatives', 'consequences') are present but lean toward specialist vocabulary rather than the natural phrases a user would say ('record a decision', 'log a decision'), and common variations or synonyms are missing.

Distinctiveness Conflict Risk

The 'durable engineering decision in Basic Memory' framing carves a narrow, distinct niche with low conflict risk against generic note skills, though the absence of explicit trigger phrasing leaves minor overlap risk with related note/recording skills rather than fully sealing it.
