Conciseness

The body is efficient and assumes competence — no padding or explanation of known concepts; every section carries substance ('TSV because GitHub renders it as a sortable table', 'Evidence is a pointer, not prose'). Minor trim opportunities (the four-row illustration table, some restated distinctions) keep it at anchor 4 rather than 5's every-token-earns-its-place, and it is clearly above anchor 3's unnecessary explanations.

Actionability

Fully executable guidance: the exact helper invocation `bash "${CLAUDE_SKILL_DIR}/scripts/log.sh" <logfile> <phase> <decision> <why> <evidence> <result>`, concrete column definitions, a complete example table, exact file locations (`decisions.tsv`, `.audit/<task-slug>.tsv`), the transcript path pattern, and `column -s$'\t' -t decisions.tsv` for terminal rendering. Matches anchor 5's copy-paste-ready coverage of common cases.

Workflow Clarity

The lifecycle is clearly sequenced (start from template, log decision points, choose local vs committed, end-of-run audit, cross-model review, Attention section) with explicit validation checkpoints: the audit checklist ('Every row maps to a real action', 'Each row's evidence resolves'), the fix loop ('Fix the log, not the story'), and a mandated pre-handback subagent review. This matches anchor 5's explicit validation, feedback loops, and checklist; anchor 4 would require a missing checkpoint, which is not the case.

Progressive Disclosure

Well-signaled, one-level-deep references that both exist in the bundle: `references/decision-log-template.tsv` (verified header-only template) and `scripts/log.sh` (verified to implement the documented behavior — header on first use, tab/newline stripping, formula-injection prefixing). Column definitions and the example are appropriately inline, matching anchor 5's clear overview with appropriately split content.

Specificity

Concrete artifact details ('a TSV log with one row per decision (what, why, evidence, result)', 'Local by default; commit it when a reviewer needs the trail') name several specific actions, but coverage gaps (no mention of auditing or reviewing the trail) keep it below the comprehensive anchor 5, and well above anchor 3's 1-2 actions.

Completeness

Explicitly answers both what ('Keep a reviewable decision trail... a TSV log with one row per decision') and when ('Use for /show-me-your-work, autonomous or multi-phase runs, or work a human reviews after stepping away') with concrete trigger phrases, matching anchor 5; it is clearly not anchor 4 since the when-clause is explicit and specific.

Trigger Term Quality

Good natural trigger coverage ('autonomous or multi-phase runs', 'work a human reviews after stepping away', '/show-me-your-work') that users would plausibly say, but common synonyms like 'audit log', 'paper trail', or 'background work' are missing, matching anchor 4 rather than 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

A distinct niche (decision-trail logging for unattended/autonomous work) with specific triggers, but 'long-running work' is somewhat broad and could overlap with generic logging or note-taking skills, fitting anchor 4 better than anchor 5's minimal-conflict profile.
