Conciseness

The body is almost entirely project-specific procedure — commands, decision tables, exact prompts, and the output template — with essentially no explanation of concepts Claude already knows. Minor trimmable instances exist: the layer scope lists appear twice (Phase 2 bullet list and again inside the Phase 5 template's '*Applies to: …*' lines), and passages like 'It always equals Last Updated: the same date, for different readers' are explanatory padding. This fits the score-4 anchor (efficient, minor over-explanation) rather than 5, where every token would earn its place.

Actionability

Guidance is copy-paste executable throughout: 'bash .claude/scripts/adr-status.sh', 'bash .claude/scripts/md-section.sh extract docs/architecture/[adr-file].md "Decision"', exact question wordings with enumerated options ('Options: Yes, write it / Show me the full draft first…'), exact failure messages, verdict lines, and a complete markdown output template. This matches the score-5 anchor (fully executable, specific examples covering the common cases).

Workflow Clarity

Six clearly sequenced phases with explicit validation checkpoints and feedback loops: the Phase 1 counts table is a checklist for every edge case ('Never write an empty manifest silently'), Phase 4 requires user approval before any write, and the verdict loop handles error recovery ('REJECT: write nothing; fix the flagged rules and show the summary again'; 'NOT ASSESSED… supply it and run the review again'), ending with explicit verdict lines. This matches the score-5 anchor including its checklist and error-recovery criteria.

Progressive Disclosure

No bundle files exist, and the body is well-structured with per-phase headers and navigation; all external references (.claude/docs/*, .claude/scripts/*, docs/engine-reference/*) are one level deep and clearly signaled. It is not a 5 because ~100 lines of the Phase 5 output template — content that could live in a references/ file — are inlined in an already ~290-line skill; it is above a 3 because the inline content is the deliverable's own format rather than misplaced reference material.

Specificity

Concrete actions are stated in third person ('Builds a short list of must-do and never-do coding rules per system from accepted ADRs', 'needs it regenerated after ADR changes') with a clear scope (per system, from Accepted ADRs). Not a 5 because coverage has minor gaps — it omits the artifact it writes (docs/architecture/control-manifest.md) and the review gate; not a 3 because it lists several specific actions rather than just 1-2 with an unspecified remainder.

Completeness

Both what and when are explicitly answered with concrete trigger phrases: what — 'Builds a short list of must-do and never-do coding rules per system from accepted ADRs'; when — 'Use when the user wants programmer rules or a cheat sheet from the ADRs, or needs it regenerated after ADR changes.' This matches the score-5 anchor (clear what + explicit 'Use when' with concrete triggers), not the score-4 anchor where the 'when' is weaker or less specific.

Trigger Term Quality

Natural user phrasings are present: 'the user wants programmer rules', 'a cheat sheet from the ADRs', 'needs it regenerated after ADR changes'. Not a 5 because common synonyms like 'coding standards', 'conventions', or "do's and don'ts" are absent; not a 3 because the included terms are exactly what a user would say, not just domain jargon.

Distinctiveness Conflict Risk

The ADR-derived control-manifest niche has distinct triggers ('from accepted ADRs', 'cheat sheet from the ADRs') that are unlikely to fire for unrelated skills. It matches the score-5 anchor (clear niche with distinct triggers, minimal conflict risk); the score-4 anchor ('minor overlap risk') understates how tightly the triggers are bound to ADR terminology.
