Conciseness

The workflow, template, and index sections are project-specific and earn their tokens, but 'What Makes a Good ADR', the 'Categories of Decisions' table, and 'ADR Lifecycle' largely restate the standard Nygard ADR practice Claude already knows. This is 'mostly efficient but includes some unnecessary explanation' rather than the minor-trimming case at 4.

Actionability

The skill provides a complete copy-paste ADR template, exact file paths and naming scheme ('docs/adr/NNNN-decision-title.md'), a concrete index format, and literal fallback responses ('No ADRs found in this project. Would you like to start recording architectural decisions?'). As an instruction-only skill, its guidance is fully executable.

Workflow Clarity

Both workflows are numbered with explicit validation checkpoints: 'Do not create files without explicit consent', 'present the draft ADR to the user for review. Only write... after explicit approval. If the user declines, discard the draft without writing any files.' The approval loop is exactly the right validation for a file-creating skill, and no destructive/batch cap applies.

Progressive Disclosure

A single well-organized file with clear section headers and no nested references, and every path referenced in the body is one the skill itself creates. At 173 lines, though, it exceeds the simple-skill exception, and content like the full ADR template and categories table could be split into a reference file, keeping it at 'good structure; minor organization gaps' rather than 5.

Specificity

The description lists multiple concrete actions — 'Capture architectural decisions... as structured ADRs', 'Auto-detects decision moments', 'records context, alternatives considered, and rationale', 'Maintains an ADR log' — comprehensively covering the skill's scope. All actions are explicitly stated, matching the comprehensive-coverage anchor rather than the minor-gaps anchor at 4.

Completeness

The 'what' is clear (capture decisions as structured ADRs, maintain a log), but there is no 'Use when...' clause or equivalent explicit trigger guidance, capping this dimension at 3 per the judging guidelines. It sits above the score-2 anchor because the 'what' is concrete and multi-part rather than vague.

Trigger Term Quality

Relevant keywords are present ('architectural decisions', 'ADRs', 'decision', 'rationale') but common natural phrases users would say — 'why did we choose X', 'record this decision', 'ADR this' — are absent. This matches 'some relevant keywords but missing common variations or synonyms' rather than the good coverage at 4.

Distinctiveness Conflict Risk

'Architectural decisions' and 'ADRs' carve a clear niche with low confusion risk against most skills, though overlap is possible with general documentation or memory-keeping skills. Not 5 because no explicit trigger phrases distinguish it from those near neighbors.
