The body is substantive and avoids explaining concepts Claude already knows, but it is long (~180 lines) with some tightening available — the intro framing ('This is NOT a pass/fail gate — it's a deliberate reflection step that catches omissions, flags overconfidence...') is padded, and the evidence rule is restated across Core Concepts, Best Practices, and the examples. This fits 'mostly efficient but could be tightened'; it is not score 3 because not every token earns its place, and not score 1 because there is no basic-concept filler.

Provides concrete executable guidance: a 5-axis table with per-axis questions, a 4-step workflow with substeps, an inline report template structure, and two fully-worked good/weak scorecard examples that are copy-paste-ready models — matching the score-3 anchor of specific examples for an instruction skill. It is not score 2 because guidance is complete and concrete rather than pseudocode or missing key details (the inline template compensates for the broken file reference, which is scored under progressive_disclosure).

The Workflow is a clear 4-step sequence (Collect → Score each axis → Produce report → Apply improvement) with a real feedback loop in Step 4 ('if fixable in <30 seconds, fix now; if rework needed, flag it') and a self-check checkpoint ('Would the user agree with this assessment?'), matching the score-3 anchor of explicit validation/feedback steps. This is a meta-cognitive skill, not a destructive/batch operation, so the strict feedback-loop cap does not apply; it is not score 2 because checkpoints are explicit rather than implicit.

The body is well-sectioned and references hook-integration.md (a real one-level-deep file), but it points to templates/evaluation-report.md which does not exist (a navigation dead-end) and never references the two other bundle files present (references/evaluation-criteria.md, scripts/evaluate.py), fitting 'some structure but references not clearly signaled'. It is not score 3 because of the broken path and unreferenced bundle files, and not score 1 because references are one level deep with no nesting.

Lists multiple concrete actions — 'self-rates its output on 5 axes', 'concrete evidence per criterion', 'Produces a structured 1-5 scorecard with specific improvement suggestions' — matching the score-3 anchor of multiple specific concrete actions; it is not score 2 because the actions are enumerated and comprehensive rather than partial. The imperative 'Use after completing' mirrors the accepted 'Use when...' form in the good examples, so no second-person penalty applies.

Explicitly answers both: WHAT ('self-rates its output on 5 axes... Produces a structured 1-5 scorecard') and WHEN ('Use after completing any non-trivial task'), matching the score-3 anchor with an explicit trigger clause. The 'Use after completing...' clause is an explicit trigger, so it is not capped at 2 per the missing-trigger guideline.

The trigger 'Use after completing any non-trivial task' gives an activation context, but the description lacks the natural user-facing phrases ('rate yourself', 'how good was that', 'evaluate your work') that appear only in the body, so it has some relevant keywords but misses common variations. It is not score 3 because users would not naturally utter 'self-rates its output on 5 axes' to invoke the skill, and not score 1 because 'non-trivial task' and 'scorecard' are recognizable.

The function (5-axis self-rating scorecard) is a fairly distinct niche, but the trigger 'after completing any non-trivial task' is broad enough to overlap with related review/verification skills (agent-eval, verification-loop are named in the body), fitting 'somewhat specific but could still overlap'. It is not score 3 because the activation condition is generic, and not score 1 because the scorecard function is clearly bounded.
