Conciseness

Mostly efficient: tight tables, a fill-in matrix template, and lean 'see references/…' pointers assume Claude's competence. Not 5 because the Overview's Wikipedia quote and some framing prose are mild padding that could be trimmed; not 3 because the body is largely lean rather than noticeably verbose.

Actionability

Provides copy-paste-ready guidance: a full markdown risk-matrix template, a concrete grep command for risk tags, and a CI YAML gate. Not 5 because the CI example invokes scripts/build-risk-coverage.py, which is not present in the bundle, leaving one executable path unresolved.

Workflow Clarity

A clear Steps 1–8 sequence with explicit validation in Step 8 (orphan detection, CI fail-on-orphan-score gate). Not 5 because the validate→fix→retry loop is implicit (the gate 'fails if' but the recovery steps are not spelled out); not 3 because checkpoints are genuinely present rather than missing.

Progressive Disclosure

Overview in SKILL.md with a well-signaled one-level-deep 'Going deeper' routing table; all six referenced files exist and content is appropriately split (heavyweight methods, calibration, storming, registers, checklist all live in references/). Not 4 because navigation and file split are clean with no nesting or buried references.

Specificity

Lists multiple concrete actions ('risk matrix and risk register authoring, likelihood x impact scoring, risk storming, calibration, and risk-to-test coverage mapping') plus a structured intake spec (feature, category, impact 1-5 by likelihood 1-5, score; heatmap; mitigations with owners and due dates) — comprehensive coverage. Not 4 because coverage of concrete capabilities is thorough rather than having minor gaps.

Completeness

Explicitly answers both what (the RBT umbrella producing the per-feature/per-release matrix artifact) and when ('Use for any risk-based-testing artifact: building a matrix or register, running a risk-storming session, calibrating ratings against defects, or mapping risks onto test coverage.'). Not 4 because the 'when' clause is explicit with concrete trigger phrases rather than merely present.

Trigger Term Quality

Natural domain terms are present with synonyms ('risk matrix', 'risk register', 'risk storming', 'calibration', 'risk-based testing'/'RBT') that users would say. Not 5 because the 5-anchor expects synonyms plus file extensions/extensions coverage, which this abstract-process domain lacks, leaving a few natural variations uncaptured.

Distinctiveness Conflict Risk

Occupies a clear risk-based-testing niche with distinct triggers (matrix/register authoring, risk storming, calibration, coverage mapping) and minimal overlap with adjacent skills. Not 4 because the niche and triggers are sharply distinguished rather than having minor overlap risk.
