Conciseness

The ~45-line body is lean and assumes Claude's competence: no explanations of what refactoring or hotspots are, and every line carries Repowise-specific facts Claude cannot know (field semantics like 'fix_count over the trailing 6 months', the caveat 'the per-symbol counts are approximate — read them as "mostly here"', terse prioritization 'A file that keeps getting fixed is the strongest single signal... lead with it'). Re-checking anchor 4, no section is padded or could be trimmed without losing operational information.

Actionability

Fully executable guidance: copy-paste-ready calls ('get_risk(targets=["path/to/file.py"])', the batch form 'get_risk(targets=["file1.py", "file2.py", "module/"])', 'get_context', 'get_health') plus specific numeric decision thresholds ('above 90th percentile', 'More than 10 dependents', 'Bus factor of 1', named risk types) and a concrete fallback for tool errors. Specific examples cover the common cases (single file, batch, refactor, error).

Workflow Clarity

The workflow is sequenced by scenario (before editing → read risk signals → warn on thresholds → get_context before refactors → get_health for heavy refactors) with an explicit warning checklist as the validation gate before any modification and a clear error-recovery path ('If get_risk returns a tool error... Proceed with the modification but note that risk assessment was unavailable'). The destructive-operation cap does not apply: the skill itself is the pre-edit validation step, and the simple-skill exception (under 50 lines, single task) is satisfied.

Progressive Disclosure

The skill is under 50 lines, self-contained, with no references/, scripts/, or assets/ bundle — nothing to offload. Five well-labeled sections ('Before editing a file', 'When modifying multiple files', 'When to warn the user', 'Before refactoring or moving code', 'Error handling') organize the content, matching the rubric's exception for short single-purpose skills.

Specificity

The domain is named precisely ('a codebase that has Repowise indexed (indicated by a .repowise/ directory)' with trigger operations 'modifying, refactoring, or deleting files'), but the skill's own actions remain generic: 'Helps assess impact and avoid breaking things' never names what the assessment involves. Not 4 because it lists no concrete assessment capabilities (risk scores, dependents, ownership); not 2 because the domain and trigger operations are concrete rather than minimal.

Completeness

Both parts are explicitly present: 'when' is strong ('Use before modifying, refactoring, or deleting files... Activates when Claude is about to edit code, especially shared utilities, core modules, or files the user didn't explicitly mention') and 'what' is stated ('Helps assess impact and avoid breaking things'). Not 5 because the 'what' is a single shallow clause rather than a concrete capability list, unlike anchor 5's 'Extract text and tables from PDF files, fill forms, merge documents'; not 3 because 'when' is fully explicit, not merely implied.

Trigger Term Quality

Good natural keyword coverage: 'modifying, refactoring, or deleting files', 'about to edit code', 'shared utilities, core modules', plus the '.repowise/ directory' marker. Common variations users would say — 'changing', 'updating', 'renaming', 'impact analysis' — are absent, so it falls short of the comprehensive synonym coverage of anchor 5 but is clearly above anchor 3's 'some relevant keywords'.

Distinctiveness Conflict Risk

The description is gated on a unique environment marker — 'a codebase that has Repowise indexed (indicated by a .repowise/ directory)' — giving it a clear niche with distinct triggers and minimal conflict risk against generic editing, review, or refactoring skills. Re-checking anchor 4 ('minor overlap risk with closely related skills'): no other plausible skill targets .repowise-indexed codebases, so the fit to anchor 5 holds.
