Conciseness

The body is lean and field explanations are tool-specific knowledge Claude would not already have (defect_profile, bug_magnet, co_change_partners), so they earn their tokens. A few rationale sentences could be trimmed — 'This prevents accidentally violating architectural decisions' and 'the strongest single signal that the next edit breaks something; lead with it' explain motivation rather than instruct — matching anchor 4's 'minor instances of over-explanation'. Not 5 because of those trimmable sentences; not 3 because there is no padded or generic explanation of concepts Claude already knows.

Actionability

Every tool invocation is given as copy-paste-ready literal syntax — get_risk(targets=["path/to/file.py"]), the batched multi-file and directory example, get_context(targets=["file.py"]), and get_health(targets=["file.py"]) — covering the common cases (single edit, multi-file edit, refactor/move). Return fields, exact warning thresholds (90th percentile, >10 dependents, bus factor 1), and a tool-error fallback are all specified, matching anchor 5.

Workflow Clarity

The workflow is clearly sequenced by scenario (before editing → batch case → warning criteria → refactor/move path → error handling), the 'When to warn the user' section is an explicit threshold checklist, and the Error handling section provides a feedback loop for tool failures ('proceed with the modification but note that risk assessment was unavailable'). This matches anchor 5's 'explicit validation steps; feedback loops for error recovery; checklists'. Not 4: no checkpoint is missing within the skill's pre-modification scope — what happens after the warning is the user's decision, outside this skill's remit.

Progressive Disclosure

The skill is under 50 lines with no bundle files present (references/, scripts/, assets/ do not exist), and no external references are needed; per the rubric's simple-skill guideline, well-organized sections alone earn the top score. Headers cleanly separate each scenario, and no content that belongs in a separate file is inlined.

Specificity

The description names a specific domain ('Repowise-indexed repository') and concrete trigger actions ('modifying, refactoring, moving, or deleting files'), but it never states what the skill itself does — the capability (e.g., assessing change risk, calling get_risk) is only implied by the skill name. Per the guideline to score only what is explicitly stated, this matches anchor 3: domain named with some concrete actions but not comprehensive capability coverage. Not 4 because the skill's own actions are entirely unstated; not 2 because the domain and trigger actions are specific, not generic.

Completeness

The 'when' is explicit and detailed ('Use before modifying, refactoring, moving, or deleting files...'), but the 'what' — what the skill actually does when invoked — is never stated in the description itself. This sits between anchor 2 (only 'when' present without 'what') and anchor 3 (clear 'what', weak 'when'): the missing 'what' mirrors anchor 2's condition, but the unusually rich, explicit 'when' clause with concrete trigger phrases lifts it above anchor 2's bare 'Use when working with documents' example. Not 4 because one of the two required elements is absent, not 2 because the trigger guidance is far stronger than the anchor-2 example.

Trigger Term Quality

Natural developer vocabulary is present: 'modifying, refactoring, moving, or deleting files', 'shared utilities', 'core modules', 'public APIs', plus an explicit 'Use before...' clause. A few common synonyms are missing ('updating', 'editing', 'renaming', 'changing code'), so it does not reach anchor 5's comprehensive coverage; it clearly exceeds anchor 3's 'some relevant keywords' since four change-type verbs and three file-class nouns are covered.

Distinctiveness Conflict Risk

The 'Repowise-indexed repository' qualifier creates a clear niche with distinct triggers and minimal conflict risk against generic file- or code-editing skills, matching anchor 5. Not 4: the tool-specific scoping means even closely related skills would not be wrongly triggered outside an indexed repository.
