Conciseness

The ~565-line body restates its core rules four or more times — "Only touch files modified in this task" and "refactor requires approval" each appear in Scope Constraints, the Core invariants list, the Prompt-based Integration block, and the configuration example — alongside padded sections Claude does not need to execute the skill (Metadata table, install commands, a ~110-line example Output Schema, a 12-agent compatibility list, Design Decisions, Future Considerations). This matches anchor 2 (noticeably verbose, several padded sections) rather than 3 (could merely be tightened).

Actionability

Guidance is largely executable: quantified trigger conditions ("At least 10 changed non-comment, non-whitespace lines"), per-pass checklists, verbatim approval-gate dialogue examples, a copy-paste prompt-injection block, a complete config example, and a fully specified output schema. Not 5 because the agent.on('task:complete') integration snippet is explicitly illustrative pseudocode rather than runnable code.

Workflow Clarity

The four passes are explicitly sequenced ("Four phases -- simplify, harden, document, re-verify (in that order)"), re-verification is mandatory with an error feedback loop ("If verification fails, return to implementation with the diagnostics; do not emit a successful completion"), budgets are enforced with a budget_exceeded flag, and each pass has a checklist — matching the anchor-5 example (clear sequence, explicit validation, feedback loops, checklists).

Progressive Disclosure

The one bundle reference is real, clearly signaled, and one level deep ("Agent-specific copy-paste snippets are in references/agent-context-snippets.md. Load only the snippet for your active agent"), but the main body inlines large chunks that belong in separate reference files — the ~110-line Output Schema example, Integration Notes, Configuration, and Design Decisions. This fits anchor 3 (content that should be separate is inline) rather than 4 (placement not mostly appropriate), and is above 2 because structure and reference signaling are present.

Specificity

Lists four concrete actions ("runs simplify, harden, re-verification, and micro-documentation passes") with a clear scope ("non-trivial code or high-impact configuration changes"), which is anchor-5 coverage; however, the second-person phrasing "when... you want a bounded quality and security sweep" triggers the rubric's third-person voice penalty of 1 on specificity.

Completeness

Explicitly answers both what ("runs simplify, harden, re-verification, and micro-documentation passes") and when ("Use when a task is complete in a general agent session... before signaling done"), with concrete trigger phrasing plus a routing clause to the CI variant. Matches the anchor-5 example structure exactly.

Trigger Term Quality

Good natural keyword coverage — "task is complete", "before signaling done", "quality and security sweep", "non-trivial code", "configuration changes" — but a few natural user phrasings are missing (e.g., "review my changes", "clean up the code"). Clearly above anchor 3 since coverage is solid rather than partial.

Distinctiveness Conflict Risk

Clear niche (post-completion self-review for coding agents) that is explicitly disambiguated from the CI variant ("For CI pipeline execution, use simplify-and-harden-ci"), leaving only minor overlap risk with generic code-review/simplify skills on terms like "simplify" and "harden".
