Conciseness

The 596-line body is noticeably verbose: "Rationale and Philosophy" and "Design Decisions" cover the same ground, agent-integration guidance is restated across "Agent Compatibility", "Integration Notes/Agent Integration", and "Prompt-based Integration", the refactor-approval rule is repeated in 5+ places ("refactor_requires_approval: true # ALWAYS true -- cannot be disabled"), a ~110-line sample output YAML is inlined, and the Metadata table adds no operational value.

Actionability

Concrete thresholds ("At least 10 changed non-comment, non-whitespace lines", "Maximum: 5 comments added per task", "20% max additional diff"), copy-paste refactor/security proposal templates, config YAML, and a prompt-injection block make the guidance mostly executable; not 5 because external hooks "verify-gate" and "self-improvement" are referenced without being defined.

Workflow Clarity

The four passes are explicitly sequenced ("Four phases -- simplify, harden, document, re-verify (in that order)"), each pass has a checklist, and re-verification is mandatory with a true feedback loop ("If verification fails, return to implementation with the diagnostics; do not emit a successful completion") plus explicit not-run handling.

Progressive Disclosure

The single bundle reference is clearly signaled with lean-loading guidance ("Agent-specific copy-paste snippets are in references/agent-context-snippets.md. Load only the snippet for your active agent"), but content that clearly belongs in separate files -- the full sample output schema, integration code, and config templates -- is inlined in a 596-line body.

Specificity

"runs simplify, harden, re-verification, and micro-documentation passes on non-trivial code or high-impact configuration changes" lists several specific operations on a defined target in third person; not 5 because the passes are named at a summary level rather than comprehensively describing what each does.

Completeness

It explicitly answers both: what ("Post-completion self-review for coding agents that runs simplify, harden, re-verification, and micro-documentation passes") and when ("Use when a task is complete in a general agent session and you want a bounded quality and security sweep before signaling done") with concrete trigger phrasing, matching the top anchor.

Trigger Term Quality

Natural phrases like "task is complete", "before signaling done", and "quality and security sweep" give good keyword coverage; a few natural user variations (e.g., "review your work", "clean up before finishing") are missing, so it fits anchor 4 rather than 5.

Distinctiveness Conflict Risk

The post-completion timing plus the four-pass structure carve out a clear niche with distinct triggers and CI-variant disambiguation; minor overlap risk remains with closely related general code-review and simplify skills, so it fits anchor 4 rather than 5.
