Conciseness

Noticeably verbose with several padded or duplicated sections: the Simplify pass rules are restated nearly verbatim in 'Prompt-based Integration' and again in the 'Core invariants' list; the Refactor Stop Hook is described in full in both the Simplify and Harden passes; the 'Agent Compatibility' section name-drops a dozen agents; 'Future Considerations' is speculative; and the example output schema alone spans roughly 110 lines. The material is instructions rather than concept explanations Claude already knows, which keeps it above the lowest anchor, but the body is several times longer than the procedure requires.

Actionability

Fully executable guidance throughout: concrete checklists ('Check for SQL injection, XSS, command injection, path traversal, and template injection in any code that builds strings from external input'), explicit finding-categorization rules with approval gates, a copy-paste-ready prompt-injection block, example approval-prompt transcripts, and a complete configuration example. A precise non-trivial-diff definition (10 changed lines or listed high-impact categories) leaves no ambiguity about what to do.

Workflow Clarity

The four passes are explicitly ordered ('Four phases -- simplify, harden, document, re-verify (in that order)') with trigger conditions, scope locks, and budget limits up front, and Pass 4 is a mandatory validation step with a failure feedback loop: 'If verification fails, return to implementation with the diagnostics; do not emit a successful completion.' Error-recovery paths (budget_exceeded, skip-all refactors, not-run verification) are all addressed.

Progressive Disclosure

The single reference (references/agent-context-snippets.md) exists, is clearly signaled, and is one level deep with its own table of contents, but substantial content that belongs in separate reference files is inlined in SKILL.md: the ~110-line example output schema, the 'Design Decisions' rationale, and the agent-compatibility roster. Structure is present and sections are navigable, but the split between overview and detailed material is only partial.

Specificity

Base score 4: the description lists several concrete actions ('runs simplify, harden, re-verification, and micro-documentation passes on non-trivial code or high-impact configuration changes') with minor coverage gaps (the structured output and learning loop are unmentioned). The second-person phrase 'you want a bounded quality and security sweep' violates the third-person voice rule, applying the mandated 1-point penalty, reducing this to 3.

Completeness

Explicitly answers both what ('runs simplify, harden, re-verification, and micro-documentation passes on non-trivial code or high-impact configuration changes') and when ('Use when a task is complete... before signaling done') with concrete trigger phrases, plus a disambiguating pointer to the CI variant.

Trigger Term Quality

Good natural trigger coverage: 'Use when a task is complete', 'quality and security sweep', 'before signaling done' are phrases a user or agent would plausibly say. A few common variations are missing, such as 'code review', 'cleanup', or 'before committing'.

Distinctiveness Conflict Risk

'Post-completion self-review' carves a clear niche with distinct timing-based triggers, and the explicit CI-variant boundary aids disambiguation. Minor overlap risk remains with generic code-review and security-review skills, so it falls just short of the 'clear niche, minimal conflict' anchor.
