Conciseness

The body is information-dense with no known-concept padding, but the SHA-pinning rationale is repeated across Layer 3, the config-mode walkthrough, and 'Always do these', and the ownership-boundary table is restated in the wizard and intent-classification sections. That trimmable redundancy matches the 4 anchor rather than the 5 anchor's 'every token earns its place'.

Actionability

Every mode ships copy-paste-ready commands with exact flags (`zizmor --strict-collection .`, `uvx zizmor@1.29.0`, the full `--persona=auditor --min-confidence=low --collect=all --no-ignores` audit invocation, a dirty-tree guard, concrete zizmor.yml policy blocks, and the pre-commit YAML), plus precise exit-code semantics — matching the 5 anchor's fully executable, common-case-covering guidance.

Workflow Clarity

Mode dispatch, a three-layer wizard, and per-mode flows are clearly sequenced with explicit validation checkpoints and feedback loops: refuse on a dirty tree, show the diff, re-audit what remains after every fix, and 'run the audit again and report what remains'. This matches the 5 anchor's explicit validation and error-recovery structure; the 4 anchor would imply missing checkpoints.

Progressive Disclosure

References to `references/zizmor.md` are one level deep and well signaled with named target sections ('Triage decision tree', 'Repository patterns', 'CI integration', 'Worked baseline config'), and the SKILL.md/reference split is sensible — but no `references/` directory exists in the bundle, so the single referenced file is missing and navigation dead-ends. This lands on the 4 anchor ('minor organization gaps') rather than 5.

Specificity

Lists multiple concrete capabilities — auditing workflows, composite actions, Dependabot and pre-commit configs for named finding classes ('template injection, credential persistence, unpinned uses, over-broad permissions, impostor commits') plus operational coverage ('local CLI, auto-fix, zizmor.yml policy, severity-based CI gates, SARIF upload'). Third-person voice is used throughout, and no coverage gaps are evident, matching the comprehensive 5 anchor rather than the 4 anchor's 'minor gaps'.

Completeness

Explicitly answers what (two sentences of concrete capabilities and finding classes) and when ('Use when asked to…' with six quoted trigger phrases), exactly matching the 5 anchor pattern; the 4 anchor would require a weaker or less explicit 'when' clause.

Trigger Term Quality

Includes natural user phrasings ('audit my workflows', 'run zizmor', 'is this workflow safe', 'check for template injection', 'pin my actions', 'set up a zizmor CI gate') plus synonyms and file-level terms (zizmor.yml, Dependabot configs, pre-commit configs), matching the 5 anchor's comprehensive natural-term coverage.

Distinctiveness Conflict Risk

Occupies a clear niche (zizmor security auditing of GitHub Actions) and actively disambiguates adjacent tools ('Workflow syntax and shell errors → /platform-skills:github-actions (actionlint). IaC misconfig → /platform-skills:checkov…'), minimizing overlap risk with closely related skills.
