The body is lean and assumes Claude's competence — it lists checks and grep patterns without explaining what save tampering or path traversal are, and every section earns its place.

Provides concrete, copy-paste-ready guidance: per-category grep patterns, a full report template, a severity table, an exact output path, and a dependency glob list — the agent knows exactly what to search and what to produce.

A clear 7-phase sequence with explicit validation checkpoints (Phase 4 classification, Phase 6 write-after-approval, Phase 7 re-audit trigger and release-gate feedback), including a remediation feedback loop.

No bundle files exist and the skill needs none; the body is well-organized into distinct phases, categories, tables, and a template, satisfying the 'well-organized sections' criterion for reference-free skills.

Lists multiple concrete actions across five named vulnerability categories (save tampering, cheat vectors, network exploits, data exposure, input validation) plus a concrete output artifact, matching the 'lists multiple specific concrete actions' anchor.

Explicitly answers both what (audits categories and produces a prioritised remediation report) and when ('Run before any public release or multiplayer launch'), matching the clear both-what-and-when anchor.

Relevant terms like 'security vulnerabilities', 'public release', and 'multiplayer launch' are present, but common natural variations a user would say ('security review', 'cheat detection', 'is my game safe to ship') are missing.

Game-scoped security auditing with five enumerated categories is a clear niche unlikely to conflict with other skills, matching the distinct-triggers anchor.
