Security
Security agent skills give AI agents disciplined security workflows: code review for vulnerabilities, secret handling, dependency audits, and hardening checklists. Every skill on SkillMD also passes its own safety review before listing, with capability flags shown on each page.
-
agnik47 Bundle Spartan AI ToolkitA production-grade engineering quality gate that performs architecture review, security validation, performance analysis, testing verification, and release readiness checks before code is approved or merged.
-
mantasimb Bundle Branch Doc AuditAudit the current branch, unpushed commits, or working-tree diff against repository documentation and engineering guidance, then report misalignments before proposing or making changes. Use when a feature has been implemented and Codex should verify alignment with architecture docs, clean-code guidance, testing expectations, feature documentation, ADRs, READMEs, or other repository-defined standards before updating code or docs.
-
adelrioj Bundle Review CodebaseUse to run a whole-system adversarial audit of the current repo across three lenses at once — codebase (defects, incoherences, affordance gaps), docs (drift, structure, coverage), and process (end-to-end workflow dead ends). Dispatches three fresh Claude subagents in parallel, each writing a ranked findings report to docs/audits/, then offers an optional fix pass on CRITICAL findings. Triggers on: review codebase, audit codebase, audit this repo, adversarial audit, codebase audit, docs audit, process audit, fable audit, three reviews, full audit, whole-system review, find everything wrong.

sailingnaturali Skill Signalk RegistryUse when publishing or maintaining a SignalK plugin and you want to know its registry score. Fetches the actual published score from the registry, previews the criteria you can fix locally (screenshots, changelog, audit, plugin-CI) with what each gap costs, and triggers an on-demand re-score via the registry's rescore issue template instead of waiting for the nightly run.

-
peterbamuhigire Skill AI Slop Audit 3Use when auditing a concrete artefact for AI slop after a major iteration or before release, with evidence-backed findings, fixes, genericness score, and A/B/C/F verdict; use anti-ai-slop during production rather than for retrospective grading.
-
peterbamuhigire Bundle Skill Writing 3Use when creating or upgrading skills in this repository. Covers repository-specific frontmatter rules, progressive disclosure, reference-file strategy, validation, and the quality bar required for production-grade engineering skills.
-
peterbamuhigire Skill Skill Safety Audit 3Use when performing a read-only safety review of a new or changed skill for credential harvesting, unsafe installers, hidden mutation, excessive permissions, unknown tools, or instruction conflicts; use skill-writing for structural quality and source-verification for factual claims.

bbrysonelite-max Skill Skills Librarian 2Maintain Brent's INSTALLED skill library — audit ~/.codex/skills for integrity (name↔folder mismatches, missing SKILL.md, stray files, dead symlinks, inactive-profile leaks), reconcile it against the Git-backed codex-skills/SKILLS-INDEX.md (what's new vs stale), and regenerate that index preserving his categories. Read-only audit by default; fixes are per-item approved; it QUARANTINES cruft to the dump, never deletes. The maintenance complement to skill-miner (miner finds new skills; librarian keeps the shelf clean). Use when Brent says "skills librarian", "clean up my skills", "skills are a mess", "dedupe my skills", "update the skills index", "what skills do I have", or after building/installing skills.
