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.
-
linuxfoundation Bundle Review Pr 2Review a pull request against CDP architecture standards — fetches PR diff, verifies previous comments are addressed, validates PR metadata (title, branch, JIRA key, size), runs a code-standards enforcer against every file in `.claude/rules/` and `.claude/hooks/guard-protected-files.sh`, and drafts inline review comments with suggested fixes. NEVER auto-posts comments or submits reviews — always presents a draft in the terminal for user approval before any comment lands on the PR. Use when reviewing PRs, checking PR quality, validating code changes, or when the user says "review", "check this PR", or "audit code".
-
bozonet Skill NPM Security TriageMonthly npm audit triage for monorepos without Dependabot — bucket critical patches, open thin safe PRs, and optionally create a short Linear In Review ticket. Use when the user asks for dependency triage, npm audit, security package updates, or safe backend dependency patches.
-
shas9 Skill Issue QueueWork through a batch of pasted issues, code-review comments, bug reports, or audit findings one at a time — triaging by severity, validating each against the current code, confirming with the user before implementing, verifying, and committing in small chunks. Use this whenever the user pastes multiple issues, review comments, a QA list, or a findings dump and wants them addressed, fixed, or worked through — even if they don't say "one at a time" or name a process. Also use when the user says things like "address these review comments", "here are the bugs, fix them", "let's go through these issues", or asks to plan and fix a group of problems together.
-
soden46 Skill Security 2Review or implement application security controls using framework-agnostic engineering principles, then adapt them to the detected project stack.
-
levi0527 Skill Review ExperimentAudit robotics/RL experiment results for validity, causal claims, contracts, and whether the next GPU budget is justified. Use when reviewing logs, checkpoints, reports, or experiment plans.
-
grimoire-rs Bundle Hex Init 2Initialize or reconfigure a project for the hex swarm - audits project context (CLAUDE.md/AGENTS.md) for the knowledge the orchestrators need (how to verify, spec/plan conventions), provisions what is missing into project context, optionally seeds default templates, and bootstraps the AI-maintained swarm memory at .agents/memory/hex.md (cached pointers, orchestration preferences, perspectives of interest). Re-entrant - run again anytime to re-audit pointers or change the setup.

magerko Bundle Launch SecurityПред-запусковый аудит безопасности приложения — секреты и ключи, аутентификация и сессии, доступ к чужим данным (IDOR, RLS), инъекции и XSS, загрузка файлов, заголовки и CORS, лимиты и расходы, утечки в ответах и логах, зависимости, прод-гигиена, вебхуки и платежи. Выдаёт отчёт с приоритетами; код не правит. Только ручной запуск.
-
snausage0x45 Bundle NetcheckRun an open-source intelligence (OSINT) investigation on a single IP address or domain and return a security analyst's briefing: a risk verdict, a short technical summary, and a facts table. Weighs ownership provenance heavily — registration age, recent registrar or registrant changes, and registrar reputation. Use this whenever the user types "netcheck" followed by an IP or domain, and also whenever they ask you to "investigate", "look up", "check the reputation of", "profile", "run OSINT on", "who owns", "who is behind", or "is this safe" for any IP address, domain, hostname, or URL — even if they don't say the word "netcheck". Trigger on indicators like 8.8.8.8, 185.220.101.1, evil-domain.com, or a pasted URL. This is passive, defensive reconnaissance only.

-
elder-plinius Skill Bt6 Queue Audit 2Audit the full pull-request and issue queue of a BT6 research or support repository, classifying readiness, evidence risk, and next action without mutating tracker state.
-
hoetaek Bundle Autopilot 2Use after ready has handed off an approved launch target (launch command, inspect target, workflow policy, TaskDocument bodies), when the user wants the rest of the wt lifecycle — launch, coordinate, review, land, retrospect — to proceed automatically with automatic reviews, hard stops, and evidence. Trigger on "$autopilot", "wt autopilot", "launch target approved, run the rest automatically", or "after ready, carry it the rest of the way". Do not use before the ready handoff, for unclear or unprepared work (route to ready), or for destructive / external / credential / cost / security / privacy-sensitive actions without explicit pre-authorization.
-
majiayu000 Bundle Skill Lifeguard 2Create, audit, and harden skills so they become self-maintaining instead of cat-and-mouse. Use when designing new skills, reviewing existing ones for drift, or turning brittle workflows into reliable ones. Forces Negative Examples, Verification Checkpoints, machine-checkable Done conditions, Replay/smoke test hooks, and Drift signal detection. Do not use for one-off prompts.

-
posthog Skill Authoring CI Workflows 2Use when adding or editing a GitHub Actions workflow, composite action, or reusable workflow under `.github/` — new CI jobs, triggers, matrices, checkout/clone tuning, action pinning, GitHub App token auth, concurrency groups, `timeout-minutes`, `paths` filters, caching, or runner choice. Covers PostHog's workflow-authoring conventions and the reasons behind them: the 500-runs/10s dispatch cap, shallow vs full clone, per-SHA push concurrency, dedicated App-token rate-limit buckets, and fork-safe secrets on a public repo. Points to the linters (`bin/hogli lint:workflows`, actionlint) that enforce the mechanical rules, and to the narrower skills for production deploys, secrets, and Depot runners. Not for debugging red CI (use debugging-ci-failures) or wiring a new secret end to end (use managing-github-actions-secrets).

nonatofabio Bundle HumanizeRewrite drafts so a person appears to have written them - cut filler, force claims that commit, break the machine cadence, then run a mechanical audit for AI tells. Use whenever the user asks to humanize, de-slop, or make text sound less like AI; whenever they say a draft reads robotic, generic, corporate, or like ChatGPT wrote it; and before delivering any blog post, essay, email, README, launch note, or docs page the user will publish under their own name. Also use when the user asks for an AI-tell audit of text they already have.
-

Use when the user asks for an approver review, a detailed PR assessment, help understanding a PR, or an approval recommendation. Compare the PR's stated intent with the code, trace data and control flow, examine architecture, contracts, failure handling, lifecycle, security, operations, tests, compatibility, and rollback, then explain important implementation decisions and credible alternatives for a technical generalist.
