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.
-
gtrabanco Bundle Review Implementation 2Internal scope/classification engine composed by review-change (and reused by the audit skills): consumes the synthesized findings table, verifies every applicable axis is represented, and classifies each finding into a decision table (fix-now / replan-in-unit / decision-required / proposal / ignore). Findings only — never refactors.
-
dyoshikawa Skill Review Pr Lite 2Review a pull request for code quality and security issues without using subagents. Use when the user wants a lighter-weight PR review in a single skill.
-
dyoshikawa Skill Security Scan Diff 2Scan for malicious code in git diff between a tag/commit and HEAD
-
dyoshikawa Skill Review And Comments 2Review a PR for code quality and security issues, then post review comments on it. Runs review-pr followed by post-review-comments sequentially.
-
painhardcore Skill Maintain Verification Skill 2Periodic pass that keeps a project's verification skill and feature map honest: parallel source readers per feature, one live session driving every feature, at most one PR of proven corrections. Use for /maintain-verification-skill or "audit the verify skill".
-
serpro69 Bundle Review Code 3Code review of current git changes with an expert senior-engineer lens. Detects SOLID violations, security risks, and proposes actionable improvements. Use when performing code reviews.
-
serpro69 Bundle Review Code 4Code review of current git changes with an expert senior-engineer lens. Detects SOLID violations, security risks, and proposes actionable improvements. Use when performing code reviews.

serpro69 Bundle Review Architecture 3Review a written architecture artifact — an ADR (docs/adr/), a broader architecture doc, the architecture section of a design doc, or a domain-reference kit (glossary + traps pages, reviewed as one composite artifact) — against the system it claims to describe. Verifies the EXISTENCE and TOPOLOGY of declared mechanisms (structural boundaries, data ownership, NFR mechanisms, failure isolation, state consistency, evolution/versioning, domain binding) plus decision soundness, reversibility, and provenance (self-certification of reverse-engineered claims). Use after an ADR, architecture doc, domain glossary, or domain kit is written, before or during implementation. NOT for behavioral/runtime correctness (that is $kk:review-code and $kk:review-spec). Security architecture is out of scope — delegate threat modeling to the PAL secaudit tool (mcp__pal__secaudit).

serpro69 Bundle Golang Security 2A Go security skill for reviewing code
-
udecode Skill Sync Vision 2Incrementally audit kitcn doctrine drift since the recorded baseline, classify it, update VISION.md and local planning owners, then advance the baseline only after proof.
-
udecode Skill Sync Convex Auth 2Sync `zbeyens/convex-better-auth` with upstream, then sync kitcn against upstream `convex-better-auth` changes. Use when asked to run `sync-convex-auth`, compare the fork with upstream, fast-forward or PR the fork update when safe, audit commits the fork was behind on, classify relevance to kitcn auth integration, and delegate one implementation PR through `task`.
-
udecode Skill Changeset Resolve 2Repair an unreleased `.changeset/*.md` file so it matches the real branch delta against `main`. Use when a changeset was edited iteratively during debugging, when bullets may reflect turn-by-turn history instead of `main...HEAD`, when "removed/gone/renamed" claims need proof, or when you need to audit whether a changeset is actually lossless before commit.
-
ma08 Skill Personal Os Repo Cleanup 2Use when the user asks to commit, clean, audit, reconcile, push, pull, or coordinate dirty personal_os changes across the VM and Mac checkouts, especially when live task-specific sessions may own folders, orphaned artifacts need curated commits, or divergent main histories must be synchronized safely.
-
managedcode Bundle Mcaf Dotnet Codeql 2Use the open-source CodeQL ecosystem for .NET security analysis. Use when a repo needs CodeQL query packs, CLI-based analysis on open source codebases, or GitHub Action setup with explicit licensing caveats for private repositories.
-
managedcode Bundle Mcaf Security Baseline 2Apply baseline engineering security guidance: secrets handling, secure defaults, threat modelling references, and review checkpoints for auth, data flow, pipelines, and external integrations. Use when a change has security impact but does not require a full standalone AppSec engagement.
-
managedcode Bundle Mcaf Dotnet Meziantou Analyzer 2Use the open-source free `Meziantou.Analyzer` package for design, usage, security, performance, and style rules in .NET. Use when a repo wants broader analyzer coverage with a single NuGet package.
-
nesszer Skill Linear History 2View Linear issue history. Use for activity logs and audit trails.
-
duck4nh Skill Quality Gates 2Unified quality gate skill for pre-delivery checklist, security checks, testing strategy, and handover readiness.
-
alexander-danilenko Bundle Testing 2Apply these opinionated testing conventions whenever writing, reviewing, or planning tests: what earns a test and what is coverage theatre, asserting outputs rather than mock calls, the three modes (functional, performance, security), naming and isolation rules, where to mock, and reporting findings for coverage rather than self-filtering. Includes house Jest standards for NestJS unit and contract tests, TDD discipline, and test-report structure.
-
frdel Bundle Scheduled Tasks 2Create, edit, run or audit scheduled, planned and adhoc tasks; cron, timezones and reminders.
-
xi-kari Bundle Crossframe Review 2CrossFrame Review explicit-only audit skill. Use only when the user explicitly names crossframe-review, $crossframe-review, /crossframe-review, or asks to use CrossFrame Review; do not trigger implicitly for ordinary reviews, critiques, audits, grading, smoke tests, or repair tasks. Suite-directed use after an explicit crossframe-suite invocation is allowed.
-
anthony-chaudhary Skill Dos Next Up 2Snapshot the repo's phased-plan portfolio into a dispatch packet: audit candidates with `dos verify`, render who-does-what, and emit a `dos gate` verdict. Use when you need the current next-work view before dispatching agents.
