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.
-
knowledgeislands Bundle Ki Housekeeping ClaudeGoverns accumulated Claude state from Desktop, Cowork, Claude Code (`~/.claude/`), and VSCode chat: sessions, artifacts, backups, plugins, project cache, and selected native auto-memory. It guides repository-scoped Claude Code session acquisition and later housekeeping: discover, list, faithful read, checkpoint, staging, harvest, and safe cleanup. Triggers: "acquire Claude Code sessions", "import Claude sessions", "audit Claude memory", "Claude memory hygiene", "clean up Claude storage", "obsolete Cowork sessions", "Claude housekeeping audit", "check ~/.claude". It is not a Knowledge Islands base memory cascade (`ki-repo-kb`) or context cost (`ki-tokenomics`).
-
knowledgeislands Bundle Ki Subagents ClaudeAudit and write the Claude Code Markdown/YAML projection of a portable KI subagent. Use after `ki-subagents` establishes the runtime-neutral role, selection, instructions, lane, grounding, hand-offs, and orchestration intent. Carries source-shape checks for YAML, required Claude fields, and Claude-specific configuration. It does not prove installed, selected, activated, or executed Claude agents. For Codex TOML use `ki-subagents-codex`; for portable semantics use `ki-subagents`.
-
knowledgeislands Bundle Ki Repo Homebrew TapCodify, audit, and scaffold the Knowledge Islands Homebrew tap — the `homebrew-<x>` distribution repo that holds `Formula/*.rb` for Knowledge Islands command-line tools. This skill WRAPS Homebrew's external standard (the Formula Cookbook + `brew audit`/`brew style`) rather than inventing a house one: it checks the tap's shape (a `Formula/` dir, one formula per tool, the README formulae table, a versioned-tarball source) and reports the explicit `brew` checks required for formula correctness. Use when auditing the tap, adding a formula, scaffolding a new tap, or refreshing against Homebrew's rules. Triggers: "audit the homebrew tap", "add a formula", "does the tap follow Homebrew's standard", "scaffold a homebrew tap", "is this formula valid", "refresh the homebrew-tap standard". Governs the tap **container** — the repo shape and the formula shape — not the tools themselves (for a `tools-*` CLI repo use `ki-repo-tools`) nor the repo's GitHub settings and standard files (for those use `ki-repo`).
-
knowledgeislands Bundle Ki Work HousekeepingGoverns recurring repository housekeeping templates: their placement, identity, cadence, last-run evidence, and safe due-run spawning through ki-next. Use for "add recurring maintenance", "define housekeeping", "audit housekeeping", or "create a monthly repository check". In a non-KB repository templates live in docs/housekeeping; in a Knowledge Base they live in Streams/Housekeeping. It does not perform runtime-specific state cleanup, which is ki-housekeeping-claude.
-
tbc-servicos Bundle Code ReviewPerform comprehensive AdvPL/TLPP code review covering SonarQube rules, Protheus.doc documentation, security, performance, clean code, and TOTVS Protheus framework best practices. Use when a user says "review this code", "code review", "check this source", "audit this AdvPL/TLPP", or needs a structured quality assessment of .prw/.tlpp/.prx files.
-
aks-builds Bundle Bdd Anti PatternsWhen the user wants to audit, refactor, or rescue a Cucumber / Gherkin / SpecFlow / Reqnroll / behave BDD suite from common failure modes. Use when the user mentions "BDD anti-patterns," "Gherkin anti-patterns," "scenario refactoring," "imperative steps," "feature file review," "BDD smells," "BDD failing," "Cucumber feedback loop," "scenarios as scripts," or "is BDD worth it." For Cucumber/Gherkin basics see cucumber-gherkin. For .NET BDD see specflow-reqnroll. For Python BDD see behave.
-
aks-builds Bundle Test Data ManagementWhen the user wants to design or audit how test data is generated, managed, masked, and reset between tests. Use when the user mentions "test data," "test data management," "TDM," "fixtures," "factories," "FactoryBot," "factory_bot," "Bogus," "faker," "synthetic data," "data masking," "PII scrubbing," "production snapshot," "test database seeding," "anonymization," or "transactional rollback in tests." For environments see test-environment-management. For pact tests see pact-contract-testing. For flaky tests caused by data leakage see flaky-test-management.
-
aks-builds Bundle Test Environment ManagementWhen the user wants to design or audit where tests run — local dev, CI runners, ephemeral preview environments, shared staging, prod-shadow, or production canaries. Use when the user mentions "test environment," "test envs," "preview environments," "ephemeral environments," "staging," "PR environments," "review apps," "dev environment," "Vercel previews," "Render preview," "Heroku review apps," or "where should tests run." For local in-process containers see testcontainers. For data scope see test-data-management. For overall strategy see test-strategy.

anton-abyzov Skill HandoffHand off your in-flight work to ANY other AI coding tool so you can continue exactly where you left off — works in 8+ tools (Claude Code, Codex, OpenCode, Gemini, Antigravity, Cursor, Aider, Cline/Roo, Windsurf). Writes one portable, secret-scrubbed handoff document plus a full diff of your uncommitted edits, then prints the absolute path, a clickable link, and a copy-paste resume prompt. Use this skill whenever the user is running out of subscription tokens, wants to switch tools mid-task, says 'handoff', 'continue elsewhere', 'continue on another machine', 'switch to Codex/OpenCode/Gemini/Cursor', or 'I'm out of tokens'. Self-contained: needs only git and a shell; uses 'specweave handoff' as an optional accelerator if it is on PATH.
-
matejformanek Skill Row Level SecurityPostgreSQL's Row-Level Security (RLS) — `CREATE POLICY` / `ALTER TABLE ... ENABLE ROW LEVEL SECURITY` / policy application in the rewriter — plus the related security-barrier machinery + leakproof qualification checks. Loads when the user asks about RLS policy semantics (USING vs WITH CHECK, PERMISSIVE vs RESTRICTIVE), how policies are applied to a query at rewrite time, why a qual can/cannot be pushed below a security barrier, the leakproof function attribute, ROLE mapping for BYPASSRLS / NOFORCERLS, `row_security` GUC, or debugging why an RLS policy is/isn't firing. Also covers security-barrier views (`WITH (security_barrier = true)`), which use the same qual-pushdown-prohibition machinery. Skip when the ask is about pg_hba.conf-level authentication, GRANT/REVOKE table-level privileges, SELinux (`sepgsql`), or database-level security features unrelated to per-row visibility.

-
korchasa Bundle SaveUse when the user provides a source (URL, file path, or free text) to save into the project's memex — a long-term knowledge bank for AI agents.

cody-hutson Bundle Skill Compliance AuditorMeasures skill trigger-compliance — whether the RIGHT skill actually fires for the requests it should serve — across the pmo-platform skill catalog, closing the coverage gap upstream of output-quality and structural audits. It runs template-seeded scenarios at three strictness levels (explicit / neutral / competing), classifies each tool-call trace deterministic-first, and reports a per-strictness compliance rate. Single Measure mode, plus a read-only re-render variant. A mandatory cost governor makes every run operator-gated, scenario-capped, and --dry-run-first. Distinct from eval-writer (which authors eval suites), pmo-qa-auditor (which grades output quality), and gate-evaluation-spec (which measures gate-decision judgment). Triggers: "measure skill trigger-rate", "audit skill compliance", "does the right skill fire", "is this skill's description drifting", "run the trigger-compliance pass", "check skill firing rate", "skill compliance report".

cody-hutson Bundle Pmo Knowledge ManagerKnowledge Manager Specialist — captures, structures, routes, and stewards project knowledge assets (lessons learned, runbooks, decision records, reference docs) so they land in their governed home, not as two disconnected generate-then-route steps. Composes artifact-generator (produces/stages the asset) + file-router (classifies + routes it to its governed home) — invokes them via the core/ registry skill-chain, never re-implements them (ADR-019). Modes: Capture · Structure/Steward · Route/File · Knowledge-Gap Audit. Use when you want the platform to act as the Knowledge Manager. Triggers: "act as knowledge manager", "capture this as a knowledge asset", "steward the knowledge base", "file this lesson learned", "build the runbook and file it", "where does this knowledge go", "what knowledge are we missing".
-
