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.

timwukp Bundle Sprint PlanningFacilitates sprint planning with security debt baked in: capacity planning from rolling velocity, risk-weighted prioritization balancing feature value against security debt, commitment sizing, and a DevSecOps definition of done.

lttr Bundle Docs CheckerAudit context files (CLAUDE.md, .claude/ tree, READMEs, docs) for broken references and verifiably stale content.

tomeraberbach Skill AuditAudit something against a standard, check every item in scope, and report the findings and the coverage behind them.
-
stefaniuk Bundle SemgrepRuns a Semgrep security scan over a codebase: detects languages, selects rulesets, presents the plan for explicit approval, then runs every approved ruleset through scripts/run-scans.sh, which batches the semgrep processes and writes scans.json, and merges the output to SARIF. Supports two scan modes, "run all" for full ruleset coverage and "important only" for security findings at medium-to-high confidence and impact. Uses Semgrep Pro for cross-file taint analysis when it is available. Use when asked to scan code for vulnerabilities, run a security audit with Semgrep, find bugs, or perform static analysis. For the same scan without the approval gate, use the /static-analysis:semgrep-scan workflow.

davidme6-self-learning-skill Bundle API GatewayConnect to 100+ APIs (Google Workspace, Microsoft 365, GitHub, Notion, Slack, Airtable, HubSpot, etc.) with managed OAuth. Use this skill when users want to interact with external services. Security: The MATON_API_KEY authenticates with Maton.ai but grants NO access to third-party services by itself. Each service requires explicit OAuth authorization by the user through Maton's connect flow. Access is strictly scoped to connections the user has authorized. Provided by Maton (https://maton.ai).
