agent-skills

This is the agent-skills project — a collection of production-grade engineering skills for AI coding agents.

Project Structure

skills/       → Core skills (SKILL.md per directory)
agents/       → Reusable agent personas (code-reviewer, test-engineer, security-auditor)
hooks/        → Session lifecycle hooks
.claude/commands/ → Slash commands (/spec, /plan, /build, /test, /review, /code-simplify, /ship)
references/   → Supplementary checklists (testing, performance, security, accessibility)
docs/         → Setup guides for different tools

Skills by Phase

Define: spec-driven-development Plan: planning-and-task-breakdown Build: incremental-implementation, test-driven-development, context-engineering, source-driven-development, frontend-ui-engineering, api-and-interface-design Verify: browser-testing-with-devtools, debugging-and-error-recovery Review: code-review-and-quality, code-simplification, security-and-hardening, performance-optimization Ship: git-workflow-and-versioning, ci-cd-and-automation, deprecation-and-migration, documentation-and-adrs, shipping-and-launch

Conventions

  • Every skill lives in skills/<name>/SKILL.md
  • YAML frontmatter with name and description fields
  • Description starts with what the skill does (third person), followed by trigger conditions ("Use when...")
  • Every skill has: Overview, When to Use, Process, Common Rationalizations, Red Flags, Verification
  • References are in references/, not inside skill directories
  • Supporting files only created when content exceeds 100 lines

Commands

  • npm test — Not applicable (this is a documentation project)
  • Validate: Check that all SKILL.md files have valid YAML frontmatter with name and description

Boundaries

  • Always: Follow the skill-anatomy.md format for new skills
  • Never: Add skills that are vague advice instead of actionable processes
  • Never: Duplicate content between skills — reference other skills instead
