 "title": "Go from idea to tested feature with /spec, /plan and /build",
 "page_title": "How to go from idea to tested feature with /spec, /plan and /build with Agent Skills",
 "summary": "Install the skills and run a feature through spec, plan and incremental build with tests at every step.",
 "who": "A developer who wants an agent to build features in small, tested slices instead of one giant change.",
 "problem": "Agents jump straight to code, skip the spec and produce large changes that are hard to verify.",
 "outcome": "A written spec, a plan of small atomic tasks and code built one slice at a time, each test-driven and committed.",
 "steps": [
  "Run `npx skills add addyosmani/agent-skills` to install all 25 skills into your agent",
  "Run `/spec` and describe what to build; the spec comes before any code",
  "Run `/plan` to break it into small, atomic tasks",
  "Run `/build` to implement one slice at a time, or `/build auto` to implement every task after one plan approval",
  "Run `/test` to prove it works before you merge"
 ],
 "agent_prompt": "Using addyosmani/agent-skills, run /spec for <feature>, then /plan, and show me the plan. After I approve, implement it with /build one slice at a time, test-driven, committing each task, and stop on any failing test.",
 "agents": [

 "difficulty": "Intermediate",
 "time": "1 hour",
 "basis": "readme",
 "caveat": "/build auto still pauses on failures or risky steps; it removes the stepping between tasks, not the verification.",
