How to go from idea to tested feature with /spec, /plan and /build with Agent Skills

Install the skills and run a feature through spec, plan and incremental build with tests at every step.

Short answer: Run npx skills add addyosmani/agent-skills to install all 25 skills into your agent; then run /spec and describe what to build; the spec comes before any code; run /plan to break it into small, atomic tasks. All steps.

Who it is forA developer who wants an agent to build features in small, tested slices instead of one giant change.

The problemAgents jump straight to code, skip the spec and produce large changes that are hard to verify.

The outcomeA written spec, a plan of small atomic tasks and code built one slice at a time, each test-driven and committed.

What you need first

  • Node.js for `npx skills`, or Claude Code, Codex, Gemini CLI or Antigravity for their native installs
  • Git
  • SSH keys for the Claude Code marketplace, or the HTTPS URL workaround in the README

Steps

  1. Run npx skills add addyosmani/agent-skills to install all 25 skills into your agent
  2. Run /spec and describe what to build; the spec comes before any code
  3. Run /plan to break it into small, atomic tasks
  4. Run /build to implement one slice at a time, or /build auto to implement every task after one plan approval
  5. Run /test to prove it works before you merge

Prompt for your agent

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.

Caveat. /build auto still pauses on failures or risky steps; it removes the stepping between tasks, not the verification.
