Install the plan-implementation skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description. 

git clone --depth 1 https://github.com/a5c-ai/babysitter.git /tmp/babysitter
mkdir -p ~/.claude/skills
cp -r /tmp/babysitter/library/methodologies/rpikit/skills/plan-implementation ~/.claude/skills/plan-implementation
available in every project

In the Claude apps, zip the folder and upload it from the Skills settings. The folder on GitHub

The instructions your agent would load

SKILL.md as published, without the frontmatter. Read it on GitHub

  • For medium and high stakes changes (low stakes can proceed inline)
  • When structured execution with verification is needed

Process

  1. Load plan - Validate plan exists and is approved
  2. Stakes enforcement - High: halt without plan. Medium: ask. Low: proceed.
  3. Worktree isolation - Offer git worktree based on stakes level
  4. Execute steps - For each: mark in-progress, locate files, read, modify, verify, mark complete
  5. Phase checkpoints - Summarize and ask: continue, review, or pause
  6. Failure handling - Stop immediately, investigate, propose fix, get approval for deviations
  7. Code review - Run code-reviewer agent (APPROVE / APPROVEWITHNITS / REQUEST_CHANGES)
  8. Security review - Run security-reviewer agent (halt if failed)
  9. Completion summary - Steps completed, files changed, test status, plan location

Key Rules

  • Follow the plan strictly; deviations require explicit approval
  • Verify before declaring done; run verification after each step
  • Track progress visibly via plan document updates
  • Read files before modifying them
  • Complete code and security reviews before finishing
