Plan Implementation

Overview

Execute approved plans with discipline. Each step follows a read-modify-verify loop. Phase checkpoints require human approval. Failures trigger investigation before proceeding.

When to Use

• After a plan has been approved via the planning phase
• 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 / APPROVE_WITH_NITS / 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
