# Executing Plans ## Per-task loop 1. Read the current plan item and its acceptance signal. 2. Claim only one task at a time. 3. Execute using TDD where code changes are required. 4. Update evidence: commands, files changed, decisions, and blockers. 5. Mark complete only when the stated acceptance signal passes. If reality diverges from the plan, stop and update the plan rather than silently improvising.
