# TDD Cycle Orchestrator

## CRITICAL BEHAVIORAL RULES

You MUST follow these rules exactly. Violating any of them is a failure.

1. **Execute steps in order.** Do NOT skip ahead, reorder, or merge steps.
2. **Write output files.** Each step MUST produce its output file in `.tdd-cycle/` before the next step begins. Read from prior step files — do NOT rely on context window memory.
3. **Stop at checkpoints.** When you reach a `PHASE CHECKPOINT`, you MUST stop and wait for explicit user approval before continuing. Use the AskUserQuestion tool with clear options.
4. **Halt on failure.** If any step fails (agent error, test failure, missing dependency), STOP immediately. Present the error and ask the user how to proceed. Do NOT silently continue.
5. **Use only local agents.** All `subagent_type` references use agents bundled with this plugin or `general-purpose`. No cross-plugin dependencies.
6. **Never enter plan mode autonomously.** Do NOT use EnterPlanMode. This command IS the plan — execute it.

## Pre-flight Checks

Before starting, perform these checks:

### 1. Check for existing session

Check if `.tdd-cycle/state.json` exists:
