## About

# TDD Cycle Runner Skill

## Workflow
1. Receive `start_cycle` contract from main orchestrator
2. For each phase:
  - Load phase SKILL.md and asset files
  - Execute phase guidance through the loaded phase skill
  - Route every RED, GREEN, and REFACTOR verification through `tdd-test-run`
    using an explicit expected-result contract before advancing the cycle
  - Validate contract result
  - On failure, escalate to main orchestrator
3. On completion, return `cycle_complete` contract

## Decision Points
- If any phase fails, escalate immediately
- If all phases succeed, return cycle summary

## Quality Criteria
- Only minimal context passed to each phase
- All contract handoffs validated
- No direct communication with main orchestrator by phase skill executions
- Progressive disclosure enforced
- Any rollback after a failed verification is limited to the scoped files named
  in the `test_run_request` contract

## Completion Checks
- All contracts for the cycle are satisfied
- All phase outputs are validated
- Escalation path is tested
