Loop: Implement, Test, Fix
Drive a small implementation to green through a bounded number of iterations. Each iteration makes one focused change, runs the relevant checks, and reacts to the result.
Loop Steps
- Implement the smallest change that moves the task toward its acceptance criteria.
- Prove the change with a focused test first; run
tdd-change for the red/green discipline.
- Run the narrowest relevant test or check command and read the result.
- If it fails, apply one focused fix and continue to the next iteration.
Max Iterations
The loop runs at most 3 iterations. When it reaches 3 iterations without meeting a stop condition, it stops unconditionally and reports the unfinished state and the outstanding work; it never raises the bound to keep going.
Stop Conditions
Stop the loop as soon as any of these holds:
- The relevant tests and checks are green.
- An iteration produces no diff.
- The same failure repeats identically across two consecutive iterations.
Approval Gate
- Get explicit human approval before any write, commit, or destructive step in each iteration.
- The loop never self-approves, never continues past the iteration bound, and never runs destructive commands on its own authority.
- Pause and surface the state whenever approval is missing.
Safety
- Do not upload source code.
- Do not read or print secrets.
- APC does not run this loop; a human or agent follows these instructions and remains in control.
