What it does for you
The same safe path for every coding task
Left alone, a coding agent skips steps and acts without warning. This workflow locks its path in a YAML file: plan, approval, coding until tests pass, fresh review, second approval and a draft pull request.
- Approve twice before any outside action
- Catch endless loops and destructive commands
- Dry-run the whole path before handing it over
What you're buying

What you get
Result · Deterministic harness for coding agents (YAML steps)
- Deliverable
- An original Archon flow (plan, approval, bounded coding until green tests, fresh review, approval, draft PR), a guardrail checker and a simulator that replays the path identically.
Illustrative example: the real result depends on your inputs.
Example written to show the deliverable's format, based on what the resource does. It is not a capture of a real run; a real demo will replace it.
