Phase
Execute an implementation phase from ready to verified. The AI drives through Ready, Implement, and Verify.
the steps, as stored
- 01Readyagent: developer
Read this phase's specification from the parent plan — typically a file under the plan's docs directory describing scope, approach, and verification for this phase.
Confirm: - Scope is clear (what to deliver and what to exclude) - Approach is actionable (you know what to build) - Verification criteria exist (you know how to prove it works) - Any dependencies from earlier phases are met
If anything is unclear or a dependency is unmet, raise it now before starting implementation.
- 02Implementagent: developer
Execute the work described in the phase specification. Keep changes focused on this phase's scope — do not scope-creep into adjacent work.
Run tests after each significant change to catch regressions early.
- 03Verifyapproval gateagent: reviewer
Run the verification defined in the phase specification. Report what you checked, what passed, and what failed.
If anything fails, reject to loop back to implement. Do not patch issues inline — the developer fixes, then verification re-runs from scratch.
Request operator approval before advancing.
- 04Completecontext gate
Phase complete. The parent plan's execute-phases step will detect this and advance to the next phase automatically.
use it for
- Implement phase 3 of an auth refactor with verification before close
- Execute a migration-testing phase from ready state to verified
- Run one chunk of a larger plan end to end with quality gates
without it, with it
| without | with phase |
|---|---|
| A phase is called done the moment the code compiles, with no real check | The AI drives through Implement, then pauses at an approval step before the phase is marked complete |
| There is no trace of what was built in this phase or whether it was verified | Every step — Ready, Implement, Verify — is logged automatically, so the audit trail is already there |
| Each phase is executed differently depending on who picks it up | The AI drives the same four-step phase process every time, with verification before completion |
