How AEP Works
End-to-end lifecycle from task execution to reuse.
System flow
- User and AI solve a task.
- Team captures what worked as an AEP.
- AEP is stored in the repository.
- Future tasks load and apply the AEP.
- AEP is improved after each successful run.

Refine and PromoteLifecycle phases in practice
1) Execution
The agent works through a task with normal prompting and constraints.
2) Extraction
After success, you extract only reusable signal:
- key constraints
- essential workflow order
- meaningful success checks
3) Persistence
You store the AEP in paths visible to the active tooling (for example, .codex/aep/ or .cursor/aep/).
4) Reapplication
On future related tasks, the agent loads the AEP before implementation and follows its structure.
5) Refinement
You update the pack based on real outcomes, especially failures and edge cases.
Why this loop matters
The loop compounds quality over time:
- less repeated setup
- faster alignment
- fewer avoidable regressions
- better cross-session consistency
