Implement in slices, not in bursts.
Process
- Select the smallest meaningful slice from the plan.
- Read only the files needed for that slice.
- Reuse local patterns before introducing new abstractions.
- Edit the narrowest possible surface.
- Verify immediately after the slice.
- Update progress before starting the next slice.
Implementation Rules
- Prefer precise edits over broad rewrites.
- Preserve existing design systems and conventions unless the task explicitly changes them.
- If the change becomes wider than expected, stop and re-plan.
- If there is a specialist skill for the domain, combine it with this one.

Anti-Rationalization
| Rationalization | Response |
|---|---|
| "I will clean it all up in one pass." | Large passes hide regressions. Keep the diff narrow. |
| "I already know the pattern." | Verify the local pattern before copying it in spirit. |
| "Testing can wait until the end." | Verify per slice to catch breakage early. |
