Codex Kernelia Implementation Planning with Write-Scope Checks
Split a feature into small verifiable tasks that capture write scope, dependencies and integration order.
中文Install in Codex
Open Kernelia in Codex with the feature scope, affected files and any independently observable completion criteria.
- Review `.agents/skills/implementation-planning/SKILL.md` and its requirements at the pinned GitHub commit.
- Create `.agents/skills/implementation-planning/` in your project and save the reviewed file as `.agents/skills/implementation-planning/SKILL.md`.
- Start Codex from that project's root, then type `$implementation-planning` and select the matching skill.
Example task
Decide whether the following two items can run in parallel.
{"taskA":"define filter state","taskB":"render active filter","sharedWrite":"filters.ts","independentVerification":false}What to check
Mark `parallelizable=NO`. Combining them into one task is reasonable. Close it after verifying that the active filter state is displayed correctly.

Frequently asked question
Should every task be split by frontend and backend?
Use verifiable outcomes and write boundaries. Keep tightly coupled changes together when they cannot be validated independently.
