Split work and hand it over
Combine changes without losing someone else’s work.
Hand off work someone else can verify
Specify ownership, the starting revision and required evidence. Check the revision and test the combined result. Add agents or plugins only when the single-task workflow is clear.
A handoff receipt should identify the exact package received.
Present does not mean loaded
Verify the path, registration and one observed invocation. Disable the package and try again. For shared work, record file ownership and the handoff version.
Having a key in your pocket does not prove it opens the intended door.
Practice
Practice review and handoff with two hypothetical changes. Multiple agents are not required.
Review only model.mjs and its current contract. Compare A: fix search, B: rename title to subject. Write integration-note.md with impact, ownership, decision to retain title and combined checks. Do not edit code, spawn agents or commit.
Check your work
Ownership, contract and conflict decisions are explicit.
The combined result is rechecked rather than inheriting earlier passes.
