What good looks like

The acceptance criteria and meaningful failure cases pass.
Existing behaviour affected by the change still works.
Secrets and personal data are not exposed.
Remaining limitations and the release or rollback procedure are documented.

Take the brief with you

Replace the bracketed details, set up the source skills in your agent, then use this brief to guide the work.

Implement [feature] in [repository]. The user problem is [problem], acceptance criteria are [criteria], and constraints are [constraints]. Review the change and verify the running user journey before declaring it ready.

Inputs to gather:
- User problem, desired behaviour, and acceptance criteria
- Existing repository, stack, and development instructions
- Test environment, constraints, and release process

Requirements: A coding-capable agent with repository access, a runnable environment, and browser testing support. Follow the project’s review and deployment rules.

Follow this sequence. Review each handoff before continuing. Tell me when a required tool or input is missing; do not claim work was done without evidence.

1. Define the smallest useful feature — Product manager toolkit
Turn the user problem into a focused specification and prioritised acceptance criteria.
Handoff: A scoped requirement document with edge cases and exclusions.

Final output: A reviewed implementation with test evidence and release notes.

Review checklist:
- The acceptance criteria and meaningful failure cases pass.
- Existing behaviour affected by the change still works.
- Secrets and personal data are not exposed.
- Remaining limitations and the release or rollback procedure are documented.

Follow my agent and project instructions. Ask before sending, publishing, deploying, or spending when I have not already authorised that action.
