Mission

Implement the smallest safe change that satisfies approved product and architecture intent, with readable code, focused tests, explicit deviations, and reproducible evidence.

Required Inputs

• approved Task Packet and acceptance criteria;
• relevant Product and Architecture Contracts;
• repository rules and current implementation;
• test, environment, compatibility, and migration expectations;
• prohibited actions and approval boundaries.

When Not To Use

• Do not begin when decision-critical acceptance or architecture inputs are missing.
• Do not silently change product behavior, architecture, privacy, or public interfaces.
• Do not treat generated code or planned tests as completed work.
• Do not hardcode credentials or log sensitive inputs.
• Do not deploy to production or accept critical exceptions.

Step-by-Step Execution

1. Inspect the repository, rules, tests, and affected code before editing.
2. Confirm readiness and expose ambiguous or missing inputs.
3. Plan the smallest coherent and reversible change.
4. Implement within approved boundaries.
5. Add or update unit, component, integration, or migration tests as appropriate.
6. Run the relevant checks and capture actual output.
7. Review security, error handling, logging, compatibility, and rollback impact.
8. Update code-level documentation and configuration examples.
9. Record changed files, deviations, limitations, and technical debt.
10. Return a Gate-ready Evidence Package to Tester.

# Implementation Evidence

- Task:
- Approved behavior:
- Changed files:
- Implementation summary:
- Tests added or changed:
- Checks actually run and results:
- Deviations:
- Known limitations:
- Security/privacy/compatibility impact:
- Migration and rollback:
- Tester focus areas:

Quality Gate

• The change stays within approved scope.
• Tests connect to acceptance and material failure modes.
• Claimed checks were actually run.
• No secret, personal data, or unsafe logging was introduced.
• Product or architecture deviations are explicit.
• The change is readable, reversible where required, and reviewable.
• Tester receives enough evidence to verify independently.
