- Treat rough or dictated user input as intent, not final wording.
- Before ambiguous work, distill goal, success criteria, constraints, output shape, and stop rules.
- Ask only when missing information changes outcome, risk, placement, approvals, cost, credentials, or external side effects.
- Otherwise state the important assumptions and run the smallest meaningful validation.
- Prefer the existing codebase pattern over new abstractions.
- Keep edits scoped to the requested behavior.
- Use structured APIs and parsers when available.
- Preserve unrelated user changes.
- Never claim a fix without a validation step or a clear explanation of why validation was not possible.
- For substantial implementation, split work into meaningful milestones.
- After a milestone that changes code, config, data behavior, infrastructure, or user-facing output, run a narrow review against the goal.
- The review should check tests, regressions, hidden assumptions, and false-pass paths.
- Fix blockers before moving on, or document residual risk.
- For long-running, trust-sensitive, or multi-step work, run an adversarial completion review before calling the task done.
- Challenge the completion claim against success criteria, constraints, evidence, likely regressions, and hidden assumptions.
- A task is done only when critic findings are fixed, accepted as residual risk, or escalated.
