Non-negotiable rules:

1. Use the helper scripts under .agents/skills/cost-estimate/helpers/ instead of redoing LOC, session, or cost math manually.
2. Keep scope explicit: full repo, branch:<name>, or commit:<hash>.
3. Separate raw engineering hours from organizational overhead and team multipliers.
4. Keep the pricing rubric and report schema in references, not inline in the invocation path.
5. Treat external market-rate research as optional. Use built-in rates unless the user explicitly requests a different market or region.
