brownfield-chat

When to use

• "What breaks if I change X?" (multi-file blast radius)
• "Who last touched auth.ts?" (git history)
• "What changed in the last 30 days?" (git diff summary)
• "Which files have no tests and high risk?" (graph filter)
• "What does tokenService do?" (summary lookup)
• "What does X import / who imports X?" (structural lookup)
• Any question spanning multiple modules or layers

When NOT to use

• Architecture rules / boundary enforcement → use brownfield-drift
• About to edit a file → use brownfield-fix first

How to answer — by question type

Answer ALL questions by reading pre-built files with the Read tool. Do NOT call wednesday-skills chat via Bash — read the files directly to avoid opening a terminal.
