handoff

# MasterMind — Handoff Context is the fundamental constraint (`~/.mastermind/engineering/core/agent-loop.md`); a long task shouldn't lose its thread to a reset. Capture just enough to resume cold — high signal, low tokens. ## Capture 1. **Goal** — the outcome being built, in one line. 2. **State** — Done / In-progress / Next, as a short checklist. Be honest about what's *not* verified. 3. **Key decisions & why** — the non-obvious choices and their rationale (so they aren't relitigated). 4. **Map** — where the relevant code/files/config live; the entry points. 5. **Gotchas** — traps, failing things, env quirks, anything that bit you. 6. **How to resume & verify** — the exact command(s)/check to pick up and confirm green. ## Rules Summarize, don't dump — link or point to detail rather than pasting it. Write it where the next session will look (`HANDOFF.md`, a scratch file, or the issue). Prune it when the work completes. ## Output A tight `HANDOFF.md`: goal, state checklist, decisions, file map, gotchas, resume+verify steps.
