| description | Use when the user asks for a written record of what was done — "write it up", "give me a report", "summarize what you changed", "document this cycle" — or at the end of a build/QA cycle ONLY if the project's cycle-report preference is on. Off by default: never produce one unprompted, and skip it for a one-line change. |
report — a receipt for the work
Turn a completed cycle into a concise, skimmable record someone can read without re-reading the diff.
It's the same content as the in-chat verdict, made durable and shareable.
When it runs
- On request — "give me a report", "write up what you did", "summarize this cycle".
- Automatically at the end of
build / qa only if the project preference says so (below).
Default is off — never auto-generate otherwise.
Preference (per project) — off by default
Read .mastermind/prefs.md in the project root for a cycle-report: line — one of:
off (default, and the assumption if the file/key is missing) — never auto-report.ask — at the end of a report-worthy cycle, offer once: "want a report? markdown / html / no".markdown — always write a Markdown report.html — always write a self-contained HTML report.
The init skill sets this once, at the first task. The user can change it anytime ("reports off",
"always give me html reports") — update the line in .mastermind/prefs.md to match.
What goes in it — signal, not a log
- Title + verdict — ship / needs-work / redirect, one line why.
- What changed — files touched (path + one-line what), grouped by area.
- Key decisions — the non-obvious calls and the one-line reason (not what the model already knows).
- How it was verified — what was actually run/observed end-to-end (never "looks right").
- Follow-ups / risks — anything left, edge cases, TODOs.
Keep it tight — a bloated report gets ignored (same rule as the brain: signal density beats volume).
Format
- Markdown (default) — write
.mastermind/reports/<slug>-<YYYY-MM-DD>.md (use today's date), or a
path the user names. Cheap, diffable, opens anywhere.
- HTML (on request /
cycle-report: html) — one self-contained file (inline CSS, no external
assets or scripts), lightly MasterMind-styled, so it opens in any browser. Costs more tokens.
Tool-agnostic: always a plain file on disk — never rely on a tool-specific artifact surface.
Cost & restraint
An HTML report adds meaningful output tokens (~1.5–4k) vs Markdown (~0.4–1k); the in-chat verdict is
~free. Match effort to stakes: for a one-line change, skip the report entirely — offer nothing. Reserve
it for cycles someone would actually want to read or share.
