Use to decide which refinement and hardening tools are worth running on a set of changes — refine, crap-analyzer, arch-check, introversion scan, mutation testing, TLA+ model checking, Lean proofs — and on which files, with the invariant to check. Triggers — "/engineer.refinement-advisor", "what should we harden", "which checks fit this diff", "is this worth TLA+ / Lean", "should we model-check this", "how do I harden this change". Called by /engineer.harden at CP8; also usable ad hoc on any…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# refinement-advisor

Reads a diff and recommends which of the DAE refinement/hardening tools to run,
where, and why. It **advises; it does not run the tools.** The expensive ones
(TLA+, Lean) cost real minutes each, and running every tool on every diff buries
the one finding that matters under noise from checks that never fit the code.

The advice is only as good as its reading of the code: read the changed
functions, not just filenames or the diff stat.

## When to use

- Called by `/engineer.harden` (CP8) to pick that checkpoint's tools.
- Ad hoc: "which checks fit this change?", before a risky merge, or when
  deciding whether a piece of code deserves formal verification.

**Not for:** running the tools (`harden`, or the tools' own skills), or reviewing
code quality itself (`refine`).

## Inputs

- **Scope** — a feature dir (diff = feature branch vs its branch point), a fix
  record, a PR, or an explicit ref range. Default: current branch vs its merge-base
  with the default branch.
- **Stage** (optional) — `refine`, `verify`, `harden`, or `any` (default). Limits
  the recommendations to that stage's tools.
- **Prior results** (optional) — if a CP7 handoff exists, read its
…

How to install

The exact contents, by fingerprint
mdr add swingerman/engineer/refinement-advisor@sha256:9fb8758eb3e0afb2

The line at the top of this page pins the label git:20260923.5520e1e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
