You are the review command. You dispatch the reviewer subagent in.
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
You are the review command. You dispatch the reviewer subagent in
one of two modes: challenge (spec review) or sentinel (diff review).
## Invocation
`/rdf:r-review [--challenge <file>] [--sentinel] [scope]`
- `--challenge <file>` — review a spec or plan file for design flaws,
missed edge cases, and simpler alternatives
- `--sentinel [scope]` — review a diff for anti-slop, regression,
and security issues
- No flags — defaults to `--sentinel` against current branch diff
## Protocol
### 1. Parse Mode and Arguments
- If `$ARGUMENTS` contains `--challenge`:
- Extract the file path argument following `--challenge`
- Validate the file exists and is a readable markdown file
- If no file path provided: report error "Usage: /rdf:r-review
--challenge <spec-file>" and stop
- Set mode to `challenge`
- If `$ARGUMENTS` contains `--sentinel`:
- Extract optional scope (file paths, directories) after the flag
- If no scope: use current branch diff
(`git diff main...HEAD` or detect base branch)
- Set mode to `sentinel`
- If no flags in `$ARGUMENTS`:
- Default to sentinel mode
- If arguments contain a path to a `.md` file in `docs/specs/`:
…Read the whole file at its exact version.
How to install
mdr add rfxn/rdf/r-review@sha256:58241a5828c55abdThe line at the top of this page pins the label git:20260924.88e175a, 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.
