Score how risky a pull request or branch is with fixed rules, and reply with the result as JSON. Use when asked how risky a PR, branch, or diff is, or to gate CI on PR risk.
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
# Risk score This runs in CI, where something reads the JSON and decides whether a PR needs a second reviewer or can merge. That only works if the same diff gets the same score every time. So the score comes from `scripts/score.py`, never from you. Your job is getting the right diff into the script and handing back what it prints, untouched. If a rule looks wrong for this PR, that's a change to the script, made in a PR of its own. Bending one score breaks the thing CI trusts. ## 1. Pick the diff `$ARGUMENTS` decides: - A number, or a GitHub PR URL: the PR. ```bash gh pr diff <number or url> --color=never ``` - Anything else non-empty: a base branch to compare the current branch with. - Empty: the base is `origin/$GITHUB_BASE_REF` when that's set (GitHub Actions sets it on `pull_request` runs), else what `git symbolic-ref --short refs/remotes/origin/HEAD` prints, else `main`. ```bash git -c core.quotePath=false diff --no-color --no-ext-diff --find-renames <base>...HEAD ``` The flags pin the output format, so a user's git config can't change the score. Three dots means the diff since the branch left the base, which is what …

How to install
mdr add thoughtbot/rails-consultant/risk-score@sha256:3bcf89a758450a26The line at the top of this page pins the label git:20261106.ce8ab68, 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.
