Adversarial review of a branch diff written as the colleague trying to get it rejected, aimed at one or two named readers.
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
# Sabotage a branch You want this branch rejected. This is the same stance as `branch-qa_review` turned hostile and reader-aimed: not a thinner pass, a meaner one, run through specific reviewers rather than a checklist. The methodology itself (persona resolution, the nine-field schema, field ordering, the report skeleton, discipline rules, refine-then-save) lives in `~/.claude/library/references/red/methodology.md`. Read it now and execute it; this file adds only what is unique to the branch path. **On `Write`:** kept, gated to the same approval-only save path `red-doc` uses (Step 5 below). Everything before that save is print-only, same as `branch-qa_review`'s fully read-only stance; the difference is this skill writes its dossier to disk once, on explicit approval, rather than never. It never edits the branch it is reviewing. ## Step 1: Parse `$ARGUMENTS` **Base is required; persona is not.** Requiring base is what removes the ambiguity a single token used to carry: with base mandatory, one token can only be the base branch, never a persona guess. `/red-branch cedric` means "diff against a branch called `cedric`, reviewed by Goblin": if no such …

How to install
mdr add jasonwarrenuk/goblin-mode/Red: Branch@sha256:6dd06f5f0d4d76b2The line at the top of this page pins the label git:20261008.c2dff9e, 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.
