review-router SKILL.md skillA
Removed from GitHub on 2026-11-09. The file no longer exists in its repository, and every version below is still saved here. mdr add no longer finds it by name, but a lockfile that pins one of these versions still installs it from its recorded commit, for as long as GitHub keeps that commit.
review-router from arcasilesgroup/ai-engineering is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add arcasilesgroup/ai-engineering/review-router@sha256:d392bfc8fc8d38daPins the contents saved here, the only way to install this file now it is gone from GitHub. What a pinned install does.

Decide which review lanes a change actually needs, then run exactly those — instead of spawning the whole chain at every diff size. Reads the diff's shape and blast radius, maps the evidence to lanes (code, security, a11y, perf, design, build), estimates the cost, shows the routing decision, and executes it. Use when asked to "review this", "check this before I commit/merge", "is this ready", or "what should I run", and whenever a full review would cost more than the change is worth. Prefer…
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
# Route the review `full-review` spawns up to five reasoning agents that each read a real amount of code. On a four-line diff that is more expensive than the change was, and the extra lanes return nothing — which trains people to stop running reviews at all. This skill makes the lane selection a decision based on evidence in the diff, rather than a habit. You decide **which** lanes run and **how deep**. You perform no review yourself. Two rules bound everything below: - **Never route to zero lanes** on a diff that touches first-party source. If the change is genuinely trivial, that is `build-check` plus a targeted `code-audit`, not silence. - **Name what you skipped and why**, in the output. A lane that was never run must never read as a lane that came back clean. This is the same failure `full-review` guards against when an agent dies. ## 1. Resolve scope and stack once Per `.claude/review/CONVENTIONS.md` §1 and §3. Resolve both here, exactly once, and pass the identical strings to every agent you spawn. Agents that resolve their own scope drift apart and their findings stop being comparable — and in a monorepo they can legitimately …

How to install
The line at the top of this page is already the fingerprint pin, because a file GitHub no longer serves cannot be found by its label. With it 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.
