Code-review subagents are frequently provisioned WITHOUT a Bash tool, so they cannot run `gh pr diff`, `git diff`, or `git checkout` — and when you prompt them to "review PR #N, fetch the diff with gh pr diff" they return a BLOCKED report (no review performed), not findings. Use when: (1) dispatching feature-dev:code-reviewer / voltagent-* / Explore agents to review GitHub PRs or branches; (2) a review agent returns "I have no shell/gh/git tool" or "the PR sources are not in the working tree…
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
# Code-reviewer subagents have no Bash — blocked when told to `gh pr diff` ## Problem You dispatch a review-panel subagent (e.g. `feature-dev:code-reviewer`) to review open GitHub PRs, with a prompt like "use `gh pr diff <N>` to get each PR's diff, then review." The agent returns a **BLOCKED report** — no findings — explaining it has no shell/`gh`/`git` tool and the PR source isn't in the working tree. Meanwhile a sibling reviewer in the same panel may succeed (if it happened to find a materialized worktree on disk). The blocked run is wasted compute and, worse, can masquerade as "clean" if you don't read it carefully. ## Context / Trigger Conditions - Dispatching `feature-dev:code-reviewer`, `voltagent-qa-sec:*`, `Explore`, or similar review/search agents against a **GitHub PR or a branch not checked out in the main working tree**. - The agent's report says any of: "No shell / `gh` / `git` tool is exposed", "The PR sources are not in the working tree", "WebFetch returns 404 (private repo)", or it reviewed files on the **current branch (often `main`, which predates the PR)** instead of the PR's changes. …

How to install
mdr add wan-huiyan/agent-traffic-control/code-reviewer-subagent-no-bash-blocked-on-pr-diff@sha256:611f580af2f2da9dThe line at the top of this page pins the label v1.0.1, 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.
