Use when the user types /sniff, or asks to "scan this project for bugs", "find bugs in my app", "QA my site", or "walk my app and tell me what's broken". For a running web app, finds real, reproducible issues (broken pages/links, console & network errors, broken forms, empty/placeholder data, state-loss, bad loading/error states, responsive and accessibility problems), each with reproduction proof, severity, confidence, and a fix. No API key needed.
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
# /sniff: find real bugs in this project
## What to do
1. Call the unified `sniff` MCP tool with:
- `mode`: `"walk"`, the autonomous flow-walk that drives a real browser and finds runtime bugs (this is the one that matters; `"scan"` is source-only)
- `rootDir`: the current project's absolute path
- omit `baseUrl` to auto-detect the running dev server, or pass it if the user gives a URL
2. If the response is `{ needsSetup: "playwright-browsers" }`, call the `sniff_install` tool, then retry the walk.
3. If no app is running, sniff returns a note + a source-only scan. Tell the user to start their dev server (or pass a URL) for the full flow-walk that finds the real runtime bugs.
4. Present findings grouped by severity (CRITICAL and HIGH first). For each, show the **route**, the **reproduction steps**, the **confidence** (confirmed / likely / uncertain), and the **suggested fix**. Mention any finding marked `needsOutOfBandVerification` (e.g. "submitted but no success shown, confirm the email/job actually ran"). Offer `/sniff-fix` for the safe, auto-fixable ones.

How to install
mdr add aboudjem/sniff/sniff@sha256:cd8a8d093b6d29b2The line at the top of this page pins the label git:20260530.e3585ca, 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.
