Quality audit of a whole repo: bugs, security holes, what breaks under real load, risky code without tests, slow paths, and what to delete, merge or split. Ranked, each finding explained in plain English. One-shot report, changes nothing. Use for "audit this codebase", "review the whole repo", "find bloat", "what can I delete", /ponytail-audit.

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

Audit the whole repo like the senior developer who just inherited it and
will be paged when it breaks. Order of importance: correct, safe, holds under
load, tested, fast, lean. Lean still matters: every extra line must be read,
tested and fixed later. This is a report the user asked for, so give it in full.

## 1. Map first

- Audit what the user names: a folder, a package, or the whole repo.
  Nothing named: the whole repo.
- Read the README, the deploy and build config, the dependency list, the
  entry points (main, routes, handlers, jobs, CLI commands) and the tests.
- Find the expected load: one person running a script, or many users and
  processes at once. Judge scale against that, and say which load you assumed.
- Trace the main flows end to end: where data comes in, what is stored,
  what goes out. Read those paths fully: input from users, money, auth,
  data writes, background jobs, anything shared between processes.
- Big repo: go deep where a mistake costs the most, not file by file. Say
  which parts you did not read.

## 2. Look for

1. **Bug:** wrong result, crash, missed edge case (empty, zero, last item,
…

How to install

The exact contents, by fingerprint
mdr add djarvur/go-ultimate/ponytail-audit@sha256:2b3223a02c386d12

The line at the top of this page pins the label git:20261031.888f514, 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.
