md-audit

md-audit is a skill for Claude Code from chaitanyagiri/munder-difflin. It costs 85 tokens per session (368 once invoked), scanned A, original, MIT.

A read-only code quality review that scans the current folder for common problems, such as bugs, unused code, security-sensitive areas, and missing error handling. It returns a prioritised list of findings without editing files.

In plain words
What is it for?
Use it for a quick code audit, issue scan, or first review of an unfamiliar codebase.
Why use it?
It gives you a structured list of likely issues without changing the code being reviewed.

About the project

Munder Difflin is a local multi-agent harness that turns terminal coding CLIs into a coordinated team of agents running on a user's machine. It is for people who want several supported coding agents to communicate, delegate work, retain memory, and operate through a shared office-style interface. The catalogue skills provide workflows for using and coordinating those agents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

md-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Code Audit (read-only)

Perform a read-only code quality scan and return a findings report. Do NOT edit any files.

Steps:

  1. Scope — identify the primary language and entry points (package.json, Cargo.toml, go.mod, pyproject.toml, or similar).
  2. Scan — use Grep and Read to look for:
    • Unhandled promise rejections / ignored errors
    • Hard-coded secrets or credentials (keys, tokens, passwords)
    • TODO/FIXME/HACK comments that signal known debt
    • Dead exports (exported symbols with no in-repo import)
    • Obvious type-safety gaps (unchecked any, missing null guards)
  3. Report — output a findings list sorted by severity (Critical → High → Medium → Low):
    ## Audit Report — <project name>
    
    ### Critical
    - [file:line] <description>
    
    ### High
    - ...
    
    ### Summary
    <total count> findings across <file count> files scanned.
    
  4. Stop after reporting. Do not apply any fixes.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
