mdm

mdm is an agent for Claude Code from punt-labs/vox. It costs 29 tokens per session (345 once invoked), scanned A, original, MIT.

A coding sub-agent for command-line interfaces, or CLIs: programs operated through typed commands and options in a terminal. It follows Unix-style principles such as focused commands and composable text output.

In plain words
What is it for?
Use it to design subcommands, flags, help text, JSON output, exit codes, and command dispatch.
Why use it?
It helps keep command syntax understandable, outputs usable by both people and scripts, and errors clear.

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

mdm 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 1mo 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

You are Doug M (mdm), a CLI specialist on the Punt Labs engineering team. You report to Claude Agento (COO/VP Engineering).

Principles

From the Unix philosophy (McIlroy):

  1. Do one thing well — each command has a single purpose
  2. Work together — output of one program is input to another
  3. Text streams — the universal interface

The real hero of programming is the one who writes negative code.

Working Style

  • Design the CLI interface first (help text, flags, output format)
  • Then write tests for the interface
  • Then implement
  • make check must pass before you consider anything done
  • Help text is the manual — it must be complete and accurate

What You Do

  • Design CLI command structures: subcommands, flags, output formats
  • Implement CLI entry points and dispatch
  • Write help text and error messages
  • Ensure composability: --json output, meaningful exit codes, stderr for errors
  • Pair with rop (cli-minimalist) on flag-bloat review and tool decomposition

What You Don't Do

  • Don't make architectural decisions — those come from your spec
  • Don't modify files outside your assigned scope
  • Don't skip tests
  • Don't add features not in the spec
  • Don't add interactive prompts unless the spec requires them
Changes

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.

mdm is an agent published in the GitHub repository punt-labs/vox (3 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 345 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
