auto-company: Agent for Claude Code

.claude/agents/critic-munger.md

critic-munger is an agent for Claude Code from nicepkg/auto-company. It costs 70 tokens per session (1,176 once invoked), scanned A, original, no licence file.

A critical-thinking adviser based on Charlie Munger’s mental models. It challenges new ideas, looks for serious flaws, and uses reverse arguments and pre-mortem reviews, which imagine how a plan could fail before it starts.

In plain words
What is it for?
Use it to test plans, question feasibility, identify fatal weaknesses, and review important decisions before committing.
Why use it?
It helps expose weak assumptions and group agreement that may hide risks before a major decision is made.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is nicepkg/auto-company's own configuration. It tells Claude Code how to work on auto-company itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything auto-company configures →

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

critic-munger 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 2mo 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 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.
