When your agent uses it
- Munger checklist
Example prompts
- “/munger-mental-models-worldly-wisdom”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Classify the user's request as investment evaluation, bias diagnosis, general decision review, or Munger-style synthesis.
- Apply only the dimensions required by the query. Do not force every checklist into a narrow question.
- Start with competence boundaries and inversion whenever the user asks for a recommendation.
- Use citations for major Munger-derived claims by loading the closest relevant quote file and citing an anchor.
- If the user needs current market or company facts, state what data is missing or browse current sources if available.
What it can do on your machine
Read from SKILL.md and the folder at commit e5ba66c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Munger Mental Models Worldly Wisdom loads about 4.3k tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 2,055 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,055 words (~4,313 tokens).
“This skill turns Charlie Munger's Poor Charlie's Almanack into an executable decision tool for investment evaluation, business judgment, and psychological misjudgment diagnosis. It helps users combine multidisciplinary mental models, inversion, circle-of-competence discipline, and bias checklists into structured recommendations.”
