When your agent uses it
- Tasks that involve Stock and market analysis
Example prompts
- “/common-sense-index-investing-bogle”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- List each fund's exposure, cost, turnover, tax efficiency, and complexity.
- Apply broad-market and cost tests.
- Identify conflicts or performance-chasing risks.
- Give Bogle-style verdict: prefer, avoid, simplify, or needs data.
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
Common Sense Index Investing Bogle loads about 2.3k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 1,061 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 1,061 words (~2,306 tokens).
