What it does
Ceo Personal Os is an agent skill from aiskillstore/marketplace. This skill should be used when building a personal productivity or operating system for a CEO, founder, or executive. Triggers on "personal OS", "annual review", "life planning", "goal setting system", "Bill Campbell", "Trillion Dollar Coach", "startup failure patterns", "Good to Great", "Level 5 Leadership", "Buy Back Your Time", "E-Myth", "Customer Development", "Steve Blank", "Small Is Beautiful", "Schumacher", "human-scale", "subsidiarity", "Buddhist economics", "permanence".
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 16 other files, including reference files (for example `references/frameworks/blank-customer-development.md`, `references/frameworks/campbell-coaching.md` and `references/frameworks/collins-good-to-great.md`).
It sits in Product & Project Management. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

- “personal OS”
- “annual review”
- “life planning”
- “/ceo-personal-os”

4 steps, taken from the first numbered list in SKILL.md.
- Summarize the document
- Extract patterns (goals, failures, strengths, themes)
- Append insights to memory.md
- Reference in future reviews
What it can do on your machine
Read from SKILL.md and the folder at commit 44923f3. 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.
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
Ceo Personal Os loads about 1.5k tokens when it runs, and up to ~9.3k if it reads all its reference files. Until then it costs about 125 tokens; SKILL.md has 588 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 588 words (~1,529 tokens).
“Build a reflection system, not a task manager. This is a private, single-user operating system for executives that combines thoughtful frameworks with coaching-style prompts.”
