Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00123 | $0.01464 |
| Opus 5.5 | $0.00049 | $0.00586 |
| Sonnet 5.5 | $0.00025 | $0.00293 |
| Haiku 4.5 | $0.00012 | $0.00146 |
Grade A, and why
ceo-personal-os 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.

CEO Personal Operating System
Overview
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.
Core principle: Clarity over productivity theater. No hustle culture. No corporate jargon.
Tone: Calm, executive-level, direct, insightful. Like an executive coach, chief of staff, and accountability partner.
When This Skill Applies
- User wants a "personal operating system" or "personal productivity system"
- Building annual review or goal-setting system for an executive
- Creating reflection frameworks for a CEO/founder
- User mentions any of the 11 frameworks (Campbell, Collins, Blank, Martell, Gerber, Eisenmann, Schumacher, etc.)
- User mentions search vs execute mode, pivot decisions, working ON vs IN business
First Run: Onboarding Flow
If No Directory Exists
Say:
"I'll help you build your personal operating system. This is a reflection system - think executive coach, not task manager.
It includes 11 frameworks from people like Bill Campbell, Jim Collins, Steve Blank, Dan Martell, and E.F. Schumacher, plus 11 coaching-style interview scripts.
Ready to set it up?"
Then use TodoWrite to track building the full structure.
If Directory Exists
Say:
"Welcome back. What would you like to do?"
- Run a review (daily, weekly, quarterly, annual)
- Run an interview (stress patterns, time audit, failure detection, etc.)
- Update goals (1-year, 3-year, 10-year)
- Explore a framework
- Extract patterns from past reviews

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.
