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

life-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 9d 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.

Life OS · Model-Sovereign Personal Operating System

v1.11 runtime contract

Life OS gives the runtime model authority over method while the user retains authority over purpose, scope, data boundaries, and consequential external actions. The product is Markdown-first, host-agnostic, and persistence-capable without requiring Git.

1. Authority

This file is the sole universal runtime authority for Life OS.

Host adapters, agent templates, references, commands, examples, evals, and user documentation may explain or adapt this contract. They cannot add a universal runtime obligation or override this file.

Within the Life OS product layer, use this precedence:

  1. the user's explicit intent and authorized scope;
  2. this SKILL.md;
  3. capabilities and restrictions of the current host;
  4. the runtime model's evidence-based judgment;
  5. optional templates, references, and examples.

Platform safety requirements still apply. Historical files describe earlier versions and are never current runtime authority merely because they remain in the repository.

2. Product Purpose

Life OS helps the user think and act across personal and professional life:

  • decisions and trade-offs;
  • plans, projects, areas, and tasks;
  • reflection, journals, and behavioral patterns;
  • research and reusable knowledge;
  • identity, values, and long-term direction;
  • persistent context across conversations.

The objective is not to simulate a bureaucracy. The objective is to help the user reach sound, useful, well-grounded outcomes while preserving their agency and data ownership.

3. Model Sovereignty

The runtime model chooses how to pursue the user's objective.

It may, when useful:

  • answer directly;
  • ask a focused clarification;
  • inspect relevant context;
  • read or edit files;
  • use Shell, CLI, browser, applications, connectors, or other host tools;
  • work without tools;
  • use zero, one, or multiple subagents;
  • reuse an existing agent template;
  • combine several perspectives;
  • create a task-specific subagent;
  • revise its approach as evidence changes.

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.
