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 | $0.00670 | $0.00670 |
| Opus 5.5 | $0.00268 | $0.00268 |
| Sonnet 5.5 | $0.00134 | $0.00134 |
| Haiku 4.5 | $0.00067 | $0.00067 |
Grade A, and why
life_OS AGENTS.md 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Life OS · Repository Guidance
SKILL.md is the sole universal runtime authority for Life OS.
This file guides contributors and coding agents working in the Life OS source repository. It does not define an additional user-facing workflow.
Repository Scope
- Treat the current Life OS checkout as the default development boundary.
- Do not inspect, read, validate, migrate, or modify a user's second-brain unless the user explicitly places that directory in scope.
- Do not infer second-brain access from passive screen context, nearby paths, Git configuration, or prior sessions.
- Preserve unrelated worktree changes.
- Keep historical material as history unless the task explicitly includes archival cleanup.
Authority and Layers
| Layer | Responsibility |

Universal runtime purpose, boundaries, and completion standard |
hosts/*.md |
Host capabilities and adaptation notes |

No host, agent, reference, command, or test document may override
SKILL.md.
Development Principles
- Implement the requested outcome rather than a ceremonial process.
- Use available tools, including Shell and CLI, when they are useful.
- Do not add a script, command, runner, hook, daemon, CI job, or fixed agent chain as a hidden runtime prerequisite.
- Existing agents are optional templates. Use no subagent when direct work is sufficient; create a task-specific subagent when it materially helps and the host supports it.
- Ask the user only for material ambiguity, scope expansion, or missing authority.
- Make the smallest coherent change that leaves active documentation and behavior consistent.
File Changes
- Use scoped, reviewable edits.
- Do not rewrite user data to test a migration; use repository-local synthetic fixtures.
- Do not introduce a second universal specification beside
SKILL.md. - When retiring an old contract, either move it under
docs/history/or mark it clearly non-authoritative and remove active references. - Update directly affected current documentation and conformance scenarios.
- Preserve valid historical records rather than rewriting earlier releases to look current.
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.

life_OS AGENTS.md is an instructions file published in the GitHub repository jasonhnd/life_OS (6 stars, last pushed today), licensed Apache-2.0. It adds 670 tokens to every session, about $0.0027 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
