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 | $0.00412 | $0.00412 |
| Opus 5 | $0.00206 | $0.00206 |
| Sonnet 5 | $0.00082 | $0.00082 |
| Haiku 4.5 | $0.00041 | $0.00041 |
Grade A, and why
claudeos-template CLAUDE.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 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.
What it actually says
ClaudeOS — Root Context
Who I am
[Replace this paragraph with 3-5 lines: your name/role, what you're building or working on, and any domain context Claude should always have loaded. Keep it short — this file is read every session.]
See 06-Memory/identity.md and 06-Memory/preferences.md for full detail —
this file stays short on purpose.
How this system is organized
00-System/— conventions and the master index of everything active01-Companies/— every company/product you own, each with nested products02-Career/— your full-time role, if you have one03-StartupIdeas/— pre-venture exploration, not yet a company04-Personal/— personal life, separate from professional context05-Evergreen/— reusable knowledge: Skills, Prompts, Templates, patterns, general research06-Memory/— stable identity, preferences, and standing decisions99-Archive/— retired projects, never deleted

Working with me
[Replace with your own working preferences — tone, depth, format. This is
what makes Claude's output feel like it was written by/for you instead of
generic. Full version: 06-Memory/preferences.md.]
Notion (optional)
If you connect Notion via MCP, treat it as the live operational workspace —
Claude reads it directly, nothing gets copied in. Routing rules:
00-System/conventions/notion-integration.md. Delete this section if you're
not using Notion.
Rules for this repo
- Never duplicate facts across
CLAUDE.mdfiles — link to the canonical source. - Keep each
CLAUDE.mdunder ~150-200 lines — it's loaded every session. - Archive, don't delete.
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.
