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 | $0.00441 | $0.00441 |
| Opus 5 | $0.00220 | $0.00220 |
| Sonnet 5 | $0.00088 | $0.00088 |
| Haiku 4.5 | $0.00044 | $0.00044 |
Grade A, and why
cosmos-os 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
The Cosmos — notes for Claude Code
Commands
npm run dev # dev server on :5173
npm run build # tsc -b && vite build — the gate for every change
npm run validate # data sanity: ids resolve, phaseIds unique, spacing ok
Never run tsc without --noEmit/-b — emitted .js files shadow .tsx in Vite and the app silently serves stale code.
Layout
src/scenarios/— the entire universe as typed data:services.ts,topics.ts,scenarios.ts(domains + scenarios),owners.ts(teams),steps/<domain>.ts, barrel indata.ts. Most changes belong here.src/map/— SVG map rendering:Map.tsx(orchestration, layout edit mode),edge-resolver.ts(how a step becomes edges; special-cases the expandablerealtime-hub),edge-builder.ts(bezier geometry).src/components/— UI shell: intro, playback controls, step panel, tech icons.drift-sync/— the nightly honesty pipeline (its own README)..claude/skills/—add-serviceandadd-scenario: THE documented procedures for growing the map. Follow them rather than improvising.

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.

cosmos-os CLAUDE.md is an instructions file published in the GitHub repository ludeo-labs/cosmos-os (3 stars, last pushed 1mo ago), licensed MIT. It adds 441 tokens to every session, about $0.0022 per session on Opus 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.
