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 | $0.00336 | $0.00336 |
| Opus 5 | $0.00168 | $0.00168 |
| Sonnet 5 | $0.00067 | $0.00067 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade A, and why
agent-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 7d 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
AgentOS
Personal open-source AI agent system — TypeScript/Node.js Turborepo monorepo.
Stack
- Node.js 22, TypeScript 5.7 strict, ESM (NodeNext)
- Turborepo monorepo with 4 packages: shared, core, cli, discord
- better-sqlite3 for memory, pino for logging, Zod for config validation
- Claude (Anthropic) + Gemini (Google) as LLM backends
Code Rules
- All imports must include
.jsextension (NodeNext resolution) - No
anytypes. No default exports (except pages). Noconsole.log. - Named exports everywhere.
- Zod validation on all external inputs.
- Try/catch with typed errors on all async operations.
Package Structure
packages/shared— types, config, logger, pricing, settings hierarchypackages/core— engine, LLM clients, memory, MCP tools, skills, hooks, subagentspackages/cli— terminal REPL adapter (aos)packages/gateway— multi-platform messaging daemon (aos-gateway): Telegram, Discord, Slack, WhatsApp, Signal, Matrix, Emailpackages/browser— Playwright browser automation (local + Browser Use cloud)packages/cron— cron scheduler with SQLite persistence and platform deliverypackages/discord— legacy Discord-only adapter (superseded by gateway)
Build Order
shared → core → [cli, gateway, browser, cron, discord, web] (parallel)
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.
