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 | $0.06349 | $0.06349 |
| Opus 5.5 | $0.02540 | $0.02540 |
| Sonnet 5.5 | $0.01270 | $0.01270 |
| Haiku 4.5 | $0.00635 | $0.00635 |
Grade A, and why
openchief 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 2mo 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 — 454 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenChief
AI agents that passively watch business tools and produce reports via Claude. Open-source, serverless, runs on Cloudflare Workers.
Architecture
- pnpm monorepo + Turborepo —
packages/shared,workers/*,workers/connectors/* - Cloudflare Workers — runtime (Durable Objects), router (Queue consumer), dashboard (React SPA + API), connectors (one Worker per data source)
- Cloudflare D1 — shared database for agents, events, reports, revisions, identity mappings, model settings
- Cloudflare KV — caching layer for subscriptions, reports, user profiles, connector metadata, avatars
- Cloudflare Queues —
openchief-eventsqueue connects connectors to the router - Cloudflare Vectorize — vector index for RAG (long-term memory), stores report/event embeddings
- Cloudflare Workers AI — embedding model (
@cf/baai/bge-base-en-v1.5) for Vectorize indexing and retrieval - Durable Objects — per-agent persistent state with SQLite inbox (events, reports, chat history, reasoning log)
- React + Tailwind CSS v4 — SPA dashboard at
workers/dashboard - Anthropic Claude — LLM for report generation and agent chat (claude-sonnet-4-6 default)

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.
