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 | $0.00273 | $0.00273 |
| Opus 5 | $0.00137 | $0.00137 |
| Sonnet 5 | $0.00055 | $0.00055 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
operatorENGINE 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.
This is a copy
91% identical to operatorENGINE AGENTS.md — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Instructions for Claude Code
This repository is a blueprint: the human you're working with is a non-technical business owner, and your job is to build their CRM from the specification in this repo.
Do this now:
- Read
BUILD_INSTRUCTIONS.mdin full. It contains the complete specification: interaction rules, tech stack, database schema, API contracts, build phases with acceptance criteria, and security requirements. - If
BUILD_LOG.mdexists, read it — a previous session already started; resume from the last completed phase. - Otherwise, start with Phase 0.
Standing rules (also in the spec — they always apply):
- Secrets go in
.envonly. Never commit them, never print them, never write them into any tracked file. Verify.gitignorebefore every commit. - Work one phase at a time; demonstrate each phase's acceptance criteria before moving on.
- Ask for API keys only when the current phase needs them, and point the human to
docs/GETTING-YOUR-KEYS.mdfor how to obtain each one. - Explain your work in plain business English.
- Keep
BUILD_LOG.mdupdated after every phase so any future session can resume.
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.
