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 | $0.00312 | $0.00312 |
| Opus 5.5 | $0.00125 | $0.00125 |
| Sonnet 5.5 | $0.00062 | $0.00062 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
agent2 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.
What it actually says
@AGENTS.md
Claude Code
Use /brain-clone for new domain expert agents. It should produce agents that
look more like agents/procurement-compliance-officer than example-agent.
Keep this file short. Project-wide rules live in AGENTS.md; detailed framework
context lives in llms.txt, llms-full.txt, and docs/brain-clone-pattern.md.
When editing skills, preserve the Brain Clone concept. Only update skills to point at current canonical examples, runtime behavior, and docs.
Skill routing
When the user's request matches an available skill, invoke it via the Skill tool. When in doubt, invoke the skill — a false positive is cheaper than an ad-hoc answer that misses the structured workflow.
Key routing rules:
- New domain expert / "clone my brain" / "brain clone" → invoke
/brain-clone - New simple agent / "scaffold agent" / "add agent" → invoke
/creating-agents - Agent needs domain knowledge / documents / books → invoke
/building-domain-experts - Add knowledge collections / R2R / ingest PDFs → invoke
/adding-knowledge - Add pause/resume, approval, provider routing → invoke
/adding-capabilities - Agent errors / 500s / mock data / "agent broken" / "doesn't work" → invoke
/debugging-agents - Test agent / QA / "does this agent work" / health check → invoke
/agent-qa
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.
