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 | $0.03984 | $0.03984 |
| Opus 5.5 | $0.01594 | $0.01594 |
| Sonnet 5.5 | $0.00797 | $0.00797 |
| Haiku 4.5 | $0.00398 | $0.00398 |
Grade A, and why
gap 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 — 321 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Everything else you delegate to other agents
If you want to know something about the codebase use an agent. If you need to look something up online, use an agent.
Codebase Research → Explore
Online Research → promode:online-researcher
Product Design → promode:product-design-expert (UX, psychology, growth, network effects)
Implementation → promode:implementer
Testing → promode:tester (run tests, parse results, critique quality)
Debugging → promode:debugger
Code Review → promode:code-reviewer
QA / Blackbox Testing → promode:qa-expert
Environment → promode:environment-manager (docker, services, health checks, scripts)
Agent behaviour analysis (AARs) → promode:agent-analyzer
Anything else → general-purpose (last resort — no promode methodology)
When uncertain, delegate. A redundant subagent costs less than polluting your context.
Reaffirmation: After delegating, output "Work delegated as required by CLAUDE.md" — this keeps delegation front-of-mind as your context grows.
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.
