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 | $0.04109 | $0.04109 |
| Opus 5.5 | $0.01644 | $0.01644 |
| Sonnet 5.5 | $0.00822 | $0.00822 |
| Haiku 4.5 | $0.00411 | $0.00411 |
Grade A, and why
worldforge 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 — 233 lines — stays where its author put it; the contents beside it link to each section on GitHub.
<priority_rules>
- Keep the scope narrow to the backbone loop: planning and scoring with an action-conditioned predictive world model in latent space, plus evaluation/benchmarking to select configurations. Do not reintroduce world generation, symbolic-scenario simulation, or media-generation features.
- Keep provider capabilities truthful: advertise only callable, tested, typed WorldForge surfaces.
- Make the library fault tolerant and developer-friendly while preserving the optional-runtime boundary: never add torch, LeWorldModel, LeRobot, GR00T, CUDA, checkpoints, datasets, or robot controllers to base dependencies or the repo.
- Fail loudly at boundaries: invalid public inputs raise
WorldForgeError; malformed persisted/provider state raisesWorldStateError; provider/runtime failures raiseProviderError. - Preserve local-first scope: no hosted service, production database, credential store, robot safety layer, telemetry backend, or durable multi-writer persistence unless explicitly designed and approved.
- Public contribution artifacts must be human, maintainer-style, and tool-neutral. Do not mention agent/tool branding in branch names, commits, PR titles, PR bodies, changelog, docs, or README copy. </priority_rules>

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.

worldforge CLAUDE.md is an instructions file published in the GitHub repository AbdelStark/worldforge (108 stars, last pushed 1mo ago), licensed MIT. It adds 4,109 tokens to every session, about $0.0164 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
