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 | $0.01166 | $0.01166 |
| Opus 5 | $0.00583 | $0.00583 |
| Sonnet 5 | $0.00233 | $0.00233 |
| Haiku 4.5 | $0.00117 | $0.00117 |
Grade A, and why
proof-of-commitment 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 6d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Commit
What this is
A browser extension that captures and surfaces real trust signals. Your browsing behavior proves trust — time spent, repeat visits, engagement patterns. Anonymous, verified by World ID. The output: commitment data that AI and humans can query instead of relying on reviews and content.
The thesis
Content is free to fake. Commitment is not. A repeat customer is a stronger signal than a thousand five-star reviews. We prove commitment without revealing identity.
Architecture (v0.2)
Browser extension (Chrome Manifest V3, branded "Commit")
├── World ID login (proof of unique person)
├── Site-contextual popup (trust signals for current domain)
├── Content script (trust badge injected on pages with data)
├── Passive: tracks page visits + time (stored locally)
├── Contributing toggle (user controls data sharing)
├── Brreg integration (Norwegian business registry, .no domains)
├── Active: zkTLS proof on order confirmations / bookings (v0.3)
├── Semaphore: anonymous submission (unlinkable per business) (v0.3)
└── Backend: aggregates per business → API / MCP server
Key decisions
- Site-contextual UI: Popup shows trust data for the current tab's domain, not a personal dashboard. Your data + network data together.
- Contribute/consume duality: Extension both captures your commitments AND surfaces trust from other verified humans.
- Contributing toggle: Users control whether their data syncs to the network. Default on, can be turned off.
- Brreg as ONE feature: Norwegian business registry data surfaces on .no domains. Not the product — one enrichment source.
- Unlinkable claims: Semaphore nullifiers scoped per business (v0.3).
- Live data, not historical: Extension captures behavior as it happens.
- No blockchain for v1: Simple backend aggregation.
- World ID for MVP: Free, global, SDK ready. BankID as upgrade path.

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.
