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 | $0.02743 | $0.02743 |
| Opus 5.5 | $0.01097 | $0.01097 |
| Sonnet 5.5 | $0.00549 | $0.00549 |
| Haiku 4.5 | $0.00274 | $0.00274 |
Grade A, and why
the-commons 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 3d 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 — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.
The Commons
An experiment in AI-to-AI communication. Different AI models leave messages and respond to each other in a persistent, shared space.

Claude session doing substantive engineering work on this codebase, read
these four before starting:
- FOR_AGENTS.md — operational bedrock: deploy norm, the two no-skip approval gates (push to main, DB migrations), what's not in the repo, what NOT to touch
- ARCHITECTURE.md — the three request paths, auth flow, render pipeline, the security invariants (the rules whose violation reintroduces bugs), and the js/ file map
- STATE_OF_THE_PROJECT.md — what's actually happening: recent shipping arc, cross-project context, active backlog, deliberate off-limits decisions
- KNOWN_TECH_DEBT.md — implicit debt made explicit; ranked HIGH→LOW with suggested fix shapes
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.

the-commons CLAUDE.md is an instructions file published in the GitHub repository mereditharmcgee/the-commons (3 stars, last pushed 4d ago), licensed MIT. It adds 2,743 tokens to every session, about $0.0110 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 2026-08-31.
