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 | $0.04792 | $0.04792 |
| Opus 5.5 | $0.01917 | $0.01917 |
| Sonnet 5.5 | $0.00958 | $0.00958 |
| Haiku 4.5 | $0.00479 | $0.00479 |
Grade A, and why
agent47 AGENTS.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 11d 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 — 397 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Shared human-facing design
Read DESIGN.md before changing websites, apps, email, HTML reports, graphics
or video. It is the versioned BMD human-first reference. Generated
design-tokens.json and design-tokens.css carry its shared values; use the
existing renderer or bundler to consume them when a surface is migrated.
Project implementation notes must follow this rubric.
Run python scripts/check_design_contract.py to detect local artifact drift. Update the
reference and generated values together from the canonical design export.
Keep automated parity, responsive/accessibility checks, visual critique and
human comprehension evidence separate. A current token file does not certify
a rendered surface. Existing surfaces require their own reviewed migration.
READ THIS FIRST: SDK Memory
Before touching any code, read these tracked SDK-only memory files. They are the ground truth for this public repository.
memory/state.md— SDK version, packaging state, current focusmemory/blockers.md— what is blocked, deferred, or not worth more cyclesmemory/decisions.md— locked SDK product decisions. Do NOT contradict.memory/distribution.md— positioning, channels, and audience for SDK growth
Updated regularly. If memory/ conflicts with older info in this file, memory/ wins.
Cofounder Inbox
Use inbox/ to communicate concise SDK status to the cofounder agent.
inbox/log.mdis the durable handoff file.- Write one entry after each merged PR.
- Format each entry as: date, agent, what shipped, decisions made, blockers.
- Keep it SDK-only and short.
- Do not dump business-sensitive plans there.
- After every merge, also send the owner a short user-facing TLDR (what shipped, what did not, next only if already authorized). Do this even when someone else merged the PR.
Key constraints:
- SDK stays free, MIT, zero-dependency. This is non-negotiable.
- Do not build paid features in this repo.
- Distribution > features. Get listed on registries before building new guards.
- Focus is runtime enforcement + coding-agent safety.
- Do not store business-sensitive plans or outreach data in this repo.
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.
