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 | $0.01225 | $0.01225 |
| Opus 5.5 | $0.00490 | $0.00490 |
| Sonnet 5.5 | $0.00245 | $0.00245 |
| Haiku 4.5 | $0.00122 | $0.00122 |
Grade A, and why
WhyBuddy 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 1mo 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
The deepest project knowledge lives in code comments and test docstrings, not in
docs. See CLAUDE.md for the project's core engineering disciplines (verify which
code path actually runs before editing, mutation-test your assertions, etc.). Read
it before making changes.
Cursor Cloud specific instructions
These notes are for agents starting in a VM where the startup update script has
already installed dependencies (Node via pnpm install, and the Python venv at
slide-rule-python/.venv). Standard commands live in package.json,
CONTRIBUTING.md, and slide-rule-python/README.md — prefer those; the notes
below only capture non-obvious caveats.
Services and how to run them
This is a polyglot product ("SlideRule / 面团 AI", a product-rehearsal engine).
The four dev services and their run commands are in package.json scripts:
pnpm run dev:all— start the full stack: Vite frontend:3000, Node server:3001, Lobster executor:3031, and Python engine:9700. This is the normal start command.pnpm run dev:stop— stop whatdev:allstarted (and any leftover listeners on those four ports). Restart =dev:stopthendev:all.pnpm run dev:sliderule— lean core loop: Vite:3000+ Python:9700only (frontend proxies/api/slideruleand/api/agent-loopstraight to Python).pnpm run dev:frontend— UI only, no server, no.env(degraded/BYOK).
The authoritative rehearsal engine is the Python service (slide-rule-python,
FastAPI on :9700); the Node server is a thin proxy that delegates V5 calls to
Python. Open the workbench at http://localhost:3000/agent-loop/sliderule.
Python backend requires the venv (non-obvious)
scripts/dev-all.mjs / scripts/dev-sliderule.mjs only auto-start uvicorn when
slide-rule-python/.venv/bin/python exists; otherwise they print a warning and
skip Python (the SlideRule/AgentLoop pages then error until Python is up). The
update script creates this venv. Run Python tests with the venv, from the repo
root, keeping the slide-rule-python/ path prefix (per CLAUDE.md):
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.
