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 | $0.00629 | $0.00629 |
| Opus 5.5 | $0.00252 | $0.00252 |
| Sonnet 5.5 | $0.00126 | $0.00126 |
| Haiku 4.5 | $0.00063 | $0.00063 |
Grade A, and why
3D-AR-Studio 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 18d 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Operating notes for AI coding agents (Claude Code, Codex, Cursor, Copilot and others) working in this repository. Everything here is derived from the files actually in the tree, so trust it over guesses, and update it when the facts change.
What this repository is
Drop a full augmented-reality studio into any web page. Place any number of 3D models in your real room through the camera, generate new ones from a text prompt, arrange them, then share the scene as a link, a QR code, or a live room. WebXR + Quick Look + Scene Viewer, a free CC0 model library, and an MCP server for agents.

Conventions
.envfiles are gitignored; never commit credentials, and read configuration from environment variables.- Commit messages follow Conventional Commits (
type(scope): summary), matching the existing history. - User-visible changes get an entry in
CHANGELOG.md. - Read the surrounding code before adding to it, and match its naming, file organisation and error-handling style.
- Keep
README.mdaccurate: if a change alters behaviour, commands or configuration, update the docs in the same commit. - Do not leave TODO comments, stub functions, placeholder data or commented-out code behind. Finish what you start or leave it out.
- Small, focused commits with a subject line that describes the change, not the act of committing.
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.
