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 | $0.04004 | $0.04004 |
| Opus 5.5 | $0.01602 | $0.01602 |
| Sonnet 5.5 | $0.00801 | $0.00801 |
| Haiku 4.5 | $0.00400 | $0.00400 |
Grade A, and why
expo-mobile-template 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 2mo 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 — 288 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Source of truth for every AI coding tool used in this repo — Claude Code, Codex, Cursor, Copilot, Gemini, Windsurf, or anything else. Other tools' config files are pointers to this one. Edit this file; never fork its content into a tool-specific file.
0. Start here, every session
Read docs/HANDOFF.md before your first edit. It is one file
describing where the project stands right now — including work left half-finished by
whichever tool ran last.
This repo is expected to be worked on by different assistants at different times: Claude Code
until its usage runs out, then Codex, then Cursor, then back again. HANDOFF.md is the baton
they pass. It only works if everyone honours both halves of the contract:
| Before your first edit | Read docs/HANDOFF.md. If its Next step is populated and the user hasn't asked for something else, that is your task. |
| At every checkpoint | Update it. Not at the end — at checkpoints. Usage limits and crashes do not give notice, and a session that dies mid-task leaves nothing behind but this file. |
Full rules: .agents/handoff.md.
1. What this repo is
An Expo (React Native) mobile template designed to be cloned and driven by an AI agent. Someone clones it, tells their assistant "give me a dark theme with rounded cards", and the assistant has enough written context here to do it without guessing.
| Expo SDK | 57 |
| React Native | 0.86.2 |
| React | 19.2.3 (React Compiler enabled) |
| Router | expo-router v57, file-based, typed routes |
| Language | TypeScript 6, strict: true |
| Package manager | npm (not pnpm — Expo native module resolution) |
Phase status
| Phase | Scope | State |
|---|---|---|
| 0 | Expo scaffold, agent layer, docs | ✅ done |
| 1 | Design system — navigation, headers, auth, cards, drawers, buttons, forms, collections, charts, calendars, icons, tokens | ✅ done |
| 2a | Named theme presets | ✅ done |
| 2b | UX/UI review agents | ⏳ not started — do not start without the maintainer's signal |
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.
