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 | $0.02212 | $0.02212 |
| Opus 5.5 | $0.00885 | $0.00885 |
| Sonnet 5.5 | $0.00442 | $0.00442 |
| Haiku 4.5 | $0.00221 | $0.00221 |
Grade A, and why
flutter_tailwind 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 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 — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
⭐ Writing code with this library? Read doc/AI_REFERENCE.md first.
When you need to write flutter_tailwind UI code (chained API: 'x'.text.red.f16.mk, container…child(…), row…children([…])), the single authoritative API cheat-sheet is doc/AI_REFERENCE.md. It has the exact token vocabulary (with numeric rules so you don't invent non-existent tokens like .w73), the entry-point → terminator map, and the builder → supported-axis matrix.
README.md, guide.md, and .cursor/rules/flutter_tailwind.mdc are human-oriented and may be stale (guide.md is mid-migration; the cursor rules contain a stale build_runner instruction). When any of them conflicts with doc/AI_REFERENCE.md or the code, the code wins, then doc/AI_REFERENCE.md — do not trust the others for exact token names.
doc/AI_REFERENCE.md is kept honest by tool/verify_ai_reference.sh — it analyzes doc-coverage fixtures (example/lib/ai_reference_smoke_test.dart, ai_blind_test.dart) that use only documented tokens. Run it after changing presets in lib/ or editing the reference; if a documented token was renamed/removed, it fails.
Project type
This is a Flutter package (UI library), not an application. The library lives in lib/; runnable demos live in example/. There is no top-level Flutter app to flutter run.
The package goal: provide a TailwindCSS-style chained-API for Flutter widgets, e.g.
'Hello'.text.red.f16.bold.mk or container.s100.red.rounded8.border2.child(widget).
Common commands
# Package-level (run from repo root)
flutter pub get
flutter analyze # lint (config: analysis_options.yaml)
flutter test # runs files in test/ — see note below
# Run the demo app
cd example && flutter pub get && flutter run
# Publish flow (see PAY_ATTENTION.md)
flutter pub publish --dry-run
fvm flutter packages pub publish --server=https://pub.dartlang.org
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.

flutter_tailwind CLAUDE.md is an instructions file published in the GitHub repository fastcode555/flutter_tailwind (10 stars, last pushed 3d ago), licensed BSD-3-Clause. It adds 2,212 tokens to every session, about $0.0088 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.
