Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.02552 | $0.02552 |
| Opus 5 | $0.01276 | $0.01276 |
| Sonnet 5 | $0.00510 | $0.00510 |
| Haiku 4.5 | $0.00255 | $0.00255 |
Grade A, and why
wind 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 2d 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Wind UI
Utility-first Flutter styling. Translates Tailwind-syntax className strings into Flutter widget trees through a modular parsing pipeline.
Stack: Flutter >=3.27.0 · Dart >=3.4.0 · Runtime deps: flutter_svg, fluttersdk_wind_diagnostics_contracts. No mockito, no state management library, no router.
Branch: master is the active 1.x stable line (formerly v1). The legacy v0 line lives on the v0 branch.
For architecture / internals, see ARCHITECTURE.md. For the user-facing surface, see README.md. For the LLM-agent inventory, see llms.txt.
Definition of done
A code change is not finished until ALL of these hold for the touched scope. The agent self-checks before reporting work complete:
dart analyzereports zero issues, zero warnings on the touched files.dart format .produces no diff.flutter testreports zero failures (pre-existing skips noted, never new)../tool/coverage.sh 90exits 0 — total line coverage stays at or above 90%. If the change drops coverage, add tests in the same change set, do not lower the threshold.- Every code change triggers the post-change sync below — skipping any of the four sub-surfaces is not optional.
The PostToolUse hooks in .claude/settings.json auto-run format + analyze after .dart edits, so steps 1-2 are mostly automatic in the edit loop. CI re-runs all four gates on push; they are not negotiable there.
Post-change sync (five surfaces, every code change)
When source under lib/ changes, the agent updates each of these in the same change set, BEFORE reporting the work done. Each surface has its own format and acceptance criterion — comply with all five; skipping is a bug.
1. doc/ — the user-facing markdown reference.
- New or changed widget / parser / token / theme field: locate the matching file under
doc/widgets/,doc/layout/,doc/styling/, etc. Format details live in.claude/rules/docs.md. - New widget: create
doc/widgets/<w-name>.mdmirroring the format of the nearest neighbor file (one#title, ToC,<x-preview>tag, Props table withRequired/default/description columns, Constructor signature, Styling Examples, Related Documentation). - Removed surface: delete the doc file or mark deprecated; never leave a stale doc pointing at a removed API.
- Acceptance:
python3 tool/check-docs.pyexits 0. It enforces the whole doc contract: one H1 per page and it is the opening line, relative.mdtargets, fragments, ToC-reachable anchors,<x-preview source>matching a realexample/lib/pages/file (sync surface #2 below), and<x-preview path>matching a route registered inexample/lib/routes.dart.
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.

wind CLAUDE.md is an instructions file published in the GitHub repository fluttersdk/wind (33 stars, last pushed 2d ago), licensed MIT. It adds 2,552 tokens to every session, about $0.0128 per session on Opus 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 2026-08-30.
