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 | $0.04127 | $0.04127 |
| Opus 5 | $0.02063 | $0.02063 |
| Sonnet 5 | $0.00825 | $0.00825 |
| Haiku 4.5 | $0.00413 | $0.00413 |
Grade A, and why
joyreactorDownloader 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 4d 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 — 246 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Назначение проекта
Кросс-платформенное (Windows / macOS / Linux) десктопное приложение для
скачивания картинок с Joyreactor по фильтрам, аналогичным штатному поиску
сайта. Главный артефакт — один статичный бинарник без рантаймов:
cmd/joyreactor-gui/build/bin/joyreactorDownloader[.exe|.app].
Стек: Go + Wails v2 (Go-бэк + системный WebView +
HTML/CSS/JS-фронт). Wails использует нативный для платформы движок: WebView2
(Edge Chromium) на Windows, WKWebView на macOS, WebKitGTK на Linux. Параллельно
сохранён CLI (cmd/joyreactor-dl/) — удобен для отладки логики.
Платформенные особенности (что разное по OS):
- Системные toast-уведомления — Windows (нативные WinRT), на macOS/Linux no-op.
- «Открыть папку» —
explorer/open/xdg-openсоответственно. - Single-instance lock — Wails встроенный механизм работает на всех трёх.
Установка Wails-зависимостей на Linux: libwebkit2gtk-4.0-dev libgtk-3-dev pkg-config
(см. .github/workflows/build.yml для актуального списка).
Источник данных
Метаданные постов/медиа — официальный GraphQL API:
- Endpoint:
https://api.joyreactor.cc/graphql(POST JSON{query, variables}). - Playground: https://api.joyreactor.cc/graphql-playground
- Relay Object Identification: глобальный
id=base64("<Type>:<numericId>"). - Полный дамп схемы —
api/schema/introspection.json. - Лимиты жёсткие —
internal/graphql.Clientсериализует запросы и держитminDelay, на HTTP 429 возвращаетErrRateLimited.

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.
