What is bilicast AGENTS.md?

Project instructions for bilicast, a tool that sends Bilibili videos to a DLNA television on the same local network. DLNA is a standard that lets devices share and play media over a network.

Use them when modifying the userscript, browser extension, macOS app, cross-platform Go backend, tests, or project commands.

They explain the repository’s components and structure so coding agents and maintainers can make changes without misunderstanding how the browser and desktop parts connect.

Token cost

What it costs to keep this loaded

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	$0.07582	$0.07582
Opus 5.5	$0.03033	$0.03033
Sonnet 5.5	$0.01516	$0.01516
Haiku 4.5	$0.00758	$0.00758

Security

Grade C, and why

bilicast AGENTS.md scanned grade C with 2 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.

一句话定位

把 B 站网页视频投到局域网 DLNA 电视的小工具。两部分：

userscript/ —— Tampermonkey 用户脚本（B 站页面注入"投屏"按钮、抽流地址）
extension/ —— 浏览器扩展（Chrome / Edge MV3），复用同一份内容脚本能力，通过 background bridge 做跨域请求与 token 存储
macos/ —— 纯 Swift 写的 macOS 菜单栏 App（本地 HTTP 控制 API + 流代理 + DLNA 控制）
crossplatform/ —— Wails2 + Go 跨平台后端路线，支持 Wails 桌面客户端、Go daemon、Docker 部署

没有 Xcode 工程文件、没有外部依赖、纯 SwiftPM + bash。 跟 Projects/demo/input-indicator 同一种工程风格。

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.
