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.

Security

Grade A, and why

SpexFlow AGENTS.md scanned grade A with 1 finding 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 8d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What it actually says

AGENTS.md (spec-flow scope)

原则

  • 永远遵循最小实现原则;不做“未来可能用到”的扩展。
  • Debug 用 print/console/日志把现状打出来,再判断;不要用“match/猜测式”调试。
  • Fail loudly:不要吞错、不要静默 fallback。
  • 只在真正棘手处加注释,且使用格式:@@@title - explanation

技术约定

  • 前端:React + TypeScript + Vite;画布用 @xyflow/react(React Flow)。
  • 后端:Express + TypeScript,入口 server/index.ts,用 tsx watch 跑。
  • 模块:保持 ESM("type": "module")。

常用命令

  • 安装:pnpm install
  • 开发:pnpm dev(并发启动 web + server)
  • 构建:pnpm build
  • 后端健康检查:curl http://localhost:3001/api/health

常见问题

  • 如果运行 pnpm ... 触发 corepack 报错 Cannot find matching keyid:直接在当前 Node 版本下安装 pnpm(绕过 corepack):
    • npm i -g [email protected] --force(如果提示 EEXIST file already exists)
    • hash -r
    • pnpm -v
    • 仍不生效就先打印确认:which -a pnpm
Changes

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.
