What is SpexFlow AGENTS.md?

Project-specific instructions for SpexFlow, covering its agent rules, technical conventions, common commands, and known problems.

Use them when developing or debugging the project's React and TypeScript frontend, Express backend, or React Flow canvas.

They give a coding agent the local decisions and commands needed to work consistently in that project.

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	$0.00341	$0.00341
Opus 5.5	$0.00136	$0.00136
Sonnet 5.5	$0.00068	$0.00068
Haiku 4.5	$0.00034	$0.00034

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 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.

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.
