board-mcp: Instructions file for Codex

AGENTS.md

board-mcp AGENTS.md is an instructions file for Codex, OpenCode from maoxiangzhe/board-mcp. It costs 504 tokens per session, scanned A, original, MIT.

Project instructions for coordinating several AI terminals editing the same board-MCP codebase, including a shared bulletin board for work claims and decisions.

In plain words
What is it for?
Use them when multiple agents work in parallel and need to reserve files, share decisions, handle stalled claims, and report changes.
Why use it?
They reduce file conflicts by requiring agents to check the board, claim files before editing, and report completed work.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is maoxiangzhe/board-mcp's own configuration. It tells Codex and OpenCode how to work on board-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything board-mcp configures →

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

board-mcp AGENTS.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 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.

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.

What it actually says

必读:MCP 公告栏协作规则

你正在和其他 AI 终端并行修改同一个项目。开工前必须先看公告板,否则会撞车。

四条硬规则

  1. 开工前:先调用 get_board 看公告板(先看板头的身份注释行,确认这是当前项目的板), 再用 claim_files 认领你要动的文件。
  2. 公告板唯一存在形式是主目录的 ~/.board-mcp/boards/ 目录,由 init_bulletin 创建。 get_board 提示"公告板还不存在"时,必须调用 init_bulletin 初始化; 禁止自行创建任何板文件(包括项目里的 board.md / 公告板.md)。
  3. 调用工具时不要自行传 project 参数(除非用户明确指定)——自己传参容易 操作到另一块板,造成"我认领了但看板是空的"的假象。
  4. 收尾时:调用 report_done 汇报改动和结果(系统会自动检查冲突)。
  5. 禁止修改其他终端已认领的文件;撞车时先协调,不要硬改。

小提示

  • 认领文件用逗号分隔,例如:src/auth/login.py, src/auth/schemas.py
  • 认领状态含义:干活中 = 文件被占用中;已汇报 / 已取消 / 已过期 = 已释放,可以认领(已过期 = 超 TTL 自动释放,长任务记得重新 claim_files 续期)
  • 项目身份自动识别:git 仓库按 remote.origin.url 区分,同仓库副本天然共享一块板; 非 git 目录由 .board-project 固定身份(init_bulletin 会自动生成)
  • 终端掉线、认领卡住时:调用 release_claim 取消它的认领,或手动改公告板
  • 有需要全体遵守的约定时:调用 post_decision 写进共享决策区
  • 公告板只保留最近 20 条记录,旧的会自动清理

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.
