agents-board: Instructions file for Codex

AGENTS.md

agents-board AGENTS.md is an instructions file for Codex, OpenCode from fmilioni/agents-board. It costs 2,085 tokens per session, scanned A, original, MIT.

Repository instructions for Agents Board, a project-management board that coding agents use to organize development work.

In plain words
What is it for?
They guide agents in reading and searching cards and documents, managing work status, handling the inbox, and planning new work into cards.
Why use it?
They tell agents where project knowledge lives, how to connect a repository to its board, and which rules take priority.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions .claude-plugin; mentions Claude Code; mentions Codex.

This is fmilioni/agents-board's own configuration. It tells Codex and OpenCode how to work on agents-board 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 agents-board 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

agents-board 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 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.

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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agents Board

Project management for coding agents, exposed over MCP. Codex, Claude Code and Cursor can use the system to organize their own development (auto-inception). International product.

Skills

Two skills ship from a single host-neutral package, plugins/agents-board — Codex reads .codex-plugin/plugin.json, Claude Code reads .claude-plugin/plugin.json + .mcp.json, Cursor reads .cursor-plugin/plugin.json + mcp.json, and all three load the same skills/:

  • agents-board — how to use the board: bind the repo to its project (record projectId + the auth flag in .agents-board.local.md), read and search it, keep a card's status honest, comment, write docs, work the inbox, attach diffs and images.
  • plan — turn a new demand into sprints/stories/cards: clarify, offer research, clarify again, get approval, then write cards a zero-context agent can execute. All card creation goes through here.

The plugin deliberately stops at the board's edge. It ships no implementation, review, worktree or orchestration workflow — how code gets written is the user's process, with whatever skills they prefer. A change to a skill must not smuggle one back in.

Let the skills drive. What to do (active sprint, cards, backlog, comments, docs) is the source of truth and lives in the MCP, not here — query it through the Agents Board MCP tools. Don't duplicate state into this file.

Bind this repo to your board (local, not committed)

This is an open-source repo — every clone tracks its own work on its own Agents Board instance, so the project↔MCP binding is deliberately not committed here. Put yours in a gitignored .agents-board.local.md at the repo root. The coding agent must read it when it exists. For example:

This project in the MCP:

- **slug**: `<your-slug>`
- **keyPrefix**: `<KEY>` (cards are `<KEY>-1`, `<KEY>-2`…)
- **projectId**: `<your-project-id>`

Auth (diff capture) is **ON / OFF** in this deployment.

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.
