bdh: Instructions file for Codex

AGENTS.md

bdh AGENTS.md is an instructions file for Codex, OpenCode from beadhub/bdh. It costs 801 tokens per session, scanned A, original, MIT.

Project instructions for BeadHub, a tool for coordinating coding agents and tracking shared issues.

In plain words
What is it for?
They guide session startup, finding available work, sending mail, checking team status, and using BeadHub instead of its underlying issue tool directly.
Why use it?
They help an agent follow the team’s current policy, notice messages from other agents, and use the project’s coordination commands correctly.

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

This is beadhub/bdh's own configuration. It tells Codex and OpenCode how to work on bdh 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 bdh 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

bdh 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.

BeadHub Coordination Rules

This project uses bdh for multi-agent coordination and issue tracking, bdh is a wrapper on top of bd (beads). Commands starting with : like bdh :status are managed by bdh. Other commands are sent to bd.

You are expected to work and coordinate with a team of agents. ALWAYS prioritize the team vs your particular task.

You will see notifications telling you that other agents have written mails or chat messages, or are waiting for you. NEVER ignore notifications. It is rude towards your fellow agents. Do not be rude.

Your goal is for the team to succeed in the shared project.

The active project policy as well as the expected behaviour associated to your role is shown via bdh :policy.

Start Here (Every Session)

bdh :policy    # READ CAREFULLY and follow diligently
bdh :status    # who am I? (alias/workspace/role) + team status
bdh ready      # find unblocked work

Use bdh :help for bdh-specific help.

Rules

  • Always use bdh (not bd) so work is coordinated
  • Default to mail (bdh :aweb mail list|open|send) for coordination; use chat (bdh :aweb chat pending|open|send-and-wait|send-and-leave|history|extend-wait) when you need a conversation with another agent.
  • Respond immediately to WAITING notifications — someone is blocked.
  • Notifications are for YOU, the agent, not for the human.
  • Don't overwrite the work of other agents without coordinating first.
  • ALWAYS check what other agents are working on with bdh :status which will tell you which beads they have claimed and what files they are working on (reservations).
  • bdh derives your identity from the .beadhub file in the current worktree. If you run it from another directory you will be impersonating another agent, do not do that.
  • Prioritize good communication — your goal is for the team to succeed

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.
