biff AGENTS.md

biff AGENTS.md is an instructions file for Codex, OpenCode from punt-labs/biff. It costs 588 tokens per session, scanned A, a copy of dspy-skills AGENTS.md, MIT.

A set of instructions for biff, a project that tracks work with command-line issues called beads. It describes how to find, claim, complete, check, publish, and hand over work.

In plain words
What is it for?
Use it when taking on an issue, implementing or reviewing a change, running quality checks, closing work items, or preparing a handoff.
Why use it?
It makes the project's completion process explicit, including required checks and pushing changes to the remote repository. This prevents finished work from being left untracked or unpublished.

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

biff 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 3d 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.

Origin

This is a copy

84% identical to dspy-skills AGENTS.md — 35 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent Instructions

This project uses bd (beads) for issue tracking. Run bd onboard to get started.

Quick Reference

bd ready --limit=99   # Find available work (show all)
bd show <id>          # View issue details
bd update <id> --status in_progress  # Claim work
bd close <id>         # Complete work

Workflow

This repo delegates non-trivial work through ethos missions, not a tiered slash-command system — see "Workflow: Ethos Missions and Pipelines" in CLAUDE.md for mission archetypes (implement, design, test, review, report, task) and pipeline selection (quick, standard, full, product, formal, docs, coe, coverage).

Session Close Protocol

Follow the protocol in CLAUDE.md. The short version:

  1. File issues for remaining work (bd create)

  2. Quality gates must pass (make check)

  3. Close beads for finished work (bd close <id>)

  4. Push to remote — work is NOT complete until git push succeeds:

    git pull --rebase
    git push
    git status  # MUST show "up to date with origin"
    
  5. Hand off — provide context for next session

PR workflow (see CLAUDE.md): Do NOT merge a PR immediately. Trigger GitHub Copilot code review, wait for feedback, evaluate and address valid issues, ensure quality gates pass, then merge.

Landing the Plane (Session Completion)

When ending a work session, you MUST complete ALL steps below. Work is NOT complete until git push succeeds.

MANDATORY WORKFLOW:

  1. File issues for remaining work - Create issues for anything that needs follow-up

  2. Run quality gates (if code changed) - Tests, linters, builds

  3. Update issue status - Close finished work, update in-progress items

  4. PUSH TO REMOTE - This is MANDATORY:

    git pull --rebase
    git push
    git status  # MUST show "up to date with origin"
    
  5. Clean up - Clear stashes, prune remote branches

  6. Verify - All changes committed AND pushed

  7. Hand off - Provide context for next session

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.
