librarian AGENTS.md

librarian AGENTS.md is an instructions file for Codex, OpenCode from omtodkar/librarian. It costs 576 tokens per session, scanned A, original, MIT.

A project instruction file for Librarian, a tool that searches code by meaning and maps how code pieces connect, plus Beads, an issue tracker.

In plain words
What is it for?
Use it when navigating this codebase, finding related files, checking code relationships, claiming issues, and completing development sessions.
Why use it?
It gives coding agents the project’s required search and task-tracking workflow, so they know where to look and how to record work.

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

librarian 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.

How it starts

The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Librarian

This project uses Librarian for semantic search and graph-based code navigation. See .librarian/rules.md for the full guidance.

Before exploring with grep/find, try:

  • librarian search "<topic>" — semantic search over docs + code
  • librarian context "<topic>" — deep briefing: related docs + code refs
  • librarian neighbors <node> — what does X connect to?
  • librarian path <from> <to> — how do these pieces relate?

Read .librarian/out/GRAPH_REPORT.md for a topology snapshot (god nodes, communities, cross-cluster edges).

Beads Issue Tracker

This project uses bd (beads) for issue tracking. Run bd prime to see full workflow context and commands.

Quick Reference

bd ready              # Find available work
bd show <id>          # View issue details
bd update <id> --claim  # Claim work
bd close <id>         # Complete work

Rules

  • Use bd for ALL task tracking — do NOT use TodoWrite, TaskCreate, or markdown TODO lists
  • Run bd prime for detailed command reference and session close protocol
  • Use bd remember for persistent knowledge — do NOT use MEMORY.md files

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
    bd dolt push
    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.
