beads

beads is a skill for Codex from zach-source/claude-mailbox. It costs 74 tokens per session (493 once invoked), scanned A, a copy of beads, MIT.

A durable task-tracking system for software repositories, using the bd command-line tool to manage work, dependencies, blockers, and handoffs.

In plain words
What is it for?
Use it to find ready tasks, claim and close work, record blockers, inspect dependencies, and create follow-up tasks.
Why use it?
It keeps project status and follow-up work available across sessions, thread resets, and agent changes instead of leaving it in temporary notes.

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

beads 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 5d 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

What it actually says

Beads

Use Beads as the shared project task system. Local plans, scratch files, and personal memories are useful, but they are not the durable source of truth for project work.

First Step

Run:

bd prime

If that prints nothing, check whether the repository has an active Beads workspace:

bd where

Preferred Route

Use the bd CLI when shell access is available. It is the most compact and direct Beads interface.

Core CLI Workflow

  1. Find work:
bd ready
bd list --status=open
bd list --status=in_progress
  1. Inspect before editing:
bd show <id>
  1. Claim work atomically:
bd update <id> --claim
  1. Create durable follow-up work when implementation reveals new tasks:
bd create "Short title" --description="Why this exists and what needs to be done" --type=task --priority=2
  1. Close completed work:
bd close <id> --reason="Completed"

What Belongs In Beads

Use Beads for:

  • shared project tasks
  • blockers and dependencies
  • discovered follow-up work
  • work that must survive thread reset, compaction, or handoff
  • status that another person or agent should be able to resume

Use agent-local planning tools only for the current turn's execution checklist. Do not treat them as shared project state.

Rules

  • Do not create markdown TODO files as the source of truth when Beads is available.
  • Do not use bd edit; it opens an interactive editor. Use bd update flags instead.
  • Prefer --json when parsing bd output programmatically.
  • If hooks are installed, bd prime may already be injected. Run it manually when context is missing.
  • Do not auto-close or mutate tasks unless the work is actually complete.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
