Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00074 | $0.00493 |
| Opus 5 | $0.00037 | $0.00246 |
| Sonnet 5 | $0.00015 | $0.00099 |
| Haiku 4.5 | $0.00007 | $0.00049 |
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.
This is a copy
100% identical to beads — 0 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.
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
- Find work:
bd ready
bd list --status=open
bd list --status=in_progress
- Inspect before editing:
bd show <id>
- Claim work atomically:
bd update <id> --claim
- 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
- 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. Usebd updateflags instead. - Prefer
--jsonwhen parsingbdoutput programmatically. - If hooks are installed,
bd primemay already be injected. Run it manually when context is missing. - Do not auto-close or mutate tasks unless the work is actually complete.
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.
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.

beads is a skill published in the GitHub repository zach-source/claude-mailbox (1 stars, last pushed 1mo ago), licensed MIT. It adds 74 tokens to every session and 493 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to beads, differing in 0 lines, and is treated as a copy.
