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 | $0.00037 | $0.01371 |
| Opus 5 | $0.00018 | $0.00685 |
| Sonnet 5 | $0.00007 | $0.00274 |
| Haiku 4.5 | $0.00004 | $0.00137 |
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 4d 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 — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.
This skill teaches effective use of beads (bd), a distributed git-backed issue tracker designed for AI agents. Use beads to track tasks, manage dependencies, and coordinate work across sessions.
Getting Started
First, check if beads is available and initialized:
# Check if bd is installed
bd version
# Check if current project has beads initialized
bd status
If bd is not installed, ask the user which installation method they prefer:
- npm:
npm install -g @beads/bd - Homebrew:
brew install beads(macOS) - Go:
go install github.com/steveyegge/beads/cmd/bd@latest
Do not install without user confirmation, as these are global system packages.
If not initialized in the project, run:
bd init
For personal use on shared projects (won't commit to repo):
bd init --stealth
For contributors on forked repos (routes to separate planning repo):
bd init --contributor
Essential Commands
| Command | Purpose |
|---|---|
bd ready |
List tasks with no open blockers (what to work on next) |
bd create "Title" -p 1 |
Create a task (priority 0-3, lower = higher priority) |
bd show <id> |
View task details and dependencies |
bd list |
List all open issues |
bd close <id> |
Mark task as complete |
bd update <id> --status in_progress |
Update task status |
bd dep add <child> <parent> |
Create dependency (child blocked by parent) |
bd sync |
Force immediate sync to git |
Always use --json flag for machine-readable output when parsing results.
Task Hierarchy
Beads supports hierarchical IDs for organizing work:
bd-a3f8— Epic (large feature)bd-a3f8.1— Task under epicbd-a3f8.1.1— Sub-task
Create hierarchical tasks:
bd create "Epic: User Authentication" -t epic -p 1
bd create "Implement login flow" -p 1 --parent bd-a3f8
Session Workflow
Starting a Session
# See what's ready to work on
bd ready --json
# Pick a task and mark it in progress
bd update <id> --status in_progress
# View full details
bd show <id> --json
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 block/agent-skills (23 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 37 tokens to every session and 1,371 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
to-issues
Decompose a PRD and/or SPEC into implementable, vertically-sliced Issues with real blocking edges, then create them in your chosen platform (GitHub or Local). Use after /prd (and optionally /prd-to-spec) to turn requirements into agent-ready tickets. Triggers on: create issues, to-issues, 创建issue, 拆解issue, 生成卡片, 创建卡片…
anvil
Orchestrate the smithy workflow and manage durable per-task state under .smithy/tasks/. Use when the user invokes smithy/anvil, wants to create/resume/update task state, or wants the full plan -> clarify -> implement -> review -> verify workflow with results persisted locally.
task-prd-creator
Use this skill when users request new features, enhancements, bug fixes, or any work that needs planning. Creates structured task files and PRDs (Product Requirements Documents) before implementation. Activates for "I want to add X", "implement Y", "create a task for Z", "plan this feature", or any feature request.
aip-tracker
Track Airflow Improvement Proposal (AIP) implementation progress by comparing Confluence specs against codebase evidence. Use when asked to assess, report on, or compare AIP status.
flow-next-pilot
Single-tick autonomous build-loop conductor. One spec or the backlog, one stage per tick (pipeline.chainStages chains qa into make-pr), emits PILOTVERDICT. Use when asked to pilot a spec or backlog.
