beads-rs: Skill for Claude Code

.claude/skills/beads-jj-workflow/SKILL.md

beads-jj-workflow is a skill for Claude Code from delightful-ai/beads-rs. It costs 29 tokens per session (483 once invoked), scanned A, original, MIT.

A development workflow for beads-rs, a project that uses jj for version control and bd for tracking small work items called beads.

In plain words
What is it for?
Use it to start tasks, claim and update beads, create frequent jj checkpoints, and close completed work.
Why use it?
It keeps code changes and task progress organised, especially when one larger project is split into many small pieces of 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

beads-jj-workflow 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 12d 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.

What it actually says

beads-rs Development Workflow

jj for version control, bd for issue tracking. Use together.

First Time This Session?

Run bd prime for a quick, dense tutorial on how beads works and how we use it.

VCS Operations

Use the /using-jj skill for all version control.

  • Resolving conflicts? See the conflicts section.
  • Making PRs? Read github.md first.
  • Messing with the DAG? Read surgery.md.

The Loop

bd ready                    # see what's next
bd show bd-xyz              # understand it
bd claim bd-xyz             # you own it now
jj new                      # start first change

# --- this loop runs MANY times per bead ---
# edit: one coherent thing (add fn, fix bug, write test)
jj describe "bd-xyz: added validation for Foo"
jj new
# edit: next coherent thing
jj describe "bd-xyz: tests for Foo validation"
jj new
# ---

bd close bd-xyz             # bead done, all acceptance met

JJ Rhythm

Commits are checkpoints, not milestones. The loop runs 3-20 times per bead.

  • ~50 lines without jj describe? Too much. Describe and jj new.
  • Touched 2+ unrelated things? Should've been 2 commits.
  • About to context-switch? Describe first.
  • Every commit message includes the bead ID.

Fixing mistakes:

  • Batched too much? jj split
  • Wrong message? jj describe again
  • Reorganize? jj squash, jj rebase -r

Follow-up Beads

Notice out-of-scope work? File a bead immediately:

bd create "Hardcoded 30s timeout in sync.rs:234" --type=bug --priority=2

Don't just mention it in commits—make it trackable.

Verification Before Close

Before bd close:

cargo fmt --all
cargo clippy -- -D warnings
cargo test

All must pass. Then close.

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.
