dart: Skill for Claude Code

.agents/skills/dart-deps/SKILL.md

dart-deps is a skill for Claude Code from dartsim/dart. It costs 18 tokens per session (543 once invoked), scanned A, original, BSD-2-Clause.

A workflow for reviewing automated pull requests that update dependencies or maintenance files. Dependencies are external libraries and tools a project relies on.

In plain words
What is it for?
Use it to list dependency-bot pull requests, inspect their changes, check pinned versions, and recommend whether they should be merged or revised.
Why use it?
It helps separate safe update work from changes that need closer review, while keeping merging behind explicit approval.

Skill for Claude Code

Written for Claude Code: $ARGUMENTS substitution. Also seen: reads .claude/ paths; positional $N argument; mentions Claude Code.

This is dartsim/dart's own configuration. It tells Claude Code how to work on dart itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything dart configures →

About the project

DART is an open-source C++23 physics engine that simulates the movement and interactions of articulated rigid-body systems for robotics, animation, and machine learning. Researchers and developers use it for kinematics, dynamics, collision handling, constraints, and loading robot models, with C++ and Python interfaces. The catalogue add-ons support workflows built around this engine.

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

dart-deps 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 2d 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.

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

dart-deps

Use this skill in Codex to run the DART dart-deps workflow. The editable workflow source lives in .claude/commands/; this file is its generated adapter in the shared .agents/skills/ catalog.

Invocation

  • Claude Code: /dart-deps <arguments>
  • Codex: $dart-deps <arguments>

Treat the text after the skill name as $ARGUMENTS. When the workflow references $1, $2, etc., map those to the positional values supplied by the user.

Command Body

Triage and shepherd dependency and bot PRs: $ARGUMENTS

Required Reading

@AGENTS.md @docs/onboarding/ci-cd.md @docs/onboarding/contributing.md

Scope

Handle automated dependency and maintenance PRs: Dependabot GitHub Action version bumps and the scheduled lockfile PRs opened by update_lockfiles.yml. Default to read-only triage; merging any bot PR is an explicit approval gate.

Workflow

  1. List open bot PRs:
    gh pr list --repo dartsim/dart --state open \
      --search "author:app/dependabot OR author:app/github-actions" \
      --json number,title,headRefName,author
    
  2. For each PR, review the diff (gh pr diff <PR_NUMBER>):
    • Action bumps: confirm the new ref is a pinned commit SHA and sanity-check the upstream changelog for the bumped version.
    • Lockfile PRs: confirm the regenerated lockfile provenance matches the workflow that produced it and that no unrelated content changed.
  3. Confirm CI is green for the PR head: gh pr checks <PR_NUMBER>.
  4. Merge a reviewed, CI-green bot PR only after explicit maintainer/user approval, using the current head SHA and the repository merge method.
  5. Batch-report every triaged PR with its recommendation and status.

Output

  • Table of open bot PRs with kind (action bump or lockfile), CI state, and recommendation
  • Diff-review notes per PR
  • Which PRs were merged after explicit approval and which remain pending

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.
