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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.00543 |
| Opus 5 | $0.00009 | $0.00271 |
| Sonnet 5 | $0.00004 | $0.00109 |
| Haiku 4.5 | $0.00002 | $0.00054 |
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.
How it starts
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
- 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 - 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.
- Confirm CI is green for the PR head:
gh pr checks <PR_NUMBER>. - Merge a reviewed, CI-green bot PR only after explicit maintainer/user approval, using the current head SHA and the repository merge method.
- 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.
