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 | $0.00020 | $0.00554 |
| Opus 5 | $0.00010 | $0.00277 |
| Sonnet 5 | $0.00004 | $0.00111 |
| Haiku 4.5 | $0.00002 | $0.00055 |
Grade A, and why
dart-release-merge-main 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
dart-release-merge-main
Use this skill in Codex to run the DART dart-release-merge-main 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-release-merge-main <arguments> - Codex:
$dart-release-merge-main <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
Merge release branch into main: $ARGUMENTS
Required Reading
@AGENTS.md @docs/onboarding/release-management.md @docs/onboarding/ci-cd.md
Workflow
- Auto-detect or confirm the active release branch and release version:
git fetch origin git branch -r | grep -oE 'origin/release-[0-9]+\.[0-9]+' | sort -V | tail -1 - Verify the clone is not shallow and a merge base exists.
- Create
merge/<release-branch>-into-mainfromorigin/main. - Merge the release branch with a title like
Merge release-6.20 into main (v6.20.x). - Resolve conflicts using
docs/onboarding/release-management.md:- deleted in main, updated in release: keep deleted
- added in both: prefer main unless release has unique needed content
- content conflicts: prefer main modernization except for manually reviewed changelog entries
- files only on release: keep if still relevant to main
- Verify no unresolved conflicts remain.
- Run
pixi run lintand relevant checks. - Ask for explicit maintainer/user approval before pushing or creating the PR.
After approval, create a PR targeting
mainwith milestoneDART 7.0and use the PR template. - Monitor CI until green.
Output
- PR URL and CI status
- Release branch and release version
- Conflict counts and resolution summary
- Any manual changelog decisions
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.
