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 | $0.00019 | $0.00523 |
| Opus 5 | $0.00010 | $0.00262 |
| Sonnet 5 | $0.00004 | $0.00105 |
| Haiku 4.5 | $0.00002 | $0.00052 |
Grade A, and why
dart-release-packaging 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 today.
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.

dart-release-packaging
Use this skill in Codex to run the DART dart-release-packaging 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-packaging <arguments> - Codex:
$dart-release-packaging <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
Create release packaging PR after explicit maintainer/user approval: $ARGUMENTS
Required Reading
@AGENTS.md @docs/onboarding/release-management.md @docs/onboarding/contributing.md @docs/onboarding/changelog.md
Workflow
- Confirm the new version, for example
6.16.6. - Derive the release branch:
release-<major>.<minor>. - Fetch and branch from the release branch:
git fetch origin <RELEASE_BRANCH> git checkout -B release/<NEW_VERSION>-version-bump origin/<RELEASE_BRANCH> - Bump versions in
package.xmlandpixi.toml. - Update version requirements in examples/tutorials if needed.
- Invoke the
dart-changelogroutine in release-audit mode, then add or finalize theCHANGELOG.mdrelease section with the release date, milestone link, release summary, and audit fromdocs/onboarding/changelog.md. - Run
pixi run lintand relevant packaging checks. - Commit as
Packaging <NEW_VERSION>. - Ask for explicit maintainer/user approval before pushing, creating the PR, or setting milestones.
- After approval, create the PR against the release branch with the release milestone for that branch, for example the specific version milestone if available.
Output
- PR URL
- Version files changed
- Changelog section added
- Checks run
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.
