dart-release-ci-fix

dart-release-ci-fix is a skill for Claude Code, Codex from dartsim/dart. It costs 24 tokens per session (818 once invoked), scanned A, original, BSD-2-Clause.

A workflow for investigating and fixing continuous integration failures on the DART 6.20 release branch. Continuous integration, or CI, automatically builds and tests code when changes are made.

In plain words
What is it for?
Use it to diagnose release-branch CI failures involving DART simulations, physics, model or scene structure, or OpenSceneGraph output.
Why use it?
It provides a defined process for inspecting failed runs, checking the correct branch, reproducing simulation-related problems, and preparing a fix.

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-release-ci-fix 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 3d 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.

dart-release-ci-fix

Use this skill to run the DART dart-release-ci-fix workflow. The editable workflow source lives in .claude/commands/; this generated skill is its entrypoint for Codex and Muse.

Invocation

  • Claude Code: /dart-release-ci-fix <arguments>
  • Codex: $dart-release-ci-fix <arguments>
  • Muse: /dart-release-ci-fix <arguments>

Treat the text after the skill name, or the user's request when the skill is loaded on demand, as $ARGUMENTS. When the workflow references $1, $2, etc., map those to the positional values supplied by the user.

Command Body

Fix DART CI: $ARGUMENTS

Workflow

For a failure involving model/scene structure, physics behavior, or Filament output, use dart-verify-sim to reproduce the claim with text and assessed visual evidence. Document a visual exception when graphics support is unavailable or not applicable.

  1. Inspect the failing run:
    gh run view <RUN_ID> --log-failed
    gh run view <RUN_ID> --job <JOB_ID> --log
    
  2. Resolve the target from the live PR base or failing run's branch. Default to main when no target is specified. Fetch that target and read its docs/onboarding/release-management.md § "Release target"; verify the exact DART <Next release> milestone is open on GitHub. Publishing requires explicit maintainer/user approval.
  3. If continuing an existing PR, fetch and checkout that branch. Otherwise branch from the resolved target branch without resetting an existing local branch:
    TARGET_BRANCH=${TARGET_BRANCH:-main}
    git fetch origin "$TARGET_BRANCH"
    BRANCH=fix/<issue>-${TARGET_BRANCH}
    if git show-ref --verify --quiet "refs/heads/$BRANCH"; then
      git switch "$BRANCH"
    else
      git switch --no-track -c "$BRANCH" "origin/$TARGET_BRANCH"
    fi
    
  4. If a proven fix exists in a named reference, adapt it only when its assumptions exist here; otherwise make the smallest branch-scoped fix. Follow the resolved branch's compatibility rules in AGENTS.md, preserving C++17, its dartpy binder and GUI backend (nanobind and Filament on main and DART 7 release branches; pybind11 and OSG on release-6.20), dart::utils, and downstream Gazebo/gz-physics behavior.
  5. Explain why the failure was not caught earlier and whether workflow coverage should change.
  6. Run pixi run lint and release-relevant build/tests.
  7. Ask for explicit maintainer/user approval before pushing, creating, or updating the PR. After approval, push to the existing PR when step 3 continued one; otherwise open a new draft PR with the resolved next-release milestone and PR template. Then follow docs/onboarding/ai-tools.md § "PR Lifecycle".
  8. Monitor CI until green.

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.
