dart: Command for Claude Code

.claude/commands/dart-fix-ci.md

dart-fix-ci is a command for Claude Code from dartsim/dart. It costs 10 tokens per session (677 once invoked), scanned A, original, BSD-2-Clause.

A workflow for investigating and fixing a failed continuous-integration check. Continuous integration, or CI, automatically builds and tests code when changes are proposed.

In plain words
What is it for?
Use it to inspect failed pull-request or workflow logs, reproduce the problem, choose where to fix it, and verify the correction.
Why use it?
It directs attention to the first real failure and the correct branch, reducing guesswork when a build or test pipeline fails.

Command for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: agent in frontmatter; mentions AGENTS.md.

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-fix-ci 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 yesterday.

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.

Fix CI failure: $ARGUMENTS

Required Reading

Workflow

For a failure that depends on 3D structure or behavior, use dart-verify-sim to reproduce the claim with text and assessed visual evidence, or record why the renderer is unavailable.

  1. Identify the base branch. Default to main; use base=<branch> from $ARGUMENTS or the PR's own base when it is a release-* branch. For a release-* base, also read docs/onboarding/release-management.md and apply the release caveats called out below.
  2. Identify failing checks: gh pr checks <PR_NUMBER> or gh run view <RUN_ID>.
  3. Inspect the first real failure:
    gh run view <RUN_ID> --log-failed
    gh run view <RUN_ID> --job <JOB_ID> --log
    
  4. If a job is still in progress, wait for logs instead of guessing.
  5. Choose where to fix. Check whether an equivalent fix already exists on main. If continuing an existing PR, fetch and check out that PR branch instead of creating a new one. For a release-* base, branch from the release branch and prefer cherry-picking the proven main fix; keep any new fix release-scoped and minimal. Create a uniquely named branch. If the intended branch exists, inspect and resume it within the requested scope or choose a fresh name; do not reset it:
    git fetch origin <RELEASE_BRANCH>
    git switch --no-track -c fix/<unique-topic>-<release-branch> origin/<RELEASE_BRANCH>
    
  6. Reproduce locally with the smallest relevant command:
    • formatting: pixi run lint
    • tests: pixi run test, pixi run test-unit, or another existing focused pixi run ... test task
    • coverage: add targeted tests for uncovered changed lines
  7. Fix the root cause with minimal scope. Explain why the failure was not caught earlier and whether workflow coverage should change.
  8. If the failure is infrastructure-only, ask for explicit maintainer/user approval before rerunning the failed job or running:
    gh run rerun <RUN_ID> --failed
    
  9. Ask for explicit maintainer/user approval before pushing, CI re-triggers, or other GitHub mutations; after approval, push and watch CI until green. For a release-* base, use the current release milestone and the PR template when creating or updating the release-branch PR.

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.
