Dart New Task

dart-new-task

Use this skill in Codex to run the DART dart-new-task 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-new-task <arguments>
• Codex: $dart-new-task <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

Start a new task in DART: $ARGUMENTS

Required Reading

Read these files first: @AGENTS.md @docs/ai/principles.md @docs/README.md

Then load owners when the task needs them:

• Multi-phase/session work: docs/dev_tasks/README.md before creating or resuming the project home.
• Branching or contribution: docs/onboarding/contributing.md before setup.
• C++/Python/build changes: docs/onboarding/building.md and docs/onboarding/code-style.md before implementation.
• Docs edits: docs/AGENTS.md before editing.
• Acceptance and testing: the task's gate set in docs/ai/verification.md before implementation; load detailed test guidance for the affected surface.

Workflow

1. Understand the task - Parse: goal, constraints, type (feature|bugfix|refactor|docs)
2. Assess scope - Multi-phase or multi-session? Create docs/dev_tasks/<task>/ (see docs/dev_tasks/README.md for criteria). Team-scale work (multiple parallel lanes needing orchestrated worker agents) switches to dart-ultrawork instead. For multi-session, design-heavy, public API, solver/paper, release, or cross-module work, fill the dev-task specification intake before editing: value, scope, assumptions, traceability, non-goals, acceptance evidence, gates, and open decisions. If consequential ambiguity would change public API, release compatibility, numerical correctness, benchmark claims, or roadmap scope, record an owner-local Decision needed block instead of silently choosing.
3. Setup - Choose the target branch before creating a topic branch:
   • features/docs/non-bugfix refactors: branch from origin/main
   • bug fixes that apply to the current release line: branch from the active DART 6 LTS origin/release-6.* branch first, then cherry-pick or reapply to main
4. Implement - Keep commits focused, follow code style
5. Task lifecycle - For an intermediate commit or PR, preserve and update the active task folder. In the completing change, follow docs/dev_tasks/README.md: complete feasible work, promote durable artifacts, and remove the folder before final validation and commit. Preserve the owner's approval requirement for retiring unfinished work.
6. Verify - Run pixi run lint before committing, then the gate set for this task type from docs/ai/verification.md. If the claim depends on 3D structure or behavior, route through dart-verify-sim: text oracle first, then assessed claim-tied visual evidence, or record why it is not applicable.
7. PR - After explicit maintainer/user approval, git push -u origin HEAD then gh pr create --draft --base <target-branch> --milestone "<milestone>" (DART 7.0 for main, branch-matching DART 6.x release milestone for the active DART 6 LTS branch); follow .github/PULL_REQUEST_TEMPLATE.md

Type-Specific

• Bugfix: Requires PRs to BOTH the active DART 6 LTS branch AND main
• Refactor: No behavior changes
• Feature: Add tests + docs
• New solver/paper implementation: record the intake checklist in docs/plans/solver-family-intake.md first and hold the task to the paper-complete bar in docs/ai/verification.md § "Research Paper Implementation Evidence"; the task is not complete until that bar is met.

Output

• Task type, scope, and whether a docs/dev_tasks/<task>/ folder was created
• Files changed and gates run
• Dev-task promotion and cleanup status when the task completed
• PR readiness, noting any external mutation that was explicitly approved
