Arc Planning Work

Create implementation plans before coding. The leading word is read-before-plan: inspect the work item and relevant code before proposing tasks.

For the shared plan template, load PLAN_FORMAT.md. For destination-specific commands, load GITHUB_MODE.md, AGILE_ACCELERATOR_MODE.md, or PRD_MODE.md after mode detection. For synchronized docs/ plan and progress artifacts, follow arc-implementation-plan-progress/references/output-contract.md.

Steps

1. Detect the planning source.

   • GitHub mode: issue number/URL, #123, or explicit GitHub issue request.
   • Agile Accelerator mode: W-000000 work item or Salesforce Agile Accelerator story.
   • PRD-to-plan mode: the user asks for an implementation plan from an existing PRD document.
   • If ambiguous, ask where the work item is tracked before planning.

   Completion criterion: the plan has exactly one source mode, or the response stops with a destination/source clarification question.

2. Read the source item.

   • Fetch the issue/story/PRD body and comments where relevant.
   • Preserve the source's acceptance criteria, constraints, and context.
   • Do not create new stories/issues; this skill plans existing work.
