Comet Open

This skill guides you through the initial phase of structured change management, helping you explore ideas thoroughly and produce a clear proposal document.

Comet Open is the entry point for creating a new change. It walks you through requirement exploration, ensures your scope is well-defined, and produces three foundational artifacts: a proposal (the "why" and "what"), a design summary (the "how" at a high level), and a task list. The skill enforces decision checkpoints at key moments—such as when confirming requirements are clear, choosing a change name, and reviewing the final documents—to prevent ambiguity from creeping into later phases.

What it does

• Explores your idea and clarifies requirements by loading the openspec-explore skill, asking you targeted questions about goals, non-goals, scope boundaries, known unknowns, and acceptance scenarios.
• Detects large or multi-faceted requests and optionally recommends splitting them into multiple independent changes before proceeding.
• Confirms requirement clarity with you before creating any artifacts, ensuring the scope is locked down.
• Generates three core documents:
  • proposal.md (problem, goals, scope, non-goals)
  • design.md (high-level architecture, approach choices)
  • tasks.md (checklist of work items)
• Initializes change state by creating .openspec.yaml, .comet.yaml, and the change directory structure.
• Pauses for your review and sign-off on all three documents before automatically advancing to the design phase.

How to use it

Trigger /comet-open when you have a new idea or feature you want to propose. Bring a description of what you're trying to accomplish—as detailed or rough as you like. The skill will lead you through a series of questions to clarify the problem, scope, and success criteria. At each major decision point (requirement confirmation, change name selection, and final document review), the skill will pause and ask you to confirm before moving forward. Once you approve the three documents, the skill applies state guards and automatically transitions the change into the design phase.
