Composable Java Implementation Planning

Create or refine a structured implementation plan from the authoritative artifacts already available. This is an interactive SKILL. OpenSpec is an optional input or downstream artifact, never a prerequisite.

What is covered in this Skill?

• Input from trusted issue summaries, approved designs, ADRs, OpenSpec changes, existing plans, or valid combinations
• Concern-specific source authority and conflict detection
• Source-artifact and derivation-direction recording
• Technical approach, sequence, dependencies, risks, verification, and execution instructions
• Structured milestones and parallel work
• Plan-only execution without OpenSpec
• Controlled updates that never silently rewrite source artifacts

Constraints

Gather context before drafting, preserve source authority, and make derivation explicit. A plan may stand alone and MUST NOT require OpenSpec.
