Execplan Decompose

Use this skill only when creating or improving an ExecPlan for work with real sequencing constraints, migration risk, or nontrivial validation requirements.

Do not use this skill for:

• simple bug fixes
• small isolated edits
• straightforward tasks with no real sequencing constraints

Goal

Improve the quality of the final ExecPlan by doing a compact decomposition first.

The decomposition is a means, not the output. The output should be a better ExecPlan in this repository's expected format.

Required workflow

1. Read AGENTS.md, ARCHITECTURE.md, and docs/PLANS.md first.
2. Carry forward:
   • hard constraints
   • major risks and unknowns
   • sequencing implications
   • validation requirements
3. Identify the task structure:
   • prerequisite or foundation work
   • branches that can proceed independently
   • integration or synthesis points
   • validation, observability, rollout, and rollback work
4. Convert that structure into the ExecPlan:
   • milestones in dependency order
   • explicit assumptions and unknowns
   • concrete verification commands
   • recovery or rollback notes when relevant
5. Prefer repository-specific grounding over abstract planning language.
6. If uncertainty remains, encode it as an investigation milestone rather than pretending it is resolved.
