Decision Complete Planner

Produce a plan another agent can execute without filling in key decisions.

In mainline STRICT or STRICT_OPENSPEC runs, planning must produce JSON-ready artifacts. Markdown summaries may explain the plan, but they do not replace the machine-checkable TaskManifest and WorkPackage objects.

Produce

• Short summary
• Ordered implementation phases
• JSON TaskManifest entries
• JSON WorkPackage entries
• Parallel vs serial execution boundaries
• Acceptance checks per package
• Retry budget assumptions for each non-trivial work package
• Current OpenSpec change and slice status when STRICT_OPENSPEC applies

Use canonical field names from ../ultra-orchestrator/references/contracts.md.

Rules

• Prefer behavior-level decomposition over file-by-file decomposition.
• Mark shared write scope explicitly.
• Treat shared write scope as a write-lock conflict, not a soft warning.
• Keep non-goals visible.
• If a design choice is still unresolved, surface it instead of hiding it in prose.
• For development tasks, prefer one bounded OpenSpec change and one current

slice before dispatch.

• Do not send work to dispatch if artifact validation cannot be planned.

Hand off

Send the plan to $spec-review for completeness, then to $dispatch-and-track.
