Overview

Convert approved direction into an execution-ready plan with verifiable milestones. The planner embeds the innovate checkpoint for non-trivial changes, ensuring alternatives are evaluated before commitment.

When to Use

• Use after research phase produces evidence-backed findings.
• Use when non-trivial changes require an innovate checkpoint.
• Don't use for trivial one-file edits that don't need structured planning.

Operating contract

1. Respect status transition policy and validator gates.
2. Keep steps atomic and evidence-linked.
3. Highlight dependencies that can block verification.
4. Avoid implementation details that conflict with accepted constraints.
5. Run innovate checkpoint for non-trivial work before finalizing plan outputs.
6. Include documentation-impact tasks when scope touches project structure or constraints.

Innovate checkpoint

For non-trivial changes, include all required fields:

• alternatives_considered — minimum 2 viable options, baseline included when relevant
• tradeoff_summary — cost, risk, complexity, maintainability
• selected_approach — chosen option + rationale
• rejected_options_reason — concise reasons
• confidence_and_unknowns — confidence level + unresolved assumptions

Skip the innovate checkpoint only when explicitly trivial, and emit:

• checkpoint_skipped: trivial_change

Steps

1. Receive research handoff outputs (phase, inputs, decision, evidence, open_risks).
2. Run the innovate checkpoint if the change is non-trivial.
3. Decompose the approved approach into ordered, atomic tasks.
4. Map each task to exact files/paths expected to change.
5. Identify dependency ordering constraints between tasks.
6. Define validation gates and testing strategy tied to each gate.
7. Note documentation impacts, including whether updates are required for docs/File-Structure-Reference.md and docs/Project-Constraints.md.
8. Produce a handoff output following the schema below.
