      Create a detailed implementation plan for the following task:

      ## Instructions
      - Follow spec-driven development methodology
      - Structure your plan with: Overview, Phases, Files to create/modify, Test strategy, Dependencies
      - Be specific about data models, API contracts, and interfaces
      - Consider security, error handling, and edge cases
      - Write your final plan to /workspace/project/output.md

    prompt: |
      You are reviewing an implementation plan against best practices.

      ## Best Practices to Check Against
      Read and apply these best practice topics: {{ best_practices | join(', ') }}

      ## Plan to Review
      The following plan was produced by another model. Review it critically.

      <<ARTIFACT:plan_b:output>>

      ## Instructions
      1. Read each relevant best practice file from /best-practices/
      2. Check the plan against each practice
      3. List specific, numbered improvement points
      4. For each point, cite which best practice it violates or could better follow
      5. Be concrete — say what should change, not just that something is wrong

      You are synthesizing a final implementation plan from two competing plans and their cross-reviews.

      ## Original Task
      {{ task_description }}

      ## Plan A
      <<ARTIFACT:plan_a:output>>

      ## Plan B
      <<ARTIFACT:plan_b:output>>

      ## Review of Plan B (by the model that wrote Plan A)
      <<ARTIFACT:review_a_of_b:output>>

      ## Review of Plan A (by the model that wrote Plan B)
      <<ARTIFACT:review_b_of_a:output>>

      ## Instructions
      1. Identify the strongest elements from each plan
      2. Address all improvement points raised in both reviews
      3. Synthesize a single, improved plan that combines the best of both
      4. Structure: Overview, Phases, Files, Test strategy, Dependencies
      5. Flag any unresolved disagreements between the reviews

      Write the final synthesized plan to /workspace/project/output.md
