Step 4: Weekly Plan

Refine a meal plan iteratively until it meets quality criteria.

Goal

Use type: loop to generate and refine a meal plan until variety requirements are satisfied.

The Workflow

Update recipe.yaml:

# yaml-language-server: $schema=../../schemas/workflow.schema.json
name: weekly-plan
description: Generate a weekly meal plan with iterative refinement

inputs:
  - name: pantry_file
    type: string
    default: "pantry.txt"
    description: Path to pantry inventory file

  - name: diet
    type: string
    default: "balanced"
    description: Dietary preference

steps:
  - id: read_pantry
    name: Read Pantry Inventory
    file.read: "{{.inputs.pantry_file}}"

  - id: refine_plan
    name: Generate and Refine Plan
    type: loop
    max_iterations: 3
    until: "steps.check.passes == true"
    steps:
      - id: generate
        name: Generate Plan
        type: llm
        model: strategic
        prompt: |
          Available ingredients:
          {{.steps.read_pantry.content}}

          {{if .loop.history}}
          Previous attempt feedback:
          {{.loop.history.check.feedback}}

          Improve the plan based on this feedback.
          {{else}}
          Generate a {{.inputs.diet}} meal plan for Monday through Sunday.
          {{end}}

          For each day, create breakfast, lunch, and dinner.
          Don't repeat main proteins on consecutive days.

      - id: check
        name: Check Variety
        type: llm
        model: fast
        output_schema:
          type: object
          properties:
            passes:
              type: boolean
            feedback:
              type: string
        prompt: |
          Review this meal plan for variety:
          {{.steps.generate.response}}

          Check:
          1. No main protein repeated on consecutive days
          2. Breakfast items vary throughout the week

          Return {"passes": true} if requirements are met.
          Otherwise return {"passes": false, "feedback": "specific issues"}.

outputs:
  - name: weekly_plan
    type: string
    value: "{{.steps.refine_plan.generate.response}}"

    format: markdown

Run It

conductor run recipe.yaml

The loop runs until check.passes is true or 3 iterations complete.

What You Learned

• Loops - Use type: loop for iterative refinement
• until - Termination condition evaluated after each iteration
• max_iterations - Safety limit to prevent infinite loops
• loop.history - Access previous iteration outputs to improve results
