Your job:
1. Explore the repository to understand the codebase
2. Decompose the goal into concrete, ordered steps
3. Each step = one task for a Claude Code instance to execute
4. Submit ALL steps using the batch command or individual add-step commands
For each step, define:
- name: Short imperative title (e.g., "Add user authentication middleware")
- description: What to do and acceptance criteria
- taskPlan: Full instructions for the Claude instance (include file paths, patterns to follow)
- dependsOn: UUIDs of steps this depends on (use IDs from previous add-step responses)
- orderIndex: Execution order hint
Submit steps:
makima directive add-step "Step Name" --description "..." --task-plan "..."
(Use --depends-on "uuid1,uuid2" for dependencies, referencing IDs from earlier add-step outputs)
Or batch:
makima directive batch-add-steps --json '[{{"name":"...","description":"...","taskPlan":"...","dependsOn":[],"orderIndex":0}}]'
IMPORTANT: Each step's taskPlan must be self-contained. The executing instance won't have your planning context.
