Propose Subgoal Decomposition Plans

Use this skill when the agent has enough context to propose several viable decomposition plans.

Input Contract

Read:

• the current target theorem or branch goal
• relevant immediate_conclusions, toy_examples, and counterexamples
• relevant failed_paths and branch_states
• recent search results and useful references from events

Procedure

1. Gather the current information that materially constrains the problem: useful examples, failed claims, known obstructions, and relevant search results.
2. Propose materially different decomposition plans.
3. For each plan, state:

• the main idea of the plan
• the ordered subgoals
• why this plan is plausible given the current information
• which earlier failures or counterexamples it tries to avoid

1. Hand each plan to $direct-proving for a quick screening pass.

Output Contract

Append one record per plan to subgoals:

{
  "plan_id": "...",
  "record_type": "decomposition_plan",
  "goal": "...",
  "plan_summary": "...",
  "subgoals": ["..."],
  "motivation": ["..."],
  "uses_information_from": {
    "examples": ["..."],
    "counterexamples": ["..."],
    "key_failures": ["..."],
    "search_results": ["..."]
  },
  "status": "proposed|screening|screened|selected|failed|solved",
  "branch_id": "optional"
}

Also append an events record summarizing the new plan set.

Failure Logging

If the agent cannot yet propose meaningful decomposition plans, append an events record with:

• event_type="decomposition_plans_not_ready"
• the missing information
• the blockers that prevent proposing plans
