Identify Key Failures

Identify Key Failures

Use this skill to turn many failed attempts into reusable guidance for the next planning round.

Input Contract

Read:

• the failed decomposition plans
• direct-proving stuck points
• recursive sub-agent reports
• existing failed_paths
• relevant counterexamples and toy_examples

Procedure

1. Gather the reports from all failed plans and sub-agents.
2. List the key stuck points for each plan.
3. Identify common points across those failures:
   • recurring obstructions or counterexamples
   • decomposition patterns that keep breaking
   • search gaps or missing background facts
4. Summarize what the failures suggest for the next generation of decomposition plans.
5. Save the synthesized failure knowledge to failed_paths so later planning skills can use it.
6. After recording the failure synthesis, return control to $propose-subgoal-decomposition-plans.

Output Contract

Append to failed_paths:

{
  "record_type": "key_failures_summary",
  "failed_plan_ids": ["..."],
  "plan_failures": [
    {
      "plan_id": "...",
      "stuck_points": ["..."]
    }
  ],
  "common_failures": ["..."],
  "implications_for_next_plans": ["..."]
}

Also append an events record indicating that a new planning round is needed.

Failure Logging

If the reports are too weak to identify meaningful common failures, append an events record with event_type="key_failures_inconclusive" and state what information is still missing.
