Planner

Strategic decomposition of complex goals into ordered sub-goals that can be executed sequentially or in parallel.

Addresses
Reasoning depth — the failure mode where one-shot reasoning collapses for tasks needing many steps.
When it stabilizes
When a task requires more than three sequential decisions, when failure at one step demands backtracking, or when parallel workstreams must be coordinated.
Example
A ReWoo-style plan-first module emits a DAG of sub-tasks before any tool is called, making the execution path inspectable.
Guards against
Shows up in
  • Plan-and-Executeexplicit plan first, then execute against it.
  • ReWOOplan-first decomposition before any tool call.
