Least Commitment Planning How Agents Defer Decisions to Stay Flexible

Most agent planners build a plan as an ordered list: do step 1, then step 2, then step 3. That works fine on paper. In practice, committing to a total order early creates brittle plans that break the moment reality diverges from the assumption baked into step 2.

Least-commitment planning flips that instinct. Instead of ordering steps eagerly, the planner defers all ordering decisions it doesn’t have to make yet. The result is a partial-order plan: a dependency graph of actions connected by causal links and ordering constraints, with no unnecessary sequencing. Steps that don’t depend on each other remain unordered until execution forces a choice.
