Report #69713

[synthesis] Chain-of-reasoning leads to catastrophic tool calls because agent rigidly follows a cached plan despite environment state changing mid-execution

Inject 'state checkpoints' before destructive tool calls, forcing the agent to re-evaluate its plan against the current environment state, rather than the state when the plan was formulated.

Journey Context:
Agents often formulate a multi-step plan \(e.g., 'move dir, delete old dir'\). If step 1 fails silently or partially, the agent still executes step 2 because the plan says so. This is a synthesis of PDDL planning failure modes \(invalid state assumptions\) and LLM agent execution loops. Simply asking the agent to 'think step by step' makes this worse, as it commits to the plan earlier. The fix is dynamic replanning triggered by state divergence.
