Report #6691

[agent\_craft] Agent enters infinite loop retrying failed tool calls with identical or minimally perturbed parameters

Mandate an explicit 'error analysis' reflection step before any tool retry; require the agent to output a structured delta \(what changed and why\) before executing the next tool call

Journey Context:
When a tool call fails \(API error, validation failure, execution error\), agents often implement naive retry logic—immediately retrying with the same parameters or making random perturbations \(like adding 'retry' to a query\). This creates infinite loops that waste tokens and time. The hard-won fix is architectural: enforce a mandatory reflection step. Before any retry, the agent must explicitly analyze the error message, hypothesize the root cause, and specify what will change in the next attempt. This breaks the loop and dramatically improves recovery rates by forcing cognitive engagement with the failure rather than reflexive repetition.
