Report #5026

[gotcha] Agent enters an infinite loop calling the same MCP tools with identical parameters

Enforce a strict max-turn budget, detect repeated tool-call patterns, and force the model to synthesize an answer when no new information is gained. Avoid tools whose output is fed back as input without a clear termination condition.

Journey Context:
A documented OpenClaw bug shows Kimi Code repeatedly calling read/exec with identical arguments, receiving identical results, and never emitting a final answer. Common triggers are search/browse tools returning overlapping results or file-read loops where the model keeps opening adjacent files. Without an iteration cap and a stop-and-answer rule, the agent burns quota while appearing to 'think'.
