Report #40419

[gotcha] Agent enters a loop repeatedly calling the same MCP tool with the same arguments

Implement client-side circuit breakers that track \(tool\_name, arguments\) pairs. If the exact same call is made N times consecutively, inject a system message forcing the agent to change strategy or abort.

Journey Context:
Agents often get stuck in 'retry loops' \(e.g., trying to write a file, failing due to permissions, trying again\). MCP tools are stateful, but the agent might not realize its actions are failing silently or not changing the environment. A circuit breaker is necessary because the LLM itself lacks the meta-cognition to break out of these loops naturally without external intervention.
