[gotcha] Allowing unbounded recursive tool calls or tool-to-tool chaining without resource limits

Enforce a strict maximum depth for tool call chains, a global timeout for agent loops, and token budgets for tool outputs to prevent resource exhaustion.

Journey Context:
An LLM might get stuck in a loop where Tool A's output triggers Tool B, which triggers Tool A again. Or, a prompt injection might instruct the LLM to 'keep searching until you find X', causing it to paginate through an entire database via a tool, leading to API rate limits, massive token consumption, and high costs. Without hard limits on iterations, depth, and execution time, agents will happily loop until they exhaust resources.
