Report #90055

[gotcha] Dynamically generating tool descriptions from untrusted data

Hardcode or strictly sanitize tool descriptions provided to the LLM; never allow external data to define tool schemas or descriptions.

Journey Context:
In ReAct-style agents, the LLM chooses tools based on their descriptions. If an attacker can manipulate a tool's description \(e.g., in a plugin registry\), they can make the LLM choose the wrong tool or pass malicious arguments.
