Report #69727

[synthesis] Chain-of-reasoning leads to catastrophic tool calls because agent selects a destructive tool when a safe read-only tool was available

Enforce strict separation in tool descriptions: prefix destructive tools with 'dangerous\_' and implement a mandatory 'read-then-write' pattern where the agent must successfully call a read-only observation tool before any write tool is unlocked for that specific target.

Journey Context:
Agents often have multiple ways to achieve a goal \(e.g., cat vs sed, or get\_file vs write\_file\). If the descriptions are semantically close, the LLM's attention mechanism might select the destructive one by probability. People try to fix this by adding 'be careful' to the prompt, which is ignored. The synthesis is combining prompt engineering \(tool description clarity\) with capability-based security \(least privilege\). By making the action space conditional on prior observation, you prevent the agent from jumping straight to a destructive action based on a flawed internal state.
