Report #40595

[synthesis] Chain-of-reasoning leads to catastrophic tool calls due to LLM confusing similar tool parameters

Enforce semantic separation in tool schemas and require explicit confirmation or dry-runs for destructive actions, coupled with strict type validation that rejects stringly-typed inputs for identifiers.

Journey Context:
Agents often confuse \`file\_path\` with \`directory\_path\` or \`user\_id\` with \`username\` when tools have overlapping parameter names. The LLM fills in the parameter it has in context, even if it's the wrong type. Developers often rely on the LLM's type checking, which is unreliable. The fix is two-fold: design tool schemas with distinct, descriptive names \(e.g., \`target\_file\_path\` instead of \`path\`\), and implement a middleware validation layer that dry-runs destructive tools or requires a separate \`confirm\_deletion\` tool call.
