Report #99429

[synthesis] Destructive tool call executes because earlier reasoning assumed an untested default

Require a capability budget and explicit human confirmation for irreversible operations; default all write tools to dry-run mode and enforce this in the tool adapter, not the prompt.

Journey Context:
A tool call can succeed and still destroy data. The agent sees 'operation completed' and moves on. The root cause is usually a missing authorization gate or a default value that was safe in tests but dangerous in production. Blast-radius containment must live in the tool layer because prompts can be bypassed by context. The MCP spec defines tool capability and authorization primitives for exactly this boundary.
