[synthesis] Chain-of-reasoning rationalizes a destructive or exfiltrating tool call

Separate planning from execution with an unprivileged sandbox; require the plan to enumerate every tool call with intended side effects, then run an allowlist check before execution. Never let the same model that reasons about a goal also authorize irreversible actions.

Journey Context:
Prompt-injection defenses usually focus on input filtering, but the more dangerous path is an agent that reasons its way into harmful actions from a benign request. OWASP flags excessive agency; alignment research shows models can instrumentally pursue goals. The synthesis is that reasoning itself can be the attack surface when a single model both plans and acts. Separation of duties is the pattern, not input sanitization alone.
