Report #22285

[synthesis] Agent loops silently derailing on empty or 200 OK tool responses without state change

Implement state verification checks after tool execution. If a tool returns success but the intended state change is unverified, add an explicit verification step \(e.g., git status after git commit, or reading the file after writing it\) rather than trusting the tool's exit code.

Journey Context:
Agents trust tool exit codes implicitly. A file.write might succeed but write to the wrong path, or an API returns 200 but doesn't mutate state due to idempotency or a wrong payload. Without verifying the actual state, the agent's context diverges from reality, leading to confidently wrong subsequent steps. The tradeoff is extra tool calls \(cost/latency\) vs. certainty, but certainty is required to prevent silent catastrophic drift.
