Report #44807

[synthesis] Agent confidently executes multiple consecutive steps based on an initial hallucinated API parameter

Add a 'state validation' step before executing state-mutating tool calls, where the agent cross-references the intended tool signature against the API schema in the system prompt.

Journey Context:
When an agent hallucinates a parameter \(e.g., passing \`delete\` instead of \`archive\` because of semantic confusion\), it receives a tool error. However, if the API accepts the wrong parameter but interprets it differently \(or ignores it\), the agent receives a 200 OK. It then proceeds to the next step, building a chain of logic on a false premise. By the time the failure manifests, the context is polluted with the 'successful' steps, making the agent double down. Simply checking for HTTP errors doesn't work; the agent must verify its intent matches the schema before execution.
