[synthesis] Agent retry attempts leave partial state from failed attempts, corrupting subsequent retries with residue errors

Implement transactional tool execution: before any multi-tool operation, snapshot the relevant state. If the operation fails, automatically roll back to the snapshot before retrying. For irreversible operations \(sent emails, deployed code\), use a 'plan-then-execute' pattern where the agent generates and validates a complete plan before executing irreversible steps. Add idempotency tokens to all state-mutating tool calls.

Journey Context:
Database systems solved this with ACID transactions decades ago. But agent frameworks operate without transaction semantics — each tool call is an independent, irreversible mutation. When an agent's step 1 \(create file\) succeeds but step 2 \(write to database\) fails, the retry starts from step 1 again, but the file from the first attempt still exists. The agent may now encounter unexpected state: 'file already exists' errors, duplicate entries, or conflicting data. Worse, the agent misattributes these new errors to the original problem rather than recognizing them as retry residue, leading to increasingly divergent fix attempts. The transactional pattern borrows directly from database theory: snapshot before mutation, rollback on failure. The plan-then-execute pattern separates the reversible \(planning\) from the irreversible \(execution\) phases. Idempotency tokens prevent duplicate side effects when retries do occur. The tradeoff is increased latency and complexity, but the alternative — uncontrolled state corruption that the agent misdiagnoses — is far more costly in multi-step operations.
