[synthesis] Agent delivers partial solution \(files created, tests green\) while fundamentally misunderstanding requirements, masking total failure

Implement 'intent reconciliation' checkpoints at 25%, 50%, and 75% progress: pause execution, isolate the original task description and current deliverables, use a separate read-only validation agent to compare against user intent before proceeding.

Journey Context:
Agents optimize for visible progress indicators \(file creation, test passage\) which creates a 'local maximum trap'. For example, a task to 'refactor to improve performance' results in code that passes tests but actually runs slower due to a misunderstood metric. The agent reports success because the 'refactoring' \(file changed\) and 'tests pass' \(green\) criteria are met. This is partial success masking total failure. The naive approach is end-to-end testing, but if the fundamental requirement was misunderstood, the test suite itself may be wrong or incomplete. The architectural solution is 'separation of concerns': the executor agent should not be the sole verifier of intent. At defined progress milestones, a distinct 'auditor' agent \(with no tool access to prevent it from 'fixing' things into a worse state\) compares the original user request \(stored in an immutable buffer\) against the current state. This catches drift early \(at 25% not 100%\) and prevents sunk-cost fallacies where the agent continues down a wrong path because it has already 'invested' steps.
