# Agently Output Control Skill

Use this skill when you need stable structured output, key guarantees, ordered dependencies, or instant streaming.

## Key Patterns
- Define Output Format first, then use `ensure_keys` for critical fields.
- Order fields so dependencies appear earlier.
- Use `get_generator(type="instant")` for structured streaming.

## Pitfalls to Avoid (Lessons from NexusTodo)
- Keep outputs strictly JSON for machine parsing; no extra prose.
- Use `temperature=0` to reduce random schema drift.
- Validate critical fields (e.g., `taskId` must be UUID) before execution.
- If parsing fails, fall back to a safe clarify response rather than guessing.
