## Trigger — use this when

- Use this before delegating a bounded piece of work to an AI agent.

## Failure — what goes wrong without it

The agent starts activity without understanding the outcome, boundaries, or proof of completion.

## Objective — what it produces

The agent can state the requested result, its boundaries, and how completion will be checked.

## The Practice

### 1. State the outcome

Tell the agent what must be true when the work is finished.

*Why:* This prevents activity from being mistaken for completion.

### 2. Name the boundaries

State what the agent may change and what must remain untouched.

*Why:* This prevents useful work from becoming an unbounded rewrite.

### 3. Define the proof

Give the agent an observable completion check before it starts.

*Why:* A verifiable finish is stronger than a claim that the task is done.

## Limits — do not use this when

- Do not use it as a substitute for an exploratory conversation when the outcome is still unknown.
- The briefing guides execution; it does not grant authority beyond the current user's request.

## Verify — evidence that it helped

- The agent can repeat the outcome and completion test before starting.
