- Workflow owner:
- Business sponsor:
- Engineering owner:
- Security reviewer:
- Review date:
- Intended users:
- Desired outcome:
- Explicit exclusions:

## 2. Workflow boundary
- Trigger:
- Inputs and their classifications:
- Expected outputs:
- Human decision points:
- Allowed actions:
- Actions requiring explicit approval:
- Stop conditions:

## 3. Requirements register
| ID | Requirement | Source | Owner | Verification method | Status |
|---|---|---|---|---|---|
| REQ-001 | | | | | |

Write measurable acceptance criteria. Record unresolved questions rather than assuming an answer.

## 4. Knowledge and memory
| Source or retained information | Owner | Permitted use | Access policy | Freshness / retention | Removal process |
|---|---|---|---|---|---|
| | | | | | |

## 5. Tools, skills, and harness
| Capability | Version | Workflow step | Required access | Approval rule | Owner |
|---|---|---|---|---|---|
| | | | | | |

Describe model invocation, tool routing, state transitions, checkpoints, retries, and recovery.

## 6. Operating cost assumptions
Use cost-assumptions.csv alongside this brief. Define a volume window before comparing scenarios.
- Monthly workflow executions:
- Model input tokens per execution:
- Model output tokens per execution:
- Retrieval and tool calls per execution:
- Expected retry multiplier:
- Review minutes per execution:
- Infrastructure and retention assumptions:

Estimate each driver as volume × unit cost, after converting token pricing to the same unit. Review time cost is total hours × assumed hourly cost. Keep fixed and variable costs separate. Record currency and the date of every rate assumption; these templates do not supply vendor prices.

## 7. Threat and feasibility review
- Threat scenarios:
- Affected assets:
- Planned controls:
- Control verification:
- Unresolved concerns:
- Required decisions:

## 8. Planning decision
- Decision owner:
- Decision and date:
- Accepted scope:
- Conditions:
- Open questions, owners, and due dates:
- Next review:

Keep this brief connected to the design specification, evaluation plan, and release review.
