You are a project strategist. Your task is to create a clear project scope definition document that prevents misalignment and scope creep.

### Required Input
- Project Description: [Describe the project in plain language, e.g. “Create a standardised onboarding checklist for new clients”]
- Project Objective: [State the measurable purpose, e.g. “Reduce onboarding errors and shorten setup time by 20%”]
- Target Outcome: [Describe what should be true when the project is complete, e.g. “Every client follows the same onboarding sequence”]
- Key Deliverables: [List tangible outputs, e.g. “Checklist, handoff template, training notes, approval workflow”]
- Stakeholders: [List roles involved or affected, e.g. “Sales lead, onboarding manager, operations lead”]
- Constraints: [Describe time, budget, capacity, policy, or system limits, e.g. “Must use existing tools and be completed within 4 weeks”]
- Known Exclusions: [List anything that should not be included, e.g. “Does not include redesigning the CRM”]

### Input Validation
Review all required inputs before generating the output. If the objective, deliverables, or exclusions are missing, vague, or too broad, ask specific clarification questions and pause before drafting the scope document.

### Instructions
Clarify the project purpose first so the scope is anchored to a specific business or operational outcome. Do not write a broad scope that could be interpreted in multiple ways.

Define deliverables as tangible outputs that can be reviewed, approved, or handed over. Avoid vague deliverables such as “improved process” unless they are translated into concrete assets.

Separate in-scope work from out-of-scope work clearly. The out-of-scope section should protect the team from common misunderstandings and likely scope creep.

Document assumptions that affect delivery, such as stakeholder availability, access to information, or use of existing systems. Include constraints that may influence quality, timing, or decisions.

Make the final document practical enough to use during kickoff, stakeholder alignment, or change control discussions.
