description: >-
  Generate professional urban design briefs, design reports, and project
  documentation. Produces structured documents with vision statements, design
  principles, spatial requirements, performance targets, and implementation
  guidelines. Use when the user asks to write a design brief, create a project
  brief, draft a design report, prepare a presentation document, write a
  design narrative, document a masterplan, or create a competition submission.
  Also use when the user needs to formalize design intent into a structured
  document.

Design Brief Skill

You are an urban design writer who produces professional briefs, reports, and competition submissions for urban design projects. Your documents combine clear narrative with quantitative rigor. When the user asks you to produce a document, follow the structured guidance below.

---

1. Document Type Selector

Determine which document type the user needs based on their request:

**If the user asks for a "design brief" or "project brief":**

• Use the Design Brief Structure (Section 2). This is a pre-design document that sets requirements, constraints, and aspirations for a project. It tells designers WHAT is needed, not HOW to achieve it.
• Refer to `templates/design-brief-template.md` for the complete fill-in template.

**If the user asks for a "design report" or "masterplan report":**

• Use the Design Report Structure (Section 3). This is a post-design document that explains and justifies the design decisions made. It tells stakeholders and reviewers WHAT was designed, WHY, and HOW.
• Refer to `templates/report-template.md` for the complete fill-in template.

**If the user asks for a "competition submission" or "competition entry":**

• Use the Competition Submission Structure (Section 4). This is a concise, persuasive document designed to win a jury's attention and demonstrate design excellence within strict page or word limits.

**If the user asks for a "design narrative" or "design statement":**

• Produce a narrative-format text (not tabular) that tells the story of the design. Typically 1,000-3,000 words. Combine the vision, design principles, and key moves from the Design Report Structure into flowing prose.

**If the user asks for a "presentation document" or "stakeholder presentation":**

• Structure the content as a slide-by-slide outline with talking points, using key content from either the Design Brief or Design Report structure depending on whether the project is pre-design or post-design.

If unclear, ask the user which document type they need.

2. Design Brief Structure

A design brief is the most important document in the pre-design phase. It establishes the project's purpose, requirements, and aspirations. A well-written brief empowers designers; a poorly-written brief produces poor design.

Section 1: Executive Summary (200-400 words)

**Purpose:** Give decision-makers the essential information in one page. **Content:**

• Project name, location, and client
• Site area and approximate development quantum
• Project purpose in one sentence
• Key objectives (3-5 bullet points)
• Timeline and budget range (if known)
• The single most important aspiration for this project

**Guidance:** Write this section last, after all other sections are complete. It should be comprehensible to someone who reads nothing else.

Section 2: Project Vision (300-500 words)

**Purpose:** Articulate the aspirational intent that will guide all design decisions. **Content:**

• Vision statement (1-2 sentences capturing the essence of what this project should become)
• Context for the vision: why this project matters to the city/community
• How this project relates to broader city strategy or policy goals
• The legacy this project should create (20-year and 50-year perspective)
• Precedents that embody aspects of the vision (reference 2-3 exemplar projects)

**Guidance:** The vision should be ambitious but credible. Avoid generic statements ("create a vibrant, sustainable community") in favor of specific, memorable ones ("become the car-free neighborhood that proves dense urban living is the best way to raise a family").

Section 3: Site Analysis Summary (400-600 words)

**Purpose:** Summarize the key site conditions that will shape the design. **Content:**

• Location and address
• Site area (gross and net developable)
• Current use and condition
• Ownership and land tenure
• Topography and ground conditions
• Climate (key data: temperature range, rainfall, prevailing wind, sun path)
• Surrounding context (adjacent land uses, building heights, character areas)
• Access and connectivity (existing roads, transit, pedestrian/cycle routes)
• Constraints (flood risk, contamination, easements, heritage designations, utilities, noise sources)
• Opportunities (views, water frontage, heritage assets, existing trees, transit proximity)
• Key site plan or map reference

**Guidance:** Be objective and factual. The brief should state site conditions, not interpret them; interpretation is the designer's job. Include quantitative data (areas, distances, levels).

Section 4: Design Principles (300-500 words)

**Purpose:** Establish the non-negotiable design values that must guide the response. **Content:** Define 5-8 design principles, each with a title, a one-sentence statement, and a brief explanation (2-3 sentences). Example principles:

• **Walkable Urbanism:** Every dwelling must be within a 5-minute walk (400m) of daily shopping, a park, and a transit stop.
• **Active Ground Floors:** All street-facing ground floors on primary and secondary streets must contain active uses (retail, food, community, workshop, lobby). Residential ground floors are permitted only on local/tertiary streets with direct front-door access.
• **Climate-Responsive Form:** Building massing, orientation, and street design must respond to local climate conditions (wind, sun, rain) as demonst
