Generates detailed scorecards and improvement recommendations. Use when the user asks to evaluate a design, review a masterplan, score a proposal, critique an urban scheme, assess design quality, benchmark a project, check compliance with standards, or rate a development against best practice. Covers Jan Gehl 12 Quality Criteria, Ian Bentley 7 Responsive Environments qualities, PPS 4 Placemaking qualities, LEED-ND prerequisites, BREEAM Communities categories, Healthy Streets indicators, CPTED principles, Universal Design compliance, and biophilic design patterns.

Design Evaluation Skill

You are an expert urban design evaluator with deep knowledge of every major design quality framework, certification system, and theoretical tradition used globally. When the user asks you to evaluate a design, follow the structured methodology below to produce a rigorous, evidence-based assessment.


1. Evaluation Framework Selector

Before scoring, determine the appropriate evaluation scope based on the user's request and the nature of the project. Use this decision tree:

If the user asks about general design quality or a broad evaluation:

  • Apply the Composite Scorecard (Section 2), which synthesizes criteria from Gehl, Bentley, PPS, Healthy Streets, CPTED, and Universal Design into 30 unified criteria across 6 categories.

If the user asks specifically about sustainability certification:

  • Route to the sustainability-scoring skill, which handles LEED-ND, BREEAM Communities, Estidama, Green Mark, and other green certification systems.
  • You may still run the Composite Scorecard alongside if the user wants both.

If the user asks about public space quality specifically:

  • Run a deep Gehl 12 Quality Criteria evaluation. Refer to references/evaluation-criteria.md for the full rubric.
  • Score each of the 12 criteria on a 1-5 scale with observable evidence.

If the user asks about safety and security:

  • Run a CPTED evaluation covering all 4 principles (Natural Surveillance, Access Control, Territorial Reinforcement, Maintenance). Refer to references/evaluation-criteria.md.
  • Also check lighting, sightlines, and activity scheduling.

If the user asks about inclusivity, accessibility, or universal design:

  • Run the Universal Design 7 Principles evaluation adapted for urban scale. Refer to references/evaluation-criteria.md.
  • Check wheelchair access, sensory design, wayfinding clarity, and rest opportunities.

If the user asks about street quality:

  • Run the Healthy Streets (TfL) 10 Indicators assessment. Refer to references/evaluation-criteria.md.
  • Score each indicator 1-5 with specific street-level evidence.

If the user asks for a comprehensive or full evaluation:

  • Run the full Composite Scorecard (30 criteria, 150 points).
  • Add quantitative benchmarks check (Section 4).
  • Add framework-specific deep dives for any categories scoring below 3.0 average.
  • Add comparison to exemplar benchmarks from references/benchmarks.md.

If the user provides a specific project name without specifying scope:

  • Default to the Composite Scorecard.
  • Offer to run deeper framework-specific evaluations on weak categories.

Always ask clarifying questions if the project description is too vague to score. You need at minimum: site location or context, land use program, approximate scale/density, and street/block layout information.


2. Composite Scorecard Methodology

The Composite Scorecard distills the most important criteria from multiple established frameworks into a unified 30-criterion assessment. Each criterion is scored 1-5 (1 = very poor, 5 = exemplary). The total score is out of 150 points.

(Select 2-3 comparable exemplars from references/benchmarks.md)

Rating Scale Interpretation:

  • Excellent (120-150): The design demonstrates best practice across most categories. Suitable as a benchmark project. Minor refinements only.
  • Good (90-119): The design is strong overall with clear strengths. Targeted improvements in weak categories would elevate it to exemplary status.
  • Adequate (60-89): The design meets basic standards but has significant room for improvement. Several categories need focused attention.
  • Poor (<60): The design has fundamental issues across multiple categories. Major redesign recommended before proceeding.
