Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00096 | $0.05913 |
| Opus 5 | $0.00048 | $0.02957 |
| Sonnet 5 | $0.00019 | $0.01183 |
| Haiku 4.5 | $0.00010 | $0.00591 |
Grade A, and why
design-brief scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 487 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.mdfor 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.mdfor 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.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

design-brief is a skill published in the GitHub repository Abhinavbwj/Urban-Design-Skills-Claude (129 stars, last pushed 6mo ago), licensed MIT. It adds 96 tokens to every session and 5,913 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
