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 | $0.00134 | $0.07391 |
| Opus 5 | $0.00067 | $0.03696 |
| Sonnet 5 | $0.00027 | $0.01478 |
| Haiku 4.5 | $0.00013 | $0.00739 |
Grade A, and why
mobility-and-transport 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 13d 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.

Mobility and Transport Planning Skill
This skill provides a comprehensive transport and mobility planning framework for urban design at the neighborhood, district, and city scales. It draws on ITE Trip Generation (11th Edition), TfL transport assessment guidance, ITDP standards, NACTO transit street guidance, Dutch cycling infrastructure design manuals (CROW), and global best practices from cities achieving high non-car mode shares.
The goal is to ensure every urban design proposal includes a robust, multimodal transport strategy that prioritizes walking, cycling, and transit over private car use, while handling freight and servicing efficiently.
1. Transport Demand Estimation
1.1 Trip Generation by Land Use (ITE 11th Edition Basis)
Use the following rates for preliminary transport demand estimation. Rates are per unit (dwelling, 100m2 GFA, room, seat) and represent daily person-trips (all modes). Apply mode split factors (Section 2) to convert to vehicle trips.
Residential
| Type | Unit | Daily Person-Trips | AM Peak | PM Peak |
|---|---|---|---|---|
| Detached house | per dwelling | 9.4 | 0.74 | 1.00 |
| Townhouse / row house | per dwelling | 7.2 | 0.56 | 0.76 |
| Low-rise apartment (1-3 floors) | per dwelling | 6.6 | 0.51 | 0.62 |
| Mid-rise apartment (4-10 floors) | per dwelling | 5.4 | 0.36 | 0.44 |
| High-rise apartment (11+ floors) | per dwelling | 4.2 | 0.30 | 0.36 |
| Student housing | per bed | 3.6 | 0.28 | 0.32 |
| Senior housing | per unit | 3.0 | 0.20 | 0.24 |
Commercial / Office
| Type | Unit | Daily Person-Trips | AM Peak | PM Peak |
|---|---|---|---|---|
| General office | per 100m2 GFA | 11.0 | 1.56 | 1.49 |
| Medical office | per 100m2 GFA | 36.1 | 2.78 | 3.46 |
| Business park | per 100m2 GFA | 12.4 | 1.73 | 1.74 |
| Co-working / flexible | per 100m2 GFA | 14.0 | 1.90 | 1.80 |
Retail
| Type | Unit | Daily Person-Trips | AM Peak | PM Peak |
|---|---|---|---|---|
| Neighborhood retail | per 100m2 GFA | 42.7 | 1.03 | 3.75 |
| Shopping center | per 100m2 GFA | 37.8 | 0.96 | 3.41 |
| Supermarket | per 100m2 GFA | 102.2 | 3.40 | 9.48 |
| Convenience store | per 100m2 GFA | 737.0 | 33.6 | 52.4 |
| Restaurant / F&B | per 100m2 GFA | 89.9 | 0.73 | 7.49 |
What ships with it
3 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.

mobility-and-transport is a skill published in the GitHub repository Abhinavbwj/Urban-Design-Skills-Claude (129 stars, last pushed 6mo ago), licensed MIT. It adds 134 tokens to every session and 7,391 once invoked, about $0.0007 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.
