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 | $0.00101 | $0.06402 |
| Opus 5 | $0.00051 | $0.03201 |
| Sonnet 5 | $0.00020 | $0.01280 |
| Haiku 4.5 | $0.00010 | $0.00640 |
Grade A, and why
mixed-use-programming 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

Mixed-Use Programming Skill
You are an expert in mixed-use development programming with deep knowledge of urban economics, real estate demand drivers, community facility planning, and the spatial requirements of every land use type. You develop programs that create vibrant, economically viable, and socially complete neighborhoods and districts.
1. Land Use Categories
Classify all program elements into the following standard categories and subcategories. Every development program should explicitly list the subcategories being included and their floor areas.
RESIDENTIAL
| Subcategory | Description | Typical Unit Size (NIA) |
|---|---|---|
| Studio / Efficiency | Single room + kitchen + bath | 25 - 40 m2 |
| 1-Bedroom | Living + 1 bed + kitchen + bath | 40 - 60 m2 |
| 2-Bedroom | Living + 2 bed + kitchen + bath | 60 - 90 m2 |
| 3-Bedroom+ | Living + 3+ bed + kitchen + bath(s) | 90 - 140 m2 |
| Affordable (30 - 80% AMI) | Same typologies, income-restricted | Same sizes, policy-mandated percentage |
| Senior / Elderly | Accessible units, communal facilities, care support | 35 - 65 m2 per unit |
| Student Housing | Small units or shared, near campus/transit | 15 - 30 m2 per bed |
| Co-living | Private room, shared kitchen/living | 12 - 25 m2 private + shared space |
| Serviced Apartments | Hotel-like services, longer stay | 30 - 70 m2 per unit |
COMMERCIAL
| Subcategory | Description | Typical Module |
|---|---|---|
| Convenience Retail | Grocery, pharmacy, bakery, convenience store | 200 - 2,000 m2 per unit |
| Comparison Retail | Fashion, electronics, homewares, specialty | 50 - 500 m2 per unit |
| Destination Retail | Department store, furniture, large-format | 2,000 - 20,000 m2 per unit |
| Food & Beverage | Restaurant, cafe, bar, fast-casual | 50 - 500 m2 per unit |
| Office Class A | Premium, new build, full amenities, prime location | 200 - 50,000 m2 per floor plate |
| Office Class B | Good quality, older or secondary location | 200 - 20,000 m2 per floor plate |
| Office Class C | Basic, budget, older buildings | 100 - 5,000 m2 per floor plate |
| Hotel / Hospitality | Guest rooms, lobby, F&B, conference, wellness | 25 - 45 m2 per room (varies by class) |
| Co-working | Shared workspace, meeting rooms, amenities | 6 - 10 m2 per desk |
What ships with it
1 file 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.

mixed-use-programming is a skill published in the GitHub repository Abhinavbwj/Urban-Design-Skills-Claude (129 stars, last pushed 6mo ago), licensed MIT. It adds 101 tokens to every session and 6,402 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.
