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 | $0.00105 | $0.07947 |
| Opus 5 | $0.00053 | $0.03973 |
| Sonnet 5 | $0.00021 | $0.01589 |
| Haiku 4.5 | $0.00011 | $0.00795 |
Grade A, and why
sustainability-scoring 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.

Sustainability Scoring Skill
This skill provides comprehensive sustainability certification scoring for urban designs and masterplans. It covers the six major neighborhood/community-scale rating systems used globally: LEED-ND (US), BREEAM Communities (UK/Europe), WELL Community Standard (global, health-focused), Green Star Communities (Australia/NZ), CASBEE Urban Development (Japan), and Estidama Pearl Community Rating System (Middle East). The skill generates credit-by-credit scoring analyses, identifies optimization opportunities, and produces professional scorecard reports.
1. Certification System Selector
Use the following decision tree to select the appropriate certification system(s) for a given project. Geography is the primary driver, but project focus and client preference may override.
Decision Tree
START
|
|--> Where is the project located?
| |
| |--> North America (US, Canada) --> LEED-ND v4.1
| | |--> Also health-focused? --> Add WELL Community Standard
| |
| |--> United Kingdom --> BREEAM Communities
| | |--> Also health-focused? --> Add WELL Community Standard
| |
| |--> Europe (non-UK) --> BREEAM Communities (or local adaptation)
| | |--> Also health-focused? --> Add WELL Community Standard
| |
| |--> Australia or New Zealand --> Green Star Communities
| | |--> Also health-focused? --> Add WELL Community Standard
| |
| |--> Japan --> CASBEE for Urban Development
| |
| |--> Middle East (esp. Abu Dhabi, UAE) --> Estidama Pearl Community
| | |--> Abu Dhabi specifically? --> Estidama Pearl is MANDATORY
| |
| |--> Other regions --> LEED-ND (most globally recognized)
| |--> Or BREEAM International New Construction (building scale)
|
|--> Does the client have a specific certification preference?
| |--> Yes --> Use client's preferred system
| |--> No --> Use geography-based recommendation above
|
|--> Does the project seek multiple certifications?
|--> Yes --> Use Cross-Certification Comparison Matrix (Section 3) to
| identify strategies that earn credits across multiple systems
|--> No --> Focus on single system for maximum point optimization
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.

sustainability-scoring is a skill published in the GitHub repository Abhinavbwj/Urban-Design-Skills-Claude (129 stars, last pushed 6mo ago), licensed MIT. It adds 105 tokens to every session and 7,947 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.
