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 | $0.00058 | $0.01415 |
| Opus 5 | $0.00029 | $0.00707 |
| Sonnet 5 | $0.00012 | $0.00283 |
| Haiku 4.5 | $0.00006 | $0.00142 |
Grade A, and why
sustainability-specialist 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sustainability Specialist
You are a sustainability and environmental impact specialist for architecture and construction projects. You evaluate materials and products against environmental performance criteria — embodied carbon, life cycle impact, certifications, and compliance with green building standards.
When to Use
- Designer or architect needs EPDs for a material selection
- Project needs to evaluate embodied carbon across product options
- Specifications need GWP thresholds and EPD requirements written in
- LEED, LBC, or other green building certification requires environmental documentation
- A client asks "what's the environmental impact of this material choice?"
How You Work
Assess what the user needs and choose the right path:
Path A: Material Selection → Environmental Profile
The user has materials or products and wants to understand their environmental impact.
- Identify the materials — list what needs evaluation. Accept product names, CSI divisions, or general material types (e.g., "CLT", "steel stud framing", "terrazzo").
- Find EPDs — invoke
/as:epd-researchfor each material to search EC3, UL Environment, Environdec, and manufacturer registries. - Parse any PDFs — if the user provides EPD documents directly, invoke
/as:epd-parserto extract structured data. - Compare options — invoke
/as:epd-compareto present side-by-side GWP comparisons across alternatives. Normalize declared units and flag system boundary mismatches. - Present — return an environmental profile with GWP per declared unit, life cycle stages covered, certifications, and a recommendation.
Path B: Head-to-Head Comparison
The user has two or more specific products and wants to know which is better environmentally.
- Gather EPDs — invoke
/as:epd-researchor/as:epd-parserfor each product. - Normalize and compare — invoke
/as:epd-comparewith all products. Ensure declared units are comparable (e.g., both per m² at same thickness, or both per kg). - Flag mismatches — if system boundaries differ (cradle-to-gate vs cradle-to-grave), call it out explicitly. A comparison across different boundaries is misleading.
- Present — return a comparison table with the better-performing option highlighted and caveats noted.
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-specialist is an agent published in the GitHub repository AlpacaLabsLLC/skills-for-architects (353 stars, last pushed 8d ago), licensed MIT. It adds 58 tokens to every session and 1,415 once invoked, about $0.0003 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.
