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.

What it costs to keep this loaded
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 | $0.00064 | $0.02918 |
| Opus 5 | $0.00032 | $0.01459 |
| Sonnet 5 | $0.00013 | $0.00584 |
| Haiku 4.5 | $0.00006 | $0.00292 |
Grade A, and why
epd-research scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 210 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/as:epd-research — EPD Research
Harness note: use
/as:<skill>on Claude Code and$<skill>on Codex. Resolve<skill-root>as the directory containing this loadedSKILL.mdand<plugin-root>as the plugin root that containsskills/, and use equivalent native tools when host tool names differ.
Receives a brief describing a material or product category, searches the web for matching EPDs (Environmental Product Declarations), and returns a curated shortlist sorted by environmental impact. The shortlist is file-free by default; selected EPDs are persisted only on explicit request.

Step 1: Take the Brief
The user describes what they need EPDs for. A brief can be loose or specific:
Loose:
"I need concrete EPDs"
Specific:
"Looking for ready-mix concrete EPDs, 4000-5000 PSI, plants within 500 miles of NYC, GWP under 350 kg CO2e/m3"
What to capture from the brief
Extract as many of these as the user provides. Don't ask for fields they didn't mention — work with what you have.
| Field | Examples |
|---|---|
| Material/product | Ready-mix concrete, structural steel, mineral wool insulation, carpet tile |
| CSI division | Division 03, Division 09, "all structural materials" |
| Performance specs | 4000 PSI, R-21, Class A fire rating |
| Geographic preference | Plants near NYC, manufactured in North America, European suppliers ok |
| GWP target | Under 350 kg CO2e/m3, below industry average, lowest available |
| Manufacturers | "Include Holcim and CEMEX", "no imported steel" |
| EPD type | Product-specific only, industry-average ok |
| Standard | EN 15804+A2, ISO 21930 |
| Certification | LEED v4.1 eligible, third-party verified |
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.

epd-research is a skill published in the GitHub repository AlpacaLabsLLC/skills-for-architects (353 stars, last pushed 8d ago), licensed MIT. It adds 64 tokens to every session and 2,918 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.
