Summary

Generate CSI-formatted specification sections requiring EPDs and setting maximum GWP thresholds — references ISO 14025, ISO 21930, EN 15804. Use when the user asks to write EPD requirements into a spec, set GWP limits, or "add embodied carbon requirements" to a specification.

1	# /epd-to-spec — EPD Specification Writer
2
3	Takes EPD data, GWP limits, or a materials list and generates CSI-formatted specification sections that require Environmental Product Declarations and set maximum Global Warming Potential thresholds. Output follows the same three-part CSI SectionFormat used by `/spec-writer`.
4
5	## Project Dossier
6
7	If `PROJECT.md` exists in the working directory, read it before fetching — the Decisions index may already hold GWP threshold or material choices the spec must reflect. After completing, append chosen thresholds to its Code section. Update values in place (the dossier holds current state, not history), every entry with a source and date. A GWP threshold is a decision — if one was set here, propose recording it with `/decision`. No `PROJECT.md`? Skip silently — or mention `/project-dossier init` if the user is clearly starting a project.
8
9	## Input
10
11	The user provides one or more of:
12
13	1. Material list with GWP limits — "concrete max 350 kg CO2e/m3, rebar max 1.0 kg CO2e/kg"
14	2. EPD data from the sheet — "use the EPDs I saved to set thresholds"
15	3. Comparison report — "use the lowest GWP from my last comparison as the max"
16	4. LEED target — "we're pursuing LEED v4.1 MRc2 Option 2"
17	5. Verbal description — "write EPD requirements for a ground-up office, concrete and steel structure, curtain wall"
18	6. Project type — helps determine which CSI divisions need EPD language
19
20	If the user invokes the skill without input, ask:
21
22	1. What materials need EPD requirements? (paste a list, reference the sheet, or describe the project)
23	2. Do you have specific GWP thresholds, or should I use published industry baselines (cited with named source and publication year)?
24
25	## CSI Divisions Where EPDs Are Most Common
26
27	Map materials to the correct division. EPD requirements are most relevant for structural, envelope, and interior finish materials:
28
29	\| Division \| Title \| Common EPD Products \|
30	\|----------\|-------\|-------------------\|
31	\| 03 30 00 \| Cast-in-Place Concrete \| Ready-mix concrete \|
32	\| 03 40 00 \| Precast Concrete \| Precast panels, structural precast \|
33	\| 03 41 00 \| Precast Structural Concrete \| Precast beams, columns \|
34	\| 05 12 00 \| Structural Steel Framing \| Hot-rolled steel, HSS \|
35	\| 05 21 00 \| Steel Joist Framing \| Open web steel joists \|
36	\| 05 31 00 \| Steel Decking \| Composite floor deck, roof deck \|
37	\| 05 50 00 \| Metal Fabrications \| Miscellaneous metals, rebar \|
38	\| 06 10 00 \| Rough Carpentry \| Dimensional lumber, engineered wood \|
39	\| 06 17 00 \| Shop-Fabricated Structural Wood \| Glulam, CLT, LVL \|
40	\| 07 21 00 \| Thermal Insulation \| Mineral wool, XPS, EPS, spray foam \|
41	\| 07 27 00 \| Air Barriers \| Fluid-applied, sheet membranes \|
42	\| 07 42 00 \| Wall Panels \| Metal wall panels, ACM \|
43	\| 07 54 00 \| Thermoplastic Membrane Roofing \| TPO, PVC \|
44	\| 08 44 00 \| Curtain Wall / Glazing \| Aluminum curtain wall, IGUs \|
45	\| 09 21 00 \| Plaster and Gypsum Board \| Gypsum board, joint compound \|
46	\| 09 30 00 \| Tiling \| Porcelain, ceramic tile \|
47	\| 09 51 00 \| Acoustical Ceilings \| ACT, mineral fiber \|
48	\| 09 65 00 \| Resilient Flooring \| LVT, rubber, linoleum \|
49	\| 09 68 00 \| Carpeting \| Carpet tile, broadloom \|
50	\| 32 12 00 \| Asphalt Paving \| HMA, WMA \|

52	## Spec Generation Workflow
53
54	### Step 1: Parse and classify materials
55
56	Read the user's input and build an inventory:
57
58	- Material/product — as provided
59	- CSI division and section number — mapped from the material type
60	- GWP threshold — user-provided limit, EPD sheet value, or industry baseline
61	- Declared unit — must match the unit used in the GWP threshold
62
63	If the user provided EPD sheet data or a comparison report, extract the GWP values and declared units from there.
64
65	If no GWP thresholds are specified, a published industry-average baseline may be used only when you can cite its named source and publication year (per the GWP Baseline Policy below) — always flag such thresholds `[VERIFY THRESHOLD]`. If no citable baseline is available, do not use approximate from-memory numbers. Instead, ask the user:
66
67	"I need GWP thresholds to write the spec. You can provide them by:
68	1. Sharing an EPD — I'll extract the GWP value and declared unit
69	2. Using `/epd-research` — I'll find EPDs for your material categories
70	3. Using `/epd-compare` — compare products and pick a threshold from the results
71	4. Stating a number — e.g., 'concrete max 350 kg CO2e/m3'
72
73	**We're working on EC3 API integration that will automate baseline lookups — for now, provide an
