/as:epd-to-spec — EPD Specification Writer

Harness note: use /as:<skill> on Claude Code and $<skill> on Codex. Resolve <skill-root> as the directory containing this loaded SKILL.md and <plugin-root> as the plugin root that contains skills/, and use equivalent native tools when host tool names differ.

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 /as:spec-writer.

EPD fields follow schema/epd-schema.md. Accept pasted structured values, direct handoffs from /as:epd-parser or /as:epd-compare, or a validated project-local epd-library.csv; do not require a library.

Project context

If PROJECT.md exists in the working directory, read it before fetching, then scan decisions/*.md directly for GWP thresholds or material choices the spec must reflect. After completing, offer chosen thresholds to /as:project update for its Code section, each with a source and date. If a threshold was chosen here, propose /as:project record-decision. No PROJECT.md? Skip silently — or mention /as:project init if the user is clearly starting a project.
