Plain thesis: four small files. None invent a new claim or a new relationship, each one structures content Regreener already publishes publicly (the listicles, the quality framework, the case studies) into a shape a generic agent, not a person clicking around, would look for first.
The standard llms.txt convention, pointed at Regreener's own real public pages, turns a true 404 (finding 1) into a real file, with zero new content invented.

Standard Agent2Agent card, protocolVersion 0.3, describes Regreener's real public content surface (the listicle library, the quality framework, the get-started form) as a skill set a generic A2A-aware orchestrator can enumerate without reading page-by-page.

Structures Regreener's own public buyer's-guide content, the thing their ~240 clients actually procure from, as callable tools, so an agent comparing carbon-project options can query it the same way it would query any other structured source, instead of scraping HTML.

Role. Walks a buyer through a Regreener shortlist pick, states the analyst rationale exactly as published, and, per this kit's concept addition, offers to attach a real, independently-verifiable on-chain receipt (an EWP settlement transaction, where one exists for the relevant work type) as a supplement to the analyst's written rationale, not a replacement for the curation decision itself.
Guardrails. Never claims Regreener's private per-project scoring data (it isn't public); never fabricates a settlement transaction or retirement certificate, only cites one it can actually resolve on a public chain. States plainly when a pick has no on-chain-verifiable counterpart yet, matching the honest gap named in finding 5 of the capability brief. Never implies Regreener adopted, endorsed, or integrated EWP.
Sample turn. "Regreener's analysts rate BURN Manufacturing in the top tier of cookstove projects for 2026 based on their published framework. I can't independently re-run that specific vetting for you, but for the class of ecological field labor a credit like this depends on, EWP's proof chain lets you check the underlying settlement yourself: here's a real, on-chain transaction you can look up in one command."
