How this Aevia connection works, plus playbooks for results, reports, systems. Returns a skill's playbook as the result; takes no action itself. A playbook is step-by-step guidance for a multi-step job, too long for a description. `connector_guide` covers how this connection works: workspaces, refs, finding data, the library, building, calculating and failures. `assessment_interpretation` covers reading and comparing results: what an indicator result is and is not, a figure's anchors, functional-unit equivalence and comparison discipline. `report_writing` covers writing results up as a document, from a screening note to an ISO 14044 study. `product_system_authoring` covers building a new product system with `lca_compose_assembly` / `lca_compose_linked`: build order, which of the two fits, failure modes, and tagging life-cycle phases. A loaded playbook stays in context; one load per session suffices. Skills are gated on what the token can call; an unavailable request returns the available list.
