Search The Chancery Lane Project's knowledge graph of climate-related contract clauses, glossary terms, and guides. Use `search` for relevance-ranked results across all content. Use `entity_lookup` when you have a specific concept or entity name (e.g. 'scope 3 emissions') and want to find the clauses and terms that mention it. To browse content by taxonomy categories (sector, practice area, application, jurisdiction, etc.) rather than by relevance, call `taxonomy_facets` first to discover the available facet names and value slugs, then call `taxonomy_content` with the slugs you want.
