entity_lookup
ClaudeFind TCLP content (clauses, glossary terms, guides) associated with a named concept. Unlike search, this performs a deterministic name match against Entity nodes in the knowledge graph rather than a relevance-ranked semantic search. Use it when you have a specific term or concept (e.g. "scope 3 emissions", "net zero") and want to retrieve every clause or glossary entry that explicitly references it. Args: name: The entity or concept name to look up (exact match, case-insensitive). limit: Maximum number of results to return (1–50). include_full_text: Include each hit's full body text (Markdown). Off by default — bodies are large; request only when you need the content, and prefer a small limit when you do. Returns: JSON with "meta" and "results" where each hit includes the source content node and the entity names that matched. Each hit's "references" lists the instruments it cites: pass a reference's work_id to get_legal_resource for details. A reference's edge (governs, references, describes) says how the content relates to the instrument; it is not a statement of the instrument's legal effect. If meta.degraded contains "lrsf", references could not be loaded: do not conclude that a hit cites no instruments.
find_legal_resources
ClaudeFind the laws, regulations, standards, frameworks and guidance that TCLP content refers to. This is not a general legal database: it holds only the instruments that TCLP clauses, guides and glossary terms cite. Status "stub": identity confirmed, metadata minimal; a null or empty field means not yet recorded, not that it does not apply. On a stub, nature may be an unreviewed inference, and is often null. Do not fill in missing fields from your own knowledge, and do not state an instrument's legal effect. A filter on nature, sector or bindingness excludes works where that field is not recorded. Most works do not record these yet, so an empty result does not mean that TCLP content cites no such instrument; prefer query or jurisdiction. Args: query: Case-insensitive substring match on name and aliases (e.g. "CSRD"), at most 200 characters. An exact name or alias match ranks first. nature: Any of "legislation", "regulation", "standard", "framework", "guidance". jurisdiction: Jurisdiction slugs, matched exactly: lower-case letters, digits and hyphens (e.g. "european-union"). Get valid values from taxonomy_facets(scope="legal_resource"). sector: Sector slugs, matched exactly: lower-case letters, digits and hyphens. Get valid values from taxonomy_facets(scope="legal_resource"). bindingness: Any of "binding", "comply_or_explain", "voluntary", "depends". Each list filter takes at most 20 values. limit: Maximum results (1–100, default 20). offset: Result offset for paging (0–10000, default 0). Returns: JSON with "meta" (total_available, limit, offset) and "results" (one entry per instrument, with work_id for get_legal_resource and citing_count).
get_legal_resource
ClaudeGet one law, regulation, standard, framework or guidance, and the TCLP content citing it. Versions are not tracked yet, so every citation has staleness: "unpinned": the content cites the instrument without naming a version. There is no description yet; do not supply one from your own knowledge, and do not state the instrument's legal effect. Args: work_id: The instrument's work_id, from find_legal_resources or from a search result's "references". citing_limit: Maximum citing content items to return (1–100, default 20). Returns: JSON with "resource", "citing" (each with id, title, url, content_type, edge, staleness) and "citing_total". edge (governs, references, describes) says how the content relates to the instrument; it is not a statement of the instrument's legal effect.
search
ClaudeSearch the TCLP knowledge graph using fusion search (semantic + BM25). Args: query: Free-text search query (max 1000 characters). node_type: Content scope — "tclp" (clauses, glossary terms, guides) or "all". Laws, regulations, standards and frameworks are not searchable here: use find_legal_resources. limit: Maximum number of results to return (1–50). rerank: Whether to apply RRF reranking when combining graph and text results. include_full_text: Include each hit's full body text (Markdown). Off by default — bodies are large; request only when you need the content, and prefer a small limit when you do. Returns: JSON with "meta" (totals, timing) and "results" (ranked hits with title, url, content_type, scores, optionally relationships_text, related and full_text). Each hit's "references" lists the instruments it cites: pass a reference's work_id to get_legal_resource for details. A reference's edge (governs, references, describes) says how the content relates to the instrument; it is not a statement of the instrument's legal effect. If meta.degraded contains "lrsf", references could not be loaded: do not conclude that a hit cites no instruments.
taxonomy_content
ClaudeList TCLP content (clauses, guides) or legal resources filtered by taxonomy facet=value. Multi-facet filters are combined with AND. Call taxonomy_facets first to learn which facet names and slugs exist; using a name not in that list returns a 400. Args: filters: Mapping of facet name to value slug, e.g. {"sector": "real-estate", "practice_area": "commercial"}. Each facet may appear at most once. scope: clause (ClauseName only), guide (Guide only), legal_resource (laws, regulations, standards and frameworks; facets jurisdiction and sector only), or all (clauses and guides, the default). limit: Maximum results to return (1–100, default 25). offset: Result offset for paging (default 0). sort: title, date_published_desc, or date_modified_desc. Returns: JSON with "meta" (totals, scope, filters echoed back) and "results" (each hit has id, url, title, content_type, dates, and a facets map of all taxonomy arrays on the node). content_type is clause, guide or legal_resource, the same values that search returns.
taxonomy_facets
ClaudeList taxonomy facets and their value slugs across TCLP content. Facets are taxonomy categories like sector, practice_area, application, and jurisdiction. Each facet returns the list of slugs that actually appear on the graph, with counts. Use this to discover the vocabulary, then call taxonomy_content with chosen slugs. Args: scope: Which labels to include — clause (ClauseName only), guide (Guide only), legal_resource (laws, regulations, standards and frameworks; facets jurisdiction and sector only), or all (clauses and guides, the default). Returns: JSON with "meta" and "facets". Each facet has name, applies_to (list of Neo4j labels carrying it), and values (list of {slug, count}, sorted by count desc).
