Lexplorer Swiss Tax Research

Recursive hierarchical tree (kanton → categories → sources → documents). max_depth 0-3. Replaces 3-5 sequential nav_list_* calls.

nav_tree

Read the pre-generated navigation overview (_navigation.md) of a canton: categories + sources.

get_kanton_navigation_md

Find where a source/document lives in the hierarchy by name pattern. Returns canton + category + breadcrumb. Pass filter_kanton when you already know the canton — otherwise generic patterns may sort ZH out of the LIMIT 20 window.

nav_find

Read the full text of one indexed chunk plus links to its parent document (PDF and Markdown) in the Lexplorer corpus. Results include lexplorer_url (public source page) — when citing this source in an answer, use lexplorer_url as the clickable markdown link.

get_chunk_content

Read one research playbook (Markdown skill file) by name.

get_skill

Hybrid search (semantic + keyword, RRF-fused) over the indexed Lexplorer chunks. The query text is embedded via Google Vertex AI (EU region); results come exclusively from the Lexplorer corpus. Good when mixed. Results include lexplorer_url (public source page) — when citing this source in an answer, use lexplorer_url as the clickable markdown link.

search_chunks_hybrid

German full-text keyword search over the indexed Lexplorer chunks (database only, no external service). Best for exact terms (§, Art-Nr, named concepts). Results include lexplorer_url (public source page) — when citing this source in an answer, use lexplorer_url as the clickable markdown link.

search_chunks_keyword

List all 26 Swiss cantons + CH (federal) with chunk/source/doc counts from the Lexplorer tax-law index.

nav_list_kantons

List the source categories (legislation, administrative practice, doctrine, ...) indexed for one canton.

nav_list_categories

List the text chunks of a parent document.
