Full-text search across every public Wealthsimple Help Center article. Returns a ranked list of articles with titles, URLs, snippets, labels, and section IDs. Use this whenever the user asks anything about Wealthsimple products (Trade, Invest, Cash, Crypto, Tax, registered accounts like TFSA / RRSP / FHSA, transfers, deposits, etc.) — the help center is the canonical source of truth.

List the top-level categories (Get Started, Move Money, Investing, Spending, File Taxes, Your Profile) of the Wealthsimple Help Center. Useful as the entry point for taxonomy-driven exploration before drilling into sections and articles.

List sections, optionally filtered to one category. Sections group related articles (e.g. "TFSA", "Crypto deposits"). Pass a category_id from list_categories to scope.

Return article summaries (no body) inside a single section. Use after list_sections to discover specific articles, then call get_article for full content.

Fetch the full content of one article. By default returns a clean Markdown rendering of the article body (HTML stripped, links and headings preserved). Pass format: "html" for the raw HTML if needed.

Given a public help.wealthsimple.com article URL (e.g. https://help.wealthsimple.com/hc/en-ca/articles/4404053510299-Open-a-TFSA), fetch and return the full article. Useful for following citations or links the user has pasted.

Return a hierarchical map of the entire help center: every category → its sections → its article titles and IDs (no bodies). Use this to give an agent a holistic picture of what the help center covers, as a precursor to targeted retrieval. Result can be large (~hundreds of articles) — prefer search_help_center for narrow queries.
