BuilderCheck — NSW builder licence & risk history

Search Australian (currently NSW) builders, contractors and building companies by name; optionally filter by postcode. Returns matching entities with their licence status and a slug to pass to get_builder_risk / get_builder_timeline. Example: query='Acme Building' → '- Acme Building Pty Ltd (Current), 2099 → slug: acme-building-pty-ltd-1a2b'. Names are matched loosely, so try the trading name AND the legal (Pty Ltd) name if the first search misses. Query must be at least 2 characters.

Get the factual risk profile for one builder by slug: NSW licence number/class/status (current, expired, suspended, cancelled), ACN/ABN and ASIC registration status (incl. deregistration/strike-off), disciplinary record count, and computed risk signals such as disciplinary history or licence problems. All facts come from official public registers, archived longitudinally by BuilderCheck. Use when a user asks 'is <builder> licensed?', 'is <builder> safe to sign a contract with?', or 'has <builder> been in trouble?'. Example: slug='acme-building-pty-ltd-1a2b' (get the slug from search_builders first).

Get the dated event timeline for a builder by slug: licence status changes, deregistration/strike-off, disciplinary findings, public warnings, and building work rectification orders. Each event carries its severity (info/watch/risk), the official register it came from, and a flag when the record was deleted upstream and now exists only in BuilderCheck's archive — cite that flag explicitly when present, it is the strongest signal. Returns up to 50 most recent events. Example: slug='acme-building-pty-ltd-1a2b' → '2026-03-14 — [risk] Building work rectification order (nsw.bc.rectification-orders)'.
