## Tools (3)

- `ask_henry`: Ask HenryKnows a question about F-1/J-1 student immigration, SEVIS, OPT, CPT or related rules and get a cited answer. Ask in the person's own terms; do not add identifiers. Answers take 10–40 seconds.
- `connect`: Connect to the HenryKnows page the person is watching (turns its light green) and get the session to pass on later calls. Call this first if the person gave you a session code; otherwise it is optional — ask_henry and search_sources connect too.
- `search_sources`: Search HenryKnows' knowledge base (regulations, SEVP/USCIS guidance, Federal Register rules) and get the matching passages with their source links, so you can read and cite the text yourself. Fast; no model call.
