An optional note of up to 200 characters (school, year, what role they are after) can be included; confirm the person and the note with the user before calling.

Offer it once after a new member's first request goes out (a text when someone accepts), or when a member asks for texts; if they decline, do not ask again.

Follow with verify_phone. ``` ### `connect_account` - The description's first verb is "link": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Permanently link the user's Nepternship account to this assistant so they do not need to sign in again in future conversations. Call this when the user asks to connect, stay signed in, or after they finish signing up and want to keep using Nepternship here. ``` ### `finish_signup` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Complete a sign-up started with sign_up once the user has clicked the confirmation email. Returns the connector token for the new account, the held intro request if one exists, and three suggested first introductions.

Description, as the server wrote it: ```untrusted-server-text Email a 6-digit sign-in code to an existing Nepternship member. Use this when a member who is not connected in this conversation wants to use their account (see their introductions, send a request). Returns a claim_code; after verify_code succeeds, pass that claim_code on every later call. ``` ### `sign_up` - The description's first verb is "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

With no arguments it returns the overview; pass one of company_id, role_id or industry_id from a previous result to open that group.

Searches the Nepternship network of students and recent graduates across 3,000+ companies, including Goldman Sachs, JPMorgan, Google, Meta, McKinsey and Deloitte. Returns members grouped by company, role and industry, each with first name and last initial, who they can introduce the user to, and an opportunity_id for send_intro_request.
