Claude Code: deny. ### `workspace_note` - The description's first verb is "read": a word for reading. - The server marks it destructive (destructiveHint: true). - Tag private-data: The name "workspace_note" says "note": it reads notes. The description's first sentence says "read" and "note": it reads notes. Description, as the server wrote it: ```untrusted-server-text Read (text omitted) or replace (text given) one workspace note with a fixed name: about-us, connectors, events, team (shared by the workspace); voice, yb-preferences, send-log (per person). Up to 8,000 characters. Other names are refused. ``` ## Changes things (6) Creates or changes something that can be changed back. Claude Code: ask. ### `add_note` - The name "add_note" says "add": a word for a change. Description, as the server wrote it: ```untrusted-server-text A note on one firm, signed by the signed-in person and shared with the workspace, up to 2,000 characters. A "[YB] | | status= | …" line also sets that firm's status line on the user's lists.

Page 1 debits the workspace export pool once for the whole list; later pages of the same export the same day debit nothing. Up to 300 contacts per export (then contact columns are blank and contacts_truncated is true). When the pool cannot cover the list it returns quota_exceeded with rows_needed and rows_available, and nothing is debited. ``` ### `my_notes` - 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 Notes in this workspace that the user is allowed to read (their own, shared with them, or workspace-wide), optionally for one firm. Each note returns its id, author, date and text. Note text is written by workspace members. ``` ### `save_to_list` - The name "save_to_list" says "save": a word for a change. Description, as the server wrote it: ```untrusted-server-text Add firms to one of the user's workspace lists by name, creating the list when it does not exist (create_if_missing, default true). Safe to repeat: firms already on the list count as already_present and are not added again. At most 500 firm ids per call. Returns list_id, added, already_present. ``` ### `unlock_investor` - The name "unlock_investor" says "unlock": a word for a change. Description, as the server wrote it: ```untrusted-server-text Preview accounts only: opens one locked firm's full record (overview, AUM as stored, decision-maker names and positions, philanthropy, news, events) and counts it toward the account's 10 preview records; a firm already opened counts nothing. Returns the record and the number of preview records left; when none are left it returns no_unlocks_left. On full-access accounts it returns the same result as get_investor. Work emails and LinkedIn profiles are not part of preview records. ``` ### `yb_hello` - 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 Session opener for YedaBase (also YB or Yeda): the greeting line, where the person stands (tier, seat, lists, notes, due items), the one recommended next step and which playbook to read. Useful at the start of a conversation, when the user greets YedaBase, or asks where they left off. ``` ## Only reads (14) Looks things up and changes nothing.

Useful for side-by-side questions; one call covers what opening each firm would. ``` ### `count_investors` - The name "count_investors" says "count": a word for reading. Description, as the server wrote it: ```untrusted-server-text Counts matching firms and breaks them down by one to three dimensions, e.g. how many family offices in Texas by primary domain.
