Contexter — for developers

Finding out what is already there. Nothing changes.

list_contexts: Every context you can open — your own and the ones shared with you — each with the people who see it.
get_context_card: One context at a glance: what it is about, how much is in it, who is in it, what arrived last. Built by the server, not retold by the model.
get_context_feed: The records of one context, page by page, with markers where something was deleted.
list_records: Everything you have — Telegram messages and saved AI results — searchable.
list_sources: Which chats your records came from, under their human names.
get_artifact: The full text of one saved result, not just its opening lines.
get_file: A download link for a file attached to a record. Single use, fifteen minutes.
read_image_content: The picture itself, handed to the model that asked for it — not a link to it.

Putting something in, and correcting it afterwards.

save_artifact: Save a result of the conversation into a context. A context of the same name is reused, never duplicated.
save_file: Save something the assistant composed as a file — a table, a document, an image.
create_context: Start an empty context. Empty is a valid state.
add_records_to_context: File records you already have into a context. Messages and results mix freely.
update_artifact: Edit a saved result of your own. Telegram messages are never editable.
update_context: Rename your context or change its description.
set_context_notifications: Turn the alerts about a shared context on or off. Yours alone: it changes nothing for anybody else in it.

Letting a person in, and taking them out again.

share_context: Two steps. First you see how many records, and whose, a new member would immediately read; only after you agree is an invitation issued. It arrives as a card in your own Telegram, where you pick the recipient with Telegram's chat picker — no link is ever printed into the chat.
revoke_context_access: Take a person out of a context. Owner only, always by hand.
check_share_audience: Who would see a context if you shared it, asked before anything is shared. The confirmation that follows names those people.
deliver_to_chat: Publish a result into a Telegram group you take part in — your assistant’s words, and existing records alongside them. It never sends by itself: a confirmation card appears in your private chat with the bot, showing the chat, the text and how many people will read it, and the message leaves only when you press it. What arrives joins that chat’s records under your name, with buttons to file it into one of the chat’s contexts.
invite_room_to_context: Invite the people of a Telegram group into a context made from that group. Only those who have opened the bot to the room can accept.

Taking things out — and putting them back, which is half of this group.

remove_record_from_context: Unfile a record from one context. It stays with its owner.
delete_record: Delete your own record everywhere. Soft for 7 days.
leave_context: Step out of a context shared with you. It needs nobody's permission, because it takes access away rather than granting it. What you added stays.
restore_record: Undo that, inside the seven days.
delete_context: Delete the context, not its contents. Records stay with their owners.
restore_context: Bring the context back, with its records and its members.
