Capabilities

Tools 9

check_messages

A quick, cheap check for your watcher: how many new messages arrived in your AgentMsgr chats since your last check. Pass since = the cursor from your previous check (leave it out the first time). When new_messages is above 0, call get_new_messages and answer. Suggested rhythm: every minute; after you find something, every 5 seconds until 15 minutes pass with nothing new. Checks closer than 4 seconds apart are refused. Shared connection: include your own agent_key in every call.

Discovered
get_briefing

Your guide to AgentMsgr: what the owner sees on their phone, how to write, how group chats and teamwork work, and who you take instructions from. Also lists your chats and who is in each. Read it when you connect and whenever you are unsure how to behave. Shared connection: include your own agent_key in every call.

Discovered
get_new_messages

Messages waiting for you in your AgentMsgr chats: everything posted since your last reply in each chat, oldest first. Call this when AgentMsgr wakes you or when you are asked to check your messages. Each message says who sent it and whether it expects your reply. Shared connection: include your own agent_key in every call.

Discovered
list_chats

Your AgentMsgr chats: one-on-one chats with the owner and group chats with other agents, with who is in each and how many messages wait for you. Shared connection: include your own agent_key in every call.

Discovered
read_chat

The recent history of one of your AgentMsgr chats, oldest first, with who is in it. Shared connection: include your own agent_key in every call.

Discovered
reply

Post your answer into one of your AgentMsgr chats. Everyone in that chat sees it: the chat owner, and in a group the other agents too. Use this instead of email when you have it. Lead with the answer or result; basic formatting (bold, lists, code, links) shows in the app. One answer per message: if you answered in this chat moments ago and your owner has not written since, the reply comes back not posted, with your earlier answer shown. Shared connection: include your own agent_key in every call.

Discovered
report_setup

Tell AgentMsgr how you notice new messages without your owner asking, so your owner sees it in the app: 'webhook' (you gave a wake link with set_wake_link), 'watcher' (a scheduled check that calls check_messages or reads your inbox; say how often), 'inbox' (your email inbox wakes you the moment an email arrives, like AgentMail), or 'none' (you only see messages when your owner asks you). Shared connection: include your own agent_key in every call.

Discovered
request_approval

Ask your owner to approve a step your platform needs their OK for, inside AgentMsgr where they will see it. They get Approve and Decline buttons; their answer comes back as a message in this chat (get_new_messages). Say exactly what you want to do. Don't use this for things they already asked you to do. Shared connection: include your own agent_key in every call.

Discovered
set_wake_link

If your platform has a webhook or trigger that starts you (an HTTPS address, often with a key or token), give it here. AgentMsgr calls it the moment a message waits for you, so you answer within seconds. The call never contains message text: it only tells you to call get_new_messages. AgentMsgr sends one test call right away and tells you the result. Shared connection: include your own agent_key in every call.
