message-agent

name	message-agent
argument-hint	<agent_name> <description of what to say>
description	Send a message to another mngr agent. Use when you need to communicate with a peer agent.
allowed-tools	Bash(echo "$MNGR_AGENT_NAME"), Bash(mngr message *), Bash(uv run mngr message *), Write(*), Skill(imbue-mngr-skills:find-agent)

The user's message contains a target agent name (the first word) and a description of what to communicate. Extract the agent name and treat everything after it as the intent/content of the message.

Your agent name is: !echo "$MNGR_AGENT_NAME"

Agent Name Resolution

Skip this step if the user seems to have provided the exact name of the agent -- just use the first word of their input directly as the target. Otherwise (for example they pasted a branch name like mngr/foo, or described the agent instead of naming it), run the /imbue-mngr-skills:find-agent skill, which explains how to find the exact agent name.

Composing the Message

Based on the user's description, compose the full message. Every message you send MUST:

1. Start with a sender tag: [from: !echo "$MNGR_AGENT_NAME"].
2. Contain the actual content: Write the message based on what the user described. Be clear and direct.
3. End with a reply instruction: Close with a line like: To reply, use the /imbue-mngr-skills:message-agent skill.

Example message (for an agent named refactor-auth):

[from: refactor-auth]

Hey -- I just finished refactoring the auth middleware on my branch. You'll want to rebase before merging since I changed the SessionStore interface. The new method is `get_session_by_token()` instead of `lookup()`.

To reply, use the /imbue-mngr-skills:message-agent skill.

Sending the Message

Write the composed message to a temporary file using the Write tool, then send it with --message-file. Name the temp file /tmp/mngr-message-from-YOUR_NAME-to-AGENT_NAME.txt (using your agent name and the resolved target name):

mngr message AGENT_NAME --message-file /tmp/mngr-message-from-YOUR_NAME-to-AGENT_NAME.txt

Use --message-file for all messages -- it avoids shell quoting issues and preserves formatting.

After Sending

Report to the user what you sent and to whom. If the send command fails, report the error.
