Composer

The composer is where you write messages in threads, pings, Sidekick, and teammate conversations.

What you can add

Use the composer to:

• Write a normal message.
• Mention a human teammate.
• Mention an AI teammate.
• Mention a connected app.
• Invoke a skill.
• Attach files.
• Decide whether the AI should respond.

Message formatting

Messages support Markdown formatting. Use $...$ for inline LaTeX math and $$...$$ for display math. Currency written as normal prose, such as $12K budget, renders as text. Escape ambiguous literal dollar signs as \$.

AI reply control

Some messages are requests for the AI teammate. Others are human discussion around the work. Use AI reply control so the thread can support both modes without forcing an agent response every time.

Good composer habits

Give the teammate the outcome, constraints, and relevant files or apps. If the task should follow a known workflow, invoke the relevant skill instead of restating the workflow manually.
