Read a folder of receipt images/PDFs, append rows to a LibreOffice Calc bookkeeping ledger (description, category, type, amount), save, and start a Mail draft with the sheet attached.
Use when asked to QA Nimbus Desk, run a qa/*.md behavioral spec, verify UI behavior, check a regression, or confirm a UI fix. Drives the running app through the root Holo MCP tool, holo_desktop(task), and returns a QA report.
Sub-agent that binds to one OS window on the user's machine and drives it in the background via H Company's Holo3 VLM. If direct Holo tools are not visible, search for holo_desktop tools. In NemoClaw, call holo_desktop_launch once, then poll the same run_id until it finishes, passing attached images/files as media_paths.

Messages is a two-pane layout: conversation list on the left (newest at top), message thread on the right, composer at the bottom of the thread. iMessages render in blue bubbles, SMS/RCS in green — the color is the only persistent visual cue of which network is in use, which matters because SMS doesn't support read receipts, typing indicators, or rich reactions.
Cmd+N starts a new conversation; the To field autocompletes from Contacts and recent senders. Cmd+F searches inside the open conversation; Cmd+Opt+F searches across all conversations. Cmd+↑ / Cmd+↓ step through conversations in the sidebar. Cmd+1 through Cmd+9 jump to a pinned conversation. Cmd+Delete deletes the selected conversation (with confirmation).
In the composer: typing into the field starts a draft; Return sends, Opt+Return inserts a newline. This is the central gotcha — there is no Send button in the bare composer, the moment any text exists in the field a single Return keystroke makes it live.
Get the recipient right before typing anything. When the named person matches multiple contacts (common with first-name-only searches), the autocomplete picks the first match — verify the right one is selected by checking the To chip's expanded view before typing the body. SMS-only recipients (no Apple device) show a green-tinted chip and the composer says "Text Message" instead of "iMessage"; this is the user's signal that there are no read receipts and the message is going over the carrier.
Type the message in the composer, not in the answer. Match the tone of the thread if there's prior context: short replies in short threads, no greeting/sign-off mid-conversation, mirror emoji and language. A colleague who always responds in three words doesn't want a paragraph back.
Return sends immediately. Send is Irreversible. Apple's Undo Send (macOS Ventura+) gives a ~2-minute window via right-click → Undo Send on a just-sent message, but treat that as a safety net for typos, not as license to send before confirming. Stop after drafting, summarize recipient (and SMS-vs-iMessage if relevant) plus a one-line intent via answer, and wait for go-ahead. Don't repeat the body in the answer — the user can read it in the composer.
The composer also auto-sends on Return from any focus state inside it, including immediately after typing. If a draft is still being edited, leave the composer focused but don't press Return until confirmed.
Right-click (or two-finger click) on a message bubble opens the Tapback menu: heart, thumbs up, thumbs down, haha, !!, ?. Pick by clicking; the reaction posts immediately to everyone in the thread. Reactions are reversible (right-click and re-pick removes it) but the recipients have already seen the notification, so treat as semi-Irreversible.
In group chats, replies thread under a specific message via right-click → Reply. Without that, replies post to the whole group. Editing a sent message (right-click → Edit) is allowed for ~15 minutes; both the original and the edit show in the recipient's thread with an "Edited" badge.
