eink-update

name	eink-update
description	Update the content of an active eink session on the Boox tablet. Use when iterating on a document mid-review without waiting for annotation events.

E-Ink Update

Push updated content to an existing active session. The tablet reloads automatically (~25 ms).

Usage

/eink-update [session-id]

Steps

1. Find the session

If a session-id was provided as an argument, use it.

Otherwise, list active sessions and let the user pick:

eink-review list --status active

If there is exactly one active session, use it. If there are multiple, ask the user which one to update.

2. Ask for updated content

Use the AskUserQuestion tool to ask: "What should the updated content be?"

Accept either:

• Raw markdown text pasted directly
• A file path (use it directly)
• "Current context" — synthesize a new markdown document from the conversation

3. Prepare the file

If the user provided raw markdown or asked for a synthesized document, write it to a temp file:

cat > /tmp/eink-update-XXXXX.md << 'EOF'
<content>
EOF

4. Push the update

eink-review update <session-id> /tmp/eink-update-XXXXX.md

On success, the server responds with the new version number. Tell the user the tablet has been updated.

On error:

• 404 → session not found
• 409 → session is not active (already submitted or cancelled)
• Connection refused → systemctl --user start eink-serve
