description	Toggle LLMAnnotationTerminal — browser viewer for Claude Code output with structured annotations. Use /lat or /lat on to enable, /lat off to disable.

LLMAnnotationTerminal

Toggle the LAT browser sidecar for viewing and annotating Claude Code responses.

Usage

• /lat or /lat on — Enable LAT. Starts daemon if needed, opens browser.
• /lat off — Disable LAT. Daemon stays running but annotations stop injecting.
• /lat status — Show current state.

When active, responses are rendered in a browser with:

• Native markdown rendering (code highlighting, mermaid diagrams)
• Auto-detected questions and decision points (via Haiku)
• Annotation affordances (answer, choose, highlight, comment, approve, reject)
• Annotations inject as structured XML context on your next prompt

When Invoked

/lat or /lat on

Execute these commands:

mkdir -p ~/.lat
echo "on" > ~/.lat/active

Then check if the daemon is running:

curl -sf http://127.0.0.1:4747/health > /dev/null 2>&1

If the daemon is NOT running, start it (find the plugin root — it's the directory containing this SKILL.md's parent skills/ dir):

nohup bun run <PLUGIN_ROOT>/daemon/index.ts > /dev/null 2>&1 &
sleep 1

Then open the browser:

open http://127.0.0.1:4747

Confirm to the user: "LAT enabled. Browser opened at http://127.0.0.1:4747"

/lat off

mkdir -p ~/.lat
echo "off" > ~/.lat/active

Confirm: "LAT disabled. Annotations will not inject on next prompt. Daemon stays running."

/lat status

Check state:

STATE=$(cat ~/.lat/active 2>/dev/null || echo "off")
HEALTH=$(curl -sf http://127.0.0.1:4747/health 2>/dev/null && echo "running" || echo "not running")

Report: "LAT is $STATE. Daemon is $HEALTH."
