Argument

$ARGUMENTS

Current state

!ls .uv-suite-state/lite-mode.txt 2>/dev/null && cat .uv-suite-state/lite-mode.txt 2>/dev/null || echo "off (no state file)"

What to do

1. Ensure .uv-suite-state/ exists (mkdir -p .uv-suite-state).
2. Parse $ARGUMENTS (lowercase, trim whitespace):
   • on — write on to .uv-suite-state/lite-mode.txt. Reply: Lite mode: ON.
   • off — write off to .uv-suite-state/lite-mode.txt. Reply: Lite mode: OFF.
   • status or empty — read the file (default off if missing) and reply with the current state.
   • Anything else — reply: Usage: /uvs-lite [on | off | status] and stop.
3. The change takes effect on the next user prompt (the lite-mode-inject.sh UserPromptSubmit hook reads the file each turn).

How lite mode works

When ON, a UserPromptSubmit hook injects terseness instructions into the assistant's context every turn:

• No preamble or end-of-turn summaries
• No bullet lists or markdown headers unless asked
• No code comments unless asked
• Inline file:line citations, not section headers
• Skip pleasantries

Also activates if the UVS_LITE=1 environment variable is set (useful for UVS_LITE=1 uv claude pro one-off sessions).
