Customizing Statusline

Use this skill to create or update the global Letta Code statusline mod:

~/.letta/mods/statusline.tsx

The statusline is a panel registered at order: 0 — the primary line just below the input. It overrides the built-in agent · model line. Host UI can still temporarily preempt it for safety confirmations and transient hints.
