Explanations as visual pages in a pane beside the chat: diagrams drawn in place, the full page one click away. No model calls.

Asks before Claude edits a file another chat on this machine changed in the last 30 minutes. Each chat keeps its own small ledger; no model calls, no network.

Desktop heads-up display for the Pro plan: exact 5h/7d usage gauges, context gauge, turn receipts, usage in the spinner and compact tool cards. No estimates, no tokens spent.

Stops Claude reading a file over 1,000 lines whole and gives it an outline tool (definitions with line numbers) so it reads only the range it needs. A retry still reads it whole.

Stops Claude re-reading a file it already read in this conversation when the file has not changed since; a deliberate second attempt still goes through.

/receipt opens a pane with the exact tokens every turn of the session spent (uncached, cached, output, subagents) and the costliest turns. No tokens spent.

Moves tools you have not used lately behind ToolSearch, so their descriptions stop riding along on every request; core tools and anything you used in your last five sessions stay loaded.
