- run_cmd now returns Result<String, String> — callers pattern-match
instead of comparing against an "ok" sentinel string
- Add cmd_result() helper to format run_cmd results as tool strings
- mouse_click: collapse nested if-let into let-chain (clippy collapsible_if)
- nix fmt: reformat screen.nix package list
New crate hive-screen-mcp: a stdio MCP bridge activated automatically
when an agent has hyperhive.gui.enable = true. Provides five tools:
- screenshot — grim → saves PNG, returns path for Read tool
- type_text — wtype → Unicode text input (no daemon)
- key_press — ydotool key → combos like ctrl+c, super+l
- mouse_move — ydotool mousemove --absolute
- mouse_click — ydotool click, optionally with prior move
New nix/agent-modules/screen.nix: wires the MCP bridge into
extraMcpServers.screen; adds grim + wtype to systemPackages. Adds
hyperhive.gui.screenInput option (default false) which enables the
ydotoold daemon + ydotool for mouse/keyboard injection via /dev/uinput.
screenshot and type_text work without screenInput. key_press,
mouse_move, and mouse_click return a ydotool error until ydotoold is
running and /dev/uinput is accessible in the container.
