description	Control the local machine — volume up/down/mute/set, screen brightness, lock screen, suspend. Pure execution, no communication. Mock backend (binding-only) for the thesis benchmark.

System Skill

Use this skill for local-machine control: adjusting audio volume, setting screen brightness, locking the screen, and suspending the machine. It is a canonical reflexer case — every request maps to a single side-effecting shell command with no dialogue and no information return beyond a status line. Deterministic intent → one command → execute.

Mock / binding-only. In this thesis benchmark the sys CLI is a mock that echoes a JSON status line WITHOUT touching real hardware — we evaluate command correctness (does the reflexer emit the right subcommand/level?), not real device effects. To target a live machine, wire the subcommands to pactl/wpctl, brightnessctl, loginctl, etc.

Commands (via bash)

CLI: python3 agents/skills/system/sys.py <command> [args] (aliased sys).

Volume up / down / mute (the direction subcommand is the discriminator)

sys volume up sys volume down sys volume mute

Set volume to an explicit level (hard sibling: same volume, the --level slot discriminates)

sys volume set --level <0-100>

Set screen brightness

sys brightness set --level <0-100>

Lock the screen / suspend the machine

sys lock sys suspend

Flags

• --level <0-100> target level (volume set, brightness set)

Output format

One JSON line: {"ok": bool, "data": {...}, "error": null|{...}, "meta": {"mock": true}}. Exit 0 on success, 2 on bad args.

Sibling families (why this skill is in the benchmark)

volume up / volume down / volume mute share the volume subcommand and differ only in the direction word — a dense action-sibling family. volume set is a hard sibling of those (same volume subcommand, distinguished only by the --level slot, mirroring the HA brightness case). lock / suspend form a second power/session sibling pair. These dense siblings stress the router's action-discrimination — the dominant failure mode (sibling collision).
