BF mac-monitor-brightness-control

Step-by-step guide for controlling external display or monitor settings on a Mac without third-party GUI apps. Covers Apple Silicon and Intel Macs, all major display brands (LG, Dell, BenQ, Samsung, ASUS, etc.), all connection types (USB-C, DisplayPort, HDMI, DVI), and a software fallback for displays that don't support DDC/CI. Controls include brightness, contrast, volume, input source switching, color temperature, power, and more. Use this skill whenever a user wants to control external display brightness, volume, contrast, color, input, or any other setting via the command line or keyboard shortcuts on macOS.

How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Will not run. References files that are not bundled: references/power-and-misc.md, references/*.md
  • 0Tools and files. 2 referenced file(s) missing: references/power-and-misc.md, references/*.md
  • 0Result and completion. Does not say what the result is
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 0Progress reporting. Says nothing while it works
  • 30Running it twice. 2 mutating operations with no state check
  • 40Consistency. Frontmatter name (mac-monitor-brightness-control) differs from the folder (mac-display-control)
  • 70When it triggers. States when to use, but not when not to
  • 100Steps. 11 steps
  • 100Failures and branches. 1 branches, has a failure section
  • 100Execution cost. Instruction body is 1412 tokens
  • low 10 top-level sections: this looks like several domains in one skill

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
