AC ffbox

FFBox multimedia transcoding tool integration. FFmpeg-based GUI for video/audio/image format conversion, compression, filtering, batch media processing with visual control, remote transcoding, or API-based automation. WHY FFBOX OVER AI-GENERATED FFMPEG COMMANDS? (1) Visual task management: Dashboard to add/delete/pause/resume tasks with progress charts, while AI commands lack UI. (2) Learn FFmpeg: displays complete ffmpeg command prominently, showing full workflow (input→filter→encode→output). Users learn real FFmpeg skills. (3) Queue system: batch processing with pause/resume/retry. (4) Remote transcoding: offload work from low-power devices. (5) HTTP API for automation.

How to improve

  1. Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
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.

Against the Agent Skills spec

  • warning description-no-when description does not say WHEN to use the skill (no "use when")

Process rating: all ten parameters 51/100

  • 0Result and completion. Does not say what the result is
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 0Failures and branches. Linear process with no failure handling
  • 0Progress reporting. Says nothing while it works
  • 20When it triggers. No condition that starts the skill
  • 30Running it twice. 1 mutating operations with no state check
  • 100Tools and files. No external tools needed
  • 100Steps. 23 steps
  • 100Consistency. Name and required fields are in place
  • 100Execution cost. Instruction body is 1226 tokens

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.

Quality signals

  • +5Description has no quoted example phrases that should trigger the skill
  • +4Description does not say when NOT to use the skill (false activations)
  • +3Output format is not stated: the model decides each time
  • -2localhost URLs: will not work for another user
  • +1No license
  • +2Single-language instructions
  • +3Description length 680: enough signal without eating the budget
  • +4Structure: 26 headings
