The file

We split this skill into the rules it gives an agent

1 rule. 0 are common, 0 are distinctive, and 1 is very specific to this project.

  • 0

    Common

    Most of the 23 edited versions we read keep these.

  • 0

    Distinctive

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Never use -y through the bridge unless overwriting was explicitly intended.

    line 18

“Common” is measured: kept by at least 6 in 10 of the 23 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

FFmpeg

Workflow

  1. Read ../../references/FFMPEG_TOOLKIT.md.
  2. Probe the actual source streams with FFprobe when stream structure matters.
  3. Query the local FFmpeg build for any optional codec, filter, protocol, device, or hardware feature before using it.
  4. Choose stream copy when no decode/re-encode is required; otherwise choose explicit codecs and filters appropriate to the delivery requirement.
  5. For complex work, construct a reproducible filter graph or portable tool manifest.
  6. Never use -y through the bridge unless overwriting was explicitly intended.
  7. Validate the output with FFprobe and the applicable media/delivery QC.

Raw bridge

python scripts/media_toolkit.py run ffmpeg -- ...
python scripts/media_toolkit.py run ffprobe -- ...

Done

The actual output exists, stream/container properties were checked when relevant, and the exact operation can be reproduced from saved arguments or a tool manifest.
