Fix parsing issue with WebGPU testing skill

[adrastogi]

Description

The  webgpu-local-testing skill is failing to load because of invalid YAML in its frontmatter. The unquoated description: value contained colon-space sequences ( SCOPE: lavapipe ,  e.g.: ), and according to Copilot, in YAML a plain (unquoted) scalar can't contain ": ". The parser reads it as a nested mapping key and aborts with:

ScannerError: mapping values are not allowed here

It was the only one of the 8 skills with this pattern, which is why every other skill loaded fine. The fix is to wrap the description value in double quotes and adjust SCOPE:  to SCOPE - so the colons are treated as literal text. The frontmatter now parses, with both required keys (name, description) intact.

Motivation and Context

The Copilot CLI was flagging this skill as failing to load, so this change attempts to resolve that error.

Pull request overview

This PR fixes a YAML frontmatter parsing failure in the webgpu-local-testing agent skill by making the description field a quoted scalar so colon-space sequences are treated as literal text and the skill can load correctly.

Changes:

• Wrap the description frontmatter value in double quotes to prevent YAML scanner errors.
• Adjust the SCOPE: text within the description to avoid : sequences in the rendered string.

Should we add this into one of the SKILL.md or somewhere as a reminder?

Yeah, good question- I don't see a natural place to slot this, unfortunately. If this becomes a more systemic problem, perhaps we can re-evaluate if we need to add explicit instructions.
