Two changes to make the skill packageable as an uploaded custom skill,
with no other content changes:
- Rename: the skill folder, the SKILL.md frontmatter name, and the
marketplace.json entry name and path. Skill names cannot contain the
reserved words "claude" or "anthropic" (per the agent skills
best-practices documentation).
- Description: shortened from 1,176 to 992 characters to fit the
1,024-character limit that skill upload validation applies to the
SKILL.md frontmatter description. The shortened text is the version
tested internally.
