Use this skill when the user asks to run the migrated source command ccguide-refresh-docs.
Command Template
Use the refresh_official_docs MCP tool.
This fetches ~1.2MB from Anthropic (takes ~5s) and updates only the "current" snapshot. The baseline (set by init_official_docs) is never touched.
After success, show the quick diff preview against the baseline that the tool returns. Remind the user to run /ccguide:diff-docs for the full detailed diff.
