The Agent Skills Directory

Configuration and State Management: The skill maintains a local cache file at ~/.config/fabric-collection/last-update-check.json. This is a standard practice for managing update frequencies (once per week) and does not involve sensitive user credentials.
Project Metadata Access: It accesses local package.json and plugin.json files to determine the current version and repository origin. This is a legitimate use of local project metadata to facilitate the update process.
Version Verification via GitHub: The skill uses official GitHub interfaces (Git CLI, MCP tools, or the GitHub REST API) to fetch version information. These requests are directed at trusted Microsoft-owned repositories, which is consistent with the skill's purpose.
Installation Guidance: It provides users with copy-pasteable commands for updating their local environment, such as git pull or executing local installation scripts (install.sh/install.ps1). These are manual update pathways that require user initiative and oversight.
External Content Display: The skill reads and displays CHANGELOG.md content. While this involves processing external text, the source is the official vendor repository, and the content is used for informative purposes regarding new updates.
