The Agent Skills Directory

[SAFE]: The skill consists entirely of instructional markdown documentation without any executable scripts, binaries, or active configuration files.
[EXTERNAL_DOWNLOADS]: The skill references external documentation and research papers from well-known technology organizations and community projects, including Google's web.dev, Microsoft's developer blogs, and the HTTP Archive project. These references are for user information and do not involve automated code execution or software downloads.
[COMMAND_EXECUTION]: The skill frontmatter restricts the agent to a minimal set of tools (Read, Grep), effectively limiting the skill's capabilities to read-only operations on the filesystem.
[METADATA_POISONING]: All metadata fields, including description, scope, and examples, are consistent with the primary purpose of defining and enforcing web performance budgets.
