The Agent Skills Directory

[COMMAND_EXECUTION]: The skill executes benign local commands such as git config, git remote, and basename to infer project metadata like the author name and repository name. These are standard operations for a development-oriented scaffolding tool.
[EXTERNAL_DOWNLOADS]: The skill provides instructions for the user to install standard, well-known software packages (mkdocs, mkdocs-material) from official registries to build the project. It does not perform any automated or hidden downloads itself.
[EXTERNAL_DOWNLOADS]: The templates reference external URLs for Creative Commons licenses and the author's own documentation. These are used appropriately for licensing and schema definitions.
[PROMPT_INJECTION]: The instructions include a confirmation step where resolved values are displayed to the user before any files are written, providing a manual check against unexpected behavior during text substitution.
