The Agent Skills Directory

[NO_CODE]: The skill consists entirely of Markdown documentation, diagrams, and static PHP code snippets used for reference. There are no shell scripts, Python/Node.js executables, or automated tools included.
[SAFE]: All external references are to well-known, industry-standard PHP libraries and official PHP-FIG specifications. The skill provides configuration examples for composer.json which is standard practice for PHP project documentation.
[INDIRECT_PROMPT_INJECTION]: The file assets/psr-selection-guide.md includes template placeholders such as {PROJECT_NAME}. These are intended for the agent to use when generating a project-specific guide for a user. Since the skill has no tool access and does not process external untrusted data, this poses no security risk.
