The Agent Skills Directory

[SAFE]: The skill uses the Agent and Skill tools for legitimate orchestration of development tasks.
[COMMAND_EXECUTION]: Employs the Agent tool to run parallel background tasks and creates temporary working directories in /tmp/skill-compare/. These operations are well-defined and aligned with the skill's stated purpose of building and comparing skill variations.
[INDIRECT_PROMPT_INJECTION]: The skill processes user-supplied specifications to generate new skill content. While this is an ingestion surface for external data, the synthesis and comparison steps provide a layer of agent review before the final skill is written to the persistent skill directory (~/.claude/skills/).
[EXTERNAL_DOWNLOADS]: The skill references other internal or platform-specific skills (skill-creator and superpowers) to assist in the generation process. It does not perform unauthorized network downloads or execute external scripts from untrusted sources.
