Fix and improve this skill with Tessl
tessl review fix ./skills/hig/SKILL.mdThe skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
The skill references an external Markdown mirror at sosumi.ai for fetching additional documentation, which constitutes an unverifiable runtime external dependency from an uncontrolled third-party publisher.
