AI agents call get_skill to retrieve information from Cawskills without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a straightforward query/retrieval of documentation or skill data by identifier. No side effects, write operations, code execution, or destructive actions are implied. The optional section parameter is a simple filtering mechanism. The low blast radius makes this a Read category risk with low severity.
From the tool's definition Tool name 'get_skill' and description 'Retrieve a ClawSkills skill doc by name' indicate a retrieval operation. The phrase 'Retrieve...by name' and optional section specification confirm read-only data access with no modification or deletion.
