AI agents call get_playbook 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 retrieves or queries an existing playbook resource without modifying, deleting, or executing it. It is a simple lookup operation that returns data. The action is reversible and has no side effects on the system state. This fits the Read category definition: 'retrieves or queries data; no side effects (search, list, get, fetch).'
From the tool's definition Tool description: 'Retrieve a ClawSkills workflow playbook by name (slug).' The verb 'retrieve' and the read-only nature of fetching a playbook by identifier indicates data retrieval with no side effects.
