Get the reviews on a pull request
AI agents call get_pull_request_reviews to retrieve information from Helm Chart CLI without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing pull request review data. It performs a read-only operation that does not create, modify, delete, or execute any actions. The verb 'get' combined with retrieval of reviews confirms this is a simple data retrieval function with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'get_pull_request_reviews' and description 'Get the reviews on a pull request' indicate data retrieval with no side effects.
