genvm_lint · Genlayer Cli MCP: Risk & Policy

WHAT IT DOES

What genvm_lint does on Genlayer Cli

AI agents invoke genvm_lint to trigger actions in Genlayer Cli. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why genvm_lint needs a policy

This tool executes an external linting process (genvm-lint) whose behavior depends on arguments passed to it. While linting is generally a read-only analysis activity, the capability to perform 'setup' and 'downloads' as mentioned in the description, combined with the Execute nature of running an external tool, places this in the Execute category.

From the tool's definition Tool 'genvm_lint' description states it can 'Run genvm-lint' which executes a linting command with parameters like 'validation, schema extraction, typechecking, setup, or downloads'. The verb 'Run' indicates code execution.
