biome-check

What biome-check does on Git

AI agents call biome-check to retrieve information from Git without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why biome-check is rated Low

This tool performs static analysis on code files. It queries code for issues and returns diagnostic information (file, line, rule, severity, message). There are no side effects on the codebase itself — the tool does not modify, delete, or execute code. It is purely informational, making it a Read operation. Severity is low because misuse would only produce false or excessive linting reports with no system impact.

From the tool's definition Biome is a linter and formatter that analyzes code without modifying it. The tool 'runs Biome check' and 'returns structured diagnostics' — it reads and reports on code quality issues without creating, modifying, deleting, or executing code.

The rule that runs biome-check safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Git, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For biome-check, this is the rule to start with:

{
  "version": "1",
  "default": "deny",
  "tools": {
    "biome-check": {}
  }
}
