Norma consistently verifies AI-generated code against a set of governed rules, delivering the same outcome each time. This verification process occurs in two distinct environments: Livecheck, which assesses a specific file or code snippet upon request from editors such as Cursor, Claude Code, Windsurf, or VS Code, and Full Scan, which conducts a thorough audit of an entire GitHub or Bitbucket repository, identifying the technology stack and frameworks even in the absence of a configuration file, while prioritizing issues based on severity and providing the necessary context for remediation. Evaluations of the rules are conducted through static analysis, ensuring that results remain consistent across different runs. The rules are derived from SOLID design principles and specific conventions for various technology stacks, with the flexibility to disable those that are not applicable. The coverage of this system includes multiple programming languages and frameworks, such as JavaScript, TypeScript, Python, PHP, Java, Node, React, and Supabase. Additionally, the MCP server provides a range of functionalities, including link_repository, get_rulesets, get_rules_for_ruleset, live_check, get_open_issues, and register_applied_actions, all secured by OAuth and listed on the Official MCP Registry. This robust framework ensures that developers can maintain high code quality while adapting to various project requirements seamlessly.

Roomote functions as a cloud-based coding assistant designed to operate your true development environment, ensuring the accuracy of its outputs, conducting code reviews using distinct models, and delivering pull requests complete with real-time previews for user endorsement.
