15Check the operational status of the Understand-Anything MCP server. Call this to verify if the knowledge graph is successfully loaded and active.
Check if a knowledge graph file is present and currently loaded. Returns instructions on how to generate the graph if missing.
Get a high-level statistical summary of the codebase knowledge graph. Returns total node and edge counts to gauge project size.
Generate a module-level architecture report from the knowledge graph. Returns a breakdown of files per directory to identify main components.
Generate a top-level dependency report from the knowledge graph. Identifies the most heavily depended-on files in the codebase (high fan-in).
Explain a specific part of the codebase by retrieving its 1-hop dependencies. Call this to understand what a file imports and where it is used.
Generate an onboarding overview document for new developers. Call this first when entering a new codebase to get oriented.
Find all callers of a specific function or file up to a certain depth. Helps trace execution paths.
Analyze the downstream impact of changing a specific file. Returns a list of files that depend on it.
Pre-flight architectural risk check. Call this before modifying any critical systems or refactoring to estimate risk radius.
Evaluate architectural constraints against the current knowledge graph. Generates a full violation report.
Mid-session continuous audit. Evaluate constraints to ensure recent changes haven't introduced violations.
Initialize a starter .ua-rules.json file in the workspace if one doesn't already exist.
Run a CI-style impact analysis on a PR diff to identify risk factors. Returns affected files, risk level, and potential issues.
Validate the structural integrity and syntax of the loaded knowledge graph JSON.
