Understand Chat

This one helps you query codebases through a knowledge graph instead of grepping raw files. It assumes you've already generated a graph at `.understand-anything/knowledge-graph.json` with nodes for files, functions, classes, and edges showing imports, calls, and dependencies. The clever bit is it doesn't dump the entire graph into context. It uses grep to search for relevant nodes by name or tags, then pulls just the connected subgraph around your query. So if you ask about authentication, it finds those nodes and their immediate dependencies rather than loading everything. Works best when you need to understand how components relate without reading through dozens of files manually.

Answer questions about this codebase using the knowledge graph in the project's data directory (.ua/knowledge-graph.json, or the legacy .understand-anything/knowledge-graph.json when that directory is present).

Graph Structure Reference

The knowledge graph JSON has this structure:

project — {name, description, languages, frameworks, analyzedAt, gitCommitHash}
nodes[] — each has {id, type, name, filePath?, summary, tags[], complexity, languageNotes?}
- Code node types: file, function, class, module, concept
- Non-code node types: config, document, service, table, endpoint, pipeline, schema, resource
- Domain/knowledge node types: domain, flow, step, article, entity, topic, claim, source
- IDs use the node type as prefix, e.g. file:path, function:path:name, config:path, article:path
edges[] — each has {source, target, type, direction, weight}
- Key types: imports, contains, calls, depends_on, configures, documents, deploys, triggers, contains_flow, flow_step, related, cites
layers[] — each has {id, name, description, nodeIds[]}
tour[] — each has {order, title, description, nodeIds[]}
