Answer questions about this codebase using the knowledge graph at .understand-anything/knowledge-graph.json.
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?}
file:path, function:path:name, config:path, article:pathedges[] — each has {source, target, type, direction, weight}
layers[] — each has {id, name, description, nodeIds[]}tour[] — each has {order, title, description, nodeIds[]}Check that .understand-anything/knowledge-graph.json exists in the current project root. If not, tell the user to run /understand first.
Read project metadata only — use Grep or Read with a line limit to extract just the "project" section from the top of the file for context (name, description, languages, frameworks).
Search for relevant nodes — use Grep to search the knowledge graph file for the user's query keywords: "$ARGUMENTS"
"name" fields: grep -i "query_keyword" in the graph file"summary" fields for semantic matches"tags" arrays for topic matchesid values of all matching nodesFind connected edges — for each matched node ID, Grep for that ID in the edges section to find:
Read layer context — Grep for "layers" to understand which architectural layers the matched nodes belong to.
Answer the query using only the relevant subgraph:
Analyze a codebase to produce an interactive knowledge graph for understanding architecture, components, and relationships
Use when you need to analyze git diffs or pull requests to understand what changed, affected components, and risks
Use when you need a deep-dive explanation of a specific file, function, or module in the codebase
Use when you need to generate an onboarding guide for new team members joining a project
Extract business domain knowledge from a codebase and generate an interactive domain flow graph. Works standalone (lightweight scan) or derives from an existing /understand knowledge graph.
Analyze a Karpathy-pattern LLM wiki knowledge base and generate an interactive knowledge graph with entity extraction, implicit relationships, and topic clustering.
