Frequently asked questions
AI-generated answers based on this skill's SKILL.md and metadata
What does understand-diff do with git diff changes?
understand-diff analyzes your git diff against your project's knowledge graph to identify which components were modified and trace their dependencies. It maps code changes across architectural layers, surfaces affected downstream components, and highlights potential risks so you can understand the full blast radius of your modifications before merging.
How does understand-diff assess risk and impact on my codebase?
understand-diff compares code changes to the project knowledge graph and traces dependency chains to reveal what else might be impacted. It evaluates which architectural layers are touched, identifies cross-layer concerns, and generates a risk assessment overlay showing potential downstream effects of your pull request changes.
Can understand-diff show me which components are affected by changes?
Yes. understand-diff identifies affected components from your code diff by mapping modifications against the knowledge graph, then traces dependency chains to surface both direct and indirect impacts. It highlights which architectural layers are touched and displays results in a visual diff overlay for dashboard exploration.
What's the difference between understand-diff and a standard git tool?
understand-diff goes beyond file-level diffs by understanding your codebase structure through a knowledge graph. It traces dependencies, maps architectural layers, and reveals downstream impact—not just what files changed, but what components and systems are affected and why, enabling informed risk assessment before merging.
How can I use understand-diff to understand code changes and dependencies?
understand-diff compares your pull request changes to the project knowledge graph, surfacing modified components and their dependency chains. It traces cross-layer concerns and generates a visual diff overlay in the dashboard, letting you explore which dependencies are impacted and understand the full scope of your modifications.
SKILL.md
Rendered from the published skill. Quoted content, verbatim.
/understand-diff
Analyze the current code changes against 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,

Query your codebase with natural language by leveraging a knowledge graph that maps files, functions, classes, and their relationships. understand-chat searches the graph to find relevant code nodes and connections, then explains how components link together across your project's architecture.
understand-onboard builds structured onboarding documentation by reading your project's knowledge graph to surface architecture layers, key files, design patterns, and complexity hotspots. It produces a guided walkthrough tailored to help new developers navigate the codebase efficiently. The generated guide can be saved to your repo for team reference.
understand-explain delivers thorough, in-depth analysis of any code component by traversing your project's knowledge graph to surface its role, internal structure, dependencies, and data flow. It resolves the target node, traces connected edges, and reads source code to explain the component within its architectural layer and broader codebase context.
understand-domain pulls business domain knowledge—domains, workflows, and process steps—from your codebase and renders an interactive flow graph. It works efficiently by deriving from an existing knowledge graph when available, or runs a lightweight scan to build one from scratch.
Understand scans your codebase and builds an interactive knowledge graph stored as JSON, letting you explore your project's architecture and component relationships through a visual dashboard. Configure analysis scope with language preferences, exclusion patterns, and auto-update settings.
This skill connects to your Figma file via the REST API to map its structure—pages, screens, components, instances, and design tokens—into an interactive knowledge graph. The result appears as a searchable, explorable dashboard within your existing environment.
