Show Notes
Two tools to speed up understanding a new codebase: V Explain for architecture diagrams and call graphs, and Augment for Claude 4–powered AI help inside your editor. This demo uses an Astro site to show how the tools surface project structure and context quickly.
Tools in focus
-
V Explain
- What it does: automatically generates architecture diagrams, function graphs, and more from a codebase. It indexes the project to reveal the call graph, file tree, libraries, and data flow.
- How it feels to use: you can see a left-side chart with the architecture and, on the right, access to the index and other tooling. Right-click on a function name to view its call graph; right-click selected text to generate a diagram.
- Notable perks: shows a lot of project context in one view, including where data comes from (JSON) and how the site is composed (SEO, Tailwind, etc.). The demo notes it’s free.
- Limitations: certain languages/patterns (e.g., some Astro setups) may render call graphs less helpful; indexing speed depends on the codebase.
-
Augment
- What it is: an editor extension that ships with Claude 4, designed to give deeper AI-assisted insights as you explore and modify code.
- How it fits in: after indexing with V Explain, Augment surfaces FAQs, project information, and guided prompts to help you understand decisions and tradeoffs.
- Take on it: the presenter hasn’t fully explored Augment yet but highlights that it should offer “everything you’d expect from a cursor-based AI assistant and more.”
- Caveats: more to explore in a deeper setup; Claude 4 integration means you’ll want to be mindful of prompts and context length.
Astro example walkthrough
- What’s being examined: an Astro website with real-world structure
- Top-down flow: server renders the page layout; assets are served and wrapped into the page layer; meta and context are injected into components.
- Component map: the diagram surfaces the components and their file names, plus the libraries involved.
- Data sources: JSON files show how data is passed in (no backend in this example).
- SEO and styling: shows SEO setup and Tailwind usage.
- Practical takeaway: this kind of view helps you quickly understand where data, layout, and assets live without digging through files one by one.
Practical takeaways and actionable tips
- Use V Explain to build a living map of a codebase:
- Index the project to get a visual call graph and file tree.
- Right-click function names to inspect call graphs; right-click text to generate diagrams for difficult sections.
- Leverage the left diagram to understand how the site renders, where data and assets flow, and how components are wired together.
- Pair with Augment for deeper context:
- Let Augment surface project FAQs and summaries after indexing.
- Use Claude 4–powered prompts to reason about design decisions, bottlenecks, and potential refactors.
- Plan a deeper setup exploration for configurations, architecture decisions, and future-proofing.
- For onboarding teams:
- Introduce V Explain as a quick ramp tool to visualize architecture and data flow.
- Use Augment for onboarding notes, rationale behind choices, and consistent context across tasks.
- Be mindful of limitations:
- Some frameworks (like Astro) may not yield perfectly intuitive call graphs in every situation.
- AI assistants are powerful, but prompts and context length matter; verify critical insights with the codebase directly.
Next steps
- Expect a deeper dive focused on configuring Augment and getting the most out of Claude 4 within the editor.
- Try both tools on your current codebase to compare how much cognitive load you can save during ramp-up.
