Shikhu – Understand the code your agents write

Hacker News

Agents write code really well, but it can get hard to understand what they've written and why. Shikhu is a CLI tool and Agent Skill that facilitates learning your code through self-quizzing, transcript analysis, and validation flows. I'm Arjun, I'm currently a developer advocate at Pinecone, and I use agents to code a lot! I enjoy using agents to code, but I've been feeling like I've lost some conceptual learning and understanding that comes with writing the code yourself. I wanted to make a tool that would make it easy to re-build habits around learning, while complementing workflows that use agents. I found inspiration for the tool from reading a research paper on skill formation from Anthropic, and Shikhu is the result of my attempt to build a tool around that: https://arxiv.org/abs/2601.20245 Shikhu focuses on helping develop conceptual understanding via knowledge coverage on a file-level. Shikhu makes multiple choice quizzes on a file-level for you to take. You can reject a malformed question, answer it, and eventually create validated "golden" question sets for your code. Your ability (or, anyone who you collaborate with) to answer golden questions about your code corresponds to your knowledge coverage. Using the skill, you can learn specific files with your own coding agents, and use those conversations to inform quiz development, to help reinforce learnings. Repo is here, it's free to use, and requires an Inception API Key for question generation and summarization: https://github.com/arjunpatel7/shikhu Install Shikhu with uv: uv tool install shikhu Install the agent skill afterwards: shikhu init shikhu install-skill As of writing, the free tier of Inception's pricing should cover typical use. My article where I explain more about Shikhu is here: https://www.arjunkirtipatel.com/blog/introducing-shikhu It's definitely rough around the edges, probably will change a lot and maybe has a few bugs, but I found it useful enough to share. Thanks for reading! -Arjun
