The team built a knowledge system powered by Claude skills, structured it to capture the existing codebase's behavior, and used the resulting documentation as a foundation for rewriting the project with modern technology. ## Content We keep hearing that AI can speed up our work, cutting development and improve delivery times... but how far can we actually push it? How much can AI really be part of both the BEFORE and the AFTER of development? In this article, I want to share a real experience: how we used AI to document an old legacy enterprise application. I'll walk you through the journey that led us to build a knowledge system powered by Claude, how we structured it, and where we ended up, all with one goal in mind: rewriting a legacy project with modern tech, starting from documentation that simply didn't exist. 🇮🇹 [https://www.thinkasadev.com/documentare-progetto-legacy-con-skill-claude/](https://www.thinkasadev.com/documentare-progetto-legacy-con-skill-claude/) 🇬🇧 [https://www.thinkasadev.com/en/documenting-legacy-project-claude-skills/](https://www.thinkasadev.com/en/documenting-legacy-project-claude-skills/) #claude #skill #enterprise #docs #legacy ## Similar posts on daily.dev - [Using Claude to Build an AI Knowledge Base in 30 Minutes](https://daily.dev/posts/using-claude-to-build-an-ai-knowledge-base-in-30-minutes-yt678a9qq) · Salesforce Engineering · 3 upvotes · 0 comments --- Tags: [#productivity](https://daily.dev/tags/productivity), [#claude](https://daily.dev/tags/claude), [#ai-assisted-development](https://daily.dev/tags/ai-assisted-development) [View this post on daily.dev](https://daily.dev/posts/real-case-study-documenting-a-legacy-project-with-claude-skills-ut5eh5etw) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"DiscussionForumPosting","mainEntityOfPage":"https://daily.dev/posts/real-case-study-documenting-a-legacy-project-with-claude-skills-ut5eh5etw","headline":"Real case study: documenting a legacy project with Claude skills","text":"A real-world case study of using Claude AI to document a legacy enterprise application that had no existing documentation.
