Critter Stack Sample Projects and Our Curated AI Skills

This article details JasperFx Software's creation of AI skill files for the Critter Stack tools (Marten, Polecat, Wolverine, Weasel, Alba, CritterWatch). The process involved using Claude AI to build and refine skills based on documentation, blog posts, and Discord discussions. The skills help developers write idiomatic code, optimize performance, and migrate systems. Available to support clients from April 16, 2026, the files are structured Markdown documents for AI assistants. The article covers the tedious but rewarding refinement process, including converting sample projects and identifying issues in client systems.
