About spec-miner

spec-miner
Reverse-engineering specialist
spec-miner is an agent skill from the jeffallan claude-skills collection that works as a reverse-engineering specialist, extracting specifications from existing codebases. It is meant for legacy or undocumented systems, inherited projects and codebases a new developer must learn. The skill uses two perspectives. The Arch perspective looks at system architecture and data flows, and the QA perspective looks at observable behaviour and edge cases. Its listed uses include understanding a legacy system with no documentation, writing documentation for existing code, onboarding onto a new codebase, planning enhancements to an existing feature, and extracting requirements from what the implementation actually does. The core workflow then guides the agent from reading the code to writing the specification it has recovered. The skill is useful because a written spec of current behaviour is often the missing starting point before a rewrite, a migration or a fix. Its output reflects what the code does, which may differ from what it was meant to do, so the skill is best used to start a conversation with the people who own the system. It is listed on skills.sh, where the page shows install counts and GitHub stars for the collection. Its Gen Agent Trust Hub audit is marked as failing, which the FAQ lists, while Socket and Snyk pass. Install it with npx skills add https://github.com/jeffallan/claude-skills --skill spec-miner.
