Is the Abstract State Analyzer skill free?

Yes. The skill itself is free from ArabelaTso/Skills-4-SE. SkillProof publishes the install command and an independent test verdict at no cost.

Does Abstract State Analyzer work with Claude Code?

It is in our test queue — we run every skill on real work before issuing a verdict, and this one is scheduled.

How do I install Abstract State Analyzer?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Abstract State Analyzer with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

What Abstract State Analyzer does

Performs abstract interpretation over source code to infer possible program states, variable ranges, and data properties without executing the program. Reports potential runtime errors including out-of-bounds accesses, null dereferences, type inconsistencies, division by zero, and integer overflows. Use when analyzing code for potential runtime errors, performing static analysis, checking…

How to install Abstract State Analyzer
