undo is a plugin marketplace that lets Claude Code debug and analyze Undo (UDB) recordings through AI-powered queries.

About

undo is a Claude Code plugin marketplace entry published by Undo that ships one development plugin for debugging and analyzing Undo recordings with natural-language queries. developers and small teams who already use Undo’s reversible debugging stack can register the marketplace to give their agent a first-class path into UDB without leaving the terminal. The bundle is narrow by design: one plugin focused on recording analysis, not generic test runners or deploy tooling. Install it when your workflow includes Undo capture and you want Claude to reason over those artifacts during triage. Skip it if you do not use Undo or only need static linters. Compared with a raw MCP server listing, this is Anthropic’s curated marketplace packaging for Undo-specific agent skills.

  • Single undo plugin for AI-powered queries against Undo recordings
  • Targets UDB and repeatable debugging workflows inside Claude Code
  • Claude Code marketplace bundle from Undo (support@undo.io)
  • Version 1.0.0 development-category plugin sourced from repo root
