context-autopsy

Project intro

context-autopsy is a small tool that answers a question every heavy AI-coding-agent user has asked: what's actually filling your context window? It analyzes Claude Code and Codex sessions locally and shows how many tokens are being wasted. It ships as a CLI (bin/), a Claude Code plugin (.claude-plugin) and an agent skill (skills/context-autopsy), supports 13 coding agents, and is MIT licensed. The repo is actively maintained - commits from just days ago added support for 13 coding agents and polish on the share-card output. Author Alistair Clark posted it on Hacker News on October 14, 2026: "Very quickly vibe coded a tool to see how many tokens are being wasted!" A dogfooding loop worth noting: a tool for inspecting AI coding agents' context usage, built by vibe coding with those same agents.
