I didn't know what was in my context window. So I went looking.

After installing gstack, I wanted to dig deeper than vendor UIs into what actually lands in context. I built Context Mate as a local experiment to unify traces across Cursor, Claude Code, and Codex. So far it is only partly successful: useful for coarse Cursor buckets and Claude token curves, but not a full inventory by name, and fragile on undocumented storage.
