Context Optimizer (CCO) is a plugin bundle for AI coding tools published by Egor Fedorov. Marketplaces we read that list it: 1 (Community GitHub marketplaces). The last change we recorded was on 2026-10-18. As of our marketplace pass on 2026-10-20.
See what Claude costs you and spend less of it. In chat: hand a long chat over to a new one, digest long documents, set up Projects, check tokens, sharpen prompts. In Claude Code: a live line with context, cost, plan limits and the cache countdown; Haiku 5.5 subagents for reading and test runs; /cco audit of your own transcripts. Local, no telemetry.

Want this mark on your plugin in our catalog?
Prove you maintain it with a file in its repository, a file on your domain or a DNS record, and you can show this mark on the card, with live banners for your site and README. How verification works
You also get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.
Data comes from public marketplace files in GitHub repositories of their authors. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
