COG is an AI-assisted second brain that stores knowledge in Markdown files and uses agents, skills, and version control to evolve it over time. It helps people manage knowledge and contacts while supporting several coding-agent tools; the catalogue entries are COG’s skills, agents, instructions, rules, and plugin surfaces.
Latest release v3.10.0 — v3.10.0: Agent Plugins Standard · 7 Aug 2026
These files are huytieu/COG-second-brain's own configuration. They tell Cursor, Codex, OpenCode, Claude Code and Gemini CLI how to work on this repository, so they are not mods to install elsewhere. Copy one as a starting point and replace the parts that are about this project.
