CogniCore Releases Never Twice Lesson-Check Skill for AI Agents
Start here
CogniCore released Never Twice, a skill that lets an AI agent record lessons from its mistakes and check them before acting. Agents add a lesson with the `cognicore lesson add` command and run `cognicore lesson check` before any task that changes something, such as installing packages, editing code, running migrations or deploying. Lessons are matched by words and stored locally in `~/.cognicore/mcp/lessons.db`; CogniCore says nothing leaves the machine, and users can list or forget lessons. By default a lesson applies only to the current project; users add `--scope global` for lessons meant to apply in every project. CogniCore advises against storing passwords, tokens, keys or personal data in a lesson record, or keeping a lesson the user asked not to keep.
