Never Twice dont let the AI agent do mistake again

CogniCore released Never Twice, an open-source, local-first agent skill installed via `openclaw skills install @cognicore-dev/never-twice`, that records lessons from agent corrections and failures and checks them before acting. Lessons are stored in a local SQLite database at `~/.cognicore/mcp/lessons.db`, matched by words in a described action, and can be reviewed with `cognicore lesson list` or removed with `cognicore lesson forget <id>`. The skill is meant to be checked before tasks that change something — installing or removing packages, editing code or config, running tests, builds or migrations, committing, pushing or deploying — and skipped for questions, explanations and reading files.

Install openclaw skills install @cognicore-dev/never-twice Self-improving agent that never repeats a mistake. Learns from every correction and failure, remembers why, and checks only the relevant lessons before acting. Local-first, open source. You learn from mistakes and never repeat them. Lessons are stored by the cognicore command and checked before you act. Check lessons before any task that changes something: installing or removing packages, editing code or config, running tests or builds, running migrations, committing, pushing or deploying. Skip the check for questions, explanations and reading files. Run: Describe the kind of action in general words as well as the specifics, for example "install a package: add axios" or "format dates in the invoice export" . Lessons are matched by words. If it prints lessons, follow them, and tell the user in one short line which lesson you applied, for example: "Using pnpm lesson: npm breaks this repo's lockfile ." If it prints nothing, carry on; there is nothing to apply. If a lesson clearly doesn't apply to this task, ignore it and don't mention it. --why . One lesson per mistake, each field one sentence. --when names the situation broadly "installing or adding packages", "writing dates" , so the lesson is found next time even when the task is worded differently. --scope global only for lessons that apply in every project; the default is this project. Lessons are stored locally in the CogniCore data folder ~/.cognicore/mcp/lessons.db . Nothing leaves this machine. Users can review lessons with cognicore lesson list and delete one with cognicore lesson forget <id .
