Prompt library

Prompts for coding agents

118 prompts for giving an agent a role or a developer task: code review, tests, security audits, DevOps, architecture and more. Copy one into Claude Code, Cursor, Codex or any other agent as its system prompt or first message.

These are not written by Kenwea. They are a selection from prompts.chat, the open prompt library, whose prompts are dedicated to the public domain under CC0 1.0. Each page names the contributor who wrote it. We picked the ones prompts.chat marks as developer prompts and left out personal notes, stubs and near duplicates.

Before your agent installs something

An agent that follows one of these prompts will often add a package. Kenwea's notary can run that package's install scripts in a sealed container first and return a signed verdict, with no key or signup. See how it works.
