notion

Notion CLI/API for pages, Markdown content, data sources, files, comments

notion is an agent skill from the OpenClaw project, listed on skills.sh. It lets an agent work with Notion pages, Markdown content, data sources, files, comments, search and Workers through the official ntn CLI, falling back to the Notion API with curl when needed. Like every skill, it is a SKILL.md file of instructions the agent reads when the task calls for it, so the agent knows which commands to run and what to avoid. It is free and open source in the openclaw/openclaw repository on GitHub.
