Setting up Notion Research & Documentation in Codex

What the skill does

Notion Research & Documentation is a skill from OpenAI's official, curated skills catalog for Codex, published in the openai/skills repository. Per the provider's description, it is used to research across multiple Notion sources and synthesize the findings into structured documentation, such as quick briefs, comparisons, or comprehensive cited reports. The skill targets people who repeatedly need to gather information from existing Notion pages to produce consistent, traceable documents, instead of manually switching between pages and copying citations by hand every time.

Prerequisite: a Notion MCP connection

For the skill to work, the Codex client must be connected to Notion via the Model Context Protocol. Per the instructions, this is done with the command codex mcp add notion pointing at mcp.notion.com/mcp; in addition, the rmcp_client option under the features section must be enabled in config.toml, or Codex must be started with the --enable rmcp_client flag. A sign-in via OAuth through codex mcp login notion is then required. The skill detects a missing connection on its own: if a Notion call fails because the MCP server isn't set up, the assistant pauses the actual task and first walks through this setup process before continuing the research. Per the provider, a Codex restart is required after a successful login before the original research request can be resumed.

Workflow: gather sources, pick a format, synthesize

The actual workflow breaks into clearly separated phases. First, matching sources are found with the notion-search tool, refining queries as needed and confirming scope with the user when multiple results appear. Relevant pages are then fetched via notion-fetch, key sections are noted, and citations are captured for later reference. The skill then picks the appropriate output format using a bundled format-selection guide: a concise quick brief for fast overviews, a research summary for a deep dive into a single topic, a comparison for weighing options against each other, or a comprehensive, executive-ready report for deeper analysis. Before writing, an outline is drafted and findings are grouped by theme or guiding question, with gaps and contradictions in the sources explicitly flagged.

Creating and following up on the document

For the right document structure, the skill relies on bundled templates in its reference directory, for briefs, summaries, comparisons, or comprehensive reports. The finished page is created directly in Notion via notion-create-pages and includes a title, summary, key findings, supporting evidence, and, where useful, recommendations and next steps. Citations are added inline throughout the text as well as in a closing references section that links back to the original pages. As new information arrives, the document can be updated via notion-update-page, and the skill recommends tracking open questions, risks, and any follow-up tasks in a checklist.

Practical value and limits

The skill particularly suits teams that already maintain knowledge consistently in Notion and regularly need to condense it into decision briefs, competitive analyses, or technical investigations; matching example walkthroughs for competitor analysis, market research, and technical investigation ship with the skill. The quality of the results, however, depends directly on the quality and freshness of the underlying Notion content: the skill can only summarize and link what is actually present in the pages it searches, and it does not independently verify external facts outside Notion. Anyone wanting to incorporate information from other systems must first bring it into Notion or choose a different research path. Responsibility for factual accuracy and the final sign-off on a report also still rests with the person who commissioned the skill.
