A set of procedures and tools for reading and updating Notion pages and databases from an agent or terminal. Notion is a workspace for documents, notes, and structured team information.

Use it to search pages and databases, retrieve content, answer questions from Notion, and update page properties after confirmation.

It helps an agent find the right information and makes shared edits explicit and reviewable before changing a workspace.

notion — Skill for Claude Code and Codex by magnus919

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add magnus919/agent-skills --skill notion

Clone the repo

git clone --depth 1 https://github.com/magnus919/agent-skills

Made for: Claude Code, Codex.

Its marketplace also offers this one on its own, as the plugin notion — /plugin install notion after adding the marketplace above.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00119	$0.01929
Opus 5	$0.00060	$0.00964
Sonnet 5	$0.00024	$0.00386
Haiku 4.5	$0.00012	$0.00193

Security

Grade A, and why

notion scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (tests/test_notion_cli.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Notion Operations

Use this skill to read and, with explicit confirmation, write Notion content through the Notion API: pages, database queries, search, and page property updates. This is a tool skill for the Notion platform. Building Notion integrations, writing complex block compositions, or building an app on the Notion API is application development; this skill owns the everyday agent workflow: finding the right page, answering from a database, and making a confirmed edit.

Operating contract

Read-only discovery before any mutation. Retrieve pages, query databases, and search freely. The bundled notion-cli script makes reads without writing anything.
Confirm the target, scope, and rollback path before acting. Creating a page or updating properties changes a shared workspace that teammates read. Both require an explicit human directive plus --dry-run preview and --yes confirmation through notion-cli. Property updates overwrite existing values — state the current value and the replacement before confirming.
Respect bounded reads. Notion paginates with page_size and has_more; never page past what the task needs. notion-cli --limit caps every search and query.
Keep evidence bounded. Quote short page titles, property values, and IDs; never paste full pages, tokens, or raw API payloads into chat.
Know the API version. The Notion-Version header pins the API contract; reads that work today can change with a version bump. notion-cli sends 2022-06-28 by default and honors NOTION_VERSION.

The notion-cli script

scripts/notion-cli is an agent-first, stdlib-only CLI over the Notion API. It covers the full issue scope: pages, databases (query), search, and updates.

notion/scripts/notion-cli --help                           # no token or network needed
notion/scripts/notion-cli --json pages get --page-id <page>
notion/scripts/notion-cli --json --limit 10 databases query --database-id <db>
notion/scripts/notion-cli --json search query --query "on-call runbook"
notion/scripts/notion-cli pages update --page-id <page> --properties props.json --dry-run
notion/scripts/notion-cli pages update --page-id <page> --properties props.json --yes
notion/scripts/notion-cli pages create --parent-database <db> --title "New row" --yes

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
