notion

notion is a skill for Claude Code from Panchangam18/background-computer-use. It costs 52 tokens per session (353 once invoked), scanned A, original, MIT.

A set of instructions for controlling the Notion desktop app through background computer use. Notion is a workspace where content is stored as separate blocks, such as paragraphs, headings, and database rows.

In plain words
What is it for?
Use it to edit Notion pages, add content blocks, create database rows, and manage pages through the app interface.
Why use it?
It handles Notion’s editor-specific behavior so actions such as typing, opening menus, and deleting pages are performed in the right way.

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.

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 6d ago.

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.

What it actually says

Driving Notion with background computer use

Notion is a block-based editor inside a WebView, so generic GUI heuristics fail in specific ways. Follow these rules in addition to the main computer-use skill:

  1. Always call get_app_state app="Notion" before interacting.
  2. Each paragraph/heading/bullet is a block. Return creates a sibling block of the same type; shift+Return is a soft line break.
  3. Type / at the start of a block to open the slash menu. The menu is async — re-call get_app_state before clicking a menu item.
  4. Do not use set_value on body text. Use click + press_key key="command+a"
    • type_text. set_value only works on native inputs (search, page title in some views), not on contenteditable blocks.
  5. Use perform_secondary_action with ShowMenu on sidebar rows instead of hovering to click the button.
  6. After any destructive action (delete page, archive), stop and confirm with the user before the next step.

Full behavioral notes live in server/app-hints/Notion.md — the MCP server injects them automatically inside <app_hints> on every get_app_state call for Notion.

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.
