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.

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 | $0.00126 | $0.01770 |
| Opus 5.5 | $0.00050 | $0.00708 |
| Sonnet 5.5 | $0.00025 | $0.00354 |
| Haiku 4.5 | $0.00013 | $0.00177 |
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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Notion CLI Skill
Operate Notion workspaces using ncli. Two backends:
- MCP (OAuth) — search, pages, databases, views, comments, users, teams
- REST API (integration token) — file upload, block operations, any REST endpoint
Prerequisites
# MCP auth (required for most commands)
ncli whoami # Check auth status
ncli login # If not authenticated
# REST API auth (required for ncli rest / ncli file commands)
ncli rest login # Save integration token (one-time)
REST API requires integration access to target pages: Go to https://www.notion.so/profile/integrations/internal → select your integration → Content access → add pages.
Core Pattern: Search → Fetch → Act
- Search —
ncli search "<query>" --jsonto find pages/databases - Fetch —
ncli fetch <id> --jsonto get details and extract IDs - Act — Use the extracted IDs to create/update/query
See references/id-patterns.md for ID extraction patterns.

What ships with it
2 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.
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.
- 2mo ago First seen · 174 lines · 126 tokens per session scan A b1d68b7160cd
notion is a skill published in the GitHub repository nyosegawa/notion-cli (57 stars, last pushed 7mo ago), licensed MIT. It adds 126 tokens to every session and 1,770 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
