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 | $0.00017 | $0.01591 |
| Opus 5 | $0.00009 | $0.00796 |
| Sonnet 5 | $0.00003 | $0.00318 |
| Haiku 4.5 | $0.00002 | $0.00159 |
Grade A, and why
notion scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -X GET "https://api.notion.com/v1/..." \ This is a copy
89% identical to notion — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 176 lines — stays where its author put it; the contents beside it link to each section on GitHub.
notion
Use the Notion API to create/read/update pages, data sources (databases), and blocks.
Setup
- Create an integration at https://notion.so/my-integrations
- Copy the API key (starts with
ntn_orsecret_) - Store it:
mkdir -p ~/.config/notion
echo "ntn_your_key_here" > ~/.config/notion/api_key
- Share target pages/databases with your integration (click "..." → "Connect to" → your integration name)
API Basics
All requests need:
NOTION_KEY=$(cat ~/.config/notion/api_key)
curl -X GET "https://api.notion.com/v1/..." \
-H "Authorization: Bearer $NOTION_KEY" \
-H "Notion-Version: 2025-09-03" \
-H "Content-Type: application/json"
Note: The
Notion-Versionheader is required. This skill uses2025-09-03(latest). In this version, databases are called "data sources" in the API.
Common Operations
Search for pages and data sources:
curl -X POST "https://api.notion.com/v1/search" \
-H "Authorization: Bearer $NOTION_KEY" \
-H "Notion-Version: 2025-09-03" \
-H "Content-Type: application/json" \
-d '{"query": "page title"}'
Get page:
curl "https://api.notion.com/v1/pages/{page_id}" \
-H "Authorization: Bearer $NOTION_KEY" \
-H "Notion-Version: 2025-09-03"
Get page content (blocks):
curl "https://api.notion.com/v1/blocks/{page_id}/children" \
-H "Authorization: Bearer $NOTION_KEY" \
-H "Notion-Version: 2025-09-03"
Create page in a data source:
curl -X POST "https://api.notion.com/v1/pages" \
-H "Authorization: Bearer $NOTION_KEY" \
-H "Notion-Version: 2025-09-03" \
-H "Content-Type: application/json" \
-d '{
"parent": {"database_id": "xxx"},
"properties": {
"Name": {"title": [{"text": {"content": "New Item"}}]},
"Status": {"select": {"name": "Todo"}}
}
}'
Query a data source (database):
curl -X POST "https://api.notion.com/v1/data_sources/{data_source_id}/query" \
-H "Authorization: Bearer $NOTION_KEY" \
-H "Notion-Version: 2025-09-03" \
-H "Content-Type: application/json" \
-d '{
"filter": {"property": "Status", "select": {"equals": "Active"}},
"sorts": [{"property": "Date", "direction": "descending"}]
}'
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.

notion is a skill published in the GitHub repository JansenAnalytics/claudex (5 stars, last pushed 2mo ago), licensed MIT. It adds 17 tokens to every session and 1,591 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 89% identical to notion, differing in 7 lines, and is treated as a copy.
