Kheish Compatibility

This skill is repo-local and stays inactive until explicitly activated.

When the original instructions refer to legacy tool names, use these Kheish mappings:

• `terminal` => `bash`
• `web_extract` => `web_fetch`, plus `web_search` when discovery is needed
• `search_files` => `grep_search` and `glob_search`
• `browser_*` tools require a browser-capable surfaced tool or MCP; if none is available, use the closest available surface and say so explicitly

When the instructions mention local helper files, resolve them from `${KHEISH_SKILL_DIR}`.

Notion API

Use the Notion API via curl to create, read, update pages, databases (data sources), and blocks. No extra tools needed — just curl and a Notion API key.

Prerequisites

1. Create an integration at https://notion.so/my-integrations 2. Copy the API key (starts with `ntn_` or `secret_`) 3. Store it in `~/.kheish/.env`:

   NOTION_API_KEY=ntn_your_key_here

4. **Important:** Share target pages/databases with your integration in Notion (click "..." → "Connect to" → your integration name)

API Basics

All requests use this pattern:

curl -s -X GET "https://api.notion.com/v1/..." \
  -H "Authorization: Bearer $NOTION_API_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json"

The `Notion-Version` header is required. This skill uses `2025-09-03` (latest). In this version, databases are called "data sources" in the API.

Common Operations

Search

curl -s -X POST "https://api.notion.com/v1/search" \
  -H "Authorization: Bearer $NOTION_API_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json" \
  -d '{"query": "page title"}'

Get Page

curl -s "https://api.notion.com/v1/pages/{page_id}" \
  -H "Authorization: Bearer $NOTION_API_KEY" \
  -H "Notion-Version: 2025-09-03"

Get Page Content (blocks)

curl -s "https://api.notion.com/v1/blocks/{page_id}/children" \
  -H "Authorization: Bearer $NOTION_API_KEY" \
  -H "Notion-Version: 2025-09-03"

Create Page in a Database

curl -s -X POST "https://api.notion.com/v1/pages" \
  -H "Authorization: Bearer $NOTION_API_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 Database

curl -s -X POST "https://api.notion.com/v1/data_sources/{data_source_id}/query" \
  -H "Authorization: Bearer $NOTION_API_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json" \
  -d '{
    "filter": {"property": "Status", "select": {"equals": "Active"}},
    "sorts": [{"property": "Date", "direction": "descending"}]
  }'

Create a Database

curl -s -X POST "https://api.notion.com/v1/data_sources" \
  -H "Authorization: Bearer $NOTION_API_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json" \
  -d '{
    "parent": {"page_id": "xxx"},
    "title": [{"text": {"content": "My Database"}}],
    "properties": {
      "Name": {"title": {}},
      "Status": {"select": {"options": [{"name": "Todo"}, {"name": "Done"}]}},
      "Date": {"date": {}}
    }
  }'

Update Page Properties

curl -s -X PATCH "https://api.notion.com/v1/pages/{page_id}" \
  -H "Authorization: Bearer $NOTION_API_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json" \
  -d '{"properties": {"Status": {"select": {"name": "Done"}}}}'

Add Content to a Page

curl -s -X PATCH "https://api.notion.com/v1/blocks/{page_id}/children" \
  -H "Authorization: Bearer $NOTION_API_KEY" \
  -H "Notion-Version: 2025-09-03" \
  -H "Content-Type: application/json" \
  -d '{
    "children": [
      {"object": "block", "type": "paragraph", "paragraph": {"rich_text": [{"text": {"content": "Hello from Kheish!"}}]}}
    ]
  }'

Property Types

Common property formats for database items:

• **Title:** `{"title": [{"text": {"content": "..."}}]}`
• **Rich text:** `{"rich_text": [{"text": {"content": "..."}}]}`
• **Select:** `{"select": {"name": "Option"}}`
• **Multi-select:** `{"multi_select": [{"name": "A"}, {"name": "B"}]}`
• **Date:** `{"date": {"start": "2026-01-15", "end": "2026-01-16"}}`
• **Checkbox:** `{"checkbox": true}`
• **Number:** `{"number": 42}`
• **URL:** `{"url": "https://..."}`
• **Email:** `{"email": "user@example.com"}`
• **Relation:** `{"relation": [{"id": "page_id"}]}`

Key Differences in API Version 2025-09-03

• **Databases → Data Sources:** Use `/data_sources/` endpoints for queries and retrieval
• **Two IDs:** Each database has both a `database_id` and a `data_source_id`
• Use `database_id` when creating pages (`parent: {"database_id": "..."}`)
• Use `data_source_id` when querying (`POST /v1/data_sources/{id}/query`)
• **Search results:** Databases return as `"object": "data_source"` with their `data_source_id`

Notes

• Page/database IDs are UUIDs (with or without dashes)
• Rate limit: ~3 requests/second average
• The API cannot set database view filters — that's UI-only
• Use `is_inline: true` when creating data sources to embed them in pages
• Add `-s` flag to curl to suppress progress bars (cleaner output for Kheish)
• Pipe output through `jq` for readable JSON: `... | jq '.results[0].properties'`
