4d-doc-lookup - SKILL.md Agent Skill

name: 4d-doc-lookup description: Look up 4D documentation for commands, classes, or language concepts. Use when the user asks about a 4D command's syntax, parameters, or usage, needs class API reference, or wants to understand a 4D language concept. Resolves names to developer.4d.com URLs and optionally fetches page content.

4D Doc Lookup

Look up documentation from developer.4d.com for commands, classes, and topics.

Usage

# Get URL only (fast, no network needed)
python3 scripts/doc_lookup.py "JSON Parse"

# Fetch and extract page content
python3 scripts/doc_lookup.py "collection" --fetch

# Limit extracted text length
python3 scripts/doc_lookup.py "ORDA" --fetch --max-chars 2000

Query Types

The script auto-detects the query type:

Query	Resolves to	Example URL
Command name	`/commands/<slug>`	`ALERT` → `/commands/alert`
Class name	`/API/<ClassName>`	`collection` → `/API/CollectionClass`
`4D.File`, `cs.DataStore`	`/API/<ClassName>`	`4D.File` → `/API/FileClass`
Topic keyword	`/Concepts/<path>`	`orda` → `/ORDA/overview`

Output

  "url": "https://developer.4d.com/docs/commands/json-parse"
}

With --fetch, adds "content" field with extracted text.
