## About Customjs with LuumenAI

Use Customjs as both context and control. LuumenAI reads repos, pipelines, and runbook code to understand a change, then proposes pull requests, triggers jobs, or rolls back releases as approved, audited steps.

## Example tools

Read-only (5 in total):

- `CUSTOMJS_AUTHENTICATE_API_KEY` — Authenticate and validate a CustomJS API key.
- `CUSTOMJS_CONVERT_HTML_TO_PDF` — Convert HTML content to a PDF document.
- `CUSTOMJS_CONVERT_HTML_TO_PNG` — Convert HTML string to PNG image.
- `CUSTOMJS_MERGE_PDFS` — Merge multiple PDF files from URLs into a single PDF document.
- `CUSTOMJS_RUN_PUPPETEER_SCRIPT` — Execute a Puppeteer script in a headless browser and capture a screenshot.

## Frequently asked questions

### How does LuumenAI connect to Customjs?

Authorize once with API token. Luumen lists the scopes each action needs before you approve the connection, and credentials never appear in the chat.

### Can LuumenAI change things in Customjs on its own?

No. Every one of the 5 tools is read-only, so LuumenAI can answer questions from Customjs but cannot change anything in it.

### Is there an audit trail?

Every call to Customjs is recorded with the actor, the input, and the result.
