## About PromptLayer with LuumenAI

Ask what changed in a prompt before you debug the output. Luumen connects to PromptLayer with an API key and reads your registry: PROMPTLAYER_GET_PROMPT_TEMPLATE for a specific version or release label, PROMPTLAYER_GET_REQUEST_LOG for one call's input, output, timing, and scores, PROMPTLAYER_LIST_TABLE_ROWS for eval data. Read-only, so nothing runs and nothing changes.

## Example tools

Read-only (16 in total):

- `PROMPTLAYER_GET_PROMPT_TEMPLATE` — Retrieve a prompt template version, release label, messages, model metadata, snippets, and optionally provider-ready kwargs without executing it.
- `PROMPTLAYER_GET_REGISTERED_TOOL` — Retrieve a PromptLayer registered tool definition by ID or name at a selected version or release label without test execution.
- `PROMPTLAYER_GET_REQUEST_LOG` — Retrieve one PromptLayer request log with its recorded input, output, timing, usage, metadata, tags, and scores.
- `PROMPTLAYER_GET_SKILL_COLLECTION` — Retrieve a PromptLayer skill collection and its files as JSON at a selected version or release label.
- `PROMPTLAYER_GET_TABLE` — Retrieve one PromptLayer Table's metadata and per-sheet row counts by UUID.
- `PROMPTLAYER_GET_WORKFLOW` — Retrieve a PromptLayer workflow definition by ID or name at a specific version or release label without running it.
- `PROMPTLAYER_LIST_FOLDER_ENTITIES` — Browse or search PromptLayer folders and registry entities in the API-key workspace, optionally recursively and with metadata.
- `PROMPTLAYER_LIST_PROMPT_TEMPLATES` — Search and page through PromptLayer prompt templates and snippets without executing a model.

## Frequently asked questions

### How does LuumenAI connect to PromptLayer?

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 PromptLayer on its own?

No. Every one of the 16 tools is read-only, so LuumenAI can answer questions from PromptLayer but cannot change anything in it.

### Is there an audit trail?

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