# Gamma

Turns a prompt into a Gamma deck, document or webpage and hands back a link or a PPTX/PDF file inside your host.

## What it does

Six tools ship with the server. `gamma_list_themes` and `gamma_list_folders` locate a theme or folder in the workspace, `gamma_generate` starts a presentation, document, webpage or social post, `gamma_create_from_template` clones an existing Gamma document and edits it, and `gamma_get_status` reports on generation and export progress. The API key goes in through `configure_gamma_api_key` or the `GAMMA_API_KEY` variable.

Generation runs asynchronously, so the host polls for status. `GAMMA_EXPORT_POLL_INTERVAL_MS` and `GAMMA_EXPORT_POLL_MAX_ATTEMPTS` control how often and how many times, while `GAMMA_REQUEST_TIMEOUT_MS` caps the outbound HTTP call to both Gamma and the host bridge. Seeing `TIMEOUT` on slow submits means that cap is too low for your network.

Node.js 20+ and npm are required. Text coming back from Gamma — theme and folder names, keyword arrays, error strings, URLs — arrives wrapped in `<untrusted-content>` so the model reads it as data instead of instructions. Nothing works until a valid Gamma API key is in place.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `GAMMA_API_KEY`, `GAMMA_EXPORT_POLL_INTERVAL_MS`, `GAMMA_EXPORT_POLL_MAX_ATTEMPTS`, `GAMMA_REQUEST_TIMEOUT_MS` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- turn a written brief into a finished Gamma deck
- export a deck as PPTX or PDF
- look up the ID of a custom corporate theme
- clone an existing Gamma document and rewrite it
- wait out an async export and collect the file

## Example prompts
- List the Gamma themes and find our custom one
- Clone the document in that folder and rewrite it for the new report
