## Overview

This is a message-based text-generation service for a GenAI Discord bot. Its documented workflow is to obtain channel messages from a configurable keeper and generate text, with retries on failure; Redis-backed rate limiting is optional. The tree identifies entry-point, generator, helper, keeper, and middleware modules, but no source excerpts were provided, so code-level call ownership and detailed behavior cannot be verified. Dashed edges indicate documented capabilities or plausible connections whose implementation is unsampled.

Main entry points: [`src/genai_generator.nim`](https://github.com/genai-bot/generator-service/blob/master/src/genai_generator.nim) (Service entry), [`src/generator.nim`](https://github.com/genai-bot/generator-service/blob/master/src/generator.nim) (Text generator), [`src/keepers.nim`](https://github.com/genai-bot/generator-service/blob/master/src/keepers.nim) (Keeper access), [`src/middlewares.nim`](https://github.com/genai-bot/generator-service/blob/master/src/middlewares.nim) (Middleware)

## Components

### Service runtime

- [Service entry](https://github.com/genai-bot/generator-service/blob/master/src/genai_generator.nim): `src/genai_generator.nim`
- [Middleware](https://github.com/genai-bot/generator-service/blob/master/src/middlewares.nim): `src/middlewares.nim`
- **Redis**

### Text generation

- [Generator helpers](https://github.com/genai-bot/generator-service/blob/master/src/helpers.nim): `src/helpers.nim`
- [Text generator](https://github.com/genai-bot/generator-service/blob/master/src/generator.nim): `src/generator.nim`

### Message sources

- [Keeper access](https://github.com/genai-bot/generator-service/blob/master/src/keepers.nim): `src/keepers.nim`
- **Local messages**
- **Remote keeper**

### Other components

- **Service caller**

## Connections

- Service caller → Service entry: requests generation
- Service entry → Middleware: uses middleware
- Service entry → Text generator: invokes generation
- Text generator → Generator helpers: uses helpers
- Text generator → Keeper access: requests messages (evidence: `README.md`)
- Keeper access → Local messages: reads messages (evidence: `README.md`)
- Keeper access → Remote keeper: fetches messages (evidence: `README.md`)
- Middleware → Redis: rate limits with (evidence: `README.md`)
