# grepai-embeddings-openai

A skill that wires OpenAI into GrepAI as the embedding provider, so indexing runs in the cloud with no local server. Your code goes to OpenAI.

## What it does

The skill walks through the `embedder` block in `.grepai/config.yaml`: provider, model, and an API key pulled from `OPENAI_API_KEY` instead of pasted into the file. The basic setup uses `text-embedding-3-small` at 1536 dimensions.

Two models are covered. `text-embedding-3-small` is the cheaper default pick, `text-embedding-3-large` gives 3072 dimensions and can be trimmed down to 1024 to save storage. For speed there is a `parallelism` setting, but the right number depends on your OpenAI tier — 1–2 on the free tier, 4–8 higher up. GrepAI batches chunks and backs off on its own when rate limits hit.

You need an OpenAI API key and billing enabled before any of this works. Switching from another provider means the old index is unusable: embeddings from different models can't be mixed, so `.grepai/index.gob` gets deleted and rebuilt. Since code leaves your machine, check what your ignore patterns actually exclude.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add yoanbernabeu/grepai-skills --skill grepai-embeddings-openai -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/grepai-embeddings-openai/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/grepai-embeddings-openai/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add yoanbernabeu/grepai-skills --skill grepai-embeddings-openai -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/grepai-embeddings-openai/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add yoanbernabeu/grepai-skills --skill grepai-embeddings-openai -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/grepai-embeddings-openai/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install yoanbernabeu/grepai-skills grepai-embeddings-openai
```

2. **Manually: put the files in place**
- File: `.github/skills/grepai-embeddings-openai/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add yoanbernabeu/grepai-skills --skill grepai-embeddings-openai -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/yoanbernabeu/grepai-skills --path skills/embeddings/grepai-embeddings-openai
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/grepai-embeddings-openai/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add yoanbernabeu/grepai-skills --skill grepai-embeddings-openai -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/yoanbernabeu/grepai-skills/tree/HEAD/skills/embeddings/grepai-embeddings-openai/SKILL.md

## When to use it
- set OpenAI as the embedding provider for GrepAI
- pick between text-embedding-3-small and text-embedding-3-large
- tune parallelism to match your OpenAI rate limit tier
- migrate an existing index from Ollama to OpenAI
- estimate indexing cost for a codebase

## Example prompts
- Configure OpenAI as the embedding provider for GrepAI in .grepai/config.yaml
- Use text-embedding-3-small with parallelism 8 for indexing
- Re-index the project after switching the provider to Anthropic

# GrepAI Embeddings with OpenAI

This skill covers using OpenAI's embedding API with GrepAI for high-quality, cloud-based embeddings.

## When to Use This Skill

- Need highest quality embeddings
- Team environment with shared infrastructure
- Don't want to manage local embedding server
- Willing to trade privacy for quality/convenience

## Considerations

| Aspect | Details |
|--------|---------|
| ✅ **Quality** | State-of-the-art embeddings |
| ✅ **Speed** | Fast, no local compute needed |
| ✅ **Scalability** | Handles any codebase size |
| ⚠️ **Privacy** | Code sent to OpenAI servers |
| ⚠️ **Cost** | Pay per token |
| ⚠️ **Internet** | Requires connection |

## Prerequisites

1. OpenAI API key
2. Billing enabled on OpenAI account

Get your API key at: https://platform.openai.com/api-keys

## Configuration

### Basic Configuration

```yaml
# .grepai/config.yaml
embedder:
  provider: openai
  model: text-embedding-3-small
  api_key: ${OPENAI_API_KEY}
```

Set the environment variable:

```bash
export OPENAI_API_KEY="sk-..."
```

### With Parallel Processing

```yaml
embedder:
  provider: openai
  model: text-embedding-3-small
  api_key: ${OPENAI_API_KEY}
  parallelism: 8  # Concurrent requests for speed
```

### Direct API Key (Not Recommended)

```yaml
embedder:
  provider: openai
  model: text-embedding-3-small
  api_key: sk-your-api-key-here  # Avoid committing secrets!
```

**Warning:** Never commit API keys to version control.

## Available Models

### text-embedding-3-small (Recommended)

| Property | Value |
|----------|-------|
| Dimensions | 1536 |
| Price | $0.00002 / 1K tokens |
| Quality | Very high |
| Speed | Fast |

**Best for:** Most use cases, good balance of cost/quality.

```yaml
embedder:
  provider: openai
  model: text-embedding-3-small
```

### text-embedding-3-large

| Property | Value |
|----------|-------|
| Dimensions | 3072 |
| Price | $0.00013 / 1K tokens |
| Quality | Highest |
| Speed | Fast |

**Best for:** Maximum accuracy, cost not a concern.

```yaml
embedder:
  provider: openai
  model: text-embedding-3-large
  dimensions: 3072
```

### Dimension Reduction

You can reduce dimensions to save storage:

```yaml
embedder:
  provider: openai
  model: text-embedding-3-large
  dimensions: 1024  # Reduced from 3072
```

## Model Comparison

| Model | Dimensions | Cost/1K tokens | Quality |
|-------|------------|----------------|---------|
