## What it does

The skill guides an agent through common GrepAI failures and the checks used to isolate them. It covers version and project status, `.grepai/config.yaml`, index contents, the watch daemon, and Ollama connectivity through `curl http://localhost:11434/api/tags`.

Its procedures show how to initialize and rebuild an index with `grepai init` and `grepai watch`, restart file watching, inspect ignored files, and tune search or storage settings. Other sections cover symbol tracing, MCP setup, memory pressure, slow searches, and invalid `OPENAI_API_KEY` values.

GrepAI search requires an index, so `grepai init` must come before `grepai watch`. When Ollama is the embedding provider, start it with `ollama serve` and download `nomic-embed-text` using `ollama pull nomic-embed-text`.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add yoanbernabeu/grepai-skills --skill grepai-troubleshooting -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/advanced/grepai-troubleshooting/SKILL.md

## When to use it
- diagnose empty GrepAI search results
- recover from a missing project index
- test Ollama and embedding-model connectivity
- refresh an outdated watch index
- inspect MCP and OpenAI API-key failures

## Example prompts
- Find out why GrepAI returns no matches and run the checks around `grepai status`.
- Diagnose the Ollama connection and test `http://localhost:11434/api/tags`.
- Investigate why `grepai trace callers` cannot locate symbols in this project.

# GrepAI Troubleshooting

This skill provides solutions for common GrepAI issues and diagnostic procedures.

## When to Use This Skill

- GrepAI not working as expected
- Search returning poor results
- Index not updating
- Connection or configuration errors

## Quick Diagnostics

Run these commands to understand your setup:

```bash
# Check GrepAI version
grepai version

# Check project status
grepai status

# Check Ollama (if using)
curl http://localhost:11434/api/tags

# Check config
cat .grepai/config.yaml
```

## Common Issues

---

### Issue: "Index not found"

**Symptom:**
```
Error: Index not found. Run 'grepai watch' first.
```

**Cause:** No index has been created for this project.

**Solution:**
```bash
# Initialize if needed
grepai init

# Create the index
grepai watch
```

---

### Issue: "Cannot connect to embedding provider"

**Symptom:**
```
Error: Cannot connect to Ollama at http://localhost:11434
```

**Causes:**
1. Ollama not running
2. Wrong endpoint configured
3. Firewall blocking connection

**Solutions:**

1. Start Ollama:
```bash
ollama serve
```

2. Check endpoint in config:
```yaml
embedder:
  endpoint: http://localhost:11434  # Verify this
```

3. Test connection:
```bash
curl http://localhost:11434/api/tags
```

---

### Issue: "Model not found"

**Symptom:**
```
Error: Model 'nomic-embed-text' not found
```

**Cause:** The embedding model hasn't been downloaded.

**Solution:**
```bash
# Download the model
ollama pull nomic-embed-text

# Verify
ollama list
```

---

### Issue: Search returns no results

**Symptom:** Searches return empty or very few results.

**Causes:**
1. Index is empty
2. Files are being ignored
3. Query too specific

**Solutions:**

1. Check index status:
```bash
grepai status
# Should show files > 0 and chunks > 0
```

2. Verify files are being indexed:
```bash
# Check ignore patterns in config
cat .grepai/config.yaml | grep -A 20 "ignore:"
```

3. Try broader query:
```bash
grepai search "function"  # Very broad test
```

---

### Issue: Search returns irrelevant results

**Symptom:** Results don't match what you're looking for.

**Causes:**
1. Query too vague
2. Boosting not configured
3. Wrong content indexed

**Solutions:**

1. Improve query (see `grepai-search-tips` skill):
```bash
# Bad
grepai search "auth"

# Good
grepai search "user authentication middleware"
```

2. Configure boosting to penalize tests:
```yaml
search:
  boost:
    enabled: true
    penalties:
      - pattern: /tests/
        factor: 0.5
```

3. Check what's indexed:
```bash
grepai status
```

---

### Issue: Index is outdated

**Symptom:** Recent file changes aren't appearing in search results.

**Causes:**
