# Prompt Library System

**Multi-model prompt variants with integrated evaluation framework for testing and validation.**

---

## 🎯 Quick Start

### Testing a Prompt Variant

```bash
# Test with eval framework (recommended)
cd evals/framework
npm run eval:sdk -- --agent=openagent --prompt-variant=llama --suite=smoke-test

# Test with specific model
npm run eval:sdk -- --agent=openagent --prompt-variant=llama --model=ollama/llama3.2 --suite=core-tests

# View results
open ../results/index.html
```

### Using a Variant Permanently

```bash
# Switch to a variant
./scripts/prompts/use-prompt.sh --agent=openagent --variant=llama

# Restore default (canonical agent file)
./scripts/prompts/use-prompt.sh --agent=openagent --variant=default
```

**Architecture:**
- **Agent files** (`.opencode/agent/*.md`) = Canonical defaults (source of truth)
- **Prompt variants** (`.opencode/prompts/<agent>/<model>.md`) = Model-specific optimizations
- **Results** always saved to `.opencode/prompts/<agent>/results/` (including default)

---

## 🧪 Evaluation Framework Integration

### Running Tests with Variants

The eval framework automatically:
- ✅ Switches to the specified variant
- ✅ Runs your test suite
- ✅ Tracks results per variant
- ✅ Restores the default prompt after tests

```bash
# Smoke test (1 test, ~30s)
npm run eval:sdk -- --agent=openagent --prompt-variant=llama --suite=smoke-test

# Core suite (7 tests, ~5-8min)
npm run eval:sdk -- --agent=openagent --prompt-variant=llama --suite=core-tests

# Custom test pattern
npm run eval:sdk -- --agent=openagent --prompt-variant=llama --pattern="01-critical-rules/**/*.yaml"
```

### Auto-Model Detection

Variants specify recommended models in their YAML frontmatter:

```yaml
---
model_family: llama
recommended_models:
  - ollama/llama3.2
  - ollama/qwen2.5
---
```

If you don't specify `--model`, the framework uses the first recommended model.

### Results Tracking

Results are saved in two locations:
1. **Main results:** `evals/results/latest.json` (includes `prompt_variant` field)
2. **Per-variant:** `.opencode/prompts/{agent}/results/{variant}-results.json`

View in dashboard: `evals/results/index.html` (filter by variant)

---

## 📝 Creating a New Variant

### Step 1: Copy Template

```bash
cp .opencode/prompts/openagent/TEMPLATE.md .opencode/prompts/openagent/my-variant.md
```

### Step 2: Edit Metadata

```yaml
---
model_family: oss
recommended_models:
  - ollama/my-model
status: experimental
maintainer: your-name
description: Optimized for my specific use case
---
```

### Step 3: Customize Prompt

Edit the prompt content below the frontmatter for your target model.

### Step 4: Validate

```bash
# Validate the variant exists and metadata is correct
cd evals/framework
npm run eval:sdk -- --agent=openagent --prompt-variant=my-variant --suite=smoke-test
```

### Step 5: Test Thoroughly

```bash
# Run core test suite
npm run eval:sdk -- --agent=openagent --prompt-variant=my-variant --suite=core-tests

# Check results
open ../results/index.html
```

### Step 6: Document Results

Update `.opencode/prompts/openagent/navigation.md` with:
- Test results (pass rate, timing)
- Known issues or limitations
- Recommended use cases

## 🔧 Advanced Usage

### Custom Test Suites

Create custom test suites for your variant:

```bash
# Create suite
cp evals/agents/openagent/config/smoke-test.json \
   evals/agents/openagent/config/my-suite.json

# Edit suite (add your tests)
# Validate suite
cd evals/framework && npm run validate:suites openagent

# Run with your variant
npm run eval:sdk -- --agent=openagent --prompt-variant=my-variant --suite=my-suite
```

See [evals/TEST_SUITE_VALIDATION.md](../../evals/TEST_SUITE_VALIDATION.md) for details.

### Comparing Models

Test the same variant with different models:

```bash
# Test Llama 3.2
npm run eval:sdk -- --agent=openagent --prompt-variant=llama --model=ollama/llama3.2 --suite=core-tests

# Test Qwen 2.5
npm run eval:sdk -- --agent=openagent --prompt-variant=llama --model=ollama/qwen2.5 --suite=core-tests

# Compare results in dashboard
open evals/results/index.html
```

## 📊 Understanding Results

### Dashboard Features

The results dashboard (`evals/results/index.html`) shows:
- ✅ Filter by prompt variant
- ✅ Filter by model
- ✅ Pass/fail rates per variant
- ✅ Test execution times
- ✅ Detailed test results

### Result Files

**Main results** (`evals/results/latest.json`):
```json
{
  "meta": {
    "agent": "openagent",
    "model": "ollama/llama3.2",
    "prompt_variant": "llama",
    "model_family": "llama"
  },
  "summary": {
    "total": 7,
    "passed": 7,
    "failed": 0,
    "pass_rate": 1
  }
}
```

**Per-variant results** (`.opencode/prompts/openagent/results/llama-results.json`):
- Tracks all test runs for this variant
- Shows trends over time
- Helps identify regressions

## 🚀 For Contributors

### Creating a Variant for PR

1. **Create your variant** in `.opencode/prompts/<agent>/<model>.md`
2. **Test thoroughly** with eval framework
3. **Document results** in agent README
4. **Submit PR** with variant file only

### PR Requirements

- ✅ Variant has YAML frontmatter with metadata
- ✅ Variant passes core test suite (≥85% pass rate)
- ✅ Results documented in agent README
- ✅ Agent file unchanged (unless updating default)
- ✅ No `default.md` files in prompts directory
- ✅ CI validation passes

### Validation

```bash
# Validate your variant
cd evals/framework
npm run eval:sdk -- --agent=openagent --prompt-variant=your-variant --suite=core-tests

# Ensure PR uses default
./scripts/prompts/validate-pr.sh
```

## 🎓 Design Principles

### 1. Agent Files are Canonical Defaults
- Agent files (`.opencode/agent/*.md`) are the source of truth
- Tested and production-ready
- Optimized for Claude (primary model)
- Modified through normal PR process

### 2. Variants are Model-Specific Optimizations
- Stored in `.opencode/prompts/<agent>/<model>.md`
- Optimized for specific models/use cases
- May have different trade-offs
- Results documented transparently

### 3. Results are Tracked
- Every test run tracked per variant
- Dashboard shows variant performance
- Easy to compare variants

### 4. Easy to Test
- One command to test any variant
- Automatic model detection
- Results saved automatically

### 5. Safe to Experiment
- Variants don't affect default
- Easy to switch and restore
- Test before committing

## 🆘 Troubleshooting

### Variant Not Found

```bash
# List available variants
ls .opencode/prompts/openagent/*.md

# Check variant exists
npm run eval:sdk -- --agent=openagent --prompt-variant=your-variant --suite=smoke-test
```

### Tests Failing

1. Check variant metadata (YAML frontmatter)
2. Verify recommended model is available
3. Run with debug flag: `--debug`
4. Check results in dashboard

### Model Not Available

```bash
# Check available models
# For Ollama: ollama list
# For OpenRouter: check openrouter.ai/models

# Specify model explicitly
npm run eval:sdk -- --agent=openagent --prompt-variant=llama --model=ollama/llama3.2
```

## 💡 Tips

- **Start with smoke-test** - Fast validation (1 test, ~30s)
- **Use core-tests for thorough testing** - 7 tests, ~5-8min
- **Check dashboard regularly** - Visual feedback on variant performance
- **Document your findings** - Help others by sharing results
- **Test with multiple models** - Same variant may perform differently
