# create-pdf-fixture
Generate complete PDF test fixtures that combine:
- **Proper ReportLab tables** via `create-table` (detectable by Marker/Camelot)
- **AI-generated images** via `create-image` (diagrams, decorative elements)
- **Text content** with various formatting challenges
## Why This Exists
Creating test PDFs that properly exercise extractors requires:
1. Tables built with ReportLab (not raw drawing commands)
2. Images that test VLM classification (decorative vs data)
3. Edge cases: empty sections, malformed titles, nested structures
This skill orchestrates sibling skills for modular, reusable fixtures.
## Quick Start
```bash
cd .pi/skills/create-pdf-fixture
# Generate the extractor bug reproduction fixture
uv run generate.py extractor-bugs --output test.pdf
# Generate a simple fixture
uv run generate.py simple --output simple_test.pdf
# List available presets
uv run generate.py list-presets
# Verify table detection
uv run generate.py verify test.pdf
```
## Presets
| Preset | Description | Tests |
|--------|-------------|-------|
| `extractor-bugs` | Reproduces known extractor issues | Empty sections, false tables, malformed titles |
| `simple` | Basic PDF with table and text | Basic extraction |
## Sibling Skills Used
| Skill | Purpose |
|-------|---------|
| `create-table` | Creates ReportLab tables (Marker-detectable) |
| `create-image` | AI-generated images with caching |
Cached images from `create-image/cached_images/`:
- `decorative.png` - Cover illustration
- `flowchart.png` - Process diagram
- `network_arch.png` - Architecture diagram
## Legacy Usage (Still Supported)
```bash
# Via wrapper (uses extractor project)
./run.sh --example --name test_fixture
./run.sh --spec content_spec.json --name my_fixture
```
## JSON Spec Format (Legacy)
```json
{
"style": "standard",
"sections": [
{
"title": "1. Requirements",
"level": 1,
"content": [
{"type": "text", "text": "This document describes requirements."},
{"type": "table", "columns": ["ID", "Name"], "rows": [["1", "Alice"]]},
{"type": "figure", "description": "Architecture diagram"}
]
}
]
}
```
## Output
- `extractor_bugs_fixture.pdf` - Cached in `cached_fixtures/`
- Custom output via `--output` flag
## Dependencies
```toml
dependencies = [
"pymupdf>=1.23.0",
"reportlab>=4.0.0",
