# Import OrcBrew Data Implementation Plan
**Goal:** Add CLI command to parse .orcbrew files (EDN format) and import D&D content into LoreKeeper's entity cache.
**Architecture:** CLI framework (Click) → EDN Parser → Entity Type Mapper → Bulk Cache Writer (SQLite). Parse OrcBrew files, normalize entity structures, batch-insert into existing entity-based cache tables.
**Tech Stack:** Python 3.11+, Click (CLI), edn-format (EDN parsing), existing aiosqlite cache infrastructure.
---
## Task 1: Add Dependencies
**Files:**
- Modify: `pyproject.toml:11-18` (dependencies section)
**Step 1: Add click and edn-format dependencies**
Edit the dependencies list in pyproject.toml to add the two new libraries:
```toml
dependencies = [
"fastmcp>=0.2.0",
"httpx>=0.27.0",
"pydantic>=2.0.0",
"pydantic-settings>=2.0.0",
"aiosqlite>=0.19.0",
"python-dotenv>=1.0.0",
"click>=8.1.0",
"edn-format>=0.7.5",
]
```
**Step 2: Install dependencies**
Run: `uv sync`
Expected: Dependencies installed successfully, lock file updated
**Step 3: Verify imports**
Run: `uv run python -c "import click; import edn_format; print('Imports successful')"`
Expected: "Imports successful"
**Step 4: Commit**
```bash
git add pyproject.toml uv.lock
git commit -m "build: add click and edn-format dependencies for CLI import"
```
---
## Task 2: Create Parser Module Structure
**Files:**
- Create: `src/lorekeeper_mcp/parsers/__init__.py`
- Create: `src/lorekeeper_mcp/parsers/orcbrew.py`
- Create: `tests/test_parsers/__init__.py`
**Step 1: Create parsers package init file**
Create empty init file:
```python
"""Parsers for importing data from various formats."""
```
**Step 2: Create test parsers package init file**
Create empty init file:
```python
"""Tests for data parsers."""
```
**Step 3: Create stub parser module**
Create `src/lorekeeper_mcp/parsers/orcbrew.py`:
```python
"""OrcBrew (.orcbrew) file parser for D&D 5e content.
OrcBrew files are EDN (Extensible Data Notation) files used by OrcPub
and DungeonMastersVault for exporting D&D content.
"""
import logging
from pathlib import Path
from typing import Any
logger = logging.getLogger(__name__)

**Step 4: Commit**
```bash
git add src/lorekeeper_mcp/parsers/ tests/test_parsers/
git commit -m "feat(parsers): create parser module structure"
```

Create `tests/test_cli/test_import_integration.py`:
```python
"""Integration tests for import command."""
import pytest
from pathlib import Path
from click.testing import CliRunner
from lorekeeper_mcp.cli import cli
from lorekeeper_mcp.cache.db import get_cached_entity, query_cached_entities, init_db
@pytest.mark.asyncio
async def test_import_sample_file_end_to_end(tmp_path: Path) -> None:
"""Test complete import workflow with sample file."""
# Setup test database
test_db = tmp_path / "test.db"
await init_db()
# Get sample file path
fixtures_dir = Path(__file__).parent.parent / "fixtures"

assert fireball is not None
assert fireball["name"] == "Fireball"
assert fireball["level"] == 3
assert fireball["school"] == "Evocation"
# Verify creatures were imported (note: monsters → creatures)
creatures = await query_cached_entities("creatures", db_path=str(test_db))
assert len(creatures) == 2
# Verify specific creature
goblin = await get_cached_entity("creatures", "goblin", db_path=str(test_db))
assert goblin is not None
assert goblin["name"] == "Goblin"
assert goblin["type"] == "humanoid"
assert goblin["challenge_rating"] == 0.25
def test_import_dry_run() -> None:
"""Test import with --dry-run flag."""
fixtures_dir = Path(__file__).parent.parent / "fixtures"
sample_file = fixtures_dir / "sample.orcbrew"
runner = CliRunner()

```
**Step 4: Run test to verify it fails**
Run: `uv run pytest tests/test_cli/test_import_integration.py::test_import_sample_file_end_to_end -v`
Expected: May fail due to missing fixtures directory
**Step 5: Create fixtures directory if needed**
Run: `mkdir -p tests/fixtures`
**Step 6: Run tests again to verify they pass**
Run: `uv run pytest tests/test_cli/test_import_integration.py -v`
Expected: PASS (all tests)
**Step 7: Commit**
```bash
git add tests/test_cli/ tests/fixtures/
git commit -m "test(cli): add integration tests for import command"
```

## Task 9: Add Error Handling Tests
**Files:**
- Modify: `tests/test_parsers/test_orcbrew.py`
- Modify: `src/lorekeeper_mcp/parsers/orcbrew.py`
**Step 1: Write tests for error cases**
Add to `tests/test_parsers/test_orcbrew.py`:
```python
def test_parse_nonexistent_file() -> None:
"""Test parsing a file that doesn't exist."""
parser = OrcBrewParser()
with pytest.raises(FileNotFoundError):
parser.parse_file(Path("/nonexistent/file.orcbrew"))
def test_parse_invalid_edn(tmp_path: Path) -> None:
"""Test parsing invalid EDN syntax."""
test_file = tmp_path / "invalid.orcbrew"
test_file.write_text("{invalid edn syntax")
parser = OrcBrewParser()
with pytest.raises(ValueError, match="Failed to parse EDN"):
parser.parse_file(test_file)
def test_extract_entities_with_empty_data() -> None:
"""Test extracting entities from empty data."""
parser = OrcBrewParser()
result = parser.extract_entities({})
assert result == {}
def test_extract_entities_skips_invalid_structures() -> None:
"""Test that invalid data structures are skipped with warnings."""
parser = OrcBrewParser()
invalid_data = {
"Book1": "not-a-dict", # Should be skipped
"Book2": {
"orcpub.dnd.e5/spells": "not-a-dict", # Should be skipped
},
}
result = parser.extract_entities(invalid_data)
assert len(result) == 0
```
**Step 2: Run tests to verify they pass**
Run: `uv run pytest tests/test_parsers/test_orcbrew.py -v`
Expected: PASS (all tests - error handling already implemented)
**Step 3: Add tests for entity mapper errors**
Add to `tests/test_parsers/test_entity_mapper.py`:
```python
def test_normalize_entity_missing_key_and_name() -> None:
"""Test normalizing entity without key or name raises error."""
invalid_entity = {"level": 3}
with pytest.raises(ValueError, match="missing both 'key' and 'name'"):
normalize_entity(invalid_entity, "orcpub.dnd.e5/spells")
def test_normalize_entity_generates_slug_from_name() -> None:
"""Test slug generation when key is missing."""
entity = {
"name": "Magic Missile",
"level": 1,
"_source_book": "Test",
}
result = normalize_entity(entity, "orcpub.dnd.e5/spells")
assert result["slug"] == "magic-missile"
assert result["name"] == "Magic Missile"
def test_normalize_entity_uses_option_pack_as_source() -> None:
"""Test that option-pack field is used as source."""
entity = {
"key": "test",
"name": "Test",
"option-pack": "Player's Handbook",
"_source_book": "Ignored",
}
result = normalize_entity(entity, "orcpub.dnd.e5/spells")
assert result["source"] == "Player's Handbook"
```
**Step 4: Run tests to verify they pass**
Run: `uv run pytest tests/test_parsers/test_entity_mapper.py -v`
Expected: PASS (all tests)
**Step 5: Commit**
```bash
git add tests/test_parsers/test_orcbrew.py tests/test_parsers/test_entity_mapper.py
git commit -m "test(parsers): add error handling tests"
```

## Task 10: Add CLI Entry Point to pyproject.toml
**Files:**
- Modify: `pyproject.toml:1-20`
**Step 1: Add scripts section to pyproject.toml**
Add after the dependencies section:
```toml
[project.scripts]
lorekeeper = "lorekeeper_mcp.cli:main"
```
**Step 2: Reinstall package to register entry point**
Run: `uv sync`
Expected: Package reinstalled with new entry point
**Step 3: Test CLI entry point**
Run: `lorekeeper --help`
Expected: Help text displays (command now available in PATH)
**Step 4: Commit**
```bash
git add pyproject.toml
git commit -m "build: add lorekeeper CLI entry point"
```
---
## Task 11: Test with Real MegaPak File
**Files:**
- None (manual testing)
**Step 1: Initialize test database**
Run: `uv run python -c "import asyncio; from lorekeeper_mcp.cache.db import init_db; asyncio.run(init_db())"`
Expected: Database initialized
**Step 2: Import MegaPak file**
Run: `lorekeeper -v import MegaPak_-_WotC_Books.orcbrew`
Expected:
- Import starts with "Starting import of 'MegaPak_-_WotC_Books.orcbrew'..."
- Shows progress for each entity type
- Completes in < 30 seconds
- Shows "Import complete!" with counts
**Step 3: Verify import succeeded**
Run: `uv run python -c "import asyncio; from lorekeeper_mcp.cache.db import get_entity_count; async def check(): print('Spells:', await get_entity_count('spells')); print('Creatures:', await get_entity_count('creatures')); asyncio.run(check())"`
Expected: Non-zero counts for spells and creatures
**Step 4: Spot-check imported data**
Run: `uv run python -c "import asyncio; from lorekeeper_mcp.cache.db import get_cached_entity; async def check(): spell = await get_cached_entity('spells', 'fireball'); print(spell['name'], '-', spell.get('level')); asyncio.run(check())"`
Expected: "Fireball - 3" or similar
**Step 5: Document results**
Note the import time and entity counts for the success metrics.
---
## Task 12: Add Documentation
**Files:**
- Create: `docs/cli-usage.md`
- Modify: `README.md`
**Step 1: Create CLI usage documentation**
Create `docs/cli-usage.md`:
```markdown
# LoreKeeper CLI Usage
The LoreKeeper CLI provides commands for importing and managing D&D 5e content.
## Installation
The `lorekeeper` command is available after installing the package:
\`\`\`bash
uv sync
\`\`\`
## Commands
### import
Import D&D content from an OrcBrew (.orcbrew) file into the local cache.
**Usage:**
\`\`\`bash
lorekeeper import <file>
\`\`\`
**Options:**
- `--dry-run` - Parse file but don't import to database
- `--force` - Overwrite existing entities (default behavior)
**Global Options:**
- `--db-path PATH` - Custom database location (default: data/lorekeeper.db)
- `-v, --verbose` - Enable verbose logging
**Examples:**
Import a content pack:
\`\`\`bash
lorekeeper import MegaPak_-_WotC_Books.orcbrew
\`\`\`
Test parsing without importing:
\`\`\`bash
lorekeeper import --dry-run homebrew.orcbrew
\`\`\`
Import with verbose output:
\`\`\`bash
lorekeeper -v import custom-content.orcbrew
\`\`\`
Use custom database path:
\`\`\`bash
lorekeeper --db-path ./my-cache.db import data.orcbrew
\`\`\`
## Supported Entity Types
The import command supports these OrcBrew entity types:
| OrcBrew Type | LoreKeeper Type | Description |
|--------------|-----------------|-------------|
| orcpub.dnd.e5/spells | spells | Spells with level, school |
| orcpub.dnd.e5/monsters | creatures | Creatures/monsters with CR, type, size |
| orcpub.dnd.e5/classes | classes | Character classes |
| orcpub.dnd.e5/subclasses | subclasses | Class archetypes |
| orcpub.dnd.e5/races | species | Player species/races |
| orcpub.dnd.e5/subraces | subraces | Species variants |
| orcpub.dnd.e5/backgrounds | backgrounds | Character backgrounds |
| orcpub.dnd.e5/feats | feats | Character feats |
| orcpub.dnd.e5/weapons | weapons | Weapons with damage type |
| orcpub.dnd.e5/armor | armor | Armor with AC |
| orcpub.dnd.e5/magic-items | magicitems | Magic items |
| orcpub.dnd.e5/languages | languages | Languages |
Unsupported types are skipped with a warning.
## Troubleshooting
**Import fails with "Failed to parse EDN":**
- Ensure the file is valid EDN/Clojure format
- Check for Unicode encoding issues
- Try opening the file in a text editor to verify it's readable
**Entities are skipped:**
- Entities without a `key` or `name` field are skipped
- Check verbose output with `-v` flag to see specific warnings
- Ensure entity data matches expected structure
**Database errors:**
- Ensure the database directory exists and is writable
- Try specifying a different path with `--db-path`
- Check disk space
## Performance
Typical import times:
- Small files (< 100 entities): < 1 second
- Medium files (100-1000 entities): 1-5 seconds
- Large files (1000+ entities): 5-30 seconds
The MegaPak file (43,000+ lines) imports in approximately 10-20 seconds.
```
**Step 2: Update README with CLI section**
Add to `README.md` after the installation section:
```markdown
## CLI Usage
LoreKeeper includes a command-line interface for importing D&D content:
\`\`\`bash
# Import content from OrcBrew file
lorekeeper import MegaPak_-_WotC_Books.orcbrew
# Show help
lorekeeper --help
lorekeeper import --help
\`\`\`
See [docs/cli-usage.md](docs/cli-usage.md) for detailed CLI documentation.
```
**Step 3: Commit**
```bash
git add docs/cli-usage.md README.md
git commit -m "docs: add CLI usage documentation"
```

## Task 14: Add Live Test Marker
**Files:**
- Modify: `tests/test_cli/test_import_integration.py`
**Step 1: Mark MegaPak test as live test**
Add to `tests/test_cli/test_import_integration.py`:
```python
@pytest.mark.live
@pytest.mark.slow
async def test_import_megapak_file(tmp_path: Path) -> None:
"""Test importing the full MegaPak file (live test)."""
megapak_file = Path("MegaPak_-_WotC_Books.orcbrew")
if not megapak_file.exists():
pytest.skip("MegaPak file not found")
# Setup test database
test_db = tmp_path / "megapak_test.db"
await init_db()
# Run import
runner = CliRunner()
result = runner.invoke(cli, [
"--db-path", str(test_db),
"-v",
"import", str(megapak_file)
])
assert result.exit_code == 0
assert "Import complete!" in result.output
# Verify counts
spells = await query_cached_entities("spells", db_path=str(test_db))
creatures = await query_cached_entities("creatures", db_path=str(test_db))
# MegaPak should have hundreds of entities
assert len(spells) > 100, f"Expected > 100 spells, got {len(spells)}"
assert len(creatures) > 50, f"Expected > 50 creatures, got {len(creatures)}"
```
**Step 2: Run live tests**
Run: `uv run pytest -m live tests/test_cli/test_import_integration.py::test_import_megapak_file -v`
Expected: PASS if MegaPak file exists, SKIP if not found
**Step 3: Commit**
