 Octohook is a Python library that simplifies working with GitHub Webhooks by parsing incoming payloads into typed Python classes. It provides automatic payload parsing, URL interpolation helpers, and a decorator-based system for registering webhook handlers.
 
-## Development Commands
+## Key Concepts
 
-### Testing
-```bash
-# Run all tests
-uv run pytest
+### Hook System
 
-# Run with verbose output
-uv run pytest -v
-```
+The hook system uses a three-level filtering mechanism:
 
-### Building
-```bash
-# Build the package
-uv build
-```
+1. **Event filtering** - Match on `WebhookEvent` (e.g., PULL_REQUEST, LABEL)
+2. **Action filtering** - Match on `WebhookEventAction` (e.g., OPENED, CLOSED) or `ANY_ACTION` (*)
+3. **Repository filtering** - Match specific repo full_name or `ANY_REPO` (*)
+
+**Handler resolution order:**
+1. If any debug hooks exist for the event, ONLY debug hooks run
+2. Otherwise: handlers for (event, specific_action, ANY_REPO) + (event, specific_action, specific_repo) + (event, ANY_ACTION, ANY_REPO)
+
+**Execution behavior:**
+- Handlers run sequentially in registration order
+- Exceptions are logged but don't stop execution
+- Debug mode (`debug=True` on any hook) causes only debug hooks to fire for that event
+
+### Payload Handling
+
+GitHub sends different payload structures for the same model depending on the event type and action. For example:
+- `changes` key is only present for some actions with "edited" events
+- Not all fields are populated in all contexts
+
+Octohook uses `Optional` types extensively to handle missing fields gracefully. Models conform to the "least common denominator" - required fields are only those present in ALL payloads for that model.
 
 ## Architecture
 
-### Core Components
+### Module Organization
 
-**octohook/__init__.py** - Entry point providing:
-- `setup(modules)` - Configures octohook by loading webhook handlers. Raises on import errors. Always calls reset() first to clear existing state.
-- `reset()` - Clears all registered hooks and imported modules. Returns octohook to unconfigured state.
+**octohook/__init__.py** - Entry point
+- `setup(modules)` - Configures octohook by loading webhook handlers. Raises on import errors. Always calls reset() first.
+- `reset()` - Clears all registered hooks and imported modules
 - `OctohookConfigError` - Exception raised for configuration errors
 - Exports: `hook`, `handle_webhook`, `parse`, `setup`, `reset`, `WebhookEvent`, `WebhookEventAction`, `OctohookConfigError`
 
-**octohook/decorators.py** - Decorator system (`_WebhookDecorator` class):
-- `@hook(event, actions, repositories, debug)` - Registers functions as webhook handlers
+**octohook/decorators.py** - Decorator system
+- `@hook` decorator - Registers functions as webhook handlers
 - `handle_webhook(event_name, payload)` - Dispatches webhooks to registered handlers
-- Handler storage: nested defaultdicts organized by event → action → repo → handlers
-- Debug mode: when `debug=True` on any hook, only debug hooks fire for that event
-- Sequential execution: handlers run in order, exceptions are logged but don't stop execution
+- `_WebhookDecorator` class - Manages handler registration and routing
 
-**octohook/events.py** - Event classes:
+**octohook/events.py** - Event classes
 - `BaseWebhookEvent` - Base class with common fields (sender, repository, organization, enterprise)
-- 40+ specific event classes (e.g., `PullRequestEvent`, `IssuesEvent`, `LabelEvent`)
-- `WebhookEvent` enum - All GitHub event types (check_run, pull_request, etc.)
-- `WebhookEventAction` enum - All GitHub actions (opened, closed, synchronize, etc.)
+- Specific event classes (e.g., `PullRequestEvent`, `IssuesEvent`, `LabelEvent`)
+- `WebhookEvent` enum - All GitHub event types
+- `WebhookEventAction` enum - All GitHub actions
 - `parse(event_name, payload)` - Factory function that returns appropriate event object
 
-**octohook/models.py** - Model classes:
+**octohook/models.py** - Model classes
 - `BaseGithubModel` - Base class for all GitHub models
 - Core models: `User`, `Repository`, `PullRequest`, `Issue`, `Comment`, etc.
-- URL interpolation: Many models have methods like `archive_url(format, ref)` that fill in URL templates
-- `_transform(url, local_variables)` - Helper that replaces `{param}` and `{/param}` patterns in URLs
-- `_optional(payload, key, class_type)` - Helper for nullable fields
+- URL interpolation helpers that fill in URL templates with parameters
 
-### Hook System
+## Development
 
-The hook system uses a three-level filtering mechanism:
+### Testing
 
-1. **Event filtering** - Match on `WebhookEvent` (e.g., PULL_REQUEST, LABEL)
-2. **Action filtering** - Match on `WebhookEventAction` (e.g., OPENED, CLOSED) or `ANY_ACTION` (*)
-3. **Repository filtering** - Match specific repo full_name or `ANY_REPO` (*)
+```bash
+# Run all tests
+uv run pytest
 
-Handler resolution order:
-1. If any debug hooks exist for the event, ONLY debug hooks run
-2. Otherwise: handlers for (event, specific_action, ANY_REPO) + (event, specific_action, specific_repo) + (event, ANY_ACTION, ANY_REPO)
+# Run with verbose output
+uv run pytest -v
+```
 
-### Payload Inconsistencies
+**Test organization:**
+- Tests use `pytest` and `pytest-mock`
+- Test fixtures in `tests/fixtures/complete/` contain real GitHub webhook payloads
+- Hook tests verify decorator system routing
+- Model tests verify parsing and URL interpolation
+- `tests/conftest.py` provides autouse fixture that calls `reset()` before/after each test for isolation

+## Documentation Standards
 
-## Testing Notes
+### Code Documentation
 
-- Tests use `pytest` and `pytest-mock`
-- Test fixtures in `tests/fixtures/complete/` contain real GitHub webhook payloads
-- Hook tests verify that the decorator system correctly routes events to handlers
-- Model tests verify parsing and URL interpolation
-- `tests/conftest.py` provides an autouse fixture that calls `reset()` before/after each test for isolation
-- The autouse fixture also clears test module imports from `sys.modules` to ensure decorators re-register on each test
+**Public API functions** (exported in `__all__`):
+- Google-style docstrings with Args, Raises, Example sections
+- Include at least one runnable usage example
+- Type hints required on all signatures
+
+### User Documentation
+
+**Tone:**
+- Direct and technical - assume reader competence
+- No marketing language or superlatives
+- Imperative mood for instructions
+- Explain "why" before "how"
+
+**Content:**
+- Show real, runnable examples first
+- Link to external docs rather than duplicating them
+- Keep explanations concise
