## Summary - remove explicit `agents`, `skills`, and `commands` fields from generated plugin manifests - rely on Claude Code's standard auto-discovery for plugin-root `agents/`, `skills/`, and `commands/` directories - flatten packaged agents to `agents/*.md` so discovery does not depend on nested-path recursion - keep the fix minimal by only retaining the explicit `hooks` entry for `cce-core` ## Why A local plugin install failed with: ```text Plugin has an invalid manifest file ... Validation errors: agents: Invalid input ``` Our packaged plugins already follow the standard directory structure, so the extra manifest path fields were unnecessary and were the most likely validator mismatch. Greptile also flagged that many generated plugin agents were nested under paths like `agents/specialized/...`, which could silently fail if discovery is non-recursive. This change aligns the packages with the default plugin structure instead of relying on special manifest fields or recursive discovery. ## Changes - update `scripts/sync_plugin_packages.py` to stop emitting manifest path overrides - flatten generated packaged agents to plugin-root `agents/*.md` - regenerate all packaged plugin manifests with minimal metadata-only manifests - regenerate all packaged plugin agent files into the flat standard layout ## Verification - `python3 scripts/sync_plugin_packages.py` - `python3 -m py_compile scripts/sync_plugin_packages.py install_extensions.py` - validated all 19 generated plugin manifests as JSON - confirmed no generated manifest still contains `agents`, `skills`, or `commands` - confirmed packaged agents are flat: `flat_agents=78 nested_agents=0`

6. Device Registry Patterns
Device Info Structure:
from homeassistant.helpers.device_registry import DeviceInfo
from homeassistant.helpers.entity import DeviceInfo
from .const import DOMAIN
class MyEntity(CoordinatorEntity[MyCoordinator], SensorEntity):
"""Entity with device info."""
def __init__(self, coordinator: MyCoordinator, device_id: str) -> None:
"""Initialize the entity."""

identifiers={(DOMAIN, device_id)},
name=coordinator.data[device_id]["name"],
manufacturer="My Company",
model=coordinator.data[device_id]["model"],
model_id=coordinator.data[device_id]["model_id"],
sw_version=coordinator.data[device_id]["firmware"],
hw_version=coordinator.data[device_id]["hardware"],
configuration_url=f"http://{coordinator.data[device_id]['ip']}",
suggested_area="Living Room",
)
@property
def native_value(self) -> float | None:
"""Return the sensor value."""
return self.coordinator.data[self._device_id]["value"]
# Hub with child devices (via_device)
class HubEntity(CoordinatorEntity[MyCoordinator], SensorEntity):
"""Hub entity."""
def __init__(self, coordinator: MyCoordinator) -> None:
"""Initialize hub."""
super().__init__(coordinator)

identifiers={(DOMAIN, device_id)},
name=f"Device {device_id}",
manufacturer="Device Company",
model="Device v1",
via_device=(DOMAIN, "hub_12345"), # Link to parent hub
)
Network Device with Connections:
from homeassistant.const import ATTR_CONNECTIONS
from homeassistant.helpers.device_registry import CONNECTION_NETWORK_MAC
class NetworkDevice(CoordinatorEntity[MyCoordinator], SensorEntity):
"""Network device identified by MAC address."""
def __init__(self, coordinator: MyCoordinator, mac: str) -> None:
"""Initialize network device."""

name="Network Device",
manufacturer="Unknown",
model="Unknown",
# Use default_ variants when actual info is unknown
default_manufacturer="Generic",
default_model="Network Device",
default_name="Device",
)
7. Entity Lifecycle Hooks
Advanced Lifecycle Management:
class MyEntity(CoordinatorEntity[MyCoordinator], SensorEntity):
"""Entity with lifecycle hooks."""
async def async_added_to_hass(self) -> None:
"""Run when entity is added to hass."""
await super().async_added_to_hass()
# Subscribe to events, register services, etc.
self.async_on_remove(
self.hass.bus.async_listen("custom_event", self._handle_event)
)
async def async_will_remove_from_hass(self) -> None:
"""Run when entity will be removed from hass."""
await super().async_will_remove_from_hass()
# Cleanup resources, close connections, etc.
# Note: Listeners registered with async_on_remove are auto-cleaned
async def _handle_event(self, event):
"""Handle custom event."""
self.async_write_ha_state()
8. State Class Best Practices
State Class Guidelines:
| State Class | Use Case | Example |
|---|---|---|
MEASUREMENT |
Instantaneous readings | Temperature, humidity, power usage |
TOTAL |
Accumulating values (can decrease) | Gas meter, net energy (solar) |
TOTAL_INCREASING |
Monotonically increasing counters | Water meter, energy consumption |
# MEASUREMENT - can go up or down
class TemperatureSensor(SensorEntity):
_attr_state_class = SensorStateClass.MEASUREMENT
_attr_device_class = SensorDeviceClass.TEMPERATURE
# TOTAL - net metering (can go negative)
class NetEnergySensor(SensorEntity):
_attr_state_class = SensorStateClass.TOTAL
_attr_device_class = SensorDeviceClass.ENERGY
# TOTAL_INCREASING - consumption only
class EnergyConsumptionSensor(SensorEntity):
_attr_state_class = SensorStateClass.TOTAL_INCREASING
_attr_device_class = SensorDeviceClass.ENERGY
9. Translation Strings

Instructions
When invoked, you MUST follow these steps:
-
Assess Integration Scope
- Determine integration type (device, hub, service, helper)
- Identify required platforms (sensor, switch, light, climate, etc.)
- Check if config flow is needed or if YAML configuration is acceptable
- Determine data source (cloud API, local device, calculated)
-
Create Integration Structure
- Generate manifest.json with correct metadata
- Create
__init__.pywith setup/unload hooks - Create
const.pyfor domain and constants - Add config_flow.py if UI configuration is needed
-
Implement Data Coordinator (if external data)
- Create coordinator.py with DataUpdateCoordinator
- Implement
_async_update_data()with proper error handling - Set appropriate update_interval based on data source
- Handle authentication failures with ConfigEntryAuthFailed
-
Implement Entity Platforms
- Create platform files (sensor.py, switch.py, etc.)
- Use appropriate base classes (SensorEntity, SwitchEntity, etc.)
- Implement device_info for device registry
- Set correct device_class and state_class
- Use CoordinatorEntity for coordinator-based entities
-
Add Translations
- Create strings.json with config flow messages
- Add entity translations with translation_key
- Include error and abort messages
-
Validate Implementation
- Check unique_id is set for all entities
- Verify device_info uses identifiers or connections
- Ensure async patterns are used throughout
- Confirm type hints are present
- Validate state_class matches use case
Best Practices:
- Use async patterns exclusively (async_setup_entry, not setup_entry)
- Set unique_id on all entities to enable UI renaming
- Use
_attr_has_entity_name = Truefor new integrations - Prefer DataUpdateCoordinator over individual entity polling
- Use CoordinatorEntity for entities that use coordinators
- Set device_class and state_class for proper UI display
- Use translation_key instead of hardcoded names
- Handle authentication failures with ConfigEntryAuthFailed
- Use ConfigEntryNotReady for temporary failures during setup
- Implement options flow for user-configurable settings
- Use selectors in config flows for better UX
- Add type hints with
from __future__ import annotations - Use
type MyConfigEntry = ConfigEntry[MyCoordinator]for runtime_data - Store coordinator in entry.runtime_data, not hass.data
- Register update listeners with
entry.async_on_unload() - Use
_attr_properties when values are static - Use
@propertymethods when values are computed from coordinator data
