Brandon Martin 2232aae10c fix(plugins): remove unsupported manifest path fields (#7)
## 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`

    def __init__(self, coordinator: MyCoordinator, device_id: str) -> None:
        """Initialize child device."""
        super().__init__(coordinator)
        self._attr_device_info = DeviceInfo(
            identifiers={(DOMAIN, device_id)},

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:

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

strings.json:

{
  "config": {
    "step": {
      "user": {
        "title": "Connect to Device",
        "description": "Enter your device credentials",
        "data": {
          "host": "Hostname or IP address",
          "username": "Username",
          "password": "Password"
        }
      },
      "reauth_confirm": {
        "title": "Reauthenticate",
        "description": "Your credentials have expired. Please enter your password.",
        "data": {
          "password": "Password"
        }
      }
    },
    "error": {
      "cannot_connect": "Unable to connect to the device",
      "invalid_auth": "Invalid credentials",
      "unknown": "Unexpected error occurred"
    },
    "abort": {
      "already_configured": "Device is already configured"
    }
  },
  "options": {
    "step": {
      "init": {
        "title": "Options",
        "data": {
          "scan_interval": "Update interval (seconds)"
        }
      }
    }
  },
  "entity": {
    "sensor": {
      "temperature": {
        "name": "Temperature"
      },
      "energy": {
        "name": "Energy consumption"
      }
    }
  }
}

Instructions

When invoked, you MUST follow these steps:

  1. 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)
  2. Create Integration Structure

    • Generate manifest.json with correct metadata
    • Create __init__.py with setup/unload hooks
    • Create const.py for domain and constants
    • Add config_flow.py if UI configuration is needed
  3. 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
  4. 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
  5. Add Translations

    • Create strings.json with config flow messages
    • Add entity translations with translation_key
    • Include error and abort messages
  6. 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 = True for 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 @property methods when values are computed from coordinator data
