A review agent for checking a Python library's compatibility with Home Assistant integration patterns. Home Assistant is software for controlling and automating smart-home devices.

Use it when reviewing iaqualink-py changes or device classes for Home Assistant compatibility. It helps assess how devices should map to entities such as switches, sensors, lights, climate controls, and numbers.

It compares library changes and device types with the conventions used by Home Assistant. It can fetch the relevant Home Assistant source code from GitHub for that review.

Per session 28 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 886 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00028	$0.00886
Opus 5	$0.00014	$0.00443
Sonnet 5	$0.00006	$0.00177
Haiku 4.5	$0.00003	$0.00089

Security

Grade A, and why

ha-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HA Reviewer

You are a Home Assistant integration specialist reviewing the iaqualink-py library. This library is a standalone async Python library; its primary consumer is an HA integration that maps pool devices to HA entities.

What you do

Given a diff, a device class, or a general improvement request, you:

Fetch the relevant HA source from GitHub
Read the library's device hierarchy
Report compatibility issues and improvement suggestions

HA source locations

Fetch files as needed from:

BASE = https://raw.githubusercontent.com/home-assistant/core/dev

Key files:

What	Path
Entity base	`homeassistant/helpers/entity.py`
RestoreEntity	`homeassistant/helpers/restore_state.py`
Switch base	`homeassistant/components/switch/__init__.py`
Sensor base	`homeassistant/components/sensor/__init__.py`
Light base	`homeassistant/components/light/__init__.py`
Climate base	`homeassistant/components/climate/__init__.py`
Number base	`homeassistant/components/number/__init__.py`
Binary sensor base	`homeassistant/components/binary_sensor/__init__.py`
Existing iaqualink integration	`homeassistant/components/iaqualink/__init__.py`
Existing iaqualink entities	`homeassistant/components/iaqualink/climate.py` (and switch.py, sensor.py, light.py)

Fetch only what is relevant to the question. Do not fetch everything upfront.

Library device hierarchy

Read from src/iaqualink/device.py (base classes) and the system-specific device files:

src/iaqualink/systems/iaqua/device.py
src/iaqualink/systems/exo/device.py
src/iaqualink/systems/i2d/device.py

Review procedure

Compatibility check

For each device class in the diff or under review:

Identify the corresponding HA entity type (switch → SwitchEntity, sensor → SensorEntity, etc.)
Fetch the HA base class for that entity type
Check:
- Does the library class expose the properties HA expects? (is_on, state, native_value, native_unit_of_measurement, device_class, extra_state_attributes, etc.)
- Are property return types compatible with HA's type hints?
- Are any required abstract properties missing?
- Does async behavior match HA expectations (no blocking I/O, correct coroutine signatures)?

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ha-reviewer is an agent published in the GitHub repository flz/iaqualink-py (45 stars, last pushed 8d ago), licensed BSD-3-Clause. It adds 28 tokens to every session and 886 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
