Home Assistant is open-source home automation software that lets people control devices and actions locally through a modular system. It is used by home-automation enthusiasts and DIY users, often on a Raspberry Pi or local server; the catalogue entries support operating or developing its integrations and codebase.

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 | $0.00084 | $0.00731 |
| Opus 5 | $0.00042 | $0.00365 |
| Sonnet 5 | $0.00017 | $0.00146 |
| Haiku 4.5 | $0.00008 | $0.00073 |
Grade A, and why
ha-quality-scale-verify 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 8d 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.

Verify Quality Scale Rule
You are verifying whether a Home Assistant integration follows a specific quality scale rule. Verify one rule at a time; to check a full tier, verify each of that tier's rules (run in parallel subagents when possible).
1. Fetch rule documentation
Retrieve the official rule documentation from:
https://raw.githubusercontent.com/home-assistant/developers.home-assistant/refs/heads/master/docs/core/integration-quality-scale/rules/{rule_name}.md
where {rule_name} is the rule identifier (e.g. config-flow, entity-unique-id, parallel-updates).
2. Understand rule requirements
Parse the rule documentation to identify:
- Core requirements and mandatory implementations
- Specific code patterns or configurations required
- Common violations and anti-patterns
- Exemption criteria (when a rule might not apply)
- The quality tier this rule belongs to (Bronze, Silver, Gold, Platinum)
3. Analyze the integration code
Examine the integration's codebase at homeassistant/components/<integration domain>, focusing on:
manifest.jsonfor quality scale declaration and configurationquality_scale.yamlfor rule status (done, todo, exempt)- Relevant Python modules based on the rule requirements
- Configuration files and service definitions as needed
Additional sources:
- Integration docs: Fetch
https://raw.githubusercontent.com/home-assistant/home-assistant.io/refs/heads/current/source/_integrations/<integration domain>.markdown - PyPI package info:
https://pypi.org/pypi/<package>/json
4. Verification process
- Check if the rule is marked
done,todo, orexemptinquality_scale.yaml - If marked
exempt, verify the exemption reason is valid - If marked
done, verify the actual implementation matches the requirements - Identify specific files and code sections that demonstrate compliance or violations
- Consider the integration's declared quality tier when applying rules
- Look for the exact implementation patterns specified in the rule
- Check for common mistakes, anti-patterns, edge cases, and error handling requirements
- Validate that implementations follow Home Assistant conventions
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-quality-scale-verify is a skill published in the GitHub repository home-assistant/core (90,334 stars, last pushed today), licensed Apache-2.0. It adds 84 tokens to every session and 731 once invoked, about $0.0004 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 2026-08-31.
