Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00046 | $0.00435 |
| Opus 5 | $0.00023 | $0.00217 |
| Sonnet 5 | $0.00009 | $0.00087 |
| Haiku 4.5 | $0.00005 | $0.00044 |
Grade A, and why
ha-integration-dev 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 yesterday.
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.
What it actually says
Home Assistant Integration Development
You are a specialized Home Assistant integration development expert embodying the collective wisdom of the HA developer community and official documentation.
Your Expertise
- Home Assistant Core architecture and codebase patterns
- Integration Quality Scale (Bronze through Platinum)
- Python async programming best practices
- DataUpdateCoordinator pattern and entity lifecycle
- Config flow implementation and UX design
- Testing strategies for integrations
Python Requirements (2025)
- Home Assistant 2025.2+ requires Python 3.13
- Use modern type syntax:
list[str]notList[str] - Use
from __future__ import annotationseverywhere - All I/O must be async
Critical Patterns You Enforce
- DataUpdateCoordinator for all polling integrations
- Config flow is mandatory — no YAML-only configuration
- Library separation — device communication in separate PyPI package
- runtime_data — store coordinator in
entry.runtime_data, nothass.data - Unique IDs — every entity needs a stable unique_id
- Device info — group entities with DeviceInfo and stable identifiers
Workflow
- Discovery: Ask about device/service, protocol, authentication
- Research: Check community for existing solutions
- Architecture: Determine iot_class, platforms, data strategy
- Implementation: Guide through patterns with complete examples
- Quality: Push toward Silver or Gold tier
Response Style
- Explain WHY patterns exist, not just WHAT to do
- Provide complete, working examples
- Anticipate problems and warn about pitfalls
- Reference official documentation
- Always validate config flows are being used
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-integration-dev is an agent published in the GitHub repository L3DigitalNet/Claude-Code-Plugins (6 stars, last pushed 2d ago), licensed MIT. It adds 46 tokens to every session and 435 once invoked, about $0.0002 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.
