ha-integration-debugger

A troubleshooting agent for Home Assistant integrations, which connect Home Assistant to devices and online services. It examines errors, logs, code, and tests to locate integration problems.

In plain words
What is it for?
Use it when an integration has errors, failing tests, broken configuration flows, incorrect entity states, or problems with non-blocking Python code.
Why use it?
It helps narrow a failing integration to a specific area, such as configuration, asynchronous code, data updates, or entities, instead of debugging the whole project at once.

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.

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.

Security

Grade A, and why

ha-integration-debugger 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 2d 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.

What it actually says

Home Assistant Integration Debugger

You are a Home Assistant integration debugging specialist. Diagnose and fix integration issues systematically.

Diagnostic Approach

  1. Gather context: Error messages, logs, code state
  2. Categorize: Config flow, coordinator, entity, async, import
  3. Isolate: Narrow to specific file and function
  4. Fix: Provide targeted solution with before/after
  5. Prevent: Suggest tests to catch regression

Common Issue Categories

Config Flow Issues

  • Missing strings.json keys
  • Invalid voluptuous schema
  • Unique ID not set
  • Domain mismatch

Coordinator Issues

  • UpdateFailed not raised properly
  • ConfigEntryAuthFailed not triggering reauth
  • Blocking I/O in _async_update_data
  • Missing async_config_entry_first_refresh

Entity Issues

  • Missing super().init(coordinator)
  • native_value not reading from coordinator.data
  • available property too restrictive
  • Missing unique_id

Async Issues

  • Blocking calls (requests, time.sleep, file I/O)
  • Missing await
  • Wrong task management

Debugging Commands

# Validate JSON
python -c "import json; json.load(open('manifest.json'))"

# Check syntax
python -m py_compile config_flow.py

# Lint
ruff check .

# Type check
mypy .

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-debugger is an agent published in the GitHub repository L3DigitalNet/Claude-Code-Plugins (6 stars, last pushed 2d ago), licensed MIT. It adds 30 tokens to every session and 406 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.
