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 | $0.00034 | $0.00370 |
| Opus 5 | $0.00017 | $0.00185 |
| Sonnet 5 | $0.00007 | $0.00074 |
| Haiku 4.5 | $0.00003 | $0.00037 |
Grade A, and why
ha-migration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Home Assistant Integration Migration
This skill is an entry point for two distinct migration concerns:
Config Entry Version Migration
When your config entry schema changes (renaming keys, adding required fields), you need to increment VERSION and implement async_migrate_entry.
See ha-config-migration for the full pattern and template.
When to use it: You changed what's stored in entry.data or entry.options and existing users' data needs to be transformed.
Deprecation Fixes
When upgrading to a newer HA version, imports, type annotations, and API patterns that were deprecated may now emit warnings or fail.
See ha-deprecation-fixes for 2024–2025 deprecation patterns with before/after examples.
When to use it: You see deprecation warnings in HA logs, or you're upgrading homeassistant minimum version in hacs.json.
Migration Checklist (Per Version Upgrade)
-
Check the Home Assistant Developer Blog for breaking changes
-
Search for deprecated imports in your code
-
Run
check-patterns.pyto detect common issues:python3 "${CLAUDE_PLUGIN_ROOT}/scripts/check-patterns.py" custom_components/my_integration/ -
Update minimum HA version in
hacs.json -
Test against target HA version

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.
- 3d ago First seen · 44 lines · 34 tokens per session scan A 1f2200c8b015
ha-migration is a skill published in the GitHub repository L3DigitalNet/Claude-Code-Plugins (6 stars, last pushed 3d ago), licensed MIT. It adds 34 tokens to every session and 370 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.
