Security

Grade A, and why

home-assistant 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 1mo 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

{
  "name": "home-assistant",
  "version": "1.0.0",
  "description": "Control and query Home Assistant smart home devices via the REST API. Use this skill whenever the user mentions Home Assistant, smart home control, IoT devices, home automation, turning lights on/off, checking sensor readings, thermostat control, door locks, or any task involving their home's connected devices — even if they don't explicitly say \"Home Assistant.\" Also trigger when users ask about their home's state, want to create automations, or reference entity IDs like \"light.living_room\" or \"switch.garage_door.\""

Contents

What it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 108 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

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.
