shelly

shelly is a skill for Claude Code from HybridAIOne/hybridclaw. It costs 66 tokens per session (3,509 once invoked), scanned A, original, MIT.

A control skill for Shelly smart-home devices, including relays, plugs, lights, covers, shutters, and sensors. Shelly is a brand of connected home and energy devices.

In plain words
What is it for?
Use it to read device status, inspect covers and sensors, control switches and lights, and manage other supported Shelly devices.
Why use it?
It gives an agent a defined way to inspect device state and safely plan or carry out supported controls through local or cloud APIs.

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

shelly scanned grade A with 1 finding 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (shelly.cjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 279 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Shelly

Use this skill for Shelly device inspection and guarded control through the bundled helper. Keep the markdown instructions generic; API-specific request construction belongs in shelly.cjs.

Core Contract

  • Run Shelly HTTP operations through skills/shelly/shelly.cjs. Do not handcraft Shelly URLs or JSON bodies when the helper supports the operation.
  • The helper executes HTTP operations through the HybridClaw gateway, so normal Shelly reads and writes should be a single helper command. Use --request only when an explicit request specification is needed for debugging or code review. For WebSocket planning outputs, use the emitted webSocket object as the complete connection or message specification.
  • Read state before any relay, switch, light, or cover control operation.
  • Treat control operations as amber. Before asking for approval, build an approval-plan for the selected operation and include its approvedHelperCommandText in the approval request. Stop after presenting the plan. Only after the operator confirms in a later message, run that helper command exactly and use its emitted request specification unchanged.
  • Do not perform factory reset, reboot, firmware update, Wi-Fi reset, auth changes, or certificate upload through this skill.

Helper Operations

Use this command surface directly; do not rediscover flags by trial and error. Run node skills/shelly/shelly.cjs --help only when the surface below appears stale. The helper owns the Shelly API method, path, body selection, gateway dispatch, secret injection, and response wrapping. Normal HTTP commands execute the request and return command: "live", the operation, a redacted request summary, and the gateway result. --request emits a request wrapper containing command, operation, stakesTier, and httpRequest without executing it. WebSocket helpers emit webSocket instead of httpRequest. approval-plan emits no httpRequest; it validates an amber command and returns the exact approved helper command to run after confirmation.

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.

shelly is a skill published in the GitHub repository HybridAIOne/hybridclaw (132 stars, last pushed yesterday), licensed MIT. It adds 66 tokens to every session and 3,509 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
