What it does

Electron Live Test is an agent skill from instructa/agent-skills. Live-test any Electron desktop app with native-devtools-mcp, Chrome DevTools Protocol, screenshots, OCR, and accessibility tools. Use when the user asks for Electron UI verification, MCP-driven app control, renderer CDP interaction, native desktop automation, screenshots, or OCR-driven checks.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `README.md`, `agents/openai.yaml` and `references/cdp-targeting.md`).

It sits in Productivity & Automation, covering Browser testing, Desktop control and Mobile testing and debugging. It works with Chrome DevTools and Model Context Protocol. The repository describes itself as: A curated collection of agent-skills.

When your agent uses it

  • The user asks for Electron UI verification
  • MCP-driven app control
  • Renderer CDP interaction
  • Native desktop automation

Example prompts

  • “/electron-live-test”

Requirements

  • Node.js

Workflow steps

9 steps, taken from the first numbered list in SKILL.md.

  1. Confirm native-devtools-mcp is connected.
  2. Confirm the Electron app is running and headed.
  3. Confirm the app exposes CDP on the expected 127.0.0.1: endpoint.
  4. Inspect /json/list and select the existing renderer target.
  5. Take a fresh DOM snapshot before interacting.
  6. Perform one deliberate action at a time.
  7. After clicks, typing, navigation, waits, or anything that can change the page, take a fresh snapshot before the next structural action.
  8. For canvas or native-window interactions, take a screenshot first and explain any coordinate-based action.
  9. Stop and report blockers such as login, missing app window, missing CDP port, missing permissions, unexpected dialogs, wrong target, or…

What it can do on your machine

Read from SKILL.md and the folder at commit d49c149. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx
    • curl
    • sh
    • pnpm
    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, curl, pnpm and npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Electron Live Test loads about 1.3k tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 78 tokens; SKILL.md has 618 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 618 words (~1,272 tokens).

“Use this skill for live, headed testing of a running Electron desktop app. It is for interactive verification while developing, not for replacing automated smoke tests.”
