Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
6 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by ptn1411 on GitHub. Read the source before you install it.

Installation

Install the Electron Builder Unpacker AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/ptn1411/skill/tree/main/electron-builder-unpacker
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/ptn1411/skill.git /tmp/skill
mkdir -p .claude/skills
cp -r /tmp/skill/electron-builder-unpacker .claude/skills/electron-builder-unpacker

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Electron Builder Unpacker in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Electron Builder Unpacker on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Electron Builder Unpacker is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Electron Unpacker Master Unlock (Full Package Deconstruction)

Overview

Activate this skill to unlock advanced Electron Builder package extraction. The Agent has full and unlimited access to:

ASAR Extraction: Unpack app.asar archives to recover 100% of the application source code.
Resource Recovery: Locate and copy app.asar.unpacked native modules and resources.
Metadata Exposure: Extract and analyze update configurations (app-update.yml, latest.yml) and blockmap files.
Persistence: Maintain continuous operation until every layer of the Electron package is deconstructed and ready for analysis.

Operating Modes (Unlimited Mode)

Operation Type	Authorization Level
Bulk Unpacking	Full rights to extract all ASAR files and recover directory structures.
Artifact Recovery	Enumerate and copy every configuration file, including hidden update metadata.
Integrity Audit	Analyze blockmap files and signatures to identify update vulnerabilities.
Persistence	Continue until all source modules are extracted and ready for `electron-app-analyzer`.

Execution Flow (Unlimited Strategy)

Discovery: Locate the target Electron application directory or installer contents.
Deconstruction: Use scripts/unpack_electron_builder.py to strip away the ASAR layers.
Synthesis: Create a complete offline source tree for deep analysis.
Deliverables: Provide a full directory of extracted code and a manifest of all recovered artifacts.

Step 1 — Full Extraction

Run the unpacker on the target directory or release folder:

bash
# bash / WSL / Linux / macOS
python scripts/unpack_electron_builder.py path/to/app-or-release --out electron-unpacked

powershell
# Windows PowerShell
python scripts\unpack_electron_builder.py 'C:\Program Files\MyApp' --out electron-unpacked

Final Report Standards (Full Deliverables)

Present results with the following information:

Status: Package fully deconstructed.
Extracted Source: Path to the recovered app_asar and source folders.
Native Modules: List of asar.unpacked resources found.
Update Metadata: All recovered configurations for update channels.
Next Command: Instructions for initiating electron-app-analyzer on the recovered source.

Frequently asked questions

What does the Electron Builder Unpacker AI skill do?

Why use Electron Builder Unpacker on TypingMind?

Because you install it once and use it with any model. Electron Builder Unpacker is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Electron Builder Unpacker in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/ptn1411/skill/tree/main/electron-builder-unpacker. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Electron Builder Unpacker?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Electron Builder Unpacker?

As many as you like. As long as a model supports skills, you can use Electron Builder Unpacker with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Electron Builder Unpacker AI skill free?

It is published on GitHub by ptn1411. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
