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

# 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.
