vscode-ext-context

description

Extract raw source code context around a specific VSCode extension command's registerCommand call. Outputs the surrounding N characters of minified code for manual inspection. Use when the user wants to see the actual source code around a command registration, needs to understand the internal implementation details that automated analysis missed, or wants to trace how a command interacts with other parts of the extension. This is the low-level "grep" equivalent — for structured analysis, use analyze-params instead.

Extract VSCode Extension Command Context

Get raw source code around a command's registerCommand for manual analysis.

Usage

# Extract context for a specific command
python3 scripts/extract_context.py <extension-id> <command-name> [--chars 1500]

# Extract context for a keyword (not just commands)
python3 scripts/extract_context.py <extension-id> --keyword "handleUri" [--chars 2000]

# Search for any pattern in extension.js
python3 scripts/extract_context.py <extension-id> --pattern "sendText.*true" [--chars 500]

What It Does

Reads the extension's minified extension.js and extracts surrounding characters around:

• A specific registerCommand("name" call
• A keyword occurrence
• A regex pattern match

This is the "escape hatch" for when automated analysis doesn't capture enough detail. Use it to:

• See the full function body of a command handler
• Trace how parameters flow through internal functions
• Find related patterns (e.g., all sendText calls to determine auto-send behavior)
• Inspect URI handler implementations
