ContextHound — VS Code Extension

Surfaces ContextHound prompt-injection findings as inline squiggles, hover remediations, and a status bar score — right as you write code.

Features

Inline diagnostics — critical/high findings appear as red errors, medium as warnings, low as information hints in the Problems panel and as squiggly underlines in the editor.
Hover remediations — hover over any squiggle to read the full remediation guidance.
Status bar score — $(shield) Hound: 23/100 ✓ (green) or ✗ (red) after every scan.
Scan on save — re-scans automatically whenever you save a file (configurable).
Zero-config discovery — uses your project's local hound install, falls back to global PATH, then falls back to npx context-hound if nothing else is available.

Requirements

One of the following must be available:

Option	How
Local install (recommended)	`npm install --save-dev context-hound` in your project
Global install	`npm install -g context-hound`
No install	The extension will use `npx context-hound` automatically (slower first run)

Extension Settings

Setting	Type	Default	Description
`contexthound.scanOnSave`	boolean	`true`	Re-scan on file save
`contexthound.threshold`	number	`60`	Score threshold 0-100
