A Claude skill that enforces a disciplined "prove it before you patch it" workflow for debugging — instead of guess-and-check fixes that patch symptoms and let the real bug resurface later.

# Clone the repository
git clone https://github.com/ParthVitnor/root-cause-debugger.git

# Copy to your Claude skills directory
cp -r root-cause-debugger ~/.claude/skills/root-cause-debugger

Then reload skills:

# In a Claude Code session
/skill refresh

Verify Installation

# Check the skill is recognized
/skill list | grep root-cause-debugger

Prerequisites

Claude Code CLI — Install Guide
Git — Required for evidence collection and bisect scripts
Bash — The helper scripts are POSIX shell scripts

Quick Start

Once installed, invoke the skill when debugging:

# In a Claude Code session
/skill root-cause-debugger

Then describe your problem:

"Test test_user_login fails intermittently with a timeout"
"error spike: 500s on /api/checkout since deploy abc123"
"Getting this stack trace when I run npm test"

The skill walks you through a 5-stage workflow, running helper scripts to collect evidence, bisect culprits, and scan for quality issues.
