Prereq Doctor

Diagnoses missing CLI tools and Python dependencies, offers to install them.

When to Use

PostToolUseFailure hook detects a missing-tool error pattern

Setup needs to validate a selected integration (issue tracker, CLI tool)

Any command fails with "command not found" or "ModuleNotFoundError"

User asks to check or install prerequisites

How It Works

Diagnose: Parse the error or tool name to identify what's missing

Lookup: Match against the known tool registry (see refs/tool-registry.md)

Detect platform: macOS (brew) vs Linux (apt/dnf) vs generic (pip/npm/cargo)

Ask: Present the install command and ask the user for permission

Install: Run the install command if approved

Verify: Confirm the tool is now available

Quick Reference

# Diagnose a specific tool sh "${CLAUDE_PLUGIN_ROOT}/scripts/_python.sh" "${CLAUDE_PLUGIN_ROOT}/scripts/platform/prereq_doctor.py" check <tool> # Diagnose from an error message sh "${CLAUDE_PLUGIN_ROOT}/scripts/_python.sh" "${CLAUDE_PLUGIN_ROOT}/scripts/platform/prereq_doctor.py" diagnose "<error_text>" # Check all prerequisites for wicked-garden sh "${CLAUDE_PLUGIN_ROOT}/scripts/_python.sh" "${CLAUDE_PLUGIN_ROOT}/scripts/platform/prereq_doctor.py" check-all

Usage from Commands

Commands should NOT inline install logic. Instead:

Skill(skill="wicked-garden:platform:prereq-doctor", args="check gh")

Or let the PostToolUseFailure hook catch it automatically — just try to use the tool.
