Diagnosis Mode

When dependencies are broken, run diagnosis:

Common Issues & Fixes

Emergency Fixes

# Node.js - Nuclear reset
rm -rf node_modules package-lock.json
npm cache clean --force
npm install

# Python - Clean virtualenv
rm -rf venv
python -m venv venv
source venv/bin/activate
pip install -r requirements.txt

# Go - Reset modules
rm go.sum
go mod tidy

---

Security Audit

Run security checks for any project:

# Node.js
npm audit
npm audit --json | jq '.metadata.vulnerabilities'

# Python
pip-audit
safety check

# Go
govulncheck ./...

# Rust
cargo audit

# Ruby
bundle audit

# .NET

Verification Checklist

After updates:

• Updates scanned without errors
• MINOR/PATCH auto-applied
• MAJOR updates prompted individually
• Fixed versions untouched
• Lock file updated
• Install command ran
• Security audit passed (or issues noted)

<details> <summary><strong>Deep Dive: Project Detection</strong></summary>

The skill auto-detects project type by scanning for package files:

Detection order matters for monorepos:

1. Check current directory first
2. Then check for workspace/monorepo patterns
3. Offer to run recursively if applicable

</details> <details> <summary><strong>Deep Dive: Node.js with taze</strong></summary>

Prerequisites

# Install taze globally (recommended)
npm install -g taze

# Or use npx
npx taze

Smart Update Flow

# 1. Scan all updates
taze

# 2. Apply safe updates (minor + patch)
taze minor --write

# 3. For each major, prompt user:
#    "Update @types/node from ^20.0.0 to ^22.0.0?"
#    If yes, add to approved list

# 4. Apply approved majors
taze major --write --include approved-pkg1,approved-pkg2

# 5. Install
npm install  # or pnpm install / yarn

Auto-Approve List

Some packages have frequent major bumps but are backward-compatible:

</details> <details> <summary><strong>Deep Dive: Version Strategies</strong></summary>

Semantic Versioning

MAJOR.MINOR.PATCH (e.g., 2.3.1)

MAJOR: Breaking changes - requires code changes
MINOR: New features - backward compatible
PATCH: Bug fixes - backward compatible

Range Specifiers

Recommended Strategy

{
  "dependencies": {
    "critical-lib": "1.2.3",      // Exact for critical
    "stable-lib": "~1.2.3",       // Patch only for stable
    "modern-lib": "^1.2.3"        // Minor OK for active
  }
}

</details> <details> <summary><strong>Deep Dive: Conflict Resolution</strong></summary>

Node.js Conflicts

Diagnosis:

npm ls package-name      # See dependency tree
npm explain package-name # Why installed
yarn why package-name    # Yarn equivalent

Resolution with overrides:

// package.json
{
  "overrides": {
    "lodash": "^4.18.0"
  }
}

Resolution with resolutions (Yarn):

{
  "resolutions": {
    "lodash": "^4.18.0"
  }
}

Python Conflicts

Diagnosis:

pip check
pipdeptree -p package-name

Resolution:

# Use virtual environment
python -m venv venv
source venv/bin/activate
pip install -r requirements.txt

# Or use constraints
pip install -c constraints.txt -r requirements.txt
