Diagnosis Mode

When dependencies are broken, run diagnosis:

Common Issues & Fixes

Issue	Symptoms	Fix
Version Conflict	"Cannot resolve dependency tree"	Clean install, use overrides/resolutions
Peer Dependency	"Peer dependency not satisfied"	Install required peer version
Security Vuln	npm audit shows issues	npm audit fix or manual update
Unused Deps	Bloated bundle	Run depcheck (Node) or equivalent
Duplicate Deps	Multiple versions installed	Run npm dedupe or equivalent

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
dotnet list package --vulnerable

Severity Response

Severity	Action
Critical	Fix immediately
High	Fix within 24h
Moderate	Fix within 1 week
Low	Fix in next release

---

Anti-Patterns

Avoid	Why	Instead
Update fixed versions	Intentionally pinned	Skip them
Auto-apply MAJOR	Breaking changes	Prompt user
Batch MAJOR prompts	Loses context	Prompt individually
Skip lock file	Irreproducible builds	Always commit lock files
Ignore security alerts	Vulnerabilities	Address by severity

---

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:

File Found	Language	Package Manager
package.json	Node.js	npm/yarn/pnpm
requirements.txt	Python	pip
pyproject.toml	Python	pip/poetry
Pipfile	Python	pipenv
go.mod	Go	go modules
Cargo.toml	Rust	cargo
Gemfile	Ruby	bundler
pom.xml	Java	Maven
build.gradle	Java/Kotlin	Gradle
*.csproj	.NET	dotnet

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:

Package	Reason
lucide-react	Icon library, majors are additive
@types/*	Type definitions, usually safe

</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

Specifier	Meaning	Example
^1.2.3	Minor + Patch OK	>=1.2.3 <2.0.0
~1.2.3	Patch only	>=1.2.3 <1.3.0
1.2.3	Exact (fixed)	Only 1.2.3
>=1.2.3	At least	Any >=1.2.3
*	Any	Latest (dangerous)

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
