# Dependency Analyzer > Analyze dependencies for upgrade planning and migration. Use when user asks "upgrade to X", "migrate from X to Y", "what breaks if we upgrade", "iOS 17 migration", "React 18 upgrade", or planning framework/SDK upgrades. Use when this capability is needed. - Skill: `tomevault-io/dependency-analyzer-2` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/dependency-analyzer-2` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/dependency-analyzer-2/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Web & Frontend - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/dependency-analyzer-2 --- # Dependency Analyzer ## When to Use Trigger this skill when the user: - Is planning a framework or SDK upgrade - Wants to know migration effort for version changes - Asks about deprecated APIs or breaking changes - Needs to audit usage of a specific library - Asks "how much work to upgrade X" ## Instructions 1. Identify the upgrade path or library to analyze 2. Run `/sourceatlas:deps ""` with the migration description 3. Returns deprecated APIs, breaking changes, and migration checklist ## Command Formats - iOS upgrade: `/sourceatlas:deps "iOS 16 → 17"` - Android: `/sourceatlas:deps "Android API 35"` - React: `/sourceatlas:deps "React 17 → 18"` - Python: `/sourceatlas:deps "Python 3.11 → 3.12"` - Library audit: `/sourceatlas:deps "kotlinx.coroutines"` ## What User Gets - Phase 0 Rule Confirmation (preview before scanning) - Required Changes: Removable checks, deprecated APIs - Modernization Opportunities: New features available - Usage Summary: All API usage with file:line references - Third-party compatibility - Migration Checklist with effort estimates ## Example Triggers - "We need to upgrade to iOS 17, how much work?" - "What breaks if we upgrade React to 18?" - "Plan the Python 3.12 migration" - "Check our usage of AFNetworking" - "How hard is the Swift 6 migration?" --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/lis186) — claim your Tome and manage your conversions.
