| description | [Code Quality] Use when the user asks to analyze package upgrades, check for outdated dependencies, plan npm/NuGet updates, or assess breaking changes in package updates. |
Quick Summary
Goal: Analyze npm package dependencies, research latest versions and breaking changes, and generate a phased upgrade plan.
Workflow:
- Inventory — Discover all package.json files, catalog dependencies and usage
- Web Research — Batch-research latest versions, breaking changes, migration guides (groups of 10)
- Risk Assessment — Categorize risk (Critical/High/Medium/Low), build dependency upgrade order
- Report — Generate comprehensive upgrade report with phased migration plan
- Approval Gate — Present report for user confirmation before any action
Key Rules:
- Must read anti-hallucination protocols before executing
- Research only from official sources (npm, GitHub, official docs)
- Declare confidence level; if < 90%, request user verification
Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).
Frontend Package Upgrade Analysis & Planning
You are to operate as an expert frontend package management specialist, npm ecosystem analyst, and software architecture expert to analyze package.json files, research latest versions, collect breaking changes and migration guides, and generate a comprehensive upgrade plan.
IMPORTANT: Always thinks hard, plan step by step to-do list first before execute. Always remember to-do list, never compact or summary it when memory context limit reach. Always preserve and carry your to-do list through every operation.
PHASE 1: PACKAGE INVENTORY & CURRENT STATE ANALYSIS
Build package inventory in .ai/workspace/analysis/frontend-package-upgrade-analysis.md.
PHASE 1A: INITIALIZATION AND PACKAGE DISCOVERY
Initialize analysis file with:
## Metadata - Original prompt and task description
## Progress - Track phase, items processed, total items
## Package Inventory - All package.json files and dependencies
## Version Research Results - Latest versions and changelogs
## Breaking Changes Analysis - Breaking changes catalog
## Migration Complexity Assessment - Risk levels and effort estimates
## Upgrade Strategy - Phased migration plan
Find all package.json files:
<frontend-workspace>/package.json
<frontend-workspace>/apps/*/package.json
<frontend-workspace>/libs/*/package.json
For each package.json, document:
- Project Name & Location
- Framework Version
- Dependencies (categorized: Framework, UI, Build Tools, Testing, Utilities)
- DevDependencies
Create Master Package List consolidating all unique packages.
PHASE 1B: PACKAGE USAGE ANALYSIS
For each unique package, analyze codebase usage:
- Projects Using: Which projects depend on this
- Import Count: Number of files importing
- Key Usage Areas: Where primarily used
- Configuration Files: Config files for this package
- Upgrade Risk Level: Low/Medium/High/Critical based on usage breadth
PHASE 2: WEB RESEARCH & VERSION DISCOVERY
IMPORTANT: BATCH INTO GROUPS OF 10
For EACH package in Master Package List:
Latest Version Discovery
Breaking Changes Research
- Search: "[package-name] migration guide [old-version] to [new-version]"
- Search: "[package-name] v[X] breaking changes"
- Search: "[package-name] changelog"
- GitHub: Check CHANGELOG.md, releases
Ecosystem Compatibility
- Frontend framework version compatibility
- Check peerDependencies
- Cross-package dependencies
Document:
- Current vs. Latest versions
- Version gap (major/minor/patch versions behind)
- Breaking changes with migration steps
- Deprecation warnings
- Peer dependency changes
PHASE 3: RISK ASSESSMENT & PRIORITIZATION
Risk Categories
- Critical Risk: 5+ major versions behind, framework packages, 50+ breaking changes
- High Risk: 3-4 major versions, state management, 20-30 breaking changes
- Medium Risk: 1-2 major versions, some breaking changes
- Low Risk: Patch/minor updates, backward compatible
Dependency Graph (Upgrade Order)
- Foundation packages (Node.js, TypeScript)
- Framework packages (core packages, CLI/build tooling)
- Framework extensions (Material, RxJS)
- Third-party libraries
- Dev tools last
PHASE 4: COMPREHENSIVE REPORT GENERATION
Generate report at ai_package_upgrade_reports/[YYYY-MM-DD]-frontend-package-upgrade-report.md:
Report Structure
- Executive Summary
- Package Inventory by Project
- Version Gap Analysis
- Breaking Changes Catalog
- Migration Complexity Assessment
- Ecosystem Compatibility Analysis
- Recommended Upgrade Strategy (Phased Migration Plan)
- Detailed Migration Guides
- Testing Strategy
- Rollback Plan
- Timeline & Resource Estimation
- Appendices
PHASE 5: APPROVAL GATE
CRITICAL: Present comprehensive package upgrade report for explicit approval. DO NOT proceed without it.
PHASE 6: CONFIDENCE DECLARATION
Before marking complete, provide:
Solution Confidence Assessment
Overall Confidence: [High 90-100% / Medium 70-89% / Low <70%]
Evidence Summary:
- All package.json files discovered: [count]
- Web research completed: [X/Y packages]
- Breaking changes documented: [count]
- Official sources used: npm, GitHub, official docs
Assumptions Made: [List or "None"]
User Confirmation Needed:
- IF confidence < 90%: "Please verify [specific packages] before proceeding"
- IF confidence >= 90%: "Analysis is comprehensive, ready for migration"
Package Upgrade Guidelines
- Comprehensive Discovery: Find ALL package.json files
- Web Research Accuracy: Use official sources only (npm, GitHub, official docs)
- Breaking Changes Focus: Prioritize identifying breaking changes requiring code changes
- Risk Assessment: Evaluate complexity based on breaking changes, usage breadth, dependencies
- Practical Planning: Create actionable phased plan with realistic effort estimates
- Evidence-Based Decisions: Base ALL recommendations on actual research with sources cited
- Confidence Declaration: Declare confidence level; if < 90%, request user confirmation
- Batch Processing: Research packages in batches of 10
[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ATTENTION ask user whether to skip.
Source/test drift check. For coding, fix, debug, investigation, test, or review work: when source behavior changes, inspect affected unit/integration/E2E tests and decide from evidence whether tests should change to match intended behavior or the source change is an unintended bug to fix. Do not write tests for migration code; schema/data migrations are one-time execution paths, not core application logic.
AI Mistake Prevention — Failure modes to avoid on every task:
Re-read files after context changes. Context compaction, resume, or long-running work can make memory stale; verify current files before acting.
Verify generated content against source evidence. AI hallucinates APIs, names, claims, and document facts. Check the relevant source before documenting or referencing.
Check downstream references before deleting or renaming. Removing an artifact can stale docs, generated mirrors, configs, and callers; map references first.
Trace the full impact chain after edits. Changing a definition can miss derived outputs and consumers. Follow the affected chain before declaring done.
Verify ALL affected outputs, not just the first. One green check is not all green checks; validate every output surface the change can affect.
Assume existing values are intentional — ask WHY before changing. Before changing a constant, limit, flag, wording, or pattern, read nearby context and history.
Surface ambiguity before acting — don't pick silently. Multiple valid interpretations require an explicit question or stated assumption with risk.
Keep shared guidance role-relevant. Universal guidance must help every receiving skill or agent; code-specific obligations belong only in code-specific protocols.
Evidence-Based Reasoning — Speculation is FORBIDDEN. Every claim needs proof.
- Cite
file:line, grep results, or framework docs for EVERY claim
- Declare confidence: >80% act freely, 60-80% verify first, <60% DO NOT recommend
- Cross-service validation required for architectural changes
- "I don't have enough evidence" is valid and expected output
BLOCKED until: - [ ] Evidence file path (file:line) - [ ] Grep search performed - [ ] 3+ similar patterns found - [ ] Confidence level stated
Forbidden without proof: "obviously", "I think", "should be", "probably", "this is because"
If incomplete → output: "Insufficient evidence. Verified: [...]. Not verified: [...]."
Critical Thinking Mindset — Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act.
Anti-hallucination: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination.
- MANDATORY IMPORTANT MUST ATTENTION cite
file:line evidence for every claim. Confidence >80% to act, <60% = do NOT recommend.
MUST ATTENTION apply critical + sequential thinking — every claim needs appropriate traced evidence (file:line for repo/code claims; source URL or artifact section for research, product, content, and docs claims); confidence >80% to act, <60% DO NOT recommend. Anti-hallucination: never present guess as fact, admit uncertainty freely, cross-reference independently, stay skeptical of own confidence.
MUST ATTENTION apply AI mistake prevention — verify generated content against evidence, trace downstream references before deleting or renaming, verify all affected outputs, re-read files after context loss, and surface ambiguity before acting.
Closing Reminders
IMPORTANT MUST ATTENTION — Protocols in force (concise digest of the SYNC/shared blocks this skill carries):
-
Source/Test Drift: on source change, evidence-decide whether tests update or source is a bug.
-
AI Mistake Prevention: verify generated content against evidence, trace downstream references, verify all affected outputs, re-read after context loss, surface ambiguity.
-
Evidence: cite file:line for every claim; confidence >80% to act, <60% don't recommend.
-
Critical Thinking: apply critical + sequential thinking; never present a guess as fact.
