app-analyzer-optimizer

app-analyzer-optimizer is a skill for Cursor from roedyrustam/vibes-plug. It costs 56 tokens per session (2,231 once invoked), scanned A, original, MIT.

An application review guide that examines project structure, architecture, code quality, bundles, and database queries. It covers Next.js, React, Node.js, Go, Python, and Rust applications.

In plain words
What is it for?
Use it to audit an existing codebase, find slow API routes or database queries, inspect bundle size, identify code-splitting opportunities, and review complexity, duplication, or dead code.
Why use it?
It helps locate architectural problems and performance slowdowns that are difficult to spot by reading files one at a time. It also helps identify large bundles, repeated database queries, duplicated code, and unused code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

app-analyzer-optimizer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Orchestration & Integration

  • Upstream & Lifecycle: zero-to-prod-orchestrator (Phase 5 Optimization & Phase 6 QA), brainstorming, session-memory-manager.
  • AST & Codebase Graph: living-codebase-ast-graph (circular dependency & module size analysis), scalability-clean-code (code smell & God class refactoring).
  • Performance & Vitals: performance-web-vitals (Core Web Vitals LCP/INP profiling), production-ready-hardener (bundle audits & pre-flight hardening).
  • Database & Backend Profiling: database-orm-expert (N+1 query & index profiling), coderabbit (automated AI code review).

Description

Deep application analysis and optimization skill. Performs architectural audits, bottleneck detection, bundle analysis, database query profiling, and AI-assisted code review across Next.js, React, Node.js, Go, Python, and Rust applications.

Trigger Conditions

  • Auditing an existing codebase for architectural issues or technical debt.
  • Detecting performance bottlenecks (slow API routes, large bundles, N+1 queries).
  • Analyzing bundle size and suggesting code splitting opportunities.
  • Reviewing code quality (complexity, duplication, dead code).
  • Using AI-assisted tools to accelerate code review and analysis.

Analysis Protocol (5 Phases)

Phase 1: Architecture Discovery
# Map the entire project structure
find . -type f -name "*.ts" -o -name "*.tsx" -o -name "*.go" | head -100
# Count lines per file (find largest files)
find . -name "*.ts" -exec wc -l {} + | sort -rn | head -20
# Find circular dependencies (TypeScript/JS)
npx madge --circular --extensions ts,tsx src/
Phase 2: Bundle Analysis (Next.js / Vite)
# Next.js bundle analyzer
ANALYZE=true next build

# Or install dedicated tool
npx @next/bundle-analyzer

# Vite bundle visualization
npx vite-bundle-visualizer

# Check for duplicate dependencies
npx depcheck
npx bundle-phobia-cli check package.json
