tech-stack-evaluator

tech-stack-evaluator is a skill for Claude Code, Codex from alirezarezvani/claude-code-skill-factory. It costs 27 tokens per session (3,276 once invoked), scanned A, original, MIT.

A framework for comparing technologies, cloud providers, and complete technology stacks. It examines cost, security, ecosystem health, long-term viability, and migration needs.

In plain words
What is it for?
Use it to compare frameworks or databases, evaluate a full stack, estimate total cost of ownership, assess security and compliance, and plan migrations.
Why use it?
It helps engineering teams make technology choices using consistent criteria instead of comparing tools only by familiarity or headline features.

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

tech-stack-evaluator 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 4d ago.

The scan reads SKILL.md. This mod also ships 7 executable files (ecosystem_analyzer.py, format_detector.py, migration_analyzer.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Technology Stack Evaluator

A comprehensive evaluation framework for comparing technologies, frameworks, cloud providers, and complete technology stacks. Provides data-driven recommendations with TCO analysis, security assessment, ecosystem health scoring, and migration path analysis.

Capabilities

This skill provides eight comprehensive evaluation capabilities:

  • Technology Comparison: Head-to-head comparisons of frameworks, languages, and tools (React vs Vue, PostgreSQL vs MongoDB, Node.js vs Python)
  • Stack Evaluation: Assess complete technology stacks for specific use cases (real-time collaboration, API-heavy SaaS, data-intensive platforms)
  • Maturity & Ecosystem Analysis: Evaluate community health, maintenance status, long-term viability, and ecosystem strength
  • Total Cost of Ownership (TCO): Calculate comprehensive costs including licensing, hosting, developer productivity, and scaling
  • Security & Compliance: Analyze vulnerabilities, compliance readiness (GDPR, SOC2, HIPAA), and security posture
  • Migration Path Analysis: Assess migration complexity, risks, timelines, and strategies from legacy to modern stacks
  • Cloud Provider Comparison: Compare AWS vs Azure vs GCP for specific workloads with cost and feature analysis
  • Decision Reports: Generate comprehensive decision matrices with pros/cons, confidence scores, and actionable recommendations

Input Requirements

Flexible Input Formats (Automatic Detection)

The skill automatically detects and processes multiple input formats:

Text/Conversational:

"Compare React vs Vue for building a SaaS dashboard"
"Evaluate technology stack for real-time collaboration platform"
"Should we migrate from MongoDB to PostgreSQL?"

Structured (YAML):

comparison:
  technologies:
    - name: "React"
    - name: "Vue"
  use_case: "SaaS dashboard"
  priorities:
    - "Developer productivity"
    - "Ecosystem maturity"
    - "Performance"

Structured (JSON):

{
  "comparison": {
    "technologies": ["React", "Vue"],
    "use_case": "SaaS dashboard",
    "priorities": ["Developer productivity", "Ecosystem maturity"]
  }
}

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
