cwicr-comparison-tool
Compare cost estimates across projects, versions, and scenarios. Identify variances, benchmark against standards, and generate comparison reports.
npx skills add majiayu000/claude-skill-registry --skill cwicr-comparison-tool --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# CWICR Comparison Tool ## Business Case ### Problem Statement Project stakeholders need to compare: - Alternative design options - Estimate versions over time - Projects against benchmarks - Actual vs estimated costs ### Solution Structured comparison of CWICR-based estimates with variance analysis, benchmarking, and visual reporting. ### Business Value - **Decision support** - Compare alternatives objectively - **Version control** - Track estimate evolution - **Benchmarking** - Compare against standards - **Audit** - Document estimate changes ## Technical Implementation ```python import pandas as pd import numpy as np from typing import Dict, Any, List, Optional, Tuple from dataclasses import dataclass, field from datetime import datetime from enum import Enum class ComparisonType(Enum): """Types of comparisons.""" VERSION = "version" # Same project, different versions ALTERNATIVE = "alternative" # Same project, design alternatives BENCHMARK = "benchmark" # Project vs standard/benchmark ACTUAL = "actual" # Estimate vs actual costs PROJECT = "project" # Different projects class VarianceSignificance(Enum): """Significance level of variance.""" CRITICAL = "critical" # >20% variance

What does the cwicr-comparison-tool skill do?
Compare cost estimates across projects, versions, and scenarios. Identify variances, benchmark against standards, and generate comparison reports.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill cwicr-comparison-tool --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
