compare-architectures
Generate and compare multiple architecture options (minimal, moderate, full modernization) with comprehensive trade-offs analysis across cost, timeline, risk, performance, and maintainability dimensions. Use when evaluating multiple architectural approaches or deciding between modernization strategies with different cost/risk trade-offs.
npx skills add majiayu000/claude-skill-registry --skill compare-architectures-adolfoaranaes12-bmad-enhanced-2 --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.
What it does
Generates three architecture options (minimal, moderate, full) and analyzes trade-offs across cost, timeline, risk, performance, and maintainability; provides a clear recommendation with justification and a next-steps plan. It enforces a side-by-side comparison matrix and outlines an implementation roadmap for the recommended option.
How it works
The skill analyzes current state and new requirements, then generates three distinct options with concrete characteristics (technology stack, architecture, changes required). For each option, it estimates development effort, infrastructure impact, migration needs, and training considerations. It then performs a trade-offs analysis across cost, timeline, risk, performance, and maintainability, presenting a comparison matrix for easy evaluation. Finally, it generates a recommendation with justification and defines next steps/roadmap for the selected option. Outputs include: a comparison document location, number of options (always 3), the recommended option, and a confidence score.
When to use it
Use when evaluating multiple architectural approaches or deciding between modernization strategies with different cost/risk trade-offs.
What it can touch
The skill references tools and outputs related to architecture analysis and generation, including a comparison document and a recommendation; the exact touchpoints are defined in inputs/outputs and telemetry sections.
Caveats
The skill requires a workspace/directory for output storage and expects clear new requirements and constraints. It generates three options with cost, timeline, and risk estimates, but real-world results depend on project context and data inputs. The outputs include a recommendation based on the provided constraints and assumptions outlined in the workflow.
# Compare Architectures Skill ## Purpose Generate three distinct architecture options with comprehensive trade-offs analysis to help users make informed decisions about system modernization or design. Each option represents a different investment level (minimal, moderate, full) with detailed cost, timeline, risk, and quality analysis. **Core Principles:** - Present 3 viable options (not 1 perfect solution) - Honest trade-offs analysis (no "best" option without context) - Evidence-based estimates (cost, timeline, risk) - Clear recommendation with justification - Actionable next steps for chosen option ## Prerequisites - Understanding of current system (if brownfield) - Clear new requirements or goals - User constraints known (timeline, budget, team) - workspace/ directory exists for output storage --- ## Workflow ### Step 1: Analyze Current State & Requirements **Action:** Understand current architecture and new requirements to create meaningful options. **Key Activities:** 1. **Load Current Architecture (if brownfield)** ```bash # If current_architecture path provided python .claude/skills/bmad-commands/scripts/read_file.py \ --path {current_architecture} \ --output json # Extract:

What does the compare-architectures skill do?
Generate and compare multiple architecture options (minimal, moderate, full modernization) with comprehensive trade-offs analysis across cost, timeline, risk, performance, and maintainability dimensions. Use when evaluating multiple architectural approaches or deciding between modernization strategies with different cost/risk trade-offs.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill compare-architectures-adolfoaranaes12-bmad-enhanced-2 --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.
