compare
Compare multiple alternatives using explicit criteria, weighted scoring, and tradeoff analysis. Use when choosing between options, evaluating alternatives, or making decisions.
npx skills add majiayu000/claude-skill-registry --skill compare --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.
## Intent Systematically evaluate multiple alternatives against defined criteria to produce a recommendation with transparent tradeoff analysis. Comparison enables informed decision-making through structured analysis. **Success criteria:** - All options evaluated against same criteria - Criteria weighted by importance - Clear recommendation with rationale - Tradeoffs explicitly documented **Compatible schemas:** - `schemas/output_schema.yaml` ## Inputs | Parameter | Required | Type | Description | |-----------|----------|------|-------------| | `options` | Yes | array[string\|object] | Alternatives to compare (2+ items) | | `criteria` | Yes | array[string\|object] | Evaluation dimensions with optional weights | | `context` | No | object | Constraints, priorities, or decision context | | `must_have` | No | array[string] | Required criteria (eliminates options that fail) | ## Procedure 1) **Enumerate options**: List all alternatives under consideration - Verify each option is viable (not obviously invalid) - Ensure options are at same abstraction level - Flag if options are not mutually exclusive 2) **Define criteria**: Establish evaluation dimensions - Quantitative criteria: measura

How do I install it?

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.
