npx skills add majiayu000/claude-skill-registry --skill classify --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 Assign one or more labels from a defined taxonomy to items based on their observed characteristics. This capability bridges detection and reasoning by providing semantic categorization. **Success criteria:** - Item assigned at least one label from taxonomy - Label assignment supported by evidence - Confidence scores reflect classification certainty - Ambiguous cases explicitly flagged **Compatible schemas:** - `schemas/output_schema.yaml` ## Inputs | Parameter | Required | Type | Description | |-----------|----------|------|-------------| | `item` | Yes | any | The item to classify (entity, document, code, data) | | `taxonomy` | No | string\|array | Classification scheme or list of valid labels | | `multi_label` | No | boolean | Whether multiple labels can be assigned (default: false) | | `context` | No | object | Additional context to inform classification | ## Procedure 1) **Examine the item**: Gather characteristics relevant to classification - Identify distinguishing features - Note structural patterns, content type, metadata - Collect evidence for each observed characteristic 2) **Understand the taxonomy**: Clarify the classification scheme - If taxonomy provided, us

What does the classify skill do?
Assign labels or categories to items based on characteristics. Use when categorizing entities, tagging content, identifying types, or labeling data according to a taxonomy.
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.
