Migrate Skills Between Libraries

Goal

Move skills from one library workspace to another without losing metadata, breaking dependencies, or duplicating entries.

Guardrails

Always use --dry-run before any mutating command in the target workspace.
Always use --list to inspect the source library before importing.
Always use --format json for structured output when scripting migrations.
Never import skills without checking for name collisions in the target workspace first.
Always run build-docs in the target workspace after migration.

Workflow

Export: Identify skills to migrate from the source library

List all skills in the source workspace.

cd /path/to/source-library
npx ai-agent-skills list --format json --fields name,tier,workArea,collections

For house copies, note the skill folder paths. For upstream picks, note the installSource.

Import: Add skills to the target workspace

For house copies, use vendor to copy the skill folder into the target:

cd /path/to/target-library
npx ai-agent-skills vendor /path/to/source-library --skill <name> --area <workArea> --branch <branch> --why "Migrated from source library." --dry-run
npx ai-agent-skills vendor /path/to/source-library --skill <name> --area <workArea> --branch <branch> --why "Migrated from source library."

For upstream picks, use catalog to re-catalog from the original source:

npx ai-agent-skills catalog <owner>/<repo> --skill <name> --area <workArea> --branch <branch> --why "Migrated from source library." --dry-run
npx ai-agent-skills catalog <owner>/<repo> --skill <name> --area <workArea> --branch <branch> --why "Migrated from source library."

Rebuild docs in the target workspace.

npx ai-agent-skills build-docs

Validate the target workspace.

npx ai-agent-skills validate

Gotchas

Skill names must be unique per workspace. Check for collisions before importing.
House copies are full folder copies — the source and target are independent after migration.
Upstream picks re-catalog from the original upstream source, not the intermediate library.
Dependencies (requires field) must also be migrated. Check info --format json for each skill's dependency graph.
Collection membership does not transfer automatically. Use curate --collection <id> to add migrated skills to target collections.

Skill Creator

by anthropics

vendor ×10

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Replace with description of the skill and when Claude should use it.

Dispatching Parallel Agents

by ZhanlinCui

×5

Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies

This skill should be used when the user wants to "create a skill", "add a skill to plugin", "write a new skill", "improve skill description", "organize skill content", or needs guidance on skill structure, progressive disclosure, or skill development best practices for Claude Code plugins.

Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.

Use when creating new skills, editing existing skills, or verifying skills work before deployment

How to use it

Copy the folder

Take moizibnyousaf/migrate-skills-between-libraries from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npx. Without those the skill loads but fails at the first command.
