Learning Skills

Overview

This skill runs in a forked context and helps you discover and install relevant skills for a given task using a two-tier approach:

1. Local repositories (preferred): Search through known, validated repositories in @./SKILL_REPOSITORIES.md
2. Remote search (fallback): Query the skills.sh API to discover skills from the broader ecosystem

Context: When invoked, use $ARGUMENTS to understand what skills are needed. For example, if invoked as /kung-fu Flask API with authentication, search for Flask and authentication-related skills.

First, run the add-skill CLI with the help flag to get a general understanding of what it does and how it works:

npx -y add-skill --help

Source Formats

The CLI accepts multiple repository formats:

CLI Flags Reference

Reading

Read from the list of repositories in @./SKILL_REPOSITORIES.md and run each one:

npx -y add-skill <repository> --list

This displays a list of skill names and their associated descriptions.

Example

> npx -y add-skill vercel-labs/agent-skills --list

Do this for all known skill repositories.

Remote Search (skills.sh)

If no relevant skills are found in the known repositories, or if the user explicitly requests a remote search, use the skills.sh API to discover skills from the broader ecosystem.

When to use remote search:

• User explicitly asks to “search for skills” or “find skills remotely”
• No relevant skills found in @./SKILL_REPOSITORIES.md for the task at hand
• Working with an unfamiliar technology or domain

Important: Before searching remotely, ask the user for confirmation unless they explicitly requested it.

Search API

curl -s "https://skills.sh/api/search?q=<query>&limit=<limit>"

Example Search

curl -s "https://skills.sh/api/search?q=flask&limit=10"

Response:

{
  "query": "flask",
  "searchType": "fuzzy",
  "skills": [
    {
      "id": "flask",
      "name": "flask",
      "installs": 70,
      "topSource": "jezweb/claude-skills"
    },
    {
      "id": "flask-api-development",
      "name": "flask-api-development",
      "installs": 11,
      "topSource": "aj-geddes/useful-ai-prompts"
    }
  ],
  "count": 2,
  "duration_ms": 2
}

Remote Search Workflow

1. Search for skills matching your task:

   curl -s "https://skills.sh/api/search?q=<technology>&limit=20"
   

2. Extract repositories from the topSource field in each result.

3. List descriptions from discovered repositories:

   npx -y add-skill <topSource> --list
   

4. Evaluate the skill descriptions to determine relevance.

5. Install relevant skills using the standard installation command.

Example: Finding Flask Skills

# Step 1: Search for flask skills
curl -s "https://skills.sh/api/search?q=flask&limit=10"

# Step 2: List skills from discovered repositories
npx -y add-skill jezweb/claude-skills --list
npx -y add-skill aj-geddes/useful-ai-prompts --list

# Step 3: Install the relevant skill
npx -y add-skill jezweb/claude-skills -y -a claude-code --skill flask

Deciding

Now that you see all available skills, install any skills that are related to the task at hand:

npx -y add-skill <repository> -y -a <agent-name> --skill <skill-name>

The agent name is the name of the agent you are using. See @./AGENTS.md for acceptable values.

Example

If your thoughts are along the lines of “I’m creating a website,” you should identify web-design-guidelines as a good skill to learn:

npx -y add-skill vercel-labs/agent-skills -y -a claude-code --skill web-design-guidelines

You can install multiple skills by repeating the --skill flag:

npx -y add-skill <repository> -y -a <agent-name> --skill <skill-a> --skill <skill-b> --skill <skill-c>

You may also install all skills from a repository at once:

npx -y add-skill <repository> -y -a <agent-name> --all

For global installation (user directory instead of project-level), add the -g flag:

npx -y add-skill <repository> -y -g -a <agent-name> --skill <skill-name>

Acknowledgment

After successfully installing skills, announce what you’ve learned using proper grammar:

One skill:

I know Terraform.

Two skills:

I know Terraform and Flask.

Three or more skills:

I know Terraform, Flask, and React.

This confirms to the user that the knowledge upload is complete.

Telemetry

To disable anonymous usage data collection:

DISABLE_TELEMETRY=1 npx -y add-skill <repository> --list

Telemetry is automatically disabled in CI environments.
