Skills are packaged instruction bundles that teach Claude Code how to carry out a specific task. Each one is a SKILL.md file with a short name and description, optionally bundled with helper scripts, templates, and reference documents. Unlike a slash command you trigger by hand, a skill is model-invoked: Claude reads the one-line description of every installed skill and pulls the full instructions into context only when your request matches. That progressive-disclosure design keeps your context window lean while still giving Claude a deep, reusable playbook the moment it is needed.

Reach for a skill whenever you have a repeatable workflow that should always be done the same way — rendering a chart to a house style, writing a changelog from commits, scaffolding a component, generating a PDF, or running a domain-specific review. Because skills live in .claude/skills/ and travel with your repository, every teammate and every session inherits the same capability without anyone remembering to invoke it. Install any skill from this catalog with a single command:

npx claude-code-templates@latest --skill="category/name" --yes

Browse the full collection below, or explore related component types: slash commands you trigger explicitly, subagents that run in their own isolated context, and hooks that fire automatically on lifecycle events. Popular skills in this catalog include changelog-writer, pdf-generator, and test-scaffolder.

Frequently Asked Questions

What is a Claude Code skill?
A skill is a packaged bundle of instructions that gives Claude Code a reusable capability. At minimum it is a SKILL.md file containing a name, a description, and step-by-step guidance; it can also ship with helper scripts, templates, and reference files. Skills are stored in the .claude/skills/ directory of your project (or your user config) and are loaded on demand rather than run manually.
What does "model-invoked" mean, and how does Claude decide to use a skill?
Model-invoked means Claude chooses when to apply a skill instead of you triggering it explicitly. At the start of a session Claude only sees each skill's short name and description. When your request matches one, Claude loads that skill's full instructions into context and follows them. This progressive disclosure keeps the context window small while still making detailed, task-specific guidance available the instant it is relevant.
How are skills different from slash commands and subagents?
A slash command is invoked explicitly by typing its name and runs a fixed prompt in your current session. A subagent runs in its own isolated context so a large task does not clutter the main conversation. A skill sits in between: it is a reusable instruction bundle that Claude pulls in automatically when a task matches, without a manual trigger and without spawning a separate agent. Many teams use all three together — see the commands and agents hubs for those types.
How do I install a Claude Code skill from ToolZip?
Copy the install command shown on any skill's page and run it in your project. The general form is: npx claude-code-templates@latest --skill="category/name" --yes. This writes the skill into your .claude/skills/ directory. Once it is there, Claude Code discovers it automatically on the next session and can invoke it whenever a matching task comes up — no additional configuration required.
Are these skills free, and where do they come from?
Yes. Every skill in the catalog is free to install and use. The underlying components are sourced from the open-source davila7/claude-code-templates project, which is MIT licensed. ToolZip curates, categorizes, and re-documents them with original write-ups so you can search and compare skills quickly, then install the exact one you need with a single command.

Catalog data and component content are sourced from the open-source davila7/claude-code-templates project (MIT license).
