A practical checklist for choosing Claude Code extensions

Claude Code's extension ecosystem is growing quickly, but a long list of options does not tell you which one belongs in your workflow. The useful first question is: what specific task am I trying to improve?

Match the extension to the job

Different extension types solve different problems:

• Skills package reusable instructions or workflows. Start here when the main problem is making a repeatable task easier to invoke.
• Hooks run actions around events. They suit deterministic checks or automation, but deserve a careful review because they can execute commands.
• MCP servers connect Claude Code to external tools or data. Use one when the workflow actually needs that integration, and check what access it requests.
• Agents and subagents help divide a larger task into focused roles. Define the scope of each role before adding more moving parts.
• Plugins can bundle capabilities for distribution. Check what is inside the bundle rather than assuming every included component is needed.

For example, if you need a consistent review checklist, try a skill before adding a service integration. If you need to query an external system, a skill alone will not provide that connection.

Inspect before installing

A short review can prevent most avoidable surprises:

1. Follow the link to the original source and read the setup instructions.
2. Identify the commands, files, network calls, and credentials the extension needs.
3. Check whether the project is maintained and whether its behavior is clear from the documentation.
4. Note how to disable or remove it if the trial does not help.

Avoid giving an extension production credentials merely to see what it does. For hooks and integrations in particular, inspect the actual behavior before enabling them in a daily workflow.

Trial one change at a time

Try the candidate in a small project with a concrete task. Compare the output and effort with your existing workflow, and keep a note of any extra permissions or maintenance it introduces. Adding several extensions at once makes it hard to tell which one helped.

I built Code Mods Hub as a bilingual directory for browsing Claude Code mods, skills, plugins, hooks, MCP servers, and related projects. Listings point back to original sources, so the directory can help you shortlist candidates while the source remains the place to verify setup and behavior.

The goal is not to install the largest collection. It is to find the smallest set that improves a task you actually perform.
