THE AGENT HARNESS INDEX

Pick your
agent’s home.

Agent harnesses are the environments that give a model context, tools, memory, permissions, and a way to get work done. Here are the popular options—from Cursor to OpenClaw and Hermes—with the official place to start each one.

Start in a project folderGive the agent a bounded workspace, not your entire machine.
Review before broad accessConnect keys, browsers, or messaging only when the task calls for it.
Use Git checkpointsCommit or stash before an agent makes a meaningful change.
SKILLY.SH IN ANY HARNESS

Find a skill. Add it in your project.

Skilly helps you find the capability; your harness uses it inside the repository you have open. Review the publisher’s instructions before installing.

  1. 01

    Browse Skilly, open a skill, and read its original instructions and source.

  2. 02

    Copy the install command, then run it from this harness’s project terminal: npx skilly-cli add owner/repo --skill name.

  3. 03

    Select your harness in the installer when it is offered, then reopen the project or start a fresh agent task so it reads the new skill.
