Read excerpt


A skill is a packaged capability: a directory with a `SKILL.md` (purpose + instructions the agent reads), optional reference docs, scripts, samples. Hand it to the agent and it will use it when relevant.

Harness lets you install skills from two places:

- **Skill marketplaces** — Git repo, Nacos, MySQL, classpath, custom stores
- **Workspace** — `workspace/skills/` is shared by everyone; `<userId>/skills/` isolates per user

Both sources are active simultaneously — no need to choose one. On top of that you can enable a **self-learning loop**: the agent drafts skills → review gate → background curator tidies up.

A skill directory looks like:

```
code-reviewer/
├── SKILL.md           # required — YAML frontmatter (name + description) + instructions for the agent
