Reference
Glossary
Every Harbor term, defined once.
Harbor has a user-facing vocabulary (used on tryharbor.ai, in this docs body, in the dashboard) and a code vocabulary (used in the SDK, the API, and source files). Both are valid; this table is the canonical mapping.
Concept names
| User-facing (use in docs body) | Code-name (mention in SDK/API only) |
|---|---|
| Plugin | Source |
| Tool | Tool (same word) |
| Skill | Skill (same word) |
| Function | Orbit Job · defineJob · /orbit/jobs/* |
| App | Orbit App · deployApp · /orbit/apps/* |
| Exec | hrbr exec → /plugins/execute |
| Run | Run (same word) |
| Trace | Run + run spans |
| Workspace | Workspace |
| Local MCP bridge | Cliff (renamed from Reef in May 2026) |
| CLI | Coast binary, published as @zonko-ai/harbor, binary hrbr |
| Hosted MCP server | Lighthouse |
Not in user vocabulary
These words exist in code or implementation detail but do not appear as user-facing concepts.
| Internal term | Where it actually lives |
|---|---|
| Workflows | An execution lane inside a Function or Exec when code uses step.* — surfaces as Cloudflare Workflows. Not a top-level dashboard concept. |
| Triggers | Doesn't exist. Functions are scheduled; Workflows wait for events; Plugins emit webhooks. Each surface keeps its native word. |
| Sand | The local-CLI bridge primitive. Only mentioned on the Connecting and Sand authoring pages. |
| Orbit | The umbrella for workspace primitives (orbit.storage, orbit.cache, ...). User-facing as "Orbit Runtime", but most surfaces talk about the primitive (e.g. "storage", "AI") rather than the umbrella. |
_hidden | Frontmatter flag in this docs repo. Hides a routable page from the sidebar. Used by auto-generated plugin catalog pages. |
Component names
| Name | What it is |

| Orbit | The runtime primitives layer (/sdk/orbit). |
