description: Orbit — the task/audit/dispatch layer for AI coding agents. Use for anything touching a task ID, `.orbit/`, `orbit` CLI or `orbit.*` MCP tools, the docs corpus, friction records, jobs and `jrun-*` runs, routines, auto-tasks, the sweep clock, worktree GC, task publication and recovery, federated MCP, the dashboard, or setting Orbit up on a machine or repository. Covers both doing work through Orbit and configuring Orbit so that work runs unattended.

# Orbit

Orbit governs AI coding agents: every change is a task, every task carries an
audit trail, and work dispatches into sandboxed parallel runs. Durable
operations go through the registered tool surface — never direct lifecycle
subcommands, never a rebuild from source.

This file is the router. It carries only what every Orbit call needs; each
reference below is loaded on demand.

## Tool Invocation

Use the connected, authoritative MCP server for durable work. First call
`orbit_workspace_list`, select the intended workspace, and copy its selector
into workspace-scoped calls. A direct server returns `ws_*` IDs; a federated
server returns host-qualified `selector` values. Never infer authority from
cwd or silently substitute a different machine's local store.

Registered CLI tools use `orbit tool run orbit.task.add --input '{...}'`;
MCP uses `orbit_task_add({...})`. Dots become underscores, but **CLI tool
registration does not imply MCP exposure**. Discover the connected server's
`tools/list` before calling. Use CLI administration on the intended host only
when the operation and authority are available and authorized.

Include `model` (`codex`, `claude`, `gemini`, or `grok`) on calls whose schema
supports attribution. This is the agent family, not the crew or model ID.
Follow each advertised schema for other fields; examples in these references
use placeholders that must be replaced, not sent literally.

Read [tool-surface.md](references/tool-surface.md) for the actual capability
split, routing, structured examples, and missing-operation handling. Filesystem
inspection and CLI-only diagnostics in these references refer to the host that
owns the selected workspace. They do not authorize local shadow records.

A plain `orbit_task_show` returns full detail; `field`/`fields` project it.
If an activity already injected a task snapshot, use that envelope first.

## Lifecycle

```text
proposed → backlog → in-progress → review → done
         ↘ rejected

someday → in-progress
blocked → in-progress

review      → rejected
rejected    → backlog | in-progress  (reconsider)
```

Creating a task does not authorize dispatch or completion. Follow the user's
approval and repository delivery policy. The diagram summarizes common paths;
`task.start` also supports authorized pickup from `proposed` with a real plan.
Use `blocked` when execution cannot safely continue. Provenance follows the
surface: `orbit tool run ...` is agent-driven, bare `orbit task ...` is
human-driven.

## Common Mistakes — DO NOT

| Mistake | Why it fails | Correct form |
|---------|-------------|--------------|
| `cargo run -- tool run ...` | Rebuilds from source instead of using the installed binary | `orbit tool run ...` |
| `orbit task show <id>` | Direct CLI subcommands skip agent provenance tracking | `orbit tool run orbit.task.show --input '{"id":"<id>"}'` |
| Editing task/friction projections or runtime evidence under `.orbit/` | File edits bypass the canonical store and audit contract | The matching registered tool; versioned config/resources are a separate admin surface |
| Inventing a task ID | IDs are allocated by the store | `orbit.task.add` returns it |

**Setting Orbit up** — configuring a machine or repository so work runs well.
Use these references to configure the host and workspace. Scheduled automation
is seeded disabled and requires deliberate enablement:
