Agent work that passes the demo breaks on Tuesday's merge — the test fails, the lint errors accumulate, and nobody can reconstruct what the agent actually did or why it thought the job was done. Orbit is the harness built to close that gap.

Summary
Orbit wraps each coding agent run in a bounded loop: one task, validation gates (tests, lint, type checks), and a fixed set of JSON artifacts recording exactly what the agent returned, what the checks proved, and what should happen next. It is agent-neutral — Claude, Codex, Cursor, or any CLI that speaks JSON fits behind the same contract. The dependency-aware backlog means tasks run in order and only advance when the previous orbit closes cleanly. Where it stops: Orbit has no API and no dashboard, so teams that need live metrics or cross-run analytics build those themselves on top of the artifact files.
Bottom line: Orbit earns its place in a CI/CD pipeline where you need auditable proof that an agent's output passed real checks before merge — but if your team needs a hosted control plane or web-based run history, you are building that infrastructure yourself.

Pros
- Validation gates run tests, lint, and type checks before an orbit closes, so broken agent output cannot silently advance into the backlog the way it does when agents self-report completion.
- Four structured artifact files per run (agent result, evaluation, review recommendation, progress log), which means you have auditable evidence of what the agent did without building a logging layer yourself.
- Agent-neutral JSON contract lets you swap Claude, Codex, or Cursor behind the same harness, so comparing agent performance on identical tasks produces artifact-level evidence instead of anecdote.
- Dependency-aware backlog selection runs tasks in verified order, so a downstream task cannot start before the orbit it depends on has closed with passing validation.
- MIT licensed and self-hostable with no commercial variant, so there is no paywalled feature ceiling to hit as your agent workflow grows.
Cons
- Orbit has no API and no dashboard — cross-run analytics, trend tracking, and live monitoring require teams to build their own tooling on top of the artifact files, which is a non-trivial infrastructure commitment once the number of orbits scales.
- Sequential, single-agent orbits are the design boundary: teams that need parallel agent execution, multi-agent handoffs, or branching logic based on intermediate results hit the edge of what the harness supports and typically move to a full orchestration framework (LangGraph, Prefect, or similar) at that point.
- The adapter ecosystem depends on community contributions — if your agent does not already have a supported JSON adapter, you write it yourself or wait, which is a real delay for teams evaluating proprietary or niche coding agents.

Curated lists that include this category
Most teams using coding agents eventually hit the same wall: the agent claims it’s done, the diff lands, and three hours later a test that was never run catches the breakage. Orbit is an open-source CLI harness (MIT licensed, vendor page confirmed) that wraps agent execution in what it calls an orbit — one task selected from a dependency-ordered backlog, handed to a coding agent, and gated on real validation before the orbit is marked closed. Every run produces four artifact files: a structured agent result, a rubric evaluation, a review recommendation, and a human-readable progress log. If the agent cannot prove completion through tests, lint, and type checks, the orbit does not advance.
The differentiating feature is agent-neutrality enforced through contract. Orbit does not care which coding agent sits behind it — the docs describe Claude, Codex, and Cursor as interchangeable as long as they speak the expected JSON shape. This means you can run the same task through different agents and compare the artifacts directly, replacing gut-feel conversations about which agent performs better with structured, identical-condition evidence.
Orbit fits tightly scoped CI workflows: self-healing repositories where failing tests must be resolved before work advances, backlog-driven projects that need dependency ordering, and compliance contexts where auditable agent traces are required before merge. It starts to strain when the workflow requires branching logic across agents, parallel execution, or any orchestration beyond sequential, single-agent orbits. The vendor page describes Orbit as intentionally small — contributions are expected to extend adapter coverage and mission templates, not to grow the core into a platform.
The deterministic replay demo (vendor page confirmed) runs without an API key using a MOCK flag, which means teams can validate the harness behavior locally before wiring in a live agent. There is no API surface and no self-hosted dashboard — artifact review happens by reading the JSON and Markdown files the harness writes to disk.
