What it is, in our words
A coding agent we run as the interchangeable home base: a CLI, MCP on both sides, and a harness an agent can drive.
What we measured
Same shape as Codex: a CLI, MCP on both sides, and an agent SDK that exposes the whole harness. It collapses the number of interfaces you operate in.
Our published skill guides assume you can run a coding agent against a repo and give it checked rules, which is the part that makes the skills compound.
Surface we measured: official MCP server, CLI available, full REST, tier S.
Vendor
Claude Code. We link out and make no claim about their current pricing, terms or roadmap.
