Centaur is a runtime & deploy option for building AI agents. Paradigm's self-hosted control plane: one shared team agent, an isolated k8s sandbox per Slack thread, and no raw API keys in the agent's environment.
Worth knowing. Brings your own harness — it runs Claude Code, Codex or Amp inside the sandbox rather than replacing them. Credential boundaries mean the agent calls approved services without ever holding the key.
