Blocks CI Sessions — Development skill for Claude Code

Blocks Agent Sessions

[](https://github.com/BlocksOrg/blocks-ci-sessions/actions/workflows/ci.yml) [](https://github.com/BlocksOrg/blocks-ci-sessions/releases/latest) [](https://github.com/marketplace/actions/blocks-agent-sessions) [](./LICENSE)

Run cloud coding agent sessions from your CI workflows. A single step starts a [Blocks](https://blocks.team) agent session, waits for the agent's final message, and exposes the session id so later jobs can chain off it.

• Your favourite agent. Claude Code, Codex, Kimi Code, OpenCode, Cursor or Gemini.
• Your credentials, or ours. Bring your own subscriptions and API keys, or use Blocks inference.
• Your choice of model. Frontier models such as Fable and Astra, or open-source models like Kimi 3.0 and GLM 5.3, including inside Claude Code.
