91 Anthropic GitHub repos showcase Claude Code push

Anthropic’s GitHub org now lists 91 public repositories centered on Claude Code, SDKs, plugins, and agent tooling.

Anthropic’s GitHub organization shows 91 public repositories as of June 21, 2026, with most recent activity clustered around Claude Code, the agent SDKs, and plugin directories. The page points to a broad open-source push for developers building with Anthropic models, with several repos updated within the last two days.

What changed

The repo list is dominated by developer tools rather than model weights or research artifacts. Top entries include claude-code, skills, claude-plugins-official, and multiple SDKs for Python, TypeScript, Go, Java, C#, Ruby, PHP, and Kotlin.

The org also surfaces newer workflow-specific projects, including claude-code-action for GitHub automation, claude-agent-sdk-python and its TypeScript counterpart for agent integration, plus claude-cookbooks for usage examples. Several repos show active maintenance in mid-June 2026.

• claude-code: terminal-based agentic coding tool, 134k stars
• skills: agent skills repo, 154k stars
• claude-plugins-official: official plugin directory, 31k stars
• claude-agent-sdk-python: SDK for agent workflows in Python

Why it matters

For developers, the repo mix signals where Anthropic wants adoption to happen: inside the terminal, in CI, and through plugin-based workflows. That means fewer one-off demos and more building blocks for teams wiring Claude into existing software delivery pipelines.

For the market, the org page is a public map of Anthropic’s product strategy. The emphasis on SDKs, plugins, and action-based automation suggests the company is competing not just on model quality, but on how easily teams can ship agentic features into real apps.

The main question now is not whether Anthropic has open-source surface area, but which of these repos becomes the default path for production agent builds.
