+# claude plugin
+
+[Claude Code](https://code.claude.com/docs) (Anthropic's agentic coding CLI)
+plugin for [proto](https://github.com/moonrepo/proto).
+
+## Installation
+
+claude is not built into proto, so register this plugin, pin a version, then
+install:
+
+```shell
+proto plugin add claude "https://raw.githubusercontent.com/Genesis-Embodied-AI/proto-plugins/main/claude/plugin.toml"
+proto pin claude <version> --resolve
+proto install claude
+```
+
+## Picking a version
+
+Versions track Claude Code's GitHub release tags
+(<https://github.com/anthropics/claude-code/releases>). The current release is
+also published at
+<https://downloads.claude.ai/claude-code-releases/latest>.
+
+## Notes
+
+- Binaries are served from `https://downloads.claude.ai/claude-code-releases/`
+  as a single executable per platform (no archive). Linux uses the static
+  `musl` build so it runs on both glibc and musl hosts.
+- Upstream publishes checksums only inside a per-version `manifest.json`, which
+  the TOML plugin format cannot parse, so installs are not checksum-verified.
