Extend Nexus with official plugins
Nexus plugins are TypeScript modules that hook into the agent runtime, OpenCode or Claude Code. They add platform-aware behavior to your agentic workflows, from cost tracking to CI/CD integration. Distributed as source via nexus pull, no npm install required.
Claude Code is now a first-class runtime
Session Guard, Headroom Intercept, Compaction Plus, Routing Guard, and Cost Control also ship as Claude Code hooks: in Claude Code projects, nexus pull writes them and wires them into the Claude Code settings, or they come with the nexus-core Claude Code plugin. The plugin repo was renamed from nexus-oc-plugins to nexus-runtime-plugins to reflect this.

How Plugins Work
Pull
Run nexus pull in your project. The CLI downloads plugin source files into .opencode/plugins/.
Load
OpenCode auto-discovers plugins on startup. Each plugin registers hooks, tools, and metadata, no config needed.
Execute
Hooks fire on runtime events (compaction, idle, etc.). Tools become available to agents. Everything is auditable via Nexus sessions.
