Summary

Ports the CrewBee plugin adapter to the OpenCode V2 plugin API so the plugin loads on OpenCode 2.x, while keeping the V1 path working through a dual-shape entrypoint.

On OpenCode V2 (tested with 2.1.3) the current release fails to load with:

failed to load plugin target=crewbee
cause=PluginModule.LoadError: Plugin must export a default definition with an id and an effect or setup function.

V2 does not run V1 plugin implementations (see the official migration guide), so the adapter is provided as a new V2 module alongside the preserved V1 implementation.

Changes

• src/adapters/opencode/v2/ (new): V2 adapter implementation
  • plugin.ts — Plugin.define({ id, setup(ctx) }) entrypoint wiring transforms, hooks, and event subscription
  • session-client.ts — V2 session/message client shims (messages via session.context, prompt, abort → interrupt)
  • tool-registration.ts — registers delegate tools through ctx.tool.transform with zod ValueSchema
  • agent-definition.ts — projects CrewBee agents via ctx.agent.transform
  • models.ts — available-model discovery via ctx.model.list()
  • permissions.ts — permission mapping for V2 agent definitions
  • logging.ts — console-based logging (V2 has no client.app.log)
• src/adapters/opencode/plugin.ts — dual-shape default export: V2 setup + V1 server
• src/adapters/opencode/plugin-v1.ts — previous V1 plugin body preserved as server()
• src/adapters/opencode/tool-hooks.ts — execute.before/execute.after adapted to V2 hook shapes
• src/install/opencode-config-file.ts — plugin entry written to V2 plugins config key (with plugin migration)
• src/update/refresh.ts — V2 logging/context adaptation
• package.json — targets OpenCode 2.2.0 SDK (@opencode/plugin)
• docs/developer/opencode-v2-port.md — full porting notes (V1 → V2 API mapping)

Testing

• npm run typecheck, npm run build, npm test
• Empirical load test against OpenCode 2.x: plugin loads, agents projected, delegate tools registered
