+# opencode-config
+
+## TLDR
+Template config + plugins injected into every OpenCode instance that CodeNomad launches. It provides a CodeNomad bridge plugin for local event exchange between the CLI server and opencode.
+
+## What it is
+A packaged config directory that CodeNomad copies into `~/.config/codenomad/opencode-config` for production builds or uses directly in dev. OpenCode autoloads any `plugin/*.ts` or `plugin/*.js` from this directory.
+
+## How it works
+- CodeNomad sets `OPENCODE_CONFIG_DIR` when spawning each opencode instance (`packages/server/src/workspaces/manager.ts`).
+- This template is synced from `packages/opencode-config` (`packages/server/src/opencode-config.ts`, `packages/server/scripts/copy-opencode-config.mjs`).
+- OpenCode autoloads plugins from `plugin/` (`packages/opencode-config/plugin/codenomad.ts`).
+- The `CodeNomadPlugin` reads `CODENOMAD_INSTANCE_ID` + `CODENOMAD_BASE_URL`, connects to `GET /workspaces/:id/plugin/events`, and posts to `POST /workspaces/:id/plugin/event` (`packages/opencode-config/plugin/lib/client.ts`).
+- The server exposes the plugin routes and maps events into the UI SSE pipeline (`packages/server/src/server/routes/plugin.ts`, `packages/server/src/plugins/handlers.ts`).
+
+## Expectations
+- Local-only bridge (no auth/token yet).
+- Plugin must fail startup if it cannot connect after 3 retries.
+- Keep plugin entrypoints thin; put shared logic under `plugin/lib/` to avoid autoloaded helpers.
+- Keep event shapes small and explicit; use `type` + `properties` only.
+
+## Ideas
+- Add feature modules under `plugin/lib/features/` (tool lifecycle, permission prompts, custom commands).
+- Expand `/workspaces/:id/plugin/*` with dedicated endpoints as needed.
+- Promote stable event shapes and version tags once the protocol settles.
+
+## Pointers
+- Plugin entry: `packages/opencode-config/plugin/codenomad.ts`
+- Plugin client: `packages/opencode-config/plugin/lib/client.ts`
+- Plugin server routes: `packages/server/src/server/routes/plugin.ts`
+- Plugin event handling: `packages/server/src/plugins/handlers.ts`
+- Workspace env injection: `packages/server/src/workspaces/manager.ts`
