 - Not coupled to any provider. Although we recommend the models we provide through [OpenCode Zen](https://opencode.ai/zen), OpenCode can be used with Claude, OpenAI, Google, or even local models. As models evolve, the gaps between them will close and pricing will drop, so being provider-agnostic is important.

@@ -43,37 +42,3 @@ Instructions to follow when writing Effect.
 ## Errors
 
 - In `Effect.gen/fn`, prefer `yield* new MyError(...)` over `yield* Effect.fail(new MyError(...))` for direct early-failure branches.
-
-## Instance-scoped Effect services
-
-Services that need per-directory lifecycle (created/destroyed per instance) go through the `Instances` LayerMap:
-
-1. Define a `ServiceMap.Service` with a `static readonly layer` (see `FileWatcherService`, `QuestionService`, `PermissionService`, `ProviderAuthService`).
-2. Add it to `InstanceServices` union and `Layer.mergeAll(...)` in `src/effect/instances.ts`.
-3. Use `InstanceContext` inside the layer to read `directory` and `project` instead of `Instance.*` globals.
-4. Call from legacy code via `runPromiseInstance(MyService.use((s) => s.method()))`.
-
-### Instance.bind — ALS context for native callbacks
-
-`Instance.bind(fn)` captures the current Instance AsyncLocalStorage context and returns a wrapper that restores it synchronously when called.
-
-**Use it** when passing callbacks to native C/C++ addons (`@parcel/watcher`, `node-pty`, native `fs.watch`, etc.) that need to call `Bus.publish`, `Instance.state()`, or anything that reads `Instance.directory`.
-
-**Don't need it** for `setTimeout`, `Promise.then`, `EventEmitter.on`, or Effect fibers — Node.js ALS propagates through those automatically.
-
-```typescript
-// Native addon callback — needs Instance.bind
-const cb = Instance.bind((err, evts) => {
-  Bus.publish(MyEvent, { ... })
-})
-nativeAddon.subscribe(dir, cb)
-```
-
-## Flag → Effect.Config migration
-
-Flags in `src/flag/flag.ts` are being migrated from static `truthy(...)` reads to `Config.boolean(...).pipe(Config.withDefault(false))` as their consumers get effectified.
-
-- Effectful flags return `Config<boolean>` and are read with `yield*` inside `Effect.gen`.
-- The default `ConfigProvider` reads from `process.env`, so env vars keep working.
-- Tests can override via `ConfigProvider.layer(ConfigProvider.fromUnknown({ ... }))`.
-- Keep all flags in `flag.ts` as the single registry — just change the implementation from `truthy()` to `Config.boolean()` when the consumer moves to Effect.
