+# HttpApi migration
+
+Practical notes for an eventual migration of `packages/opencode` server routes from the current Hono handlers to Effect `HttpApi`, either as a full replacement or as a parallel surface.
+
+## Goal
+
+Use Effect `HttpApi` where it gives us a better typed contract for:
+
+- route definition
+- request decoding and validation
+- typed success and error responses
+- OpenAPI generation
+- handler composition inside Effect
+
+This should be treated as a later-stage HTTP boundary migration, not a prerequisite for ongoing service, route-handler, or schema work.
+
+## Core model
+
+`HttpApi` is definition-first.
+
+- `HttpApi` is the root API
+- `HttpApiGroup` groups related endpoints
+- `HttpApiEndpoint` defines a single route and its request / response schemas
+- handlers are implemented separately from the contract
+
+This is a better fit once route inputs and outputs are already moving toward Effect Schema-first models.
+
+## Why it is relevant here
+
+The current route-effectification work is already pushing handlers toward:
+
+- one `AppRuntime.runPromise(Effect.gen(...))` body
+- yielding services from context
+- using typed Effect errors instead of Promise wrappers
+
+That work is a good prerequisite for `HttpApi`. Once the handler body is already a composed Effect, the remaining migration is mostly about replacing the Hono route declaration and validator layer.
+
+## What HttpApi gives us
+
+### Contracts
+
+Request params, query, payload, success payloads, and typed error payloads are declared in one place using Effect Schema.
+
+### Validation and decoding
+
+Incoming data is decoded through Effect Schema instead of hand-maintained Zod validators per route.
+
+### OpenAPI
+
+`HttpApi` can derive OpenAPI from the API definition, which overlaps with the current `describeRoute(...)` and `resolver(...)` pattern.
+
+### Typed errors
+
+`Schema.TaggedErrorClass` maps naturally to endpoint error contracts.
+
+## Likely fit for opencode
+
+Best fit first:
+
+- JSON request / response endpoints
+- route groups that already mostly delegate into services
+- endpoints whose request and response models can be defined with Effect Schema
+
+Harder / later fit:
+
+- SSE endpoints
+- websocket endpoints
+- streaming handlers
+- routes with heavy Hono-specific middleware assumptions
+
+## Current blockers and gaps
+
+### Schema split
+
+Many route boundaries still use Zod-first validators. That does not block all experimentation, but full `HttpApi` adoption is easier after the domain and boundary types are more consistently Schema-first with `.zod` compatibility only where needed.
+
+### Mixed handler styles
+
+Many current `server/instance/*.ts` handlers still call async facades directly. Migrating those to composed `Effect.gen(...)` handlers is the low-risk step to do first.
+
+### Non-JSON routes
+
+The server currently includes SSE, websocket, and streaming-style endpoints. Those should not be the first `HttpApi` targets.
+
+### Existing Hono integration
+
+The current server composition, middleware, and docs flow are Hono-centered today. That suggests a parallel or incremental adoption plan is safer than a flag day rewrite.
+
+## Recommended strategy
+
+### 1. Finish the prerequisites first
+
+- continue route-handler effectification in `server/instance/*.ts`
+- continue schema migration toward Effect Schema-first DTOs and errors
+- keep removing service facades
+
+### 2. Start with one parallel group
+
+Introduce one small `HttpApi` group for plain JSON endpoints only. Good initial candidates are the least stateful endpoints in:
+
+- `server/instance/question.ts`
+- `server/instance/provider.ts`
+- `server/instance/permission.ts`
+
+Avoid `session.ts`, SSE, websocket, and TUI-facing routes first.
+
+### 3. Reuse existing services
+
+Do not re-architect business logic during the HTTP migration. `HttpApi` handlers should call the same Effect services already used by the Hono handlers.
+
+### 4. Run in parallel before replacing
+
+Prefer mounting an experimental `HttpApi` surface alongside the existing Hono routes first. That lowers migration risk and lets us compare:
+
+- handler ergonomics
+- OpenAPI output
+- auth and middleware integration
+- test ergonomics
+
+### 5. Migrate JSON route groups gradually
+
+If the parallel slice works well, migrate additional JSON route groups one at a time. Leave streaming-style endpoints on Hono until there is a clear reason to move them.
+
+## Proposed first steps
+
+- [ ] add one small spike that defines an `HttpApi` group for a simple JSON route set
+- [ ] use Effect Schema request / response types for that slice
+- [ ] keep the underlying service calls identical to the current handlers
+- [ ] compare generated OpenAPI against the current Hono/OpenAPI setup
+- [ ] document how auth, instance lookup, and error mapping would compose in the new stack
+- [ ] decide after the spike whether `HttpApi` should stay parallel, replace only some groups, or become the long-term default
+
+## Rule of thumb
+
+Do not start with the hardest route file.
+
+If `HttpApi` is adopted here, it should arrive after the handler body is already Effect-native and after the relevant request / response models have moved to Effect Schema.

+## Tool migration
 
-### Tool migration details
-
-With `Tool.Info.init()` now effectful, use this transitional pattern for migrated tools that still need Promise-based boundaries internally:
-
-- `Tool.defineEffect(...)` should `yield*` the services the tool depends on and close over them in the returned tool definition.
-- Keep the bridge at the Promise boundary only inside the tool body when required by external APIs. Do not return Promise-based init callbacks from `Tool.define()`.
-- If a tool starts requiring new services, wire them into `ToolRegistry.defaultLayer` so production callers resolve the same dependencies as tests.
-
-Tool tests should use the existing Effect helpers in `packages/opencode/test/lib/effect.ts`:
-
-- Use `testEffect(...)` / `it.live(...)` instead of creating fake local wrappers around effectful tools.
-- Yield the real tool export, then initialize it: `const info = yield* ReadTool`, `const tool = yield* info.init()`.
-- Run tests inside a real instance with `provideTmpdirInstance(...)` or `provideInstance(tmpdirScoped(...))` so instance-scoped services resolve exactly as they do in production.
-

+# Route handler effectification
+
+Practical reference for converting server route handlers in `packages/opencode` to a single `AppRuntime.runPromise(Effect.gen(...))` body.
+
+## Goal
+
+Route handlers should wrap their entire body in a single `AppRuntime.runPromise(Effect.gen(...))` call, yielding services from context rather than calling facades one-by-one.
+
+This eliminates multiple `runPromise` round-trips and lets handlers compose naturally.
+
+```ts
+// Before - one facade call per service
+;async (c) => {
+  await SessionRunState.assertNotBusy(id)
+  await Session.removeMessage({ sessionID: id, messageID })
+  return c.json(true)
+}
+
+// After - one Effect.gen, yield services from context
+;async (c) => {
+  await AppRuntime.runPromise(
+    Effect.gen(function* () {
+      const state = yield* SessionRunState.Service
+      const session = yield* Session.Service
+      yield* state.assertNotBusy(id)
+      yield* session.removeMessage({ sessionID: id, messageID })
+    }),
+  )
+  return c.json(true)
+}
+```
+
+## Rules
+
+- Wrap the whole handler body in one `AppRuntime.runPromise(Effect.gen(...))` call when the handler is service-heavy.
+- Yield services from context instead of calling async facades repeatedly.
+- When independent service calls can run in parallel, use `Effect.all(..., { concurrency: "unbounded" })`.
+- Prefer one composed Effect body over multiple separate `runPromise(...)` calls in the same handler.
+
+## Current route files
+
+Current instance route files live under `src/server/instance`, not `server/routes`.
+
+The main migration targets are:
+
+- [ ] `server/instance/session.ts` — heaviest; still has many direct facade calls for Session, SessionPrompt, SessionRevert, SessionCompaction, SessionShare, SessionSummary, Agent, Bus
+- [ ] `server/instance/global.ts` — still has direct facade calls for Config and instance lifecycle actions
+- [ ] `server/instance/provider.ts` — still has direct facade calls for Config and Provider
+- [ ] `server/instance/question.ts` — partially converted; still worth tracking here until it consistently uses the composed style
+- [ ] `server/instance/pty.ts` — still calls Pty facades directly
+- [ ] `server/instance/experimental.ts` — mixed state; some handlers are already composed, others still use facades
+
+Additional route files that still participate in the migration:
+
+- [ ] `server/instance/index.ts` — Vcs, Agent, Skill, LSP, Format
+- [ ] `server/instance/file.ts` — Ripgrep, File, LSP
+- [ ] `server/instance/mcp.ts` — MCP facade-heavy
+- [ ] `server/instance/permission.ts` — Permission
+- [ ] `server/instance/workspace.ts` — Workspace
+- [ ] `server/instance/tui.ts` — Bus and Session
+- [ ] `server/instance/middleware.ts` — Session and Workspace lookups
+
+## Notes
+
+- Some handlers already use `AppRuntime.runPromise(Effect.gen(...))` in isolated places. Keep pushing those files toward one consistent style.
+- Route conversion is closely tied to facade removal. As services lose `makeRuntime`-backed async exports, route handlers should switch to yielding the service directly.

+# Schema migration
+
+Practical reference for migrating data types in `packages/opencode` from Zod-first definitions to Effect Schema with Zod compatibility shims.
+
+## Goal
+
+Use Effect Schema as the source of truth for domain models, IDs, inputs, outputs, and typed errors.
+
+Keep Zod available at existing HTTP, tool, and compatibility boundaries by exposing a `.zod` field derived from the Effect schema.
+
+## Preferred shapes
+
+### Data objects
+
+Use `Schema.Class` for structured data.
+
+```ts
+export class Info extends Schema.Class<Info>("Foo.Info")({
+  id: FooID,
+  name: Schema.String,
+  enabled: Schema.Boolean,
+}) {
+  static readonly zod = zod(Info)
+}
+```
+
+If the class cannot reference itself cleanly during initialization, use the existing two-step pattern:
+
+```ts
+const _Info = Schema.Struct({
+  id: FooID,
+  name: Schema.String,
+})
+
+export const Info = Object.assign(_Info, {
+  zod: zod(_Info),
+})
+```
+
+### Errors
+
+Use `Schema.TaggedErrorClass` for domain errors.
+
+```ts
+export class NotFoundError extends Schema.TaggedErrorClass<NotFoundError>()("FooNotFoundError", {
+  id: FooID,
+}) {}
+```
+
+### IDs and branded leaf types
+
+Keep branded/schema-backed IDs as Effect schemas and expose `static readonly zod` for compatibility when callers still expect Zod.
+
+## Compatibility rule
+
+During migration, route validators, tool parameters, and any existing Zod-based boundary should consume the derived `.zod` schema instead of maintaining a second hand-written Zod schema.
+
+The default should be:
+
+- Effect Schema owns the type
+- `.zod` exists only as a compatibility surface
+- new domain models should not start Zod-first unless there is a concrete boundary-specific need
+
+## When Zod can stay
+
+It is fine to keep a Zod-native schema temporarily when:
+
+- the type is only used at an HTTP or tool boundary
+- the validator depends on Zod-only transforms or behavior not yet covered by `zod()`
+- the migration would force unrelated churn across a large call graph
+
+When this happens, prefer leaving a short note or TODO rather than silently creating a parallel schema source of truth.
+
+## Ordering
+
+Migrate in this order:
+
+1. Shared leaf models and `schema.ts` files
+2. Exported `Info`, `Input`, `Output`, and DTO types
+3. Tagged domain errors
+4. Service-local internal models
+5. Route and tool boundary validators that can switch to `.zod`
+
+This keeps shared types canonical first and makes boundary updates mostly mechanical.
+
+## Checklist
+
+- [ ] Shared `schema.ts` leaf models are Effect Schema-first
+- [ ] Exported `Info` / `Input` / `Output` types use `Schema.Class` where appropriate
+- [ ] Domain errors use `Schema.TaggedErrorClass`
+- [ ] Migrated types expose `.zod` for back compatibility
+- [ ] Route and tool validators consume derived `.zod` instead of duplicate Zod definitions
+- [ ] New domain models default to Effect Schema first
+
+## Notes
+
+- Use `@/util/effect-zod` for all Schema -> Zod conversion.
+- Prefer one canonical schema definition. Avoid maintaining parallel Zod and Effect definitions for the same domain type.
+- Keep the migration incremental. Converting the domain model first is more valuable than converting every boundary in the same change.

+# Tool migration
+
+Practical reference for the current tool-migration state in `packages/opencode`.
+
+## Status
+
+`Tool.Def.execute` and `Tool.Info.init` already return `Effect` on this branch, and the built-in tool surface is now largely on the target shape.
+
+The current exported tools in `src/tool` all use `Tool.define(...)` with Effect-based initialization, and nearly all of them already build their tool body with `Effect.gen(...)` and `Effect.fn(...)`.
+
+So the remaining work is no longer "convert tools to Effect at all". The remaining work is mostly:
+
+1. remove Promise and raw platform bridges inside individual tool bodies
+2. swap tool internals to Effect-native services like `AppFileSystem`, `HttpClient`, and `ChildProcessSpawner`
+3. keep tests and callers aligned with `yield* info.init()` and real service graphs
+
+## Current shape
+
+`Tool.define(...)` is already the Effect-native helper here.
+
+- `init` is an `Effect`
+- `info.init()` returns an `Effect`
+- `execute(...)` returns an `Effect`
+
+That means a tool does not need a separate `Tool.defineEffect(...)` helper to count as migrated. A tool is effectively migrated when its init and execute path stay Effect-native, even if some internals still bridge to Promise-based or raw APIs.
+
+## Tests
+
+Tool tests should use the existing Effect helpers in `packages/opencode/test/lib/effect.ts`:
+
+- Use `testEffect(...)` / `it.live(...)` instead of creating fake local wrappers around effectful tools.
+- Yield the real tool export, then initialize it: `const info = yield* ReadTool`, `const tool = yield* info.init()`.
+- Run tests inside a real instance with `provideTmpdirInstance(...)` or `provideInstance(tmpdirScoped(...))` so instance-scoped services resolve exactly as they do in production.
+
+This keeps tool tests aligned with the production service graph and makes follow-up cleanup mostly mechanical.
+
+## Exported tools
+
+These exported tool definitions already exist in `src/tool` and are on the current Effect-native `Tool.define(...)` path:
+
+- [x] `apply_patch.ts`
+- [x] `bash.ts`
+- [x] `codesearch.ts`
+- [x] `edit.ts`
+- [x] `glob.ts`
+- [x] `grep.ts`
+- [x] `invalid.ts`
+- [x] `ls.ts`
+- [x] `lsp.ts`
+- [x] `multiedit.ts`
+- [x] `plan.ts`
+- [x] `question.ts`
+- [x] `read.ts`
+- [x] `skill.ts`
+- [x] `task.ts`
+- [x] `todo.ts`
+- [x] `webfetch.ts`
+- [x] `websearch.ts`
+- [x] `write.ts`
+
+Notes:
+
+- `batch.ts` is no longer a current tool file and should not be tracked here.
+- `truncate.ts` is an Effect service used by tools, not a tool definition itself.
+- `mcp-exa.ts`, `external-directory.ts`, and `schema.ts` are support modules, not standalone tool definitions.
+
+## Follow-up cleanup
+
+Most exported tools are already on the intended Effect-native shape. The remaining cleanup is narrower than the old checklist implied.
+
+Current spot cleanups worth tracking:
+
+- [ ] `read.ts` — still bridges to Node stream / `readline` helpers and Promise-based binary detection
+- [ ] `bash.ts` — already uses Effect child-process primitives; only keep tracking shell-specific platform bridges and parser/loading details as they come up
+- [ ] `webfetch.ts` — already uses `HttpClient`; remaining work is limited to smaller boundary helpers like HTML text extraction
+- [ ] `file/ripgrep.ts` — adjacent to tool migration; still has raw fs/process usage that affects `grep.ts` and `ls.ts`
+- [ ] `patch/index.ts` — adjacent to tool migration; still has raw fs usage behind patch application
+
+Notable items that are already effectively on the target path and do not need separate migration bullets right now:
+
+- `apply_patch.ts`
+- `grep.ts`
+- `write.ts`
+- `codesearch.ts`
+- `websearch.ts`
+- `ls.ts`
+- `multiedit.ts`
+- `edit.ts`
+
+## Filesystem notes
+
+Current raw fs users that still appear relevant here:
+
+- `tool/read.ts` — `fs.createReadStream`, `readline`
+- `file/ripgrep.ts` — `fs/promises`
+- `patch/index.ts` — `fs`, `fs/promises`

+
+## Testing With Effects
+
+Use `testEffect(...)` from `test/lib/effect.ts` for tests that exercise Effect services or Effect-based workflows.
+
+### Core Pattern
+
+```typescript
+import { describe, expect } from "bun:test"
+import { Effect, Layer } from "effect"
+import { provideTmpdirInstance } from "../fixture/fixture"
+import { testEffect } from "../lib/effect"
+
+const it = testEffect(Layer.mergeAll(MyService.defaultLayer))
+
+describe("my service", () => {
+  it.live("does the thing", () =>
+    provideTmpdirInstance(() =>
+      Effect.gen(function* () {
+        const svc = yield* MyService.Service
+        const out = yield* svc.run()
+        expect(out).toEqual("ok")
+      }),
+    ),
+  )
+})
+```
+
+### `it.effect` vs `it.live`
+
+- Use `it.effect(...)` when the test should run with `TestClock` and `TestConsole`.
+- Use `it.live(...)` when the test depends on real time, filesystem mtimes, child processes, git, locks, or other live OS behavior.
+- Most integration-style tests in this package use `it.live(...)`.
+
+### Effect Fixtures
+
+Prefer the Effect-aware helpers from `fixture/fixture.ts` instead of building a manual runtime in each test.
+
+- `tmpdirScoped(options?)` creates a scoped temp directory and cleans it up when the Effect scope closes.
+- `provideInstance(dir)(effect)` is the low-level helper. It does not create a directory; it just runs an Effect with `Instance.current` bound to `dir`.
+- `provideTmpdirInstance((dir) => effect, options?)` is the convenience helper. It creates a temp directory, binds it as the active instance, and disposes the instance on cleanup.
+- `provideTmpdirServer((input) => effect, options?)` does the same, but also provides the test LLM server.
+
+Use `provideTmpdirInstance(...)` by default when a test only needs one temp instance. Use `tmpdirScoped()` plus `provideInstance(...)` when a test needs multiple directories, custom setup before binding, or needs to switch instance context within one test.
+
+### Style
+
+- Define `const it = testEffect(...)` near the top of the file.
+- Keep the test body inside `Effect.gen(function* () { ... })`.
+- Yield services directly with `yield* MyService.Service` or `yield* MyTool`.
+- Avoid custom `ManagedRuntime`, `attach(...)`, or ad hoc `run(...)` wrappers when `testEffect(...)` already provides the runtime.
+- When a test needs instance-local state, prefer `provideTmpdirInstance(...)` or `provideInstance(...)` over manual `Instance.provide(...)` inside Promise-style tests.
