opencode: lazy-load top-level CLI commands

The CLI imports every top-level command before argument parsing has
decided which handler will run. This makes simple invocations pay for
the full command graph up front and slows down the default startup path.

Parse the root argv first and load only the command module that matches
the selected top-level command. Keep falling back to the default TUI
path for non-command positionals, and preserve root help, version and
completion handling

+### 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.
+
+This keeps migrated tool tests aligned with the production service graph today, and makes the eventual `Tool.Info` → `Effect` cleanup mostly mechanical later.

 ## Route handler effectification
 
-Route-handler migration guidance and checklist live in `routes.md`.
+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)
+}
+```
+
+When migrating, always use `{ concurrency: "unbounded" }` with `Effect.all` — route handlers should run independent service calls in parallel, not sequentially.
+
+Route files to convert (each handler that calls facades should be wrapped):
+
+- [ ] `server/routes/session.ts` — heaviest; uses Session, SessionPrompt, SessionRevert, SessionCompaction, SessionShare, SessionSummary, SessionRunState, Agent, Permission, Bus
+- [ ] `server/routes/global.ts` — uses Config, Project, Provider, Vcs, Snapshot, Agent
+- [ ] `server/routes/provider.ts` — uses Provider, Auth, Config
+- [ ] `server/routes/question.ts` — uses Question
+- [ ] `server/routes/pty.ts` — uses Pty

-# 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.

-      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`
