+name: effect
+description: Answer questions about the Effect framework
+---
+
+# Effect
+
+This codebase uses Effect, a framework for writing typescript.
+
+## How to Answer Effect Questions
+
+1. Clone the Effect repository: `https://github.com/Effect-TS/effect-smol` to
+   `.opencode/references/effect-smol` in this project NOT the skill folder.
+2. Use the explore agent to search the codebase for answers about Effect patterns, APIs, and concepts
+3. Provide responses based on the actual Effect source code and documentation
+
+## Guidelines
+
+- Always use the explore agent with the cloned repository when answering Effect-related questions
+- Reference specific files and patterns found in the Effect codebase
+- Do not answer from memory - always verify against the source

 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
+## Schema rule for HttpApi work
 
-- [ ] 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
+Every `HttpApi` slice should follow `specs/effect/schema.md` and the Schema -> Zod interop rule in `specs/effect/migration.md`.
+
+Default rule:
+
+- Effect Schema owns the type
+- `.zod` exists only as a compatibility surface
+- do not introduce a new hand-written Zod schema for a type that is already migrating to Effect Schema
+
+Practical implication for `HttpApi` migration:
+
+- if a route boundary already depends on a shared DTO, ID, input, output, or tagged error, migrate that model to Effect Schema first or in the same change
+- if an existing Hono route or tool still needs Zod, derive it with `@/util/effect-zod`
+- avoid maintaining parallel Zod and Effect definitions for the same request or response type
+
+Ordering for a route-group migration:
+
+1. move implicated shared `schema.ts` leaf types to Effect Schema first
+2. move exported `Info` / `Input` / `Output` route DTOs to Effect Schema
+3. move tagged route-facing errors to `Schema.TaggedErrorClass` where needed
+4. switch existing Zod boundary validators to derived `.zod`
+5. define the `HttpApi` contract from the canonical Effect schemas
+
+Temporary exception:
+
+- it is acceptable to keep a route-local Zod schema for the first spike only when the type is boundary-local and migrating it would create unrelated churn
+- if that happens, leave a short note so the type does not become a permanent second source of truth
+
+## First vertical slice
+
+The first `HttpApi` spike should be intentionally small and repeatable.
+
+Chosen slice:
+
+- group: `question`
+- endpoints: `GET /question` and `POST /question/:requestID/reply`
+
+Non-goals:
+
+- no `session` routes
+- no SSE or websocket routes
+- no auth redesign
+- no broad service refactor
+
+Behavior rule:
+
+- preserve current runtime behavior first
+- treat semantic changes such as introducing new `404` behavior as a separate follow-up unless they are required to make the contract honest
+
+Add `POST /question/:requestID/reject` only after the first two endpoints work cleanly.
+
+## Repeatable slice template
+
+Use the same sequence for each route group.
+
+1. Pick one JSON-only route group that already mostly delegates into services.
+2. Identify the shared DTOs, IDs, and errors implicated by that slice.
+3. Apply the schema migration ordering above so those types are Effect Schema-first.
+4. Define the `HttpApi` contract separately from the handlers.
+5. Implement handlers by yielding the existing service from context.
+6. Mount the new surface in parallel under an experimental prefix.
+7. Add one end-to-end test and one OpenAPI-focused test.
+8. Compare ergonomics before migrating the next endpoint.
+
+Rule of thumb:
+
+- migrate one route group at a time
+- migrate one or two endpoints first, not the whole file
+- keep business logic in the existing service
+- keep the first spike easy to delete if the experiment is not worth continuing
+
+## Example structure
+
+Placement rule:
+
+- keep `HttpApi` code under `src/server`, not `src/effect`
+- `src/effect` should stay focused on runtimes, layers, instance state, and shared Effect plumbing
+- place each `HttpApi` slice next to the HTTP boundary it serves
+- for instance-scoped routes, prefer `src/server/instance/httpapi/*`
+- if control-plane routes ever migrate, prefer `src/server/control/httpapi/*`
+
+Suggested file layout for a repeatable spike:
+
+- `src/server/instance/httpapi/question.ts`
+- `src/server/instance/httpapi/index.ts`
+- `test/server/question-httpapi.test.ts`
+- `test/server/question-httpapi-openapi.test.ts`
+
+Suggested responsibilities:
+
+- `question.ts` defines the `HttpApi` contract and `HttpApiBuilder.group(...)` handlers for the experimental slice
+- `index.ts` combines experimental `HttpApi` groups and exposes the mounted handler or layer
+- `question-httpapi.test.ts` proves the route works end-to-end against the real service
+- `question-httpapi-openapi.test.ts` proves the generated OpenAPI is acceptable for the migrated endpoints
+
+## Example migration shape
+
+Each route-group spike should follow the same shape.
+
+### 1. Contract
+
+- define an experimental `HttpApi`
+- define one `HttpApiGroup`
+- define endpoint params, payload, success, and error schemas from canonical Effect schemas
+- annotate summary, description, and operation ids explicitly so generated docs are stable
+
+### 2. Handler layer
+
+- implement with `HttpApiBuilder.group(api, groupName, ...)`
+- yield the existing Effect service from context
+- keep handler bodies thin
+- keep transport mapping at the HTTP boundary only
+
+### 3. Mounting
+
+- mount under an experimental prefix such as `/experimental/httpapi`
+- keep existing Hono routes unchanged
+- expose separate OpenAPI output for the experimental slice first
+
+### 4. Verification
+
+- seed real state through the existing service
+- call the experimental endpoints
+- assert that the service behavior is unchanged
+- assert that the generated OpenAPI contains the migrated paths and schemas
+
+## Boundary composition
+
+The first slices should keep the existing outer server composition and only replace the route contract and handler layer.
+
+### Auth
+
+- keep `AuthMiddleware` at the outer Hono app level
+- do not duplicate auth checks inside each `HttpApi` group for the first parallel slices
+- treat auth as an already-satisfied transport concern before the request reaches the `HttpApi` handler
+
+Practical rule:
+
+- if a route is currently protected by the shared server middleware stack, the experimental `HttpApi` route should stay mounted behind that same stack
+
+### Instance and workspace lookup
+
+- keep `WorkspaceRouterMiddleware` as the source of truth for resolving `directory`, `workspace`, and session-derived workspace context
+- let that middleware provide `Instance.current` and `WorkspaceContext` before the request reaches the `HttpApi` handler
+- keep the `HttpApi` handlers unaware of path-to-instance lookup details when the existing Hono middleware already handles them
+
+Practical rule:
+
+- `HttpApi` handlers should yield services from context and assume the correct instance has already been provided
+- only move instance lookup into the `HttpApi` layer if we later decide to migrate the outer middleware boundary itself
+
+### Error mapping
+
+- keep domain and service errors typed in the service layer
+- declare typed transport errors on the endpoint only when the route can actually return them intentionally
+- prefer explicit endpoint-level error schemas over relying on the outer Hono `ErrorMiddleware` for expected route behavior
+
+Practical rule:
+
+- request decoding failures should remain transport-level `400`s
+- storage or lookup failures that are part of the route contract should be declared as typed endpoint errors
+- unexpected defects can still fall through to the outer error middleware while the slice is experimental
+
+For the current parallel slices, this means:
+
+- auth still composes outside `HttpApi`
+- instance selection still composes outside `HttpApi`
+- success payloads should be schema-defined from canonical Effect schemas
+- known route errors should be modeled at the endpoint boundary incrementally instead of all at once
+
+## Exit criteria for the spike
+
+The first slice is successful if:
+
+- the endpoints run in parallel with the current Hono routes
+- the handlers reuse the existing Effect service
+- request decoding and response shapes are schema-defined from canonical Effect schemas
+- any remaining Zod boundary usage is derived from `.zod` or clearly temporary
+- OpenAPI is generated from the `HttpApi` contract
+- the tests are straightforward enough that the next slice feels mechanical
+
+## Learnings from the question slice
+
+The first parallel `question` spike gave us a concrete pattern to reuse.
+
+- `Schema.Class` works well for route DTOs such as `Question.Request`, `Question.Info`, and `Question.Reply`.
+- scalar or collection schemas such as `Question.Answer` should stay as schemas and use helpers like `withStatics(...)` instead of being forced into classes.
+- if an `HttpApi` success schema uses `Schema.Class`, the handler or underlying service needs to return real schema instances rather than plain objects.
+- internal event payloads can stay anonymous when we want to avoid adding extra named OpenAPI component churn for non-route shapes.
+- the experimental slice should stay mounted in parallel and keep calling the existing service layer unchanged.
+- compare generated OpenAPI semantically at the route and schema level; in the current setup the exported OpenAPI paths do not include the outer Hono mount prefix.
+
+## Route inventory
+
+Status legend:
+
+- `done` - parallel `HttpApi` slice exists
+- `next` - good near-term candidate
+- `later` - possible, but not first wave
+- `defer` - not a good early `HttpApi` target
+
+Current instance route inventory:
+
+- `question` - `done`
+  endpoints in slice: `GET /question`, `POST /question/:requestID/reply`
+- `permission` - `done`
+  endpoints in slice: `GET /permission`, `POST /permission/:requestID/reply`
+- `provider` - `next`
+  best next endpoint: `GET /provider/auth`
+  later endpoint: `GET /provider`
+  defer first-wave OAuth mutations
+- `config` - `next`
+  best next endpoint: `GET /config/providers`
+  later endpoint: `GET /config`
+  defer `PATCH /config` for now
+- `project` - `later`
+  best small reads: `GET /project`, `GET /project/current`
+  defer git-init mutation first
+- `workspace` - `later`
+  best small reads: `GET /experimental/workspace/adaptor`, `GET /experimental/workspace`, `GET /experimental/workspace/status`
+  defer create/remove mutations first
+- `file` - `later`
+  good JSON-only candidate set, but larger than the current first-wave slices
+- `mcp` - `later`
+  has JSON-only endpoints, but interactive OAuth/auth flows make it a worse early fit
+- `session` - `defer`
+  large, stateful, mixes CRUD with prompt/shell/command/share/revert flows and a streaming route
+- `event` - `defer`
+  SSE only
+- `global` - `defer`
+  mixed bag with SSE and process-level side effects
+- `pty` - `defer`
+  websocket-heavy route surface
+- `tui` - `defer`
+  queue-style UI bridge, weak early `HttpApi` fit
+
+Recommended near-term sequence after the first spike:
+
+1. `provider` auth read endpoint
+2. `config` providers read endpoint
+3. `project` read endpoints
+4. `workspace` read endpoints
+
+## Checklist
+
+- [x] add one small spike that defines an `HttpApi` group for a simple JSON route set
+- [x] use Effect Schema request / response types for that slice
+- [x] keep the underlying service calls identical to the current handlers
+- [x] compare generated OpenAPI against the current Hono/OpenAPI setup
+- [x] 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

+- [ ] `config/tui.ts` - finish the internal Effect migration after the `Instance.state(...)` removal.
+      Keep the current precedence and migration semantics intact while converting the remaining internal async helpers (`loadState`, `mergeFile`, `loadFile`, `load`) to `Effect.gen(...)` / `Effect.fn(...)`.
+- [ ] `config/tui.ts` callers - once the internal service is stable, migrate plain async callers to use `TuiConfig.Service` directly where that actually simplifies the code.
+      Likely first callers: `cli/cmd/tui/attach.ts`, `cli/cmd/tui/thread.ts`, `cli/cmd/tui/plugin/runtime.ts`.
+- [ ] `env/index.ts` - move the last production `Instance.state(...)` usage onto `InstanceState` (or its replacement) so `Instance.state` can be deleted.
+
+## ConfigPaths
+
+- [ ] `config/paths.ts` - split pure helpers from effectful helpers.
+      Keep `fileInDirectory(...)` as a plain function.
+- [ ] `config/paths.ts` - add a `ConfigPaths.Service` for the effectful operations so callers do not inherit `AppFileSystem.Service` directly.
+      Initial service surface should cover:
+  - `projectFiles(...)`
+  - `directories(...)`
+  - `readFile(...)`
+  - `parseText(...)`
+- [ ] `config/config.ts` - switch internal config loading from `Effect.promise(() => ConfigPaths.*(...))` to `yield* paths.*(...)` once the service exists.
+- [ ] `config/tui.ts` - switch TUI config loading from async `ConfigPaths.*` wrappers to the `ConfigPaths.Service` once that service exists.
+- [ ] `config/tui-migrate.ts` - decide whether to leave this as a plain async module using wrapper functions or effectify it fully after `ConfigPaths.Service` lands.
+
+## Instance cleanup
+
+- [ ] `project/instance.ts` - remove `Instance.state(...)` once `env/index.ts` is migrated.
+- [ ] `project/state.ts` - delete the bespoke per-instance state helper after the last production caller is gone.
+- [ ] `test/project/state.test.ts` - replace or delete the old `Instance.state(...)` tests after the removal.
+
+## Notes
+
+- Prefer small, semantics-preserving config migrations. Config precedence, legacy key migration, and plugin origin tracking are easy to break accidentally.
+- When changing config loading internals, rerun the config and TUI suites first before broad package sweeps.

+# Server package extraction
+
+Practical reference for extracting a future `packages/server` from the current `packages/opencode` monolith while `packages/core` is still being migrated to Effect.
+
+This document is intentionally execution-oriented.
+
+It should give an agent enough context to land one incremental PR at a time without needing to rediscover the package strategy, route migration rules, or current constraints.
+
+## Goal
+
+Create `packages/server` as the home for:
+
+- HTTP contract definitions
+- HTTP handler implementations
+- OpenAPI generation
+- eventual embeddable server APIs for Node apps
+
+Do this without blocking on the full `packages/core` extraction.
+
+## Future state
+
+Target package layout:
+
+- `packages/core` - all opencode services, Effect-first source of truth
+- `packages/server` - opencode server, with separate contract and implementation, still producing `openapi.json`
+- `packages/cli` - TUI + CLI entrypoints
+- `packages/sdk` - generated from the server OpenAPI spec, may add higher-level wrappers
+- `packages/plugin` - generated or semi-hand-rolled non-Effect package built from core plugin definitions
+
+Desired user stories:
+
+- import from `core` and build a custom agent or app-specific runtime
+- import from `server` and embed the full opencode server into an existing Node app
+- spawn the CLI and talk to the server through that boundary
+
+## Current state
+
+Everything still lives in `packages/opencode`.
+
+Important current facts:
+
+- there is no `packages/core` or `packages/cli` workspace yet
+- `packages/server` now exists as a minimal scaffold package, but it does not own any real route contracts, handlers, or runtime composition yet
+- the main host server is still Hono-based in `src/server/server.ts`
+- current OpenAPI generation is Hono-based through `Server.openapi()` and `cli/cmd/generate.ts`
+- the Effect runtime and app layer are centralized in `src/effect/app-runtime.ts` and `src/effect/run-service.ts`
+- there is already one experimental Effect `HttpApi` slice at `src/server/instance/httpapi/question.ts`
+- that experimental slice is mounted under `/experimental/httpapi/question`
+- that experimental slice already has an end-to-end test at `test/server/question-httpapi.test.ts`
+
+This means the package split should start from an extraction path, not from greenfield package ownership.
+
+## Structural reference
+
+Use `anomalyco/opentunnel` as the structural reference for `packages/server`.
+
+The important pattern there is:
+
+- `packages/core` owns services and domain schemas
+- `packages/server/src/definition/*` owns pure `HttpApi` contracts
+- `packages/server/src/api/*` owns `HttpApiBuilder.group(...)` implementations and server-side middleware wiring
+- `packages/server/src/index.ts` becomes the composition root only after the server package really owns runtime hosting
+
+Relevant `opentunnel` files:
+
+- `packages/server/src/definition/index.ts`
+- `packages/server/src/definition/tunnel.ts`
+- `packages/server/src/api/index.ts`
+- `packages/server/src/api/tunnel.ts`
+- `packages/server/src/api/client.ts`
+- `packages/server/src/index.ts`
+
+The intended direction here is the same, but the current `opencode` package split is earlier in the migration.
+
+That means:
+
+- we should follow the same `definition` and `api` naming
+- we should keep contract and implementation as separate modules from the start
+- we should postpone the runtime composition root until `packages/core` exists enough to support it cleanly
+
+## Key decision
+
+Start `packages/server` as a contract and implementation package only.
+
+Do not make it the runtime host yet.
+
+Why:
+
+- `packages/core` does not exist yet
+- the current server host still lives in `packages/opencode`
+- moving host ownership immediately would force a large package and runtime shuffle while Effect service extraction is still in flight
+- if `packages/server` imports services from `packages/opencode` while `packages/opencode` imports `packages/server` to host routes, we create a package cycle immediately
+
+Short version:
+
+1. create `packages/server`
+2. move pure `HttpApi` contracts there
+3. move handler factories there
+4. keep `packages/opencode` as the temporary Hono host
+5. merge `packages/server` OpenAPI with the legacy Hono OpenAPI during the transition
+6. move server hosting later, after `packages/core` exists enough
+
+## Dependency rule
+
+Phase 1 rule:
+
+- `packages/server` must not import from `packages/opencode`
+
+Allowed in phase 1:
+
+- `packages/opencode` imports `packages/server`
+- `packages/server` accepts host-provided services, layers, or callbacks as inputs
+- `packages/server` may temporarily own transport-local placeholder schemas when a canonical shared schema does not exist yet
+
+Future rule after `packages/core` exists:
+
+- `packages/server` imports from `packages/core`
+- `packages/cli` imports from `packages/server` and `packages/core`
+- `packages/opencode` shrinks or disappears as package responsibilities are fully split
+
+## HttpApi model
+
+Use Effect v4 `HttpApi` as the source of truth for migrated HTTP routes.
+
+Important properties from the current `effect` / `effect-smol` model:
+
+- `HttpApi`, `HttpApiGroup`, and `HttpApiEndpoint` are pure contract definitions
+- handlers are implemented separately with `HttpApiBuilder.group(...)`
+- OpenAPI can be generated from the contract alone
+- auth and middleware can later be modeled with `HttpApiMiddleware.Service`
+- SSE and websocket routes are not good first-wave `HttpApi` targets
+
+This package split should preserve that separation explicitly.
+
+Default shape for migrated routes:
+
+- contract lives in `packages/server/src/definition/*`
+- implementation lives in `packages/server/src/api/*`
+- host mounting stays outside for now
+
+## OpenAPI rule
+
+During the transition there is still one spec artifact.
+
+Default rule:
+
+- `packages/server` generates OpenAPI from `HttpApi` contract
+- `packages/opencode` keeps generating legacy OpenAPI from Hono routes
+- the temporary exported server spec is a merged document
+- `packages/sdk` continues consuming one `openapi.json`
+
+Merge safety rules:
+
+- fail on duplicate `path + method`
+- fail on duplicate `operationId`
+- prefer explicit summary, description, and operation ids on all new `HttpApi` endpoints
+
+Practical implication:
+
+- do not make the SDK consume two specs
+- do not switch SDK generation to `packages/server` only until enough of the route surface has moved
+
+## Package shape
+
+Minimum viable `packages/server`:
+
+- `src/index.ts`
+- `src/definition/index.ts`
+- `src/definition/api.ts`
+- `src/definition/question.ts`
+- `src/api/index.ts`
+- `src/api/question.ts`
+- `src/openapi.ts`
+- `src/bridge/hono.ts`
+- `src/types.ts`
+
+Later additions, once there is enough real contract surface:
+
+- `src/api/client.ts`
+- runtime composition in `src/index.ts`
+
+Suggested initial exports:
+
+- `api`
+- `openapi`
+- `questionApi`
+- `makeQuestionHandler`
+
+Phase 1 responsibilities:
+
+- own pure API contracts
+- own handler factories for migrated slices
+- own contract-generated OpenAPI
+- expose host adapters needed by `packages/opencode`
+
+Phase 1 non-goals:
+
+- do not own `listen()`
+- do not own adapter selection
+- do not own global server middleware
+- do not own websocket or SSE transport
+- do not own process bootstrapping for CLI entrypoints
+
+## Current source inventory
+
+These files matter for the first phase.
+
+Current host and route composition:
+
+- `src/server/server.ts`
+- `src/server/control/index.ts`
+- `src/server/instance/index.ts`
+- `src/server/middleware.ts`
+- `src/server/adapter.bun.ts`
+- `src/server/adapter.node.ts`
+
+Current experimental `HttpApi` slice:
+
+- `src/server/instance/httpapi/question.ts`
+- `src/server/instance/httpapi/index.ts`
+- `src/server/instance/experimental.ts`
+- `test/server/question-httpapi.test.ts`
+
+Current OpenAPI flow:
+
+- `src/server/server.ts` via `Server.openapi()`
+- `src/cli/cmd/generate.ts`
+- `packages/sdk/js/script/build.ts`
+
+Current runtime and service layer:
+
+- `src/effect/app-runtime.ts`
+- `src/effect/run-service.ts`
+
+## Ownership rules
+
+Move first into `packages/server`:
+
+- the experimental `question` `HttpApi` slice
+- future `provider` and `config` JSON read slices
+- any new `HttpApi` route groups
+- transport-local OpenAPI generation for migrated routes
+
+Keep in `packages/opencode` for now:
+
+- `src/server/server.ts`
+- `src/server/control/index.ts`
+- `src/server/instance/*.ts`
+- `src/server/middleware.ts`
+- `src/server/adapter.*.ts`
+- `src/effect/app-runtime.ts`
+- `src/effect/run-service.ts`
+- all Effect services until they move to `packages/core`
+
+## Placeholder schema rule
+
+`packages/core` is allowed to lag behind.
+
+Until shared canonical schemas move to `packages/core`:
+
+- prefer importing existing Effect Schema DTOs from current locations when practical
+- if a route only needs a transport-local type and moving the canonical schema would create unrelated churn, allow a temporary server-local placeholder schema
+- if a placeholder is introduced, leave a short note so it does not become permanent
+
+The default rule from `schema.md` still applies:
+
+- Effect Schema owns the type
+- `.zod` is compatibility only
+- avoid parallel hand-written Zod and Effect definitions for the same migrated route shape
+
+## Host boundary rule
+
+Until host ownership moves:
+
+- auth stays at the outer Hono app level
+- compression stays at the outer Hono app level
+- CORS stays at the outer Hono app level
+- instance and workspace lookup stay at the current middleware layer
+- `packages/server` handlers should assume the host already provided the right request context
+- do not redesign host middleware just to land the package split
+
+This matches the current guidance in `http-api.md`:
+
+- keep auth outside the first parallel `HttpApi` slices
+- keep instance lookup outside the first parallel `HttpApi` slices
+- keep the first migrations transport-focused and semantics-preserving
+
+## Route selection rules
+
+Good early migration targets:
+
+- `question`
+- `provider` auth read endpoint
+- `config` providers read endpoint
+- small read-only instance routes
+
+Bad early migration targets:
+
+- `session`
+- `event`
+- `pty`
+- most `global` streaming or process-heavy routes
+- anything requiring websocket upgrade handling
+- anything that mixes many mutations and streaming in one file
+
+## First vertical slice
+
+The first slice for the package split is the existing experimental `question` group.
+
+Why `question` first:
+
+- it already exists as an experimental `HttpApi` slice
+- it already follows the desired contract and implementation split in one file
+- it is already mounted through the current Hono host
+- it already has an end-to-end test
+- it is JSON-only
+- it has low blast radius
+
+Use the first slice to prove:
+
+- package boundary
+- contract and implementation split
+- host mounting from `packages/opencode`
+- merged OpenAPI output
+- test ergonomics for future slices
+
+Do not broaden scope in the first slice.
+
+## Incremental migration order
+
+Use small PRs.
+
+Each PR should be easy to review, easy to revert, and should not mix extraction work with unrelated service refactors.
+
+### PR 1. Create `packages/server`
+
+Scope:
+
+- add the new workspace package
+- add package manifest and tsconfig
+- add empty `src/index.ts`, `src/definition/api.ts`, `src/definition/index.ts`, `src/api/index.ts`, `src/openapi.ts`, and supporting scaffolding
+
+Rules:
+
+- no production behavior changes
+- no host server changes yet
+- no imports from `packages/opencode` inside `packages/server`
+- prefer `opentunnel`-style naming from the start: `definition` for contracts, `api` for implementations
+
+Done means:
+
+- `packages/server` typechecks
+- the workspace can import it
+- the package boundary is in place for follow-up PRs
+
+### PR 2. Move the experimental question contract
+
+Scope:
+
+- extract the pure `HttpApi` contract from `src/server/instance/httpapi/question.ts`
+- place it in `packages/server/src/definition/question.ts`
+- aggregate it in `packages/server/src/definition/api.ts`
+- generate OpenAPI in `packages/server/src/openapi.ts`
+
+Rules:
+
+- contract only in this PR
+- no handler movement yet if that keeps the diff simpler
+- keep operation ids and docs metadata stable
+
+Done means:
+
+- question contract lives in `packages/server`
+- OpenAPI can be generated from contract alone
+- no runtime behavior changes yet
+
+### PR 3. Move the experimental question handler factory
+
+Scope:
+
+- extract the question `HttpApiBuilder.group(...)` implementation into `packages/server/src/api/question.ts`
+- expose it as a factory that accepts host-provided dependencies or wiring
+- add a small Hono bridge in `packages/server/src/bridge/hono.ts` if needed
+
+Rules:
+
+- `packages/server` must still not import from `packages/opencode`
+- handler code should stay thin and service-delegating
+- do not redesign the question service itself in this PR
+
+Done means:
+
+- `packages/server` can produce the experimental question handler
+- the package still stays cycle-free
+
+### PR 4. Mount `packages/server` question from `packages/opencode`
+
+Scope:
+
+- replace local experimental question route wiring in `packages/opencode`
+- keep the same mount path:
+- `/experimental/httpapi/question`
+- `/experimental/httpapi/question/doc`
+
+Rules:
+
+- no behavior change
+- preserve existing docs path
+- preserve current request and response shapes
+
+Done means:
+
+- existing question `HttpApi` test still passes
+- runtime behavior is unchanged
+- the current host server is now consuming `packages/server`
+
+### PR 5. Merge legacy and contract OpenAPI
+
+Scope:
+
+- keep `Server.openapi()` as the temporary spec entrypoint
+- generate legacy Hono spec
+- generate `packages/server` contract spec
+- merge them into one document
+- keep `cli/cmd/generate.ts` and `packages/sdk/js/script/build.ts` consuming one spec
+
+Rules:
+
+- fail loudly on duplicate `path + method`
+- fail loudly on duplicate `operationId`
+- do not silently overwrite one source with the other
+
+Done means:
+
+- one merged spec is produced
+- migrated question paths can come from `packages/server`
+- existing SDK generation path still works
+
+### PR 6. Add merged OpenAPI coverage
+
+Scope:
+
+- add one test for merged OpenAPI
+- assert both a legacy Hono route and a migrated `HttpApi` route exist
+
+Rules:
+
+- test the merged document, not just the `packages/server` contract spec in isolation
+- pick one stable legacy route and one stable migrated route
+
+Done means:
+
+- the merged-spec path is covered
+- future route migrations have a guardrail
+
+### PR 7. Migrate `GET /provider/auth`
+
+Scope:
+
+- add `GET /provider/auth` as the next `HttpApi` slice in `packages/server`
+- mount it in parallel from `packages/opencode`
+
+Why this route:
+
+- JSON-only
+- simple service delegation
+- small response shape
+- already listed as the best next `provider` candidate in `http-api.md`
+
+Done means:
+
+- route works through the current host
+- route appears in merged OpenAPI
+- no semantic change to provider auth behavior
+
+### PR 8. Migrate `GET /config/providers`
+
+Scope:
+
+- add `GET /config/providers` as a `HttpApi` slice in `packages/server`
+- mount it in parallel from `packages/opencode`
+
+Why this route:
+
+- JSON-only
+- read-only
+- low transport complexity
+- already listed as the best next `config` candidate in `http-api.md`
+
+Done means:
+
+- route works unchanged
+- route appears in merged OpenAPI
+
+### PR 9+. Migrate small read-only instance routes
+
+Candidate order:
+
+1. `GET /path`
+2. `GET /vcs`
+3. `GET /vcs/diff`
+4. `GET /command`
+5. `GET /agent`
+6. `GET /skill`
+
+Rules:
+
+- one or two endpoints per PR
+- prefer read-only routes first
+- keep outer middleware unchanged
+- keep business logic in the existing service layer
+
+Done means for each PR:
+
+- contract lives in `packages/server`
+- handler lives in `packages/server`
+- route is mounted from the current host
+- route appears in merged OpenAPI
+- behavior remains unchanged
+
+### Later PR. Move host ownership into `packages/server`
+
+Only start this after there is enough `packages/core` surface to depend on directly.
+
+Scope:
+
+- move server composition into `packages/server`
+- add embeddable APIs such as `createServer(...)`, `listen(...)`, or `createApp(...)`
+- move adapter selection and server startup out of `packages/opencode`
+
+Rules:
+
+- do not start this while `packages/server` still depends on `packages/opencode`
+- do not mix this with route migration PRs
+
+Done means:
+
+- `packages/server` can be embedded in another Node app
+- `packages/cli` can depend on `packages/server`
+- host logic no longer lives in `packages/opencode`
+
+## PR sizing rule
+
+Every migration PR should satisfy all of these:
+
+- one route group or one to two endpoints
+- no unrelated service refactor
+- no auth redesign
+- no middleware redesign
+- OpenAPI updated
+- at least one route test or spec test added or updated
+
+## Done means for a migrated route group
+
+A route group migration is complete only when:
+
+1. the `HttpApi` contract lives in `packages/server`
+2. handler implementation lives in `packages/server`
+3. the route is mounted from the current host in `packages/opencode`
+4. the route appears in merged OpenAPI
+5. request and response schemas are Effect Schema-first or clearly temporary placeholders
+6. existing behavior remains unchanged
+7. the route has straightforward test coverage
+
+## Validation expectations
+
+For package-split PRs, validate the smallest useful thing.
+
+Typical validation for the first waves:
+
+- `bun typecheck` in the touched package directory or directories
+- the relevant route test, especially `test/server/question-httpapi.test.ts`
+- merged OpenAPI coverage if the PR touches spec generation
+
+Do not run tests from repo root.
+
+## Main risks
+
+### Package cycle
+
+This is the biggest risk.
+
+Bad state:
+
+- `packages/server` imports services or runtime from `packages/opencode`
+- `packages/opencode` imports route definitions or handlers from `packages/server`
+
+Avoid by:
+
+- keeping phase-1 `packages/server` free of `packages/opencode` imports
+- using factories and host-provided wiring instead of direct service imports
+
+### Spec drift
+
+During the transition there are two route-definition sources.
+
+Avoid by:
+
+- one merged spec
+- collision checks
+- explicit `operationId`s
+- merged OpenAPI tests
+
+### Middleware mismatch
+
+Current auth, compression, CORS, and instance selection are Hono-centered.
+
+Avoid by:
+
+- leaving them where they are during the first wave
+- not trying to solve `HttpApiMiddleware.Service` globally in the package-split PRs
+
+### Core lag
+
+`packages/core` will not be ready everywhere.
+
+Avoid by:
+
+- allowing small transport-local placeholder schemas where necessary
+- keeping those placeholders clearly temporary
+- not blocking the server extraction on full schema movement
+
+### Scope creep
+
+The first vertical slice is easy to overload.
+
+Avoid by:
+
+- proving the package boundary first
+- not mixing package creation, route migration, host redesign, and core extraction in the same change
+
+## Non-goals for the first wave
+
+- do not replace all Hono routes at once
+- do not migrate SSE or websocket routes first
+- do not redesign auth
+- do not redesign instance lookup
+- do not wait for full `packages/core` before starting `packages/server`
+- do not change SDK generation to consume multiple specs
+
+## Checklist
+
+- [x] create `packages/server`
+- [x] add package-level exports for contract and OpenAPI
+- [ ] extract `question` contract into `packages/server`
+- [ ] extract `question` handler factory into `packages/server`
+- [ ] mount `question` from `packages/opencode`
+- [ ] merge legacy and contract OpenAPI into one document
+- [ ] add merged-spec coverage
+- [ ] migrate `GET /provider/auth`
+- [ ] migrate `GET /config/providers`
+- [ ] migrate small read-only instance routes one or two at a time
+- [ ] move host ownership into `packages/server` only after `packages/core` is ready enough
+- [ ] split `packages/cli` after server and core boundaries are stable
+
+## Rule of thumb
+
+The fastest correct path is:
+
+1. establish `packages/server` as the contract-first boundary
+2. keep `packages/opencode` as the temporary host
+3. migrate a few safe JSON routes
+4. keep one merged OpenAPI document
+5. move actual host ownership only after `packages/core` can support it cleanly
+
+If a proposed PR would make `packages/server` import from `packages/opencode`, stop and restructure the boundary first.
