+# V2 Core Instructions
+
+These notes describe how to work on `packages/core` during the v2 port.
+
+## Direction
+
+Move behavior out of large application services and into plugins. Core services should become small, typed containers that own state, expose simple operations, and trigger hooks where policy or integration-specific logic belongs.
+
+The target shape is:
+
+- `packages/core` contains domain schemas, typed errors, state containers, events, and plugin hook contracts.
+- Plugins implement provider-specific, config-specific, auth-specific, model-discovery, and generation behavior.
+- Services are hot-reloadable by design: updates are granular, observable, and do not require tearing down the whole process.
+- `packages/opencode` becomes thinner over time: UI, server routes, CLI, storage glue, and legacy compatibility should call the core services instead of owning domain logic directly.
+
+## Service Shape
+
+Core services should look like `Catalog`, `AccountV2`, and `AgentV2`:
+
+- define schemas and branded ids at the top of the module
+- define typed `Schema.TaggedErrorClass` errors for expected failures
+- define an `Interface` with small operations
+- expose a `Context.Service`
+- implement `layer` with private in-memory state
+- expose `defaultLayer` with explicit dependencies
+- self-export with `export * as Name from "./file"`
+
+Prefer a dumb container API:
+
+- `get`, `all`, `available`, `default`, `update`, `remove`, `activate`, or other small domain verbs
+- `update(id, draft => ...)` for registration and mutation
+- hook calls before committing mutations when plugins need to enrich, cancel, or validate changes
+- events after committing mutations when other services or frontends need to react
+
+Avoid putting application policy directly in core services unless it is a domain invariant. For example, resolving model endpoint inheritance is catalog-owned; deciding which providers to register is plugin-owned.
+
+## Plugin Hooks
+
+Plugins are the extension boundary for v2. Add hooks to `PluginV2.HookSpec` when logic should be provided by integrations instead of the container itself.
+
+Hook conventions:
+
+- hooks receive immutable input plus mutable output
+- mutable object outputs are exposed as Immer drafts
+- include `cancel: boolean` when plugins can prevent a mutation
+- trigger hooks sequentially so ordering remains deterministic
+- keep hook names domain-oriented, like `provider.update`, `model.update`, `account.activate`, `agent.generate`
+- keep hook payloads small and typed with core schemas
+
+Use hooks for:
+
+- registering providers and models
+- applying env/account/config-derived enablement
+- transforming SDK/provider options
+- implementing generated behavior such as agent generation
+- choosing defaults when the choice is policy rather than state
+
+Do not use hooks as a dumping ground for transport concerns, UI behavior, or compatibility shims.
+
+## Plugin Boot
+
+Built-in core plugins are registered by `packages/core/src/plugin/boot.ts`.
+
+When a new core service is intended to be available to plugins:
+
+- add the service to the boot layer dependency type
+- yield the service inside the layer
+- provide it to each plugin effect in `add`
+- add its default layer to `PluginBoot.defaultLayer` only when that does not create a cycle
+
+Keep boot as composition only. It should not contain provider, account, agent, or model policy itself.
+
+## Boundaries
+
+Core should not import from `packages/opencode`. If a type or concept is needed by core, move or remodel the domain shape in core first.
+
+Avoid moving legacy services over wholesale. Port the domain shape and the container API, then leave specific behavior behind hooks for plugins to implement.
+
+When porting an opencode service:
+
+- identify the state it owns
+- identify the operations callers actually need
+- identify which branches are policy or integration behavior
+- model state and operations in `packages/core`
+- add hooks for the policy/integration branches
+- keep old package code working until callers can migrate incrementally
+
+## Schemas And Types
+
+Use Effect schemas as the public contract:
+
+- branded schemas for ids
+- `Schema.Class` or `Schema.Struct` for domain data
+- `Schema.TaggedErrorClass` for expected errors
+- existing core helpers like `DeepMutable`, `withStatics`, and integer schemas where appropriate
+
+Prefer `Info` objects as the stored domain records. Add static `empty(...)` constructors when update APIs need to create records on first mutation.
+
+Keep schemas stable and explicit. Do not rely on opencode config shapes as core domain shapes unless the config shape is actually the domain model.
+
+## State And Events
+
+Keep state private to the service layer. Use immutable replacement or Effect refs when persistence/concurrency requires it.
+
+Publish events for committed domain changes, not for attempted mutations. Event names should describe domain facts, for example `catalog.model.updated`.
+
+The v2 goal is granular reconfiguration. A model update should let dependents react to that model update; it should not require global reloads.
+
+## Style
+
+Follow the local core style:
+
+- `Effect.gen(function* () { ... })` for composition
+- `Effect.fn("Domain.method")` for public service methods
+- `Effect.fnUntraced` for small internal mutation helpers
+- `yield* new ErrorClass(...)` for typed failures
+- minimal helpers unless they name a real concept
+- no `any` unless an existing plugin boundary requires it
+- no compatibility code without a concrete persisted or external-consumer need
+
+Prefer the smallest correct port. The goal is to make services easier to replace and reason about, not to recreate the old architecture in a new package.
