description: Use when the user says sample skill, skill demo, or asks how an opencode SKILL.md should be structured; demonstrates a tiny project-local skill with practical assistant workflow guidance.
---
# Sample Skill
This is a minimal project-local opencode skill. It exists as a reference for how a skill is structured and as a tiny reusable workflow the assistant can load when the user asks for a skill example.
## When To Use
- Use when the user asks for a sample skill or skill template.
- Use when demonstrating the required `SKILL.md` frontmatter and body format.
- Do not use for unrelated coding tasks just because a skill exists.
## Workflow
- Confirm the specific outcome the user wants if the request is ambiguous.
- Inspect the relevant files before changing anything.
- Make the smallest correct change.
- Verify the result with a focused read, typecheck, test, or other lightweight check when available.
- Summarize the changed files and any required restart or reload step.
## Example Response Style
When this skill is relevant, keep responses direct and actionable:
```text
I created a project-local skill at .opencode/skills/sample-skill/SKILL.md.
Restart opencode for the new skill to be discovered by future sessions.
```

## V2 Session Core
- Keep durable events minimal: record irreducible new facts and do not repeat state derivable by folding the ordered aggregate history. Enrich projections and read models with previous or derived state when consumers need self-contained views.
- Keep durable prompt admission separate from model execution. `SessionV2.prompt(...)` admits one durable `session_input` row before scheduling advisory `SessionExecution.wake(sessionID)` unless `resume: false` requests admit-only behavior. The serialized runner promotes admitted inputs into visible user messages at safe boundaries.
- Reusing a Session ID adopts the existing Session. Reusing a prompt message ID reconciles an exact retry only when Session, prompt, and delivery mode match; conflicting reuse fails. Historical projected prompts lazily synthesize promoted inbox records during exact retry.
- Keep `SessionExecution` process-global and Session-ID based. Its local implementation owns the process-local Session coordinator and discovers placement through `SessionStore` plus `LocationServiceMap.get(session.location)` only when a drain starts; no layer should take a Session ID. V2 interruption targets the active process-local ownership chain for that Session; idle or missing interruption is a no-op.
- Keep `SessionRunner`, model resolution, tool registry, permissions, and filesystem Location-scoped. Omitted `Location.workspaceID` means implicit-local placement; explicit workspace identity remains reserved for future placement semantics.
- Preserve one explicit `llm.stream(request)` call per step and reload projected history before durable continuation. Do not bridge through legacy `SessionPrompt.loop(...)` or delegate orchestration to an in-memory tool loop.
- Keep local Session drains process-local until clustering is implemented. `SessionRunCoordinator` joins explicit same-Session resumes, coalesces prompt wakeups, and allows different Sessions to run concurrently. Advisory wakes drain eligible durable inbox rows only; post-crash continuation recovery requires a separate explicit design before it may retry provider work. A drain has no durable identity or transcript boundary.
- Keep delivery vocabulary explicit. Prompts steer by default and promote at the next safe step boundary while the current drain requires continuation. An explicit `queue` input remains pending until the Session would otherwise become idle; promote one queued input at that boundary, then reevaluate continuation before promoting another. Promoting any new user input resets the selected agent's step allowance; a batch of steers resets it once.
- One step is one logical LLM call; its durable record covers only the model-visible span. Do not write "provider turn", and do not use bare "turn" for a single call: "turn" is reserved for the future assistant-turn unit containing all steps from prompt promotion until the session would go idle.
- Preserve one explicit `llm.stream(request)` call per provider turn and reload projected history before durable continuation. Do not bridge through legacy `SessionPrompt.loop(...)` or delegate orchestration to an in-memory tool loop.
- Keep local Session drains process-local until clustering is implemented. `SessionRunCoordinator` joins explicit same-Session resumes, coalesces prompt wakeups, and allows different Sessions to run concurrently. Advisory wakes drain eligible durable inbox rows only; post-crash activity recovery requires a separate explicit design before it may retry provider work.
- Keep delivery vocabulary explicit. Prompts steer by default and coalesce into the active activity at the next safe provider-turn boundary. Explicit `queue` inputs open FIFO future activities one at a time after the active activity settles.
- Keep EventV2 replay owner claims separate from clustered Session execution ownership.
- Keep the Instructions algebra and built-ins in `src/instructions`; keep instruction producers with their observed domains, and keep Session History selection plus `InstructionCheckpoint` and `InstructionEntry` persistence Session-owned. `InstructionDiscovery` observes ambient global and upward-project instructions. The runner composes built-ins, discovery, guidance, and entries explicitly in `loadInstructions`; there is no instruction registry.
- The durable `Instructions.Applied` record is what the model was last told, per instruction source. Reconciliation narrates drift through `session.instructions.updated` and never rewrites the baseline; only completed compaction rebaselines, while Session movement or committed revert resets the `InstructionCheckpoint`. Unavailable sources keep the model's prior belief, blocking only a Session's first instruction baseline.
- Keep the System Context algebra, registry, and built-ins in `src/system-context`; keep Context Source producers with their observed domains, and keep Session History selection plus Context Epoch persistence Session-owned.

## Language
**Model Context**:
The complete model-visible input assembled for one **Step**, including system instructions, **Session History**, tool definitions, and step-local additions. **Instructions** are one component of Model Context, not a synonym for it.
_Avoid_: System Context
**Instructions**:
The opaque algebra of independently refreshable typed instruction sources that render the durable instruction baseline and chronological updates shown to the model.
_Avoid_: Model Context, System Context
**System Context**:
The structured collection of contextual facts presented to the model as initial instructions and chronological updates.
_Avoid_: System prompt
**Session History**:
The projected chronological conversation selected for a **Step** after applying the active compaction and **InstructionCheckpoint** baseline cutoffs.
The projected chronological conversation selected for a provider turn after applying the active compaction and **Context Epoch** cutoffs.
_Avoid_: Session Context
**Instruction Source**:
One independently observed typed value within **Instructions**, represented by a stable namespaced key, JSON codec, loader, pure baseline/update renderers, and an optional removal renderer.
**Context Source**:
One independently observed typed value within the **System Context**, represented by a stable key, JSON codec, infallible loader, pure baseline/update renderers, and an optional removal renderer for dynamic sources.
_Avoid_: Prompt fragment
**InstructionEntry**:
One API-managed, durable, per-Session instruction value. Its slash-free client key maps to the `api/<key>` **Instruction Source** key. Entries deliberately render to the model as mechanism-neutral `<context>` blocks: the model sees session context, not how it was attached.
**System Context Registry**:
The Location-scoped registry of ordered, scoped producers that contribute to the current **System Context**.
**InstructionDiscovery**:
The Location-scoped service that observes ambient global and upward-project `AGENTS.md` files as one ordered aggregate **Instruction Source**.
**Mid-Conversation System Message**:
A durable chronological instruction that tells the model the newly effective state of a changed **Context Source**.
_Avoid_: System update, system notification, raw text diff
**InstructionCheckpoint**:
The Session-owned durable instruction baseline, baseline sequence, and `Instructions.Applied` record used to prepare later Steps.
**Context Epoch**:
The span during which one effective agent's initially rendered **System Context** remains immutable, ending at compaction or another baseline-replacing transition.
**Instruction Update**:
A durable chronological System message published as `session.instructions.updated` that tells the model the newly effective state of one or more changed **Instruction Sources**.
_Avoid_: System notification, raw text diff
**Instruction Baseline**:
The exact joined instruction text stored by **InstructionCheckpoint** and sent as immutable provider-cache prefix state until completed compaction rebaselines it or Session movement or committed revert resets it.
**Baseline System Context**:
The full **System Context** rendered at the start of a **Context Epoch**.
_Avoid_: Live system prompt
**Applied Instructions**:
The overwriteable model-hidden `Instructions.Applied` record in **InstructionCheckpoint**, containing what the model was last told per **Instruction Source**.
**Context Snapshot**:
The overwriteable model-hidden JSON state used to compare each **Context Source** with the value last admitted to a provider turn.
**Unavailable Instruction Source**:
An expected temporary inability to observe an **Instruction Source** value; the runtime retains its prior effective state and emits no update, while an unavailable source blocks creation of the first complete **Instruction Baseline**.
**Unavailable Context**:
An expected temporary inability to observe a **Context Source** value; the runtime retains its prior effective state and emits no update, or omits it until first successfully loaded.
**Safe Step Boundary**:
The point during Step preparation, after prior tool settlement and before durable input promotion, where instruction changes may be admitted chronologically.
**Admitted Prompt**:
A durable user input accepted into the Session inbox but not yet included in **Session History**.
**Prompt Promotion**:
The durable transition that removes an **Admitted Prompt** from pending input and appends its user message to **Session History**.
**Step**:
One logical LLM call spanning pre-flight instruction checkpoint preparation, input promotion, request build, and compaction check; the provider stream; and tool settlement.
_Avoid_: provider turn, turn (unqualified)
**Physical Attempt**:
One actual provider request on the wire in service of a **Step**; most Steps have one Physical Attempt, while overflow-triggered compaction recovery may give one Step two.
**Assistant Turn**:
A reserved name for the not-yet-modeled unit containing all **Steps** from prompt promotion until the assistant yields the floor; do not reify it until something durable needs it.
**Settlement**:
The terminal transition for a unit of work: Step and tool settlement are durable, while drain and execution settlement are coordinator-observed.
**Execution**:
One session-scoped coordinator busy period from first wake until idle. An Execution is process-local coordination rather than a durable domain entity.
**Session Drain**:
One process-local execution span that promotes eligible input and runs required **Steps** until no immediate continuation remains. A Session Drain has no durable identity or transcript boundary.
**Safe Provider-Turn Boundary**:
The point immediately before a provider call, after durable input promotion and any required tool settlement, where context changes may be admitted chronologically.
**Model Tool Output**:
The bounded projection of a Core-executed tool result persisted in Session history and replayed to the model. A tool may shape this projection semantically, but the Tool Registry enforces the final size limit.

**Generation Controls**:
Provider-neutral sampling and output controls, partitioned from provider semantics and compatibility wire fields when model metadata enters the Catalog.
**Native Continuation Metadata**:
Opaque protocol-shaped data attached to assistant content and required to continue that content natively with a compatible model, such as a reasoning signature or provider-hosted item identifier.
**PTY Environment**:
The host-supplied environment overlay applied by the server when creating a PTY, observed for the request Location and resolved PTY working directory.
**OpenCode Client**:
The generated Promise and Effect APIs derived from the public `HttpApi`; **Embedded OpenCode** shares the Effect API through an in-memory `HttpClient` against the same router and handlers.
_Avoid_: Remote client
**SDK Contract IR**:
The runtime-neutral compiled representation of the authoritative `HttpApi`, preserving encoded and decoded type projections plus transport metadata so independent SDK emitters can choose their public value model and runtime interpreter.
**Embedded OpenCode**:
A scoped in-process host that structurally extends the **OpenCode Client**, supplies an in-memory HTTP transport, and exposes additional same-process capabilities directly.
_Avoid_: Local implementation
**Page**:
A bounded ordered result containing `items` and opaque `previous` and `next` cursor links for navigating the same query in either direction.
_Avoid_: Response envelope
## Relationships
- **Instructions** is an opaque carrier composed from zero or more **Instruction Sources**.
- **Model Context** is broader than **Instructions**. For each **Step**, the runner assembles the selected agent or provider system text, the **Instruction Baseline**, **Session History**, available tools, and step-local additions into one model request.
- **Session History** contains projected conversational messages and admitted **Instruction Updates**; the active **Instruction Baseline** remains separate provider-request state.
- The runner explicitly loads and combines instruction built-ins, **InstructionDiscovery**, selected-agent skill guidance, reference guidance, MCP guidance, and **InstructionEntry** values. There is no instruction registry.
- `Instructions.combine(...)` preserves caller order and rejects duplicate stable namespaced source keys. The runner loads its producers concurrently, then combines them in its fixed declared order.
- Each **Instruction Source** loader returns one coherent typed value or explicitly reports unavailability. `Instructions.make(...)` hides the value type so differently typed sources compose uniformly; its codec compares and stores the value, while pure renderers produce baseline, update, and optional removal text.
- `Instructions.initialize(...)` observes composed **Instructions** once and produces a complete **Instruction Baseline** with **Applied Instructions**.
- `Instructions.reconcile(...)` observes composed **Instructions** once and returns either unchanged or one combined chronological update. It never rewrites the baseline.
- `Instructions.rebaseline(...)` renders a fresh baseline after completed compaction, recalling previously applied values for sources that are temporarily unavailable.
- A changed **Instruction Source** may contribute text to one **Instruction Update** containing the newly effective state.
- An **Instruction Update** persists the exact combined rendered text sent to the model through `session.instructions.updated`.
- **Applied Instructions** advances atomically with the corresponding durable **Instruction Update**.
- **Applied Instructions** stores one codec-encoded JSON value and, for removable sources, a pre-rendered removal message per stable **Instruction Source** key.
- Changes from multiple **Instruction Sources** admitted at one safe boundary combine into one **Instruction Update**.
- Instruction changes are sampled and admitted lazily at a **Safe Step Boundary**, never pushed asynchronously when their source changes.
- At a **Safe Step Boundary**, prior tool results are already settled; instruction preparation completes before newly admitted user input promotes.
- An **Admitted Prompt** is replayable pending input, not yet model-visible **Session History**.
- **Prompt Promotion** atomically consumes the pending inbox entry and appends its model-visible user message.
- Steering prompts promote at the next **Safe Step Boundary** while the current **Session Drain** still requires continuation. Promoting any newly admitted user input resets the selected agent's step allowance; multiple prompts promoted at one boundary reset it once.
- A queued prompt does not promote while the current **Session Drain** requires continuation. The runner promotes one queued prompt when the Session would otherwise become idle, then reevaluates continuation before promoting another.
- A **Session Drain** is process-local coordination rather than a durable domain entity. Durable recovery must reason from prompts, projected history, physical attempts, and tool state rather than inventing an enclosing execution identity.
- An **Execution** contains one or more **Session Drains**; a **Session Drain** contains one reserved assistant-turn span at a time; that span contains **Steps**; and each **Step** contains one or more **Physical Attempts** plus any tool calls it requires.
- A **Step** record covers only the model-visible span from first assistant output through tool settlement; pre-flight leaves no record, and one Step settles at most one record.
- The first **Step** renders the latest complete **Instruction Baseline** and creates its **InstructionCheckpoint** without emitting a redundant **Instruction Update**; an unavailable initial source blocks the Step instead of persisting an incomplete baseline.
- Instruction preparation precedes durable input promotion on every Step so an unavailable first baseline leaves pending input untouched and later updates enter history before newly promoted input.
- Completed compaction rebaselines the **InstructionCheckpoint** from current **Instructions** and removes earlier **Instruction Updates** from active projected model history while preserving durable audit history.
- A newly composed **Instruction Source** absent from **Applied Instructions** emits its baseline rendering once at the next **Safe Step Boundary**.
- **Unavailable Instruction Source** uses stale-while-revalidate semantics and is distinct from a successfully loaded absence, which may emit removal text.
- **InstructionDiscovery** observes ambient instructions as one ordered aggregate **Instruction Source**.
- Ambient discovery reads global and upward-project `AGENTS.md` files and honors `OPENCODE_DISABLE_PROJECT_CONFIG` for project files.
- After a successful internal file or directory read, nearby `AGENTS.md` files toward the Location root are injected once per Session as durable synthetic instruction messages.
- **InstructionEntry** stores API-managed per-Session JSON values. Each entry contributes one `api/<key>` **Instruction Source**, so adding, replacing, or removing an entry is reconciled at the next **Safe Step Boundary**.
- Location-scoped instruction producers naturally re-resolve when a moved Session next runs in its destination Location.
- Moving a Session resets its **InstructionCheckpoint**, so the destination must initialize a complete baseline before another prompt can promote. Committed revert also resets the checkpoint.
- Selected-agent available-skill guidance is an **Instruction Source** composed explicitly by the runner. It lists only names and descriptions permitted for that agent; skill bodies and locations are exposed only through the permission-checked `skill` tool.
- The selected agent and model are sampled when a **Step** starts. Changes admitted after that boundary apply to the next Step and do not restart the current Step.
- An agent switch that changes selected-agent guidance produces an **Instruction Update** while preserving the current baseline.
- Local tool authorization and pending permission requests retain the effective agent of the **Step** that issued the call; a later agent switch cannot change that call's policy.
- Instruction source changes never wake idle Sessions; the next naturally scheduled **Safe Step Boundary** loads and compares current values lazily.
- Once admitted, an **Instruction Update** remains durable even if the following **Physical Attempt** fails and is replayed unchanged on retry.
- **Instruction Updates** remain durable Session-message history; normal user-facing transcript surfaces may hide them.
- The date **Instruction Source** initially preserves host-local calendar-date behavior; a configured user timezone may replace that default later.
- An **Instruction Baseline** is stored durably and reused verbatim across process restarts until rebaseline or reset.
- An **Instruction Baseline** durably preserves the exact joined text used for its part of the active provider-cache prefix.
- A model/provider switch preserves the current **InstructionCheckpoint** and chronological conversation history; the new selection applies to the next **Step**.
- **Native Continuation Metadata** remains in durable history. Step projection includes it only for a successful exact originating provider/model match; failed Steps and incompatible models omit opaque metadata, while non-empty visible reasoning lowers to ordinary assistant text after a model switch. This conservative relation may widen only when recorded provider tests establish compatibility.
- A **System Context** is an opaque carrier composed from zero or more **Context Sources**.
- **Session History** contains projected conversational messages and admitted **Mid-Conversation System Messages**; the active **Baseline System Context** remains separate provider-request state.
- The **System Context Registry** uses stable-keyed scoped contributions to assemble the current **System Context**; contributor removal naturally removes its sources at the next **Safe Provider-Turn Boundary**.
- A changed **Context Source** may produce one **Mid-Conversation System Message** containing its newly effective state.
- A **Mid-Conversation System Message** persists the exact combined rendered text sent to the model.
- The current **Context Snapshot** advances atomically with the corresponding durable **Mid-Conversation System Message**.
- A **Context Snapshot** stores one codec-encoded JSON value and, for removable dynamic sources, a pre-rendered removal message per stable **Context Source** key.
- Changes from multiple **Context Sources** admitted at one safe boundary combine into one **Mid-Conversation System Message**.
- Context changes are sampled and admitted lazily at a **Safe Provider-Turn Boundary**, never pushed asynchronously when their source changes.
- At a **Safe Provider-Turn Boundary**, newly promoted user input or settled tool results precede any combined **Mid-Conversation System Message**.
- The first provider turn renders the latest complete **Baseline System Context** and initializes its **Context Snapshot** without emitting a redundant **Mid-Conversation System Message**; unavailable initial context blocks the turn instead of persisting an incomplete baseline.
- Initial **System Context** preparation precedes the first durable input promotion so an unavailable baseline leaves that input pending and retryable; ordinary reconciliation remains after promotion.
- Compaction starts a new **Context Epoch** with a freshly rendered **Baseline System Context** and **Context Snapshot**; prior **Mid-Conversation System Messages** remain durable audit history but leave projected model history.
- A newly registered core or plugin-defined **Context Source** absent from the current snapshot emits its baseline rendering once at the next **Safe Provider-Turn Boundary**.
- **Context Source** keys are stable and namespaced; duplicate keys fail composition. `SystemContext.combine(...)` preserves caller order; the **System Context Registry** evaluates producers concurrently and combines them in stable contribution-key order so rendered context remains deterministic.
- Each **Context Source** loader returns one coherent typed value. `SystemContext.make(...)` hides that value type so differently typed sources compose uniformly. Its codec compares and stores that value; its pure renderers produce model-visible baseline, update, and removal text only when needed.
- `SystemContext.initialize(...)` observes a composed **System Context** once and produces a fresh **Baseline System Context** with its **Context Snapshot**.
- `SystemContext.reconcile(...)` observes a composed **System Context** once and returns exactly one next action: unchanged, updated, replacement ready, or replacement blocked.
- `SystemContext.replace(...)` represents an explicit baseline-replacing transition such as compaction or model/provider switch; it either produces a fresh generation or reports that replacement is blocked by unavailable admitted context.
- Context Epoch preparation retries until stable after optimistic revision mismatches so concurrent replacement requests cannot terminate an otherwise valid safe-boundary run.
- **Unavailable Context** uses stale-while-revalidate semantics and is distinct from a successfully loaded absence, which may emit removal text.
- Ordinary **Context Source** loaders return values directly; loaders that intentionally use stale-while-revalidate may explicitly return **Unavailable Context**.
- Nested project instruction discovery after successful reads remains a follow-up; when implemented, discovered instructions must be admitted durably at the next **Safe Provider-Turn Boundary**.
- Location-scoped services naturally re-resolve effective context when a moved session next runs in its destination location.
- Moving a Session clears its active **Context Epoch**, so the destination must initialize a complete baseline before another prompt can promote.
- Context Epoch initialization is fenced against the authoritative Session Location, so an old-Location runner cannot recreate source context after a concurrent move.
- Instruction discovery, source identity, persistence, and file loading belong to the instruction service; the **System Context** abstraction only composes effectful producers and renders loaded values.
- The first instruction-service slice observes global and upward project `AGENTS.md` files as one ordered aggregate **Context Source** at each **Safe Provider-Turn Boundary**.
- Built-in and instruction context producers register through the **System Context Registry** with stable contribution keys. Plugin-defined context registration and hot-reload lifecycle remain a follow-up built on the same scoped registry seam.
- Selected-agent available-skill guidance is a **Context Source** composed with Location-wide registry sources immediately before Context Epoch admission. It lists only names and descriptions permitted for that agent; skill bodies and locations are exposed only through the permission-checked `skill` tool.
- Switching the selected agent requests **Context Epoch** replacement. A switch admitted after the current **Safe Provider-Turn Boundary** applies to the next provider turn while leaving the already-prepared baseline durable. Epoch creation is fenced against the authoritative effective agent, and retries re-observe the current agent.
- A cross-agent replacement must complete before another provider turn; unavailable admitted context blocks that replacement instead of exposing the previous agent's privileged baseline.
- Local tool authorization and pending permission requests retain the effective agent of the provider turn that issued the call; a later agent switch cannot change that call's policy.
- Context source changes never wake idle sessions; the next naturally scheduled **Safe Provider-Turn Boundary** loads and compares current values lazily.
- Once admitted, a **Mid-Conversation System Message** remains durable even if the following provider attempt fails and is replayed unchanged on retry.
- **Mid-Conversation System Messages** remain durable Session-message history; normal user-facing transcript surfaces may hide them.
- The date **Context Source** initially preserves host-local calendar-date behavior; a configured user timezone may replace that default later.
- A **Context Epoch** begins with one immutable **Baseline System Context**.
- A **Context Epoch** durably records the effective agent that owns its **Baseline System Context**.
- A **Baseline System Context** is stored durably and reused verbatim across process restarts within its **Context Epoch**.
- A **Baseline System Context** durably preserves the exact joined text used for the active provider-cache prefix.
- Compaction or a model/provider switch starts a new **Context Epoch** because the baseline can be replaced without preserving the prior provider cache.
- A model/provider switch always starts a new **Context Epoch** while preserving chronological conversation history.
- **Model Request Options** remain provider-semantic through Catalog resolution. The Session runner maps them into the LLM package's provider-option namespace; the selected protocol adapter alone owns provider wire encoding.
- **Generation Controls**, protocol-semantic **Model Request Options**, and compatibility request body fields are separate Catalog domains. A shared ingestion adapter partitions legacy and models.dev AI-SDK-shaped options before routing.
- The **PTY Environment** is a server concern rather than a Core PTY concern. PTY creation merges caller values, then the host overlay, then Core-forced terminal invariants such as `TERM` and `OPENCODE_TERMINAL`.
- Networked and **Embedded OpenCode** use the same **OpenCode Client** and preserve the full HTTP encoding, routing, middleware, and decoding boundary; only the `HttpClient` transport differs.
- The Effect-native network constructor obtains `HttpClient.HttpClient` from its environment so callers own transport selection, recording, tracing, retries, and tests. Convenience runtimes may provide a fetch transport separately.
- Creating **Embedded OpenCode** is scoped. Closing its owning Scope releases the in-process server resources, database resources, registrations, and fibers.
- **Embedded OpenCode** exposes shared client capabilities and embedded-only capabilities on one object; consumers do not navigate through a nested `.client` property.
- The beta **OpenCode Client** currently uses plural consumer-facing capability groups such as `sessions`; whether the stable Session namespace should instead be singular `session` must be settled before stabilization. Internal server identifiers do not implicitly define public client names.
- Server's concrete `HttpApi` is authoritative for shared **OpenCode Client** capabilities. Codegen compiles its Session group directly; the Effect runtime uses an equivalent Protocol-only projection so generated artifacts remain independent of Core and Server.
- SDK generation reflects the public `HttpApi` once into an **SDK Contract IR**. Promise and Effect emitters share endpoint structure and transport metadata without being required to expose identical public values: an emitter may select encoded wire types, decoded domain types, compile-time brands, runtime validation, and its own execution abstraction independently.
- The first Effect emitter is the rich projection: it exposes decoded Effect-native values, preserves brands and schema transformations, performs runtime schema decoding, and delegates transport interpretation to `HttpApiClient`. Lighter wire-shaped Effect output remains possible through another emitter policy rather than constraining the shared IR.
- The rich Effect emitter regenerates private executable schemas when the **SDK Contract IR** proves that their transport semantics can be reproduced exactly. Contracts with authoritative custom transformations use the import-based Effect emitter against a Protocol-only client projection whose generated transport output is tested against Server's concrete API; the Promise emitter still derives zero-Effect structural wire types from the same IR.
- `@opencode-ai/protocol` owns Session endpoint construction and middleware placement. Server supplies concrete middleware keys to produce the authoritative build-time API; the client projection supplies transport-only keys without importing Core or Server at runtime.
- The first Promise emitter targets the same clean domain-oriented method organization rather than Hey API source compatibility. It returns unwrapped values directly, rejects declared and infrastructure failures, and begins with minimal client-level transport configuration; result wrappers, interceptors, and legacy generated signatures are outside the initial surface.
- The first Promise emitter parses response syntax and trusts its generated structural types; it does not perform runtime structural validation. Malformed payload syntax fails, while a syntactically valid shape mismatch is not detected at the SDK boundary. Standalone validator generation remains an optional future emitter policy.
- Declared Promise-client failures retain their tagged structural wire values and have generated type guards. Consumers do not depend on generated `Error` subclass identity, preserving discrimination across package copies and realms while remaining structurally aligned with Effect domain errors.
- Promise-client infrastructure failures use one generated `ClientError` class with a structured reason such as transport failure, unexpected status, unsupported content type, or malformed response. Promise methods reject with either a tagged declared domain failure or `ClientError`, matching the Effect client's conceptual domain/infrastructure error division.
- Promise methods accept a separate optional per-call transport-options argument containing `AbortSignal` and header overrides. Cancellation and transport metadata do not enter the domain input object; broader interceptor and response-mode APIs remain deferred.
- Promise streaming methods return a lazy `AsyncIterable` directly rather than a Promise-wrapped stream object. Iteration opens the connection, `AbortSignal` cancels it, and ending iteration closes the underlying request; the Effect emitter analogously returns `Stream` directly.
- Promise SSE connection establishment, declared HTTP failures, and infrastructure failures occur during `AsyncIterable` iteration, beginning with its first `next()` call, rather than during synchronous method construction.
- Neither generated streaming runtime automatically reconnects after disconnection. Promise `AsyncIterable` and Effect `Stream` fail explicitly; live consumers refresh and resubscribe, while durable sequence-based resume remains explicit composition above the generated client.
- Promise client construction is synchronous and network-free. It requires `baseUrl`, defaults to `globalThis.fetch`, accepts client-level headers, and merges them with per-call header overrides.
- Effect client construction accepts an explicit `baseUrl` and obtains `HttpClient.HttpClient` from the Effect environment. It does not install fetch or duplicate per-call transport policy; callers transform/provide the client for headers, tracing, retries, recording, and tests, while fiber interruption owns cancellation.
- Promise and Effect emitters each own their generated public type modules. The **SDK Contract IR**, not a physically shared generated type package, is the common source; this permits zero-Effect wire types and rich decoded Effect types to evolve independently.
- Promise and Effect network clients ship from `@opencode-ai/client` behind isolated root and `/effect` exports. The root has no runtime path to Effect; `/effect` imports only Effect, Schema, and Protocol.
- The Effect-native scoped host belongs to `@opencode-ai/sdk-next`, which will assume the existing `@opencode-ai/sdk` name after legacy consumers migrate. Client remains network-only and SDK depends one-way on Client.
- SDK executes Server's assembled `HttpRouter` in memory. It opens no listener and performs no network I/O, while preserving Server routing, middleware, codecs, handlers, and errors.
- The Effect Client and SDK re-export their decoded datatype facade from Schema so callers do not depend on internal package locations or Core's versioned names.
- A capability intended for both networked and **Embedded OpenCode** belongs in the authoritative public `HttpApi`; embedded-only same-process capabilities extend **Embedded OpenCode** separately.
- `sessions.events({ sessionID, after })` is a public durable Session event stream. It verifies the Session, replays durable events after the optional aggregate sequence, continues with newly committed durable events, excludes live-only fragments, and is transported as SSE in both networked and embedded modes.
- `events.subscribe()` is a distinct public instance-wide live stream for Session and non-Session activity. It has no replay guarantee and includes connection, heartbeat, and instance-disposal lifecycle events; consumers recover from disconnection by refreshing authoritative state.
- A Session ID is not an optional filter on `events.subscribe()`: instance-wide live events and durable Session events have different schemas, replay guarantees, cursors, lifecycle events, and failure behavior.
- The initial common OpenCode Client does not expose server-global event aggregation. `events.subscribe()` is bounded to the connected OpenCode instance or workspace; any future cross-instance administrative stream requires a separately designed API.
- `events.subscribe()` does not automatically reconnect after transport loss. The live-only stream fails with `ClientError`; consumers refresh authoritative state before explicitly opening a new subscription because events missed during disconnection cannot be replayed.
- `sessions.events({ sessionID, after })` returns the generated HTTP client's cold durable event stream and does not build reconnection policy into the endpoint or client constructor. Transport loss fails the stream with `ClientError`. Callers may compose an explicit resuming stream above it by retaining the last observed durable sequence and opening a new subscription with `after`; any reusable resume helper remains a separate API design question.
- The stable `sessions.list(...)` design returns a **Page** in both networked and **Embedded OpenCode**; embedded execution does not define a separate unbounded array-returning list operation. The beta client currently preserves the existing HTTP `{ data, cursor }` envelope until emitter-level Page projection is implemented.
- Session list cursors are opaque branded values carrying continuation query and ordering state. Consumers pass them back unchanged and do not inspect storage anchors or encoded filter fields.
- A Session list continuation accepts only its opaque cursor. Scope, filters, ordering, and page size are fixed by the initial query and carried by that cursor.
- `sessions.messages(...)` returns a **Page** and uses the same cursor discipline as `sessions.list(...)`: the initial request supplies `sessionID`, ordering, and page size; continuation supplies `sessionID` plus only an opaque branded message cursor carrying ordering, page size, direction, and message anchor. Using a cursor with another Session is invalid.
- `sessions.message({ sessionID, messageID })` is a required resource lookup. An unknown Session fails with `SessionNotFoundError`; a known Session with an absent or differently owned message fails with `MessageNotFoundError` without disclosing cross-Session ownership. Absence is not represented as `undefined` across the public HTTP boundary.
- `sessions.interrupt({ sessionID })` first verifies that the durable Session exists, failing with `SessionNotFoundError` otherwise. For a known Session, interruption is idempotent: idle, already-settled, or locally unowned execution is a no-op.
- `sessions.active()` snapshots the current process's foreground Session drain registry as a record of Session IDs to `{ type: "running" }`. Missing IDs are inactive; background subagents and tasks do not make their parent Session active, and process restart clears the registry.
- `sessions.context({ sessionID })` preserves the existing message-only operation. It returns projected **Session History**; it does not include or represent the complete **Model Context**, whose system text, **Instruction Baseline**, tools, and step-local additions remain separate.
- **Open question**: Should a future, separately named operation expose complete **Model Context**, including the instruction baseline, applied instruction metadata, tools, and step-local additions?
- `sessions.prompt(...)` exposes `resume?: boolean`. Omitting it preserves durable admission followed by an advisory execution wake; `resume: false` requests durable admit-only behavior.
- The public operation remains `sessions.prompt(...)`; `SessionInput.admit` is the internal primitive, while the public `Admission` result and `resume` option express its durable admission semantics.
- `sessions.create(...)` accepts an optional `location`. Omission resolves through the connected OpenCode instance's default or current location; an explicit value selects a known location. Networked and embedded transports use the same handler semantics.
- `sessions.switchAgent({ sessionID, agent })` is part of the common client alongside `sessions.switchModel(...)`. It affects subsequent Session activity and fails with `SessionNotFoundError` for an unknown Session.
- The **Embedded OpenCode** Layer delegates to the same scoped creation path; it does not define a second implementation.
- A **PTY Environment** adapter observes plugins in the request Location while passing the resolved PTY working directory to the hook; standalone servers use an empty adapter.
- An **Instruction Update** lowers to the provider's native chronological instruction role when supported and to a wrapped chronological fallback otherwise.
- When the aggregate discovered instruction set changes, its **Instruction Update** includes the complete current ordered set and supersedes the prior aggregate value; when no discovered instructions remain, the message states that previously loaded instructions no longer apply.
- A **Mid-Conversation System Message** lowers to the provider's native chronological instruction role when supported and to a wrapped chronological fallback otherwise.
- When the effective aggregate instruction set changes, its **Mid-Conversation System Message** includes the complete current ordered set and supersedes the prior aggregate value; when no ambient instructions remain, the message states that previously loaded instructions no longer apply.
- Ambient project instruction discovery honors `OPENCODE_DISABLE_PROJECT_CONFIG`; global instructions remain eligible.
- Oversized textual **Model Tool Output** retains a bounded preview in Session history while its complete text moves to managed tool-output storage. Arbitrary structured-result size is a separate concern.
- One tool settlement receives one aggregate textual limit, using the configured maximum lines or UTF-8 bytes, whichever is reached first. The limit is provider-independent; token pressure belongs to context assembly and compaction.
@@ -218,28 +119,11 @@ _Avoid_: Response envelope
- **Managed Tool Output Files** use globally unique names in one shared flat directory. Their absolute paths are readable and searchable by ordinary tools; other absolute paths remain outside Location-scoped filesystem authority.
- Provider-executed tool results remain provider-native transcript facts outside generic Tool Registry bounding. Their context control requires provider-aware pruning or compaction because some providers require exact structured round-trip payloads.
## Client contract architecture
Semantic values that mean the same thing internally and publicly live in the lightweight Schema leaf. Core consumes Schema for domain behavior; Protocol composes Schema values into paths, payloads, envelopes, errors, cursors, and streams; Server imports both, hosts Protocol's exact groups, and owns protocol/domain adaptation. The root Promise client remains zero-Effect, `/effect` depends on Effect plus Schema and Protocol, and `@opencode-ai/sdk-next` composes the scoped in-process host above Client, Core, and Server.
Shared public records are plain objects declared with `Schema.Struct`. A same-name inferred interface gives object records readable TypeScript signatures without constructors, prototypes, or nominal identity; unions retain explicit type aliases.
Before stabilizing the client API:
- Keep additional public schemas in Schema and additional network groups in Protocol; neither package may transitively load databases, Drizzle, Session execution, providers, watchers, native modules, or WASM.
- Keep concrete Location middleware keys in Server while Protocol owns their placement. Client projections may supply transport-only keys, but must prove generated equivalence with Server's concrete API.
- Project the existing list response envelope to the stable client **Page** shape and enforce separate initial-query and cursor-continuation inputs without changing the hosted V2 wire contract.
- Settle the stable consumer namespace (`session` versus the current beta `sessions`) and use an explicit codegen annotation if the consumer name should differ from the server group identifier.
- Preserve V2 route paths, operation IDs, codecs, errors, middleware behavior, and OpenAPI output while making this change.
- Preserve browser-safe `@opencode-ai/client` and `@opencode-ai/client/effect` bundles through import-boundary tests.
- Define embedded-host placement before supporting multiple hosts over one database. Hosts that share durable Session storage must also share process-local Session execution coordination, or each host must receive isolated storage explicitly.
- Keep an embedded request scope alive until any streamed response body finishes. The initial non-streaming Session surface does not exercise this lifetime boundary; Session and instance event streams must do so before joining the embedded client.
## Example dialogue
> **Dev:** "The date changed while the session was active. Should the **Instruction Update** say what the old date was?"
> **Domain expert:** "No. Emit the newly effective date so the agent can act on the current instructions."

## Flagged ambiguities
- Legacy `experimental.chat.system.transform` can mutate assembled system text arbitrarily, but V2 plugins do not yet expose an equivalent hook. Decide separately whether to port it, model dynamic uses as explicit **Instruction Sources**, or narrow its semantics.
- Legacy `experimental.chat.system.transform` can mutate the assembled baseline system prompt arbitrarily, but V2 plugins do not yet expose an equivalent hook. Decide separately whether to port it, replace dynamic uses with plugin-defined **Context Sources**, or narrow its semantics.

# Timeline Layout Continuity
Run from `packages/app`:
```sh
bun run test:stability
```
The suite runs a production build in one Chromium worker. Selected scenarios use deterministic 4x CPU stress after application readiness. This is a stress profile, not emulation of a specific device.
## What It Proves
The continuity probe samples DOM-derived layout and visibility state across browser render opportunities. Tests declare explicit contracts such as:
- Preserve a visible semantic anchor while the user is away from the bottom.
- Preserve end anchoring while active content grows or new content appears.
- Keep adjacent visible rows ordered without material overlap.
- Keep user-selected disclosure state through updates and virtualization.
- Avoid a sampled blank interval while one visible surface replaces another.
- Preserve logical row and control identity where local state or focus depends on it.
- Keep keyboard, wheel, and nested-scroll ownership consistent during remeasurement.
The suite exercises real browser reducer, projection, component, virtualizer, layout, focus, and interaction code. The backend and event producer are controlled fixtures.
## What It Does Not Prove
The pass/fail oracle does not inspect every compositor-presented pixel. A sample taken after `requestAnimationFrame` is a DOM/layout observation, not proof that every sampled state was displayed or that every displayed frame was sampled.
The suite does not provide complete coverage for:
- Compositor-only or raster-only glitches.
- Color, contrast, canvas, WebGL, masks, irregular clips, or arbitrary occlusion.
- Physical display refresh rates, native OS scaling, or a named low-end device.
- TCP packetization, proxy buffering, or the complete real server/provider pipeline.
Playwright video, trace, screenshots, and observation JSON are diagnostic evidence. They are not pixel baselines and do not participate in normal pass/fail decisions.
For optional before/violation/after screenshots, set `OPENCODE_STABILITY_CAPTURE=1`. Capture is opt-in because compositor readback can perturb timing.
## Test Layers
- **Projection:** admitted rows, grouping, labels, and final visible states.
- **Local state:** disclosure state, identity, duplicate delivery, and virtualization restoration.
- **Interaction:** wheel, keyboard, nested scrolling, actionability, and focus behavior.
- **Layout continuity:** anchoring, adjacency, responsive reflow, and visible surface handoffs.
- **Reducer hardening:** validly shaped but intentionally reordered, duplicated, removed, or replaced events.
- **Oracle contract:** pure analyzer and browser sampler calibration tests.
Production-lifecycle fixtures should model states emitted by the current producer. Impossible or reordered sequences belong in reducer-hardening tests and must not be described as normal provider behavior.
## Diagnostics
Failures retain:
- `video.webm`
- `trace.zip`
- failure screenshot
- sampled DOM/layout trace JSON
- event markers and summarized violations
The analyzer records both unclipped layout bounds and ancestor-clipped visible intersections. Scrollbar and raw `scrollTop` changes alone do not fail continuity checks; user-visible semantic anchor movement does.
