v0.2.0 Latest

Latest

This is a big update with a broad round of API refinements, new capabilities, and cross-SDK consistency improvements that have shipped incrementally through preview releases since v0.1.32.

Highlights

Fine-grained system prompt customization

A new "customize" mode for systemMessage lets you surgically edit individual sections of the Copilot system prompt — without replacing the entire thing. Ten sections are configurable: identity, tone, tool_efficiency, environment_context, code_change_rules, guidelines, safety, tool_instructions, custom_instructions, and last_instructions.

Each section supports four static actions (replace, remove, append, prepend) and a transform callback that receives the current rendered content and returns modified text — useful for regex mutations, conditional edits, or logging what the prompt contains. (#816)

const session = await client.createSession({
  onPermissionRequest: approveAll,
  systemMessage: {
    mode: "customize",
    sections: {
      identity: {
        action: (current) => current.replace("GitHub Copilot", "Acme Assistant"),
      },
      tone: { action: "replace", content: "Be concise and professional." },
      code_change_rules: { action: "remove" },
    },
  },
});

var session = await client.CreateSessionAsync(new SessionConfig {
    OnPermissionRequest = PermissionHandler.ApproveAll,
    SystemMessage = new SystemMessageConfig {
        Mode = SystemMessageMode.Customize,
        Sections = new Dictionary<string, SectionOverride> {
            ["identity"] = new() {
                Transform = current => Task.FromResult(current.Replace("GitHub Copilot", "Acme Assistant")),
            },
            ["tone"] = new() { Action = SectionOverrideAction.Replace, Content = "Be concise and professional." },
            ["code_change_rules"] = new() { Action = SectionOverrideAction.Remove },
        },
    },
});

OpenTelemetry support across all SDKs

All four SDK languages now support distributed tracing with the Copilot CLI. Set telemetry in your client options to configure an OTLP exporter; W3C trace context is automatically propagated on session.create, session.resume, and session.send, and restored in tool handlers so tool execution is linked to the originating trace. (#785)

const client = new CopilotClient({
  telemetry: {
    otlpEndpoint: "http://localhost:4318",
    sourceName: "my-app",
  },
});

var client = new CopilotClient(new CopilotClientOptions {
    Telemetry = new TelemetryConfig {
        OtlpEndpoint = "http://localhost:4318",
        SourceName = "my-app",
    },
});

Python: CopilotClient(SubprocessConfig(telemetry={"otlp_endpoint": "http://localhost:4318", "source_name": "my-app"}))
Go: copilot.NewClient(&copilot.ClientOptions{Telemetry: &copilot.TelemetryConfig{OTLPEndpoint: "http://localhost:4318", SourceName: "my-app"}})

Blob attachments for inline binary data

A new blob attachment type lets you send images or other binary content directly to a session without writing to disk — useful when data is already in memory (screenshots, API responses, generated images). (#731)

await session.send({
  prompt: "What's in this image?",
  attachments: [{ type: "blob", data: base64Str, mimeType: "image/png" }],
});

await session.SendAsync(new MessageOptions {
    Prompt = "What's in this image?",
    Attachments = [new UserMessageDataAttachmentsItemBlob { Data = base64Str, MimeType = "image/png" }],
});

Pre-select a custom agent at session creation

You can now specify which custom agent should be active when a session starts, eliminating the need for a separate session.rpc.agent.select() call. (#722)

const session = await client.createSession({
  customAgents: [
    { name: "researcher", prompt: "You are a research assistant." },
    { name: "editor", prompt: "You are a code editor." },
  ],
  agent: "researcher",
  onPermissionRequest: approveAll,
});

var session = await client.CreateSessionAsync(new SessionConfig {
    CustomAgents = [
        new CustomAgentConfig { Name = "researcher", Prompt = "You are a research assistant." },
        new CustomAgentConfig { Name = "editor", Prompt = "You are a code editor." },
    ],
    Agent = "researcher",
    OnPermissionRequest = PermissionHandler.ApproveAll,
});

New features

skipPermission on tool definitions — Tools can now be registered with skipPermission: true to bypass the confirmation prompt for low-risk operations like read-only queries. Available in all four SDKs. (#808)
reasoningEffort when switching models — All SDKs now accept an optional reasoningEffort parameter in setModel() for models that support it. (#712)
Custom model listing for BYOK — Applications using bring-your-own-key providers can supply onListModels in client options to override client.listModels() with their own model list. (#730)
no-result permission outcome — Permission handlers can now return "no-result" so extensions can attach to sessions without actively answering permission requests. (#802)
SessionConfig.onEvent catch-all — A new onEvent handler on session config is registered before the RPC is issued, guaranteeing that early events like session.start are never dropped. (#664)
Node.js CJS compatibility — The Node.js SDK now ships both ESM and CJS builds, fixing crashes in VS Code extensions and other tools bundled with esbuild's format: "cjs". No changes needed in consumer code. (#546)
Experimental API annotations — APIs marked experimental in the schema (agent, fleet, compaction groups) are now annotated in all four SDKs: [Experimental] in C#, /** @experimental */ in TypeScript, and comments in Python and Go. (#875)
System notifications and session log APIs — Updated to match the latest CLI runtime, adding system.notification events and a session log RPC API. (#737)

Improvements

[.NET, Go] Serialize event dispatch so handlers are invoked in registration order with no concurrent calls (#791)
[Go] Detach CLI process lifespan from the context passed to Client.Start so cancellation no longer kills the child process (#689)
[Go] Stop RPC client logging expected EOF errors (#609)
[.NET] Emit XML doc comments from schema descriptions in generated RPC code (#724)
[.NET] Use lazy property initialization in generated RPC classes (#725)
[.NET] Add DebuggerDisplay attribute to SessionEvent for easier debugging (#726)

[.NET] Replace Task.WhenAny + Task.Delay timeout pattern with .WaitAsync(TimeSpan) (#805)
[.NET] Add NuGet package icon (#688)
[Node] Don't resolve cliPath when cliUrl is already set (#787)

New RPC methods

We've added low-level RPC methods to control a lot more of what's going on in the session. These are emerging APIs that don't yet have friendly wrappers, and some may be flagged as experimental or subject to change.

session.rpc.skills.list(), .enable(name), .disable(name), .reload()
session.rpc.mcp.list(), .enable(name), .disable(name), .reload()
session.rpc.extensions.list(), .enable(name), .disable(name), .reload()
session.rpc.plugins.list()
session.rpc.ui.elicitation(...) — structured user input
session.rpc.shell.exec(command), .kill(pid)
session.log(message, level, ephemeral)

In an forthcoming update, we'll add friendlier wrappers for these.

Bug fixes

[.NET] Fix SessionEvent.ToJson() failing for events with JsonElement-backed payloads (assistant.message, tool.execution_start, etc.) (#868)
[.NET] Add fallback TypeInfoResolver for StreamJsonRpc.RequestId to fix NativeAOT compatibility (#783)
[.NET] Fix codegen for discriminated unions nested within other types (#736)
[.NET] Handle unknown session event types gracefully instead of throwing (#881)

⚠️ Breaking changes

All SDKs

autoRestart removed — The autoRestart option has been deprecated across all SDKs (it was never fully implemented). The property still exists but has no effect and will be removed in a future release. Remove any references to autoRestart from your client options. (#803)

v0.1.33-preview.4

005b780

v0.1.33-preview.4 Pre-release

Pre-release

Feature: fine-grained system prompt customization

A new "customize" mode for systemMessage lets you selectively override individual sections of the Copilot system prompt — without replacing the entire prompt. This sits between "append" (add to the end) and "replace" (replace everything). (#816)

Ten sections are configurable: identity, tone, tool_efficiency, environment_context, code_change_rules, guidelines, safety, tool_instructions, custom_instructions, and last_instructions.

Each section supports four static actions (replace, remove, append, prepend) and a transform action — a callback that receives the current rendered section content and returns the modified version, enabling regex mutations, logging, or conditional edits.

const session = await client.createSession({
  systemMessage: {
    mode: "customize",
    sections: {
      identity: {
        // transform: read current content and return modified content
        action: (current) => current.replace("GitHub Copilot", "Acme Assistant"),
      },
      tone: { action: "replace", content: "Be concise and professional." },
      code_change_rules: { action: "remove" },
    },
  },
});

var session = await client.CreateSessionAsync(new SessionOptions {
    SystemMessage = new SystemMessageOptions {
        Mode = SystemMessageMode.Customize,
        Sections = new Dictionary(string, SectionOverride) {
            ["identity"] = new() {
                Transform = current => current.Replace("GitHub Copilot", "Acme Assistant"),
            },
            ["tone"] = new() { Action = "replace", Content = "Be concise and professional." },
            ["code_change_rules"] = new() { Action = "remove" },

    Telemetry = new TelemetryConfig {
        OtlpEndpoint = "(localhost/redacted)
        SourceName = "my-app",
    },
});

A new blob attachment type lets you send images or other binary content directly to a session without writing to disk first — useful when data is already in memory (screenshots, API responses, generated images). (#731)

await session.send("What's in this image?", {
  attachments: [{ type: "blob", data: base64Str, mimeType: "image/png" }],
});

await session.SendAsync("What's in this image?", new MessageOptions {
    Attachments = [new BlobAttachment { Data = base64Str, MimeType = "image/png" }],
});

Feature: Node.js CommonJS (CJS) compatibility

The Node.js SDK now ships both ESM and CJS builds, fixing crashes in VS Code extensions and other tools bundled with esbuild's format: "cjs". No changes needed in consumer code — Node automatically selects the right format. (#546)

Feature: `reasoningEffort` when switching models

All SDKs now accept an optional reasoningEffort parameter in setModel() for models that support it. (#712)

await session.setModel("claude-sonnet-4.6", { reasoningEffort: "high" });

await session.SetModelAsync("claude-sonnet-4.6", reasoningEffort: "high");

Python: await session.set_model("claude-sonnet-4.6", reasoning_effort="high")
Go: session.SetModel(ctx, "claude-sonnet-4.6", &copilot.SetModelOptions{ReasoningEffort: "high"})

Feature: `skipPermission` flag on tool definitions

Tools can now be registered with skipPermission: true (or SkipPermission in .NET) to bypass the permission confirmation step for low-risk tools such as read-only queries. (#808)

session.defineTool("query_db", { skipPermission: true }, async (params) => {
  // read-only, no permission prompt
});

session.DefineTool("query_db", new ToolOptions { SkipPermission = true }, async (params) => {
    // read-only, no permission prompt
});

Feature: experimental API annotations

APIs marked experimental in the schema (agent, fleet, and compaction groups) are now annotated in all four SDK languages: [Experimental] in C#, /** @experimental */ in TypeScript, and comments in Python and Go. Experimental APIs will continue to evolve. (#875)

Other changes

feature: [Python] CopilotClient constructor now accepts typed config objects instead of individual keyword arguments (#793)
feature: [Python] updated CopilotSession.send() and send_and_wait() signatures for cleaner API surface (#814)
feature: [Python] add typed overloads for CopilotClient.on() event registration (#589)
improvement: [.NET, Go] serialize event dispatch so handlers are invoked in registration order with no concurrent calls (#791)
improvement: [Go] detach CLI process lifespan from the context passed to Client.Start so cancellation no longer kills the child process (#689)
improvement: [Go] LogOptions.Ephemeral changed from bool to *bool for proper three-state semantics; use copilot.Bool(true) (#827)
improvement: [Go] stop RPC client logging expected EOF errors (#609)
bugfix: [C#] fix SessionEvent.ToJson() failing for events with JsonElement-backed payloads (assistant.message, tool.execution_start, etc.) (#868)
bugfix: [.NET] add fallback TypeInfoResolver for StreamJsonRpc.RequestId to fix NativeAOT compatibility (#783)
improvement: [.NET] replace Task.WhenAny + Task.Delay timeout pattern with .WaitAsync(TimeSpan) (#805)

v0.1.33-preview.0

df59a0e

v0.1.33-preview.0 Pre-release

Pre-release

Feature: pre-select a custom agent at session creation

You can now specify which custom agent should be active when a session starts, without needing a separate session.rpc.agent.select() call. (#722)

const session = await client.createSession({
  customAgents: [
    { name: "researcher", prompt: "You are a research assistant." },
    { name: "editor", prompt: "You are a code editor." },
  ],
  agent: "researcher",  // active agent at session start
  onPermissionRequest: approveAll,
});

var session = await client.CreateSessionAsync(new SessionConfig {
    CustomAgents = [
        new CustomAgentConfig { Name = "researcher", Prompt = "You are a research assistant." },
        new CustomAgentConfig { Name = "editor", Prompt = "You are a code editor." },
    ],
    Agent = "researcher",  // active agent at session start
});

Feature: custom model listing for BYOK

Applications using bring-your-own-key providers can now supply onListModels in client options to override client.listModels() with their own model list, instead of forwarding the call to the CLI. (#730)

const client = new CopilotClient({ onListModels: () => myProviderModels });

var client = new CopilotClient(new CopilotClientOptions {
    OnListModels = () => Task.FromResult(myProviderModels)
});

Python: on_list_models=lambda: my_provider_models
Go: OnListModels: func(ctx context.Context) ([]copilot.ModelInfo, error) { return myModels, nil }

Feature: new events and APIs (system notifications, session log, extension support)

Updated to match the latest CLI runtime, adding: system.notification events, a session log RPC API, reasoningEffort changes after model switch, alreadyInUse flag on sessions, and the groundwork for extension-based integrations. (#737)

Other changes

feature: add no-result permission outcome so extensions can attach to sessions without actively answering permission requests (#802)
bugfix: fix race condition where events emitted during session creation (e.g. session.start) could be dropped; also adds OnEvent catch-all handler to SessionConfig (#664)
improvement: [C#] optional RPC params are now represented as optional C# method params for forward-compatible generated code (#733)
bugfix: [C#] fix codegen for discriminated unions nested within other types (#736)
improvement: [C#] emit XML doc comments from schema descriptions in generated RPC code (#724)
improvement: [C#] use lazy property initialization in generated RPC classes (#725)
improvement: [C#] add DebuggerDisplay attribute to SessionEvent for easier debugging (#726)
improvement: [.NET] add NuGet package icon (#688)
bugfix: [Node] don't resolve cliPath when cliUrl is already set (#787)

v0.1.31

v0.1.31

Feature: strongly-typed `PermissionRequestResultKind` for .NET and Go

Rather than comparing result.Kind against undiscoverable magic strings like "approved" or "denied-interactively-by-user", .NET and Go now provide typed constants. Node and Python already had typed unions for this; this brings full parity. (#631)

session.OnPermissionCompleted += (e) => {
    if (e.Result.Kind == PermissionRequestResultKind.Approved) { /* ... */ }
    if (e.Result.Kind == PermissionRequestResultKind.DeniedInteractivelyByUser) { /* ... */ }
};

// Go: PermissionKindApproved, PermissionKindDeniedByRules,
//     PermissionKindDeniedCouldNotRequestFromUser, PermissionKindDeniedInteractivelyByUser
if result.Kind == copilot.PermissionKindApproved { /* ... */ }

Other changes

feature: [Python] [Go] add get_last_session_id() / GetLastSessionID() for SDK-wide parity (was already available in Node and .NET) (#671)
improvement: [Python] add timeout parameter to generated RPC methods, allowing callers to override the default 30s timeout for long-running operations (#681)
bugfix: [Go] PermissionRequest fields are now properly typed (ToolName, Diff, Path, etc.) instead of a generic Extra map[string]any catch-all (#685)

v0.1.30

v0.1.30

Feature: support overriding built-in tools

Applications can now override built-in tools such as grep, edit_file, or read_file. To do this, register a custom tool with the same name and set the override flag. Without the flag, the runtime will return an error if the name clashes with a built-in. (#636)

import { defineTool } from "`@github/copilot-sdk`";

const session = await client.createSession({
  tools: [defineTool("grep", {
    overridesBuiltInTool: true,
    handler: async (params) => `CUSTOM_GREP_RESULT: \$\{params.query}`,
  })],
  onPermissionRequest: approveAll,
});

var grep = AIFunctionFactory.Create(
    ([Description("Search query")] string query) => $"CUSTOM_GREP_RESULT: {query}",
    "grep",
    "Custom grep implementation",
    new AIFunctionFactoryOptions
    {
        AdditionalProperties = new ReadOnlyDictionary(string, object?)(
            new Dictionary(string, object?) { ["is_override"] = true })
    });

Feature: simpler API for changing model mid-session

While session.rpc.model.switchTo() already worked, there is now a convenience method directly on the session object. (#621)

TypeScript: await session.setModel("gpt-4.1")
C#: await session.SetModelAsync("gpt-4.1")
Python: await session.set_model("gpt-4.1")
Go: err := session.SetModel(ctx, "gpt-4.1")

Other changes

improvement: [C#] use event delegate for thread-safe, insertion-ordered event handler dispatch (#624)
improvement: [C#] deduplicate OnDisposeCall and improve implementation (#626)
improvement: [C#] remove unnecessary SemaphoreSlim locks for handler fields (#625)
bugfix: [Python] correct PermissionHandler.approve_all type annotations (#618)
