GitHub Copilot SDK embeds the Copilot CLI agent runtime in applications. The current README marks the SDK generally available; ASE has not established its first GA date.

Availability
Generally available. SDK GA per current README. The separate Microsoft Copilot harness in Foundry was announced in public preview October 28; hosted-agent resilience GA does not make that harness GA.
How to use it
Library / CLI. TypeScript/Node.js, Python, .NET, Go, Java and Rust clients. Node.js, Python and .NET bundle the CLI; Go, Java and Rust need manual CLI setup or supported language-specific bundling.
Processing and data
Local and cloud options. The SDK talks to a CLI server over JSON-RPC; model and connected-tool processing depends on configuration. Local SDK execution does not establish offline inference. Scope tools and permissions before enabling actions.
Costs and limits
MIT SDK; Copilot allowances or BYOK/provider costs
Outputs
Programmatic agent sessions, tool calls and file/code edits in your own application. Distinct from the GitHub Copilot end-user product and Strands' harness-sdk.

Standard use requires Copilot access, including a limited Free tier; supported bring-your-own-key routes use provider credentials instead. Prompts consume allowances or provider usage. MIT covers SDK code, not unlimited models, tools or hosting. No installation or runtime test was performed.

Publisher documentation was reviewed. ASE has not independently tested this workflow, its outputs, billing, privacy controls or accessibility.

Best for

Developers embedding configurable agent sessions and tool workflows into an application.

Avoid if

You want a ready-made end-user assistant or assume MIT code includes unlimited model and tool usage.

About GitHub Copilot SDK

GitHub Copilot SDK provides language clients for Copilot's CLI agent runtime. The SDK is GA and MIT-licensed, while Copilot allowances, supported BYOK model usage, tools and infrastructure have separate requirements and costs. CLI bundling differs by language. It is separate from the end-user GitHub Copilot product, Strands harness-sdk and the Foundry-managed Copilot harness preview.
