Copilot SDK v0.2.1: Commands & Metadata Across All SDKs

TL;DR

• Slash commands and UI dialogs now available in Python, Go, and .NET (previously Node.js only)
• New getSessionMetadata method across all SDKs for efficient session lookup
• Breaking change in Node.js: onElicitationRequest handler signature changed to single context object

New

• Commands and UI elicitation across all SDKs — Register slash commands and drive interactive dialogs (confirm, select) from Python, Go, and .NET. Previously Node.js-only.
• session.getSessionMetadata across all SDKs — Fetch metadata for a single session by ID without listing all sessions. Returns undefined/null if not found.
• sessionFs for Node SDK — Custom storage adapter to redirect per-session storage (event logs, large files) to any backing store. Useful for serverless and custom persistence.
• Python: async context manager support — CopilotClient and CopilotSession now support async with for automatic resource cleanup.

Fixed

• Structured tool results now sent as objects instead of stringified JSON, preserving metadata across Node, Go, and Python SDKs.

Breaking Changes

• Node.js: onElicitationRequest signature — Changed from two arguments (request, invocation) to a single ElicitationContext. Update callers to use context.sessionId and context.message directly.
• Python: types import path — copilot.types module removed. Import types directly from copilot.
• Go: RPC package API — Struct names simplified; removed redundant Rpc infix (e.g., ModelRpcApi → ModelApi).
• Go: Session.SetModel signature — Now takes a pointer for optional options instead of variadic argument.

Improvements

• Python: Path handling — workspace_path now accepts any os.PathLike and returns pathlib.Path.

Update with: npm install @github/copilot-sdk@0.2.1 (Node.js), pip install github-copilot-sdk==0.2.1 (Python), or check the release page for Go and .NET packages.
