v0.3.181

What's changed

• Added errorCode, canUserPurchaseCredits, and hasChargeableSavedPaymentMethod fields to SDKRateLimitInfo for detecting credits-required rate limits
• Added tool_use_meta.icon_url to assistant messages, populated from MCP server directory metadata
• Fixed SDK-hosted Remote Control sessions dropping file_attachments from inbound user messages

v0.3.179

What's changed

• Added optional tool_use_meta sidecar to assistant messages with display-friendly names for tool calls, so SDK consumers can render human-readable labels instead of raw wire names
• Fixed -p mode exiting before a completed background agent's notification was delivered, causing interim text to ship as the final result
• Fixed remote (stream-json) sessions appearing busy for the entire duration of a background workflow — the turn result is now emitted at the turn boundary and the session reports idle while background tasks continue

Update

npm install @anthropic-ai/claude-agent-sdk@0.3.179
# or
yarn add @anthropic-ai/claude-agent-sdk@0.3.179

# or
bun add @anthropic-ai/claude-agent-sdk@0.3.179

v0.3.178

What's changed

• Spawn failures on an existing native binary now explain the likely libc mismatch (musl binary on a glibc host) and suggest options.pathToClaudeCodeExecutable
• Permission-denied advisory messages now carry typed denial reasons (safetyCheck, asyncAgent), enabling SDK consumers to programmatically match denial causes
• Fixed UserPromptSubmit hook block feedback not being emitted to the SDK event stream — consumers can now see why a prompt was blocked by a hook instead of a silent hang
• Remote Control workers now send a worker_shutting_down system message on graceful exit so remote clients can show why the session ended
• Fixed MCP server-level specs (mcp__server, mcp__server__*) in disallowedTools being silently ignored — they now correctly remove all tools from the named server

Update

npm install @anthropic-ai/claude-agent-sdk@0.3.178
# or

v0.3.174

What's changed
