Breaking Changes

• Agent class moved to @mariozechner/pi-agent-core: The Agent class, AgentState, and related types are no longer exported from this package. Import them from @mariozechner/pi-agent-core instead.

• Transport abstraction removed: ProviderTransport, AppTransport, AgentTransport interface, and related types have been removed. The Agent class now uses streamFn for custom streaming.

• AppMessage renamed to AgentMessage: Now imported from @mariozechner/pi-agent-core. Custom message types use declaration merging on CustomAgentMessages interface.

• UserMessageWithAttachments is now a custom message type: Has role: "user-with-attachments" instead of role: "user". Use isUserMessageWithAttachments() type guard.

• CustomMessages interface removed: Use declaration merging on CustomAgentMessages from @mariozechner/pi-agent-core instead.

• agent.appendMessage() removed: Use agent.queueMessage() instead.

• Agent event types changed: AgentInterface now handles new event types from @mariozechner/pi-agent-core: message_start, message_end, message_update, turn_start, turn_end, agent_start, agent_end.

Added

• defaultConvertToLlm: Default message transformer that handles UserMessageWithAttachments and ArtifactMessage. Apps can extend this for custom message types.

• convertAttachments: Utility to convert Attachment[] to LLM content blocks (images and extracted document text).

• isUserMessageWithAttachments / isArtifactMessage: Type guard functions for custom message types.

• createStreamFn: Creates a stream function with CORS proxy support. Reads proxy settings on each call for dynamic configuration.

• Default streamFn and getApiKey: AgentInterface now sets sensible defaults if not provided:

  • streamFn: Uses createStreamFn with proxy settings from storage
  • getApiKey: Reads from providerKeys storage

• Proxy utilities exported: applyProxyIfNeeded, shouldUseProxyForProvider, isCorsError, createStreamFn

Removed

• Agent class (moved to @mariozechner/pi-agent-core)
• ProviderTransport class
• AppTransport class
• AgentTransport interface
• AgentRunConfig type
• ProxyAssistantMessageEvent type
• test-sessions.ts example file

Migration Guide

Before (0.30.x):

import { Agent, ProviderTransport, type AppMessage } from '@mariozechner/pi-web-ui';

const agent = new Agent({
  transport: new ProviderTransport(),
  messageTransformer: (messages: AppMessage[]) => messages.filter(...)
});

After:

import { Agent, type AgentMessage } from '@mariozechner/pi-agent-core';
import { defaultConvertToLlm } from '@mariozechner/pi-web-ui';

const agent = new Agent({
  convertToLlm: (messages: AgentMessage[]) => {
    // Extend defaultConvertToLlm for custom types
    return defaultConvertToLlm(messages);
  }
});
// AgentInterface will set streamFn and getApiKey defaults automatically

Custom message types:

// Before: declaration merging on CustomMessages
declare module "@mariozechner/pi-web-ui" {
  interface CustomMessages {
    "my-message": MyMessage;
  }
}

// After: declaration merging on CustomAgentMessages
declare module "@mariozechner/pi-agent-core" {
  interface CustomAgentMessages {
    "my-message": MyMessage;
  }
}
