Breaking changes:
- Agent class moved to @mariozechner/pi-agent-core
- Transport abstraction removed (ProviderTransport, AppTransport)
- AppMessage renamed to AgentMessage
- UserMessageWithAttachments now has role: 'user-with-attachments'
- CustomMessages interface replaced with CustomAgentMessages
- agent.appendMessage() removed (use queueMessage())
- New agent event types from pi-agent-core
Added:
- defaultConvertToLlm, convertAttachments utilities
- isUserMessageWithAttachments, isArtifactMessage type guards
- createStreamFn for CORS proxy support
- Default streamFn and getApiKey on AgentInterface
- Proxy utilities exported
README completely rewritten to reflect new architecture.
- StreamFn type now allows returning Promise
- agent-loop awaits streamFn result
- createStreamFn takes getProxyUrl callback, reads settings on each call
- createStreamFn(proxyUrl?) returns a sync streamFn that applies proxy
- Example reads proxy settings once when creating Agent
- Matches old ProviderTransport behavior
- AgentInterface composes UserMessageWithAttachments for attachments
- Updated example to use convertToLlm instead of transport/messageTransformer
- Fixed declaration merging: target pi-agent-core, add path to example tsconfig
- Fixed typo in CustomAgentMessages key (user-with-attachment -> user-with-attachments)
- customMessageTransformer properly converts UserMessageWithAttachments to content blocks
- Removed Attachment from agent package (now in web-ui/coding-agent)
- Agent.prompt now takes (text, images?: ImageContent[])
- Removed transports from web-ui (duplicate of agent package)
- Updated coding-agent to use local message types
- Updated mom package for new agent API
Remaining: Fix AgentInterface.ts to compose UserMessageWithAttachments
- Remove setApiKey, resolveApiKey, and global apiKeys Map from stream.ts
- Rename getApiKey to getApiKeyFromEnv (only checks env vars)
- Remove OAuth storage layer (storage.ts deleted)
- OAuth login/refresh functions now return credentials instead of saving
- getOAuthApiKey/refreshOAuthToken now take credentials as params
- Add test/oauth.ts helper for ai package tests
- Simplify root npm run check (single biome + tsgo pass)
- Remove redundant check scripts from most packages
- Add web-ui and coding-agent examples to biome/tsgo includes
coding-agent still has compile errors - needs refactoring for new API
Add getApiKey hook to AgentLoopConfig that resolves API keys dynamically
before each LLM call. This allows short-lived OAuth tokens (e.g. GitHub
Copilot, Anthropic OAuth) to be refreshed between turns when tool
execution takes a long time.
Previously, the API key was resolved once when ProviderTransport.run()
was called and passed as a static string to the agent loop. If the loop
ran for longer than the token lifetime (e.g. 30 minutes for Copilot),
subsequent LLM calls would fail with expired token errors.
Changes:
- Add getApiKey hook to AgentLoopConfig (packages/ai)
- Call getApiKey before each LLM call in streamAssistantResponse
- Update ProviderTransport to pass getApiKey instead of static apiKey
- Update web-ui ProviderTransport with same pattern
