Changelog

[Unreleased]

[6.8.0] - 2026-01-20

Changed

• Updated proxy stream processing to use utility function for reading lines

[6.2.0] - 2026-01-19

Added

• Enhanced getToolContext to receive tool call batch information including batchId, index, total count, and tool call details

[5.6.7] - 2026-01-18

Fixed

• Added proper tool result messages for tool calls that are aborted or error out
• Ensured tool_use/tool_result pairing is maintained when tool execution fails

[4.6.0] - 2026-01-12

Changed

• Modified assistant message handling to split messages around tool results for improved readability when using Cursor tools

Fixed

• Fixed tool result ordering in Cursor mode by buffering results and emitting them at the correct position within assistant messages

[4.3.0] - 2026-01-11

Added

• Added cursorExecHandlers and cursorOnToolResult options for local tool execution with cursor-based streaming
• Added emitExternalEvent method to allow external event injection into the agent state

[4.0.0] - 2026-01-10

Added

• Added popLastSteer() and popLastFollowUp() methods to remove and return the last queued message (LIFO) for dequeue operations
• thinkingBudgets option on Agent and AgentOptions to customize token budgets per thinking level
• sessionId option on Agent to forward session identifiers to LLM providers for session-based caching

Fixed

• minimal thinking level now maps to minimal reasoning effort instead of being treated as low

[3.33.0] - 2026-01-08

Fixed

• Ensured aborted assistant responses always include an error message for callers.
• Filtered thinking blocks from Cerebras request context to keep multi-turn prompts compatible.

[3.21.0] - 2026-01-06

Changed

• Switched from local @oh-my-pi/pi-ai to upstream @oh-my-pi/pi-ai package

Added

• Added sessionId option for provider caching (e.g., OpenAI Codex session-based prompt caching)
• Added sessionId getter/setter on Agent class for runtime session switching

[3.20.0] - 2026-01-06

Breaking Changes

• Replaced queueMessage/queueMode with steering + follow-up queues: use steer, setSteeringMode, and getSteeringMode for mid-run interruptions, and followUp, setFollowUpMode, and getFollowUpMode for post-turn messages
• Agent loop callbacks now use getSteeringMessages and getFollowUpMessages instead of getQueuedMessages

Added

• Added follow-up message queue support so new user messages can continue a run after the agent would otherwise stop
• Added RenderResultOptions.spinnerFrame for animated tool-result rendering

Changed

• prompt() and continue() now throw when the agent is already streaming; use steering or follow-up queues instead

[3.4.1337] - 2026-01-03

Added

• Added popMessage() method to Agent class for removing and retrieving the last message
• Added abort signal checks during response streaming for faster interruption handling

Fixed

• Fixed abort handling to properly return aborted message state when stream is interrupted mid-response

[1.341.0] - 2026-01-03

Added

• Added interruptMode option to control when queued messages interrupt tool execution.
• Implemented "immediate" mode (default) to check queue after each tool and interrupt remaining tools.
• Implemented "wait" mode to defer queue processing until the entire turn completes.
• Added getter and setter methods for interruptMode on Agent class.

[1.337.1] - 2026-01-02

Changed

• Forked to @oh-my-pi scope with unified versioning across all packages

[1.337.0] - 2026-01-02

Initial release under @oh-my-pi scope. See previous releases at badlogic/pi-mono.

[0.31.0] - 2026-01-02

Breaking Changes

• Transport abstraction removed: ProviderTransport, AppTransport, and AgentTransport interface have been removed. Use the streamFn option directly for custom streaming implementations.

• Agent options renamed:

  • transport → removed (use streamFn instead)
  • messageTransformer → convertToLlm
  • preprocessor → transformContext

• AppMessage renamed to AgentMessage: All references to AppMessage have been renamed to AgentMessage for consistency.

• CustomMessages renamed to CustomAgentMessages: The declaration merging interface has been renamed.

• UserMessageWithAttachments and Attachment types removed: Attachment handling is now the responsibility of the convertToLlm function.

• Agent loop moved from @oh-my-pi/pi-ai: The agentLoop, agentLoopContinue, and related types have moved to this package. Import from @oh-my-pi/pi-agent instead.

Added

• streamFn option on Agent for custom stream implementations. Default uses streamSimple from pi-ai.

• streamProxy() utility function for browser apps that need to proxy LLM calls through a backend server. Replaces the removed AppTransport.

• getApiKey option for dynamic API key resolution (useful for expiring OAuth tokens like GitHub Copilot).

• agentLoop() and agentLoopContinue() low-level functions for running the agent loop without the Agent class wrapper.

• New exported types: AgentLoopConfig, AgentContext, AgentTool, AgentToolResult, AgentToolUpdateCallback, StreamFn.

Changed

• Agent constructor now has all options optional (empty options use defaults).

• queueMessage() is now synchronous (no longer returns a Promise).
