All notable changes to @cognipeer/agent-server.

[0.1.5] - 2026-03-24

Fixed

• Prevented duplication of the final text chunk in Agent SDK streams
• Made the onEvent handler phase-aware to stop duplicate SSE tool_call events: start now emits stream.tool_call, success/error emit stream.tool_result, and skipped (tool limit reached) is suppressed — previously every tool call produced two stream.tool_call events, causing duplicate rendering in the chat UI

[0.1.4] - 2026-03-06

Added

• Chat Completions and Responses API providers for OpenAI-compatible endpoints and multi-turn conversations with built-in tools
• SQLite storage provider (via better-sqlite3), with migration logic for conversations, messages, files, tasks, and task results
• Automatic conversation title generation using LLM configuration

[0.1.3] - 2026-02-25

Fixed

• Ensured message content is always stringified in PostgresStorageProvider

Changed

• Enabled code splitting in the tsup build configuration

[0.1.2] - 2026-02-25

No distinct changes — published the same day as 0.1.0, 0.1.1, and 0.1.3 during the initial release's rapid-iteration burst. Git history jumps directly from the 0.1.1 to the 0.1.3 version bump, so no separate 0.1.2 commits could be identified; the fix and build change above are the actual delta.

[0.1.1] - 2026-02-25

Added

• Full Task system: types, storage-provider implementations (in-memory, MongoDB, PostgreSQL), API endpoints, execution logic, and Swagger/OpenAPI documentation
• Task comments feature with dedicated API endpoints and Swagger documentation
• Comprehensive Task system documentation

Changed

• Preserved tool-call information in message structure — SDK agent invocation now includes optional tool_calls, tool_call_id, and name fields, correctly mapped from prior messages
• Refactored event handling to use a shared helper for extracting tool event properties, with improved error logging
• Translated README to English and clarified installation instructions
• Added repository, homepage, and bugs metadata to package.json

Fixed

• Fixed a syntax error in the base storage provider
• Fixed callback status consistency (completed instead of complete)
