* feat(ui): add Chat UI v0 — standalone LiteLLM-branded chat window Adds a full chat UI accessible from the sidebar Chat link (opens in new tab). - Standalone route at /chat (outside dashboard layout — no Navbar/Sidebar chrome) - Claude.ai-style layout: model selector top-left, LiteLLM logo center, settings top-right - Greeting with time-of-day, centered input card, suggestion chips (Write/Learn/Code/Brainstorm) - Sliding conversation history sidebar with Cmd+K search, rename, delete, date grouping - localStorage-backed conversation persistence (litellm_chat_history_v1) - Streaming completions via makeOpenAIChatCompletionRequest with AbortController stop support - MCP server picker (toggle servers on/off per conversation) - LiteLLM aesthetic: white/light-gray background, Ant Design blue (#1677ff) primary, system font - Sidebar2: Chat menu item opens in new tab via window.open * feat(chat-ui): responses API + MCP tool execution display - Switch /chat from chat completions to responses API (previous_response_id session chaining) - Add MCP server picker with search filter in chat input bar - Show MCP tool call events (list_tools + call_tool) inline in chat via MCPEventsDisplay - Add tool chip strip showing available tools when MCP servers are selected - Non-blocking MCP toggle: server added immediately, verification in background (works for no-auth MCPs like deepwiki) - Add truncateAfterMessage to useChatHistory for edit/retry - Sync activeConversationId on URL change (fixes stale conversation on new chat) - Add "Open Chat" shortcut button to sidebar * fix(chat-ui): switch to responses API, remove dead code, add tests - Switch handleSend from makeOpenAIChatCompletionRequest to makeOpenAIResponsesRequest with previous_response_id session chaining - Add responsesSessionId state; reset to null when starting a new conversation - Remove unused ChatInputBar.tsx and ModelSelector.tsx (dead code) - Add tests/test_litellm/test_chat_ui_responses_session.py covering previous_response_id forwarding and signature validation * fix(chat-ui): address greptile review issues - Reset responsesSessionId when activeConversationId changes (not just on new conversation) - Wire onMCPEvent callback into makeOpenAIResponsesRequest; render MCPEventsDisplay below messages - Clear mcpEvents on each new send - Explicitly filter history to user/assistant roles only (no tool-role casting) - Remove duplicate "Chat" menu item from sidebar (pinned button serves same purpose) - Make Sider a flex column so "Open Chat" button actually pins to bottom - Fix tests to intercept real HTTP requests and assert previous_response_id in body * fix(chat-ui): address greptile review feedback (greploop iteration 1) - Fix duplicate context: when responsesSessionId is set, only send the new user message as input (prior context is already server-side via session chaining). Full history is still sent on the first turn. - Fix ephemeral MCP events: store events per-message in ChatMessage.mcpEvents instead of ephemeral component state. Events now survive across turns and render inline below each assistant response via MCPEventsDisplay. - Remove stale mcpEvents useState and ephemeral panel at bottom of chat. * fix(chat-ui): address greptile review feedback (greploop iteration 2) - Fix stale session on edit/retry: derive previousResponseId as null when historyOverride is set so edit/retry always starts a fresh Responses API session rather than chaining off a now-invalid prior session - Fix unsafe MCPEvent cast: import MCPEvent directly from MCPEventsDisplay into types.ts and type ChatMessage.mcpEvents as MCPEvent[], eliminating the bare 'as MCPEvent[]' cast in ChatMessages.tsx * fix(chat-ui): fix MCPEvent layering, batch localStorage writes, module-level test imports - Move MCPEvent interface definition into chat/types.ts (single source of truth) - MCPEventsDisplay.tsx now imports MCPEvent from types.ts instead of defining it locally - Batch MCP event localStorage writes: accumulate during stream, persist once in finally - Move test imports to module level per PEP 8 convention * fix(chat-ui): fix MCPEvent import path and rename truncateFromMessage - responses_api.tsx now imports MCPEvent directly from chat/types (not via MCPEventsDisplay re-export) - Remove the now-unnecessary MCPEvent re-export from MCPEventsDisplay.tsx - Rename truncateAfterMessage → truncateFromMessage: the function removes the target message and all subsequent ones (not just what comes after), so the new name accurately describes the behavior * fix(responses-api): fix whitespace token filter and MCP server URL construction - Drop the delta.trim() whitespace filter that was silently swallowing spaces and newlines during streaming, causing words to concatenate and paragraphs to collapse. Only skip truly empty strings (delta.length > 0). - Use proxyBaseUrl for MCP server_url construction instead of the hardcoded relative path "litellm_proxy/mcp", so non-root deployments route correctly. * fix(responses-api): use unique server_label per MCP server to prevent tool routing collisions * fix(chat-ui): move MCPEvent to shared mcp_tools/types, skip partial events on abort - Move MCPEvent interface to mcp_tools/types.tsx (shared with MCPServer/MCPTool), eliminating the playground→chat cross-module dependency. chat/types.ts and both playground components now import from mcp_tools/types. - Only persist accumulated MCP events when the stream completes cleanly; aborted or errored turns drop partial events to avoid showing incomplete tool calls. * fix(responses-api): use server_name for MCP URL routing, fix test path - Use server_name (not alias) as the URL path segment for MCP server_url; alias is a display name that may differ from the registered proxy route. URL-encode the path to handle names with spaces/special characters. - Fix sys.path.insert in tests to use __file__-relative path so tests pass regardless of which directory pytest is invoked from. * fix(chat-ui): fix stale session after failed edit, clean MCP event persistence, unique server_label - Eagerly call setResponsesSessionId(null) when historyOverride is set so a failed/aborted edit does not leave a stale session contaminating the next turn - Replace abort-signal check with streamCompletedCleanly flag to correctly skip MCP event persistence on both abort and non-abort errors (network/API failures) - Use server_name (unique) as server_label instead of alias to prevent silent tool-routing failures when two MCP servers share the same display name |

In total litellm runs 1000+ tests
[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/test_litellm
This folder can only run mock tests.
