* fix(subagent): support async MCP tools in subagent executor
SubagentExecutor.execute() was synchronous and could not handle async-only tools like MCP tools. This caused failures when trying to use MCP tools within subagents.
Changes:
- Add _aexecute() async method using agent.astream() for async execution
- Refactor execute() to use asyncio.run() wrapping _aexecute()
- This allows subagents to use async tools (MCP) within ThreadPoolExecutor
* test(subagent): add unit tests for executor async/sync paths
Add comprehensive tests covering:
- Async _aexecute() with success/error cases
- Sync execute() wrapper using asyncio.run()
- Async tool (MCP) support verification
- Thread pool execution safety
* fix(subagent): subagent-test-circular-depend
- Use session-scoped fixture with delayed import to handle circular dependencies
without affecting other test modules

- replace with explicit runtime deps:
- regenerate after dependency changes
- make deterministic by patching
to avoid leaked global affecting expected paths
* feat(upload): implement optimistic UI for file uploads and enhance message handling
* feat(middleware): enhance file handling by collecting historical uploads from directory
* feat(thread-title): update page title handling for new threads and improve loading state
* feat(uploads-middleware): enhance file extraction by verifying file existence in uploads directory
* feat(thread-stream): update file path reference to use virtual_path for uploads
* feat(tests): add core behaviour tests for UploadsMiddleware
* feat(tests): remove unused pytest import from test_uploads_middleware_core_logic.py
* feat: enhance file upload handling and localization support
- Update UploadsMiddleware to validate filenames more robustly.
- Modify MessageListItem to parse uploaded files from raw content for backward compatibility.
- Add localization for uploading messages in English and Chinese.
- Introduce parseUploadedFiles utility to extract uploaded files from message content.
* fix(memory): prevent file upload events from persisting in long-term memory
Uploaded files are session-scoped and unavailable in future sessions.
Previously, upload interactions were recorded in memory, causing the
agent to search for non-existent files in subsequent conversations.
Changes:
- memory_middleware: skip human messages containing <uploaded_files>
and their paired AI responses from the memory queue
- updater: post-process generated memory to strip upload mentions
before saving to file
- prompt: instruct the memory LLM to ignore file upload events
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(memory): address Copilot review feedback on upload filtering
- memory_middleware: strip <uploaded_files> block from human messages
instead of dropping the entire turn; only skip the turn (and paired
AI response) when nothing remains after stripping
- updater: narrow the upload-scrubbing regex to explicit upload events
(avoids false-positive removal of "User works with CSV files" etc.);
also filter upload-event facts from the facts array
- prompt: move `import re` to module scope; skip upload-only human
messages (empty after stripping) rather than appending "User: "

* fix(memory): allow optional words between 'upload' and 'file' in scrub regex
The previous pattern required 'uploading file' with no intervening words,
so 'uploading a test file' was not matched and leaked into long-term memory.
Allow up to 3 modifier words between the verb and noun (e.g. 'uploading a
test file', 'uploaded the attachment').

* test(memory): add unit tests for upload filtering in memory pipeline
Covers _filter_messages_for_memory and _strip_upload_mentions_from_memory
per Copilot review suggestion. 15 test cases verify:
- Upload-only turns (and paired AI responses) are excluded from memory queue
- User's real question is preserved when combined with an upload block
- Upload file paths are never present in filtered message content
- Intermediate tool messages are always excluded
- Multi-turn conversations: only the upload turn is dropped
- Multimodal (list-content) human messages are handled
- Upload-event sentences are removed from summaries and facts
- Legitimate file-related facts (CSV preferences, PDF exports) are preserved
- "uploading a test file" (words between verb and noun) is caught by regex

Validate that all dict-returning client methods conform to Gateway
Pydantic response models (ModelsListResponse, ModelResponse,
SkillsListResponse, SkillResponse, SkillInstallResponse,
McpConfigResponse, UploadResponse, MemoryConfigResponse,

Previously used before_model which returned {"messages": patches}, causing
LangGraph's add_messages reducer to append patches at the end of the message
list. This resulted in invalid ordering (ToolMessage after a HumanMessage)
that LLMs reject with tool call ID mismatch errors.
Switch to wrap_model_call/awrap_model_call to insert synthetic ToolMessages
immediately after each dangling AIMessage before the request reaches the LLM,
without persisting the patches to state.

* Enforces config env var checks and improves startup handling
Ensures critical environment variables are validated during config resolution,
raising clear errors if missing. Improves server startup reliability by

API startup fails, reducing silent misconfigurations and speeding up
troubleshooting.

Unifies market analysis, data analysis, and consulting reporting into a comprehensive consulting-analysis skill, enabling a two-phase workflow from analysis framework design to professional report generation. Introduces a DuckDB-based data analysis utility for Excel/CSV files and a chart-visualization skill with a flexible JS interface and extensive chart type documentation. Removes the legacy market analysis skill to streamline report generation and improve extensibility for consulting and data-driven workflows.
* Adds Kubernetes sandbox provisioner support
* Improves Docker dev setup by standardizing host paths
Replaces hardcoded host paths with a configurable root directory,
making the development environment more portable and easier to use
across different machines. Automatically sets the root path if not
already defined, reducing manual setup steps.
Support configuring max_concurrent_subagents (2-4, default 3) through
config.configurable, with automatic clamping and dynamic prompt generation.

Strengthen the SUBAGENT_SECTION prompt to prevent the model from launching
more than 3 subagents in a single response. When >3 sub-tasks are needed,

main subagent instructions, and critical reminders.

Add two new middlewares to improve robustness of the agent pipeline:
