* feat: add Novita AI as optional LLM provider
Adds Novita AI (https://novita.ai) as an optional, OpenAI-compatible
LLM provider.
Changes:
- Added Novita model configuration example in config.example.yaml
- Added NOVITA_API_KEY to .env.example
Usage: Set NOVITA_API_KEY in your environment and use novita-gpt-4
as the model name.
* update correct model info
* Update README.md

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
verifying that backend services are listening and by terminating on
misconfiguration at launch. Adds more robust feedback to developers when
API startup fails, reducing silent misconfigurations and speeding up
troubleshooting.
* Initial plan
* Implement suggestions from PR #892: fix env var checks and improve error logging

* feat(subagents): make subagent timeout configurable via config.yaml
- Add SubagentsAppConfig supporting global and per-agent timeout_seconds
- Load subagents config section in AppConfig.from_file()
- Registry now applies config.yaml overrides without mutating builtin defaults
- Polling safety-net in task_tool is now dynamic (execution timeout + 60s buffer)
- Document subagents section in config.example.yaml
- Add make test command and enforce TDD policy in CLAUDE.md
- Add 38 unit tests covering config validation, timeout resolution, registry
override behavior, and polling timeout formula

* feat(subagents): add logging for subagent timeout config and execution
- Log loaded timeout config (global default + per-agent overrides) on startup
- Log debug message in registry when config.yaml overrides a builtin timeout
- Include timeout in executor's async execution start log
- Log effective timeout and polling limit when a task is dispatched
- Fix UnboundLocalError: move max_poll_count assignment before logger.info

* feat: add LangSmith tracing integration
Add optional LangSmith tracing support that can be enabled via environment
variables (LANGSMITH_TRACING, LANGSMITH_API_KEY, LANGSMITH_PROJECT,
LANGSMITH_ENDPOINT). When enabled, a LangChainTracer callback is attached
to chat models and run metadata is injected for trace tagging.

The condition guarding ArtifactFilePreview only allowed markdown files
through, which prevented HTML files from reaching the preview component.
Added `language === "html"` to the condition so HTML artifacts render
correctly in preview mode.

* fix: move Key Citations to early position in reporter prompt to reduce URL hallucination
Move the Key Citations section from position 6 (end of report) to position 2
(immediately after title) in the reporter prompt. When citations are placed at
the end of a long report, LLMs tend to forget real URLs from source material
and fabricate plausible-looking but non-existent URLs.
Changes to src/prompts/reporter.md:
- Move Key Citations from section 6 to section 2 (right after Title)
- Add explicit anti-hallucination instructions: only use URLs from provided
source material, never fabricate or guess URLs
- Keep a repeated citation list at the end (section 7) for completeness
- Renumber all subsequent sections accordingly
- Update Notes section to reflect new structure
Tested with real DeerFlow backend + DuckDuckGo search:
- Before: multiple hallucinated URLs in report citations
- After: hallucinated URLs reduced significantly
Closes#825
* fix: move citations after observations in reporter_node to reduce URL hallucination
Previously, the citation message was appended BEFORE observation messages,
meaning it got buried under potentially thousands of chars of research data.
By the time the LLM reached the end of the context to generate the report,
it had 'forgotten' the real URLs and fabricated plausible-looking ones.
Now citations are appended AFTER compressed observations, placing them
closest to the LLM's generation point for maximum recall accuracy.

- Expand Docker Compose section in README.md and README_zh.md with:
- Explicit note that only root .env is used (not web/.env)
- Instructions to update NEXT_PUBLIC_API_URL for remote/LAN deployment
- Explanation that NEXT_PUBLIC_API_URL is a build-time variable
- Improve NEXT_PUBLIC_API_URL comments in root .env.example
Closes#527
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.
Explicitly prohibit parallel image generation to ensure each slide
can use the previous slide as a reference image for visual consistency.

Support configuring max_concurrent_subagents (2-4, default 3) through
config.configurable, with automatic clamping and dynamic prompt generation.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Extract get_skills_prompt_section() from apply_prompt_template() so
subagents can also receive the available skills list in their system
prompt. This allows subagents to discover and load skills via read_file,
just like the lead agent.
