* fix(harness): allow agent read access to /mnt/skills in local sandbox
Skill files under /mnt/skills/ were blocked by the path validator,
preventing agents from reading skill definitions. This change:
- Refactors `resolve_local_tool_path` into `validate_local_tool_path`,
a pure security gate that no longer resolves paths (left to the sandbox)
- Permits read-only access to the skills container path (/mnt/skills by
default, configurable via config.skills.container_path)
- Blocks write access to skills paths (PermissionError)
- Allows /mnt/skills in bash command path validation
- Adds `LocalSandbox.update_path_mappings` and injects per-thread
user-data mappings into the sandbox so all virtual-path resolution
is handled uniformly by the sandbox layer
- Covers all new behaviour with tests
Fixes#1177

* refactor(sandbox): unify all virtual path resolution in tools.py
Move skills path resolution from LocalSandbox into tools.py so that all
virtual-to-host path translation (user-data and skills) lives in one
layer. LocalSandbox becomes a pure execution layer that receives only
real host paths — no more path_mappings, _resolve_path, or reverse
resolve logic.
This addresses architecture feedback that path resolution was split
across two layers (tools.py for user-data, LocalSandbox for skills),
making the flow hard to follow.

* fix(sandbox): address Copilot review — cache-on-success and error path masking
- Replace @lru_cache with manual cache-on-success for _get_skills_container_path
and _get_skills_host_path so transient failures at startup don't permanently
disable skills access.
- Add _sanitize_error() helper that masks host filesystem paths in error
messages via mask_local_paths_in_output before returning them to the agent.
- Apply _sanitize_error() to all catch-all (Exception/OSError) handlers in
sandbox tool functions to prevent host path leakage in error output.
- Remove unused lru_cache import.

* feat(tools): add tool_search for deferred MCP tool loading
When multiple MCP servers are enabled, total tool count can exceed 30-50,
causing context bloat and degraded tool selection accuracy. This adds a
deferred tool loading mechanism controlled by `tool_search.enabled` config.
- Add ToolSearchConfig with single `enabled` field
- Add DeferredToolRegistry with regex search (select:, +keyword, keyword)
- Add tool_search tool returning OpenAI-compatible function JSON
- Add DeferredToolFilterMiddleware to hide deferred schemas from bind_tools
- Add <available-deferred-tools> section to system prompt
- Enable MCP tool_name_prefix to prevent cross-server name collisions
- Add 34 unit tests covering registry, tool, prompt, and middleware
* fix: reset stale deferred registry and bump config_version
- Reset deferred registry upfront in get_available_tools() to prevent
stale tool entries when MCP servers are disabled between calls
- Bump config_version to 2 for new tool_search config field

Inline citations in report body use [citation:Title](URL) for pill/badge style.
Sources section uses plain [Title](URL) for simple underlined link style.
* fix(frontend): render plain links as underlined text in artifact markdown
Only links with citation: prefix render as Badge pills.
Regular links in Sources section now render as underlined text links.

* refactor: extract shared utils to break harness→app cross-layer imports
Move _validate_skill_frontmatter to src/skills/validation.py and
CONVERTIBLE_EXTENSIONS + convert_file_to_markdown to src/utils/file_conversion.py.
This eliminates the two reverse dependencies from client.py (harness layer)
into gateway/routers/ (app layer), preparing for the harness/app package split.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* refactor: split backend/src into harness (deerflow.*) and app (app.*)
Physically split the monolithic backend/src/ package into two layers:
- **Harness** (`packages/harness/deerflow/`): publishable agent framework
package with import prefix `deerflow.*`. Contains agents, sandbox, tools,
models, MCP, skills, config, and all core infrastructure.
- **App** (`app/`): unpublished application code with import prefix `app.*`.
Contains gateway (FastAPI REST API) and channels (IM integrations).
Key changes:
- Move 13 harness modules to packages/harness/deerflow/ via git mv
- Move gateway + channels to app/ via git mv
- Rename all imports: src.* → deerflow.* (harness) / app.* (app layer)
- Set up uv workspace with deerflow-harness as workspace member
- Update langgraph.json, config.example.yaml, all scripts, Docker files
- Add build-system (hatchling) to harness pyproject.toml
- Add PYTHONPATH=. to gateway startup commands for app.* resolution
- Update ruff.toml with known-first-party for import sorting
- Update all documentation to reflect new directory structure
Boundary rule enforced: harness code never imports from app.
All 429 tests pass. Lint clean.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* chore: add harness→app boundary check test and update docs
Add test_harness_boundary.py that scans all Python files in
packages/harness/deerflow/ and fails if any `from app.*` or
`import app.*` statement is found. This enforces the architectural
rule that the harness layer never depends on the app layer.
Update CLAUDE.md to document the harness/app split architecture,
import conventions, and the boundary enforcement test.

* feat: add config versioning with auto-upgrade on startup
When config.example.yaml schema changes, developers' local config.yaml
files can silently become outdated. This adds a config_version field and
auto-upgrade mechanism so breaking changes (like src.* → deerflow.*
renames) are applied automatically before services start.
- Add config_version: 1 to config.example.yaml
- Add startup version check warning in AppConfig.from_file()
- Add scripts/config-upgrade.sh with migration registry for value replacements
- Add `make config-upgrade` target
- Auto-run config-upgrade in serve.sh and start-daemon.sh before starting services
- Add config error hints in service failure messages

- app_config.py: coerce config_version to int() before comparison in
_check_config_version() to prevent TypeError when YAML stores value
as string (e.g. config_version: "1")

* feat(feishu): stream updates on a single card
* fix(feishu): ensure final message on stream error and warn on missing card ID
- Wrap streaming loop in try/except/finally so a is_final=True outbound
message is always published, even when the LangGraph stream breaks
mid-way. This prevents _running_card_ids memory leaks and ensures the
Feishu card shows a DONE reaction instead of hanging on "Working on it".
- Log a warning when _ensure_running_card gets no message_id back from
the Feishu reply API, making silent fallback to new-card behavior
visible in logs.
- Add test_handle_feishu_stream_error_still_sends_final to cover the
error path.
- Reformat service.py dict comprehension (ruff format, no logic change).

* feat: add LoopDetectionMiddleware to break repetitive tool call loops
Adds a new AgentMiddleware that detects when the agent is stuck calling
the same tools with the same arguments repeatedly, which currently runs
until the recursion limit kills the run.
Detection: per-thread sliding window of tool call hashes (name + args).
- Warn threshold (default 3): injects a "wrap up" system message
- Hard limit (default 5): strips tool_calls, forcing final text output
Includes 13 unit tests covering hashing, thresholds, window sliding,
reset, and edge cases.
Closes#1055

- Remove unused imports (Awaitable, Callable, ModelCallResult,
ModelRequest, ModelResponse, AIMessage) from loop_detection_middleware
- Remove unused pytest import from test file

* fix: preserve conversation context in Telegram private chats
In private (1-on-1) chats, set topic_id=None so all messages map to a
single DeerFlow thread per chat instead of creating a new thread for

chats so /new correctly targets the default thread.
Group chat behavior is unchanged (reply_to or msg_id as topic_id).

* fix(subagents): cleanup background tasks after completion to prevent memory leak
Added cleanup_background_task() function to remove completed subagent results
from the global _background_tasks dict. Found a small issue: completed tasks
were never removed, causing memory to grow indefinitely with each subagent
execution.
Alternative approaches considered:
- Future + SubagentHandle pattern: Not chosen due to requiring refactoring
Chose the simple cleanup approach for minimal code changes while effectively
resolving the memory leak.
Changes:
- Add cleanup_background_task() in executor.py
- Call cleanup in all task_tool return paths (completed, failed, timed out)
* fix(subagents): prevent race condition in background task cleanup
Address Copilot review feedback on memory leak fix:
- Add terminal state check in cleanup_background_task() to only remove
tasks that are COMPLETED/FAILED/TIMED_OUT or have completed_at set
- Remove cleanup call from polling safety-timeout branch in task_tool
since the task may still be running
- Add comprehensive tests for cleanup behavior including:
- Verification that cleanup is called on terminal states
- Verification that cleanup is NOT called on polling timeout
- Tests for terminal state check logic in executor
This prevents KeyError when the background executor tries to update
a task that was prematurely removed from _background_tasks.

* 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

- 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: "
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* 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').

- 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
