* feat: track token usage per conversation turn
Add token usage tracking to the streaming API so consumers can monitor
cost per turn without additional API calls.
Changes:
1. _serialize_message now includes usage_metadata for AI messages in
values events, exposing input_tokens/output_tokens/total_tokens
from LangChain's native metadata.
2. stream() accumulates token usage across all AI messages in a turn
and emits the cumulative totals in the end event:
{usage: {input_tokens: N, output_tokens: N, total_tokens: N}}
3. Each messages-tuple AI event with text content now includes a
per-message usage_metadata field for granular tracking.
This enables the frontend to display token consumption per turn,
support cost-aware UX, and let users monitor API spending.
10 tests added covering serialization passthrough and cumulative
aggregation logic.

* fix: address Copilot review - use Mapping access for usage_metadata
- Replace getattr(usage, 'input_tokens', 0) with usage.get('input_tokens', 0)
since LangChain usage_metadata is a dict, not an object
- Remove unused 'import pytest' (fixes Ruff F401)
- Add proper stream() integration tests for cumulative usage in end event
and per-message usage_metadata in messages-tuple events

This PR improves MiniMax Code Plan integration in DeerFlow by fixing three issues in the current flow: stream errors were not clearly surfaced in the UI, the frontend could not display the actual provider model ID, and MiniMax reasoning output could leak into final assistant content as inline <think>...</think>. The change adds a MiniMax-specific adapter, exposes real model IDs end-to-end, and adds a frontend fallback for historical messages.

* feat(manager): add bootstrap command to initialize soul.md in correct place
* feat(channels): add /bootstrap command to IM channels
Add a `/bootstrap` command that routes to the chat handler with
`is_bootstrap: True` in the run context, allowing the agent to invoke
its setup/initialization flow (e.g. `setup_agent`).
- The text after `/bootstrap` is forwarded as the chat message; when
omitted a default "Initialize workspace" message is used.
- Feishu channels use the streaming path as with normal chat.
- No changes to ChannelStore — bootstrap is stateless and triggered
purely by the command.
- Update /help output to include /bootstrap.
- Add 5 tests covering: text/no-text variants, Feishu streaming path,
thread creation, and help text.

* fix(scripts): handle docker-init failures gracefully for private registry
The make docker-init command was failing on Linux environments when users
could not access the private Volces container registry. This commonly
occurs in corporate intranet environments with proxies or for users
without registry credentials.
Changes:
- Detect sandbox mode from config.yaml before attempting image pull
- Skip image pull entirely for local sandbox mode (default)
- Gracefully handle pull failures with informative messages
- Update setup-sandbox Makefile target with same error handling

* 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

The cleanup() trap kills "next dev" and "next start" but not
"next-server". Since "next start" forks a "next-server" child
process, killing the parent may leave the child running as a
zombie, holding port 3000. The startup teardown block (line 35)
already handles this, but the Ctrl+C / SIGTERM trap did not.

* 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.

* 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

* 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
* fix: address PR #1056 review feedback for LoopDetectionMiddleware
- Remove unused imports (Awaitable, Callable, ModelCallResult,
ModelRequest, ModelResponse, AIMessage) from loop_detection_middleware
- Remove unused pytest import from test file
- Fix _hash_tool_calls sort key: sort by (name, serialized args) for
deterministic hashing when multiple calls share the same tool name
- Revert subagent_enabled default to False in agent.py to match
DeerFlowClient and channel defaults

* feat: add dev-daemon target for background development mode
Add a new make dev-daemon target that allows running DeerFlow services
in background mode without keeping the terminal connection.
Following the pattern of PR #1042, the implementation uses a dedicated
shell script (scripts/start-daemon.sh) for better maintainability.
- Create scripts/start-daemon.sh for daemon mode startup
- Add dev-daemon target to Makefile
- Each service writes logs to separate files (langgraph, gateway, frontend, nginx)
- Services can be stopped with make stop
- Use nohup for proper daemon process detachment
- Add cleanup on failure when services fail to start
- Use more specific pkill pattern to avoid killing unrelated nginx processes
* refactor: use wait-for-port.sh instead of hardcoded sleep in daemon script
* refactor: use specific nginx process pattern to avoid killing unrelated processes

- Use router.replace() instead of history.replaceState() so Next.js
router's internal state is updated on chat start. This ensures
subsequent "New Chat" clicks are treated as a real cross-route
navigation (actual-id → "new") rather than a no-op same-path
navigation, which was causing stale content to persist.
- In ChatLayout, increment the SubtasksProvider key only when
navigating TO "new" from a non-"new" route. This forces a full
remount for a fresh new-chat state without remounting when the URL
transitions from "new" → actual-id (which would interrupt streaming).
