Replace all bare print() calls with proper logging using Python's
standard logging module across the deerflow harness package.
Changes across 8 files (16 print statements replaced):
- agents/middlewares/clarification_middleware.py: use logger.info/debug
- agents/middlewares/memory_middleware.py: use logger.debug
- agents/middlewares/thread_data_middleware.py: use logger.debug
- agents/middlewares/view_image_middleware.py: use logger.debug
- agents/memory/queue.py: use logger.info/debug/warning/error
- agents/lead_agent/prompt.py: use logger.error
- skills/loader.py: use logger.warning
- skills/parser.py: use logger.error
Each file follows the established codebase convention:
import logging
logger = logging.getLogger(__name__)
Log levels chosen based on message semantics:
- debug: routine operational details (directory creation, timer resets)
- info: significant state changes (memory queued, updates processed)
- warning: recoverable issues (config load failures, skipped updates)
- error: unexpected failures (parsing errors, memory update errors)
Note: client.py is intentionally excluded as it uses print() for
CLI output, which is the correct behavior for a command-line client.

* refactor: extract shared skill installer and upload manager to harness
Move duplicated business logic from Gateway routers and Client into
shared harness modules, eliminating code duplication.
New shared modules:
- deerflow.skills.installer: 6 functions (zip security, extraction, install)
- deerflow.uploads.manager: 7 functions (normalize, deduplicate, validate,
list, delete, get_uploads_dir, ensure_uploads_dir)
Key improvements:
- SkillAlreadyExistsError replaces stringly-typed 409 status routing
- normalize_filename rejects backslash-containing filenames
- Read paths (list/delete) no longer mkdir via get_uploads_dir
- Write paths use ensure_uploads_dir for explicit directory creation
- list_files_in_dir does stat inside scandir context (no re-stat)
- install_skill_from_archive uses single is_file() check (one syscall)
- Fix agent config key not reset on update_mcp_config/update_skill
Tests: 42 new (22 installer + 20 upload manager) + client hardening
* refactor: centralize upload URL construction and clean up installer
- Extract upload_virtual_path(), upload_artifact_url(), enrich_file_listing()
into shared manager.py, eliminating 6 duplicated URL constructions across
Gateway router and Client
- Derive all upload URLs from VIRTUAL_PATH_PREFIX constant instead of
hardcoded "mnt/user-data/uploads" strings
- Eliminate TOCTOU pre-checks and double file read in installer — single
ZipFile() open with exception handling replaces is_file() + is_zipfile()
+ ZipFile() sequence
- Add missing re-exports: ensure_uploads_dir in uploads/__init__.py,
SkillAlreadyExistsError in skills/__init__.py
- Remove redundant .lower() on already-lowercase CONVERTIBLE_EXTENSIONS
- Hoist sandbox_uploads_dir(thread_id) before loop in uploads router
* fix: add input validation for thread_id and filename length
- Reject thread_id containing unsafe filesystem characters (only allow
alphanumeric, hyphens, underscores, dots) — prevents 500 on inputs
like <script> or shell metacharacters
- Reject filenames longer than 255 bytes (OS limit) in normalize_filename
- Gateway upload router maps ValueError to 400 for invalid thread_id
* fix: address PR review — symlink safety, input validation coverage, error ordering
- list_files_in_dir: use follow_symlinks=False to prevent symlink metadata
leakage; check is_dir() instead of exists() for non-directory paths
- install_skill_from_archive: restore is_file() pre-check before extension
validation so error messages match the documented exception contract
- validate_thread_id: move from ensure_uploads_dir to get_uploads_dir so
all entry points (upload/list/delete) are protected
- delete_uploaded_file: catch ValueError from thread_id validation (was 500)
- requires_llm marker: also skip when OPENAI_API_KEY is unset
- e2e fixture: update TitleMiddleware exclusion comment (kept filtering —
middleware triggers extra LLM calls that add non-determinism to tests)
* chore: revert uv.lock to main — no dependency changes in this PR
* fix: use monkeypatch for global config in e2e fixture to prevent test pollution
The e2e_env fixture was calling set_title_config() and
set_summarization_config() directly, which mutated global singletons
without automatic cleanup. When pytest ran test_client_e2e.py before
test_title_middleware_core_logic.py, the leaked enabled=False caused
5 title tests to fail in CI.
Switched to monkeypatch.setattr on the module-level private variables
so pytest restores the originals after each test.
* fix: address code review — URL encoding, API consistency, test isolation
- upload_artifact_url: percent-encode filename to handle spaces/#/?
- deduplicate_filename: mutate seen set in place (caller no longer
needs manual .add() — less error-prone API)
- list_files_in_dir: document that size is int, enrich stringifies
- e2e fixture: monkeypatch _app_config instead of set_app_config()
to prevent global singleton pollution (same pattern as title/summarization fix)
- _make_e2e_config: read LLM connection details from env vars so
external contributors can override defaults
- Update tests to match new deduplicate_filename contract
* docs: rewrite RFC in English and add alternatives/breaking changes sections
* fix: address code review feedback on PR #1202
- Rename deduplicate_filename to claim_unique_filename to make
the in-place set mutation explicit in the function name
- Replace PermissionError with PathTraversalError(ValueError) for
path traversal detection — malformed input is 400, not 403
* fix: set _app_config_is_custom in e2e test fixture to prevent config.yaml lookup in CI

os.walk() does not follow symbolic links by default. This means
custom skills installed as symlinks in skills/custom/ are discovered
as directories but never descended into, so their SKILL.md files
are never found and the skills silently fail to load.
Adding followlinks=True fixes this for users who symlink skill
directories from external projects into the custom skills folder.

* 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

* fix: handle empty config and search parent dirs for config.example.yaml
Address Copilot review comments on PR #1131:
- Guard against yaml.safe_load() returning None for empty config files
- Search parent directories for config.example.yaml instead of only
looking next to config.yaml, fixing detection in common setups

* fix: correct skills root path depth and config_version type coercion
- loader.py: fix get_skills_root_path() to use 5 parent levels (was 3)
after harness split, file lives at packages/harness/deerflow/skills/
so parent×3 resolved to backend/packages/harness/ instead of backend/
- 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")
- tests: add regression tests for both fixes
