-name: backend-code-review
-description: Review backend code for quality, security, maintainability, and best practices based on established checklist rules. Use when the user requests a review, analysis, or improvement of backend files (e.g., `.py`) under the `api/` directory. Do NOT use for frontend files (e.g., `.tsx`, `.ts`, `.js`). Supports pending-change review, code snippets review, and file-focused review.

-# Backend Code Review
-
-## When to use this skill
-
-Use this skill whenever the user asks to **review, analyze, or improve** backend code (e.g., `.py`) under the `api/` directory. Supports the following review modes:
-
-- **Pending-change review**: when the user asks to review current changes (inspect staged/working-tree files slated for commit to get the changes).
-- **Code snippets review**: when the user pastes code snippets (e.g., a function/class/module excerpt) into the chat and asks for a review.
-- **File-focused review**: when the user points to specific files and asks for a review of those files (one file or a small, explicit set of files, e.g., `api/...`, `api/app.py`).
-
-Do NOT use this skill when:
-
-- The request is about frontend code or UI (e.g., `.tsx`, `.ts`, `.js`, `web/`).
-- The user is not asking for a review/analysis/improvement of backend code.
-- The scope is not under `api/` (unless the user explicitly asks to review backend-related changes outside `api/`).
-
-## How to use this skill
-
-Follow these steps when using this skill:
-
-1. **Identify the review mode** (pending-change vs snippet vs file-focused) based on the user’s input. Keep the scope tight: review only what the user provided or explicitly referenced.
-2. Follow the rules defined in **Checklist** to perform the review. If no Checklist rule matches, apply **General Review Rules** as a fallback to perform the best-effort review.
-3. Compose the final output strictly follow the **Required Output Format**.
-
-Notes when using this skill:
-- Always include actionable fixes or suggestions (including possible code snippets).
-- Use best-effort `File:Line` references when a file path and line numbers are available; otherwise, use the most specific identifier you can.
-
-## Checklist
-
-- db schema design: if the review scope includes code/files under `api/models/` or `api/migrations/`, follow [references/db-schema-rule.md](references/db-schema-rule.md) to perform the review
-- architecture: if the review scope involves controller/service/core-domain/libs/model layering, dependency direction, or moving responsibilities across modules, follow [references/architecture-rule.md](references/architecture-rule.md) to perform the review
-- repositories abstraction: if the review scope contains table/model operations (e.g., `select(...)`, `session.execute(...)`, joins, CRUD) and is not under `api/repositories`, `api/core/repositories`, or `api/extensions/*/repositories/`, follow [references/repositories-rule.md](references/repositories-rule.md) to perform the review
-- sqlalchemy patterns: if the review scope involves SQLAlchemy session/query usage, db transaction/crud usage, or raw SQL usage, follow [references/sqlalchemy-rule.md](references/sqlalchemy-rule.md) to perform the review

-# Rule Catalog — Architecture
-
-## Scope
-- Covers: controller/service/core-domain/libs/model layering, dependency direction, responsibility placement, observability-friendly flow.
-
-## Rules
-
-### Keep business logic out of controllers
-- Category: maintainability
-- Severity: critical
-- Description: Controllers should parse input, call services, and return serialized responses. Business decisions inside controllers make behavior hard to reuse and test.
-- Suggested fix: Move domain/business logic into the service or core/domain layer. Keep controller handlers thin and orchestration-focused.
-- Example:
-  - Bad:
-    ```python
-    @bp.post("/apps/<app_id>/publish")
-    def publish_app(app_id: str):
-        payload = request.get_json() or {}
-        if payload.get("force") and current_user.role != "admin":
-            raise ValueError("only admin can force publish")
-        app = App.query.get(app_id)
-        app.status = "published"
-        db.session.commit()
-        return {"result": "ok"}
-    ```
-  - Good:
-    ```python
-    @bp.post("/apps/<app_id>/publish")
-    def publish_app(app_id: str):
-        payload = PublishRequest.model_validate(request.get_json() or {})
-        app_service.publish_app(app_id=app_id, force=payload.force, actor_id=current_user.id)
-        return {"result": "ok"}
-    ```
-
-### Preserve layer dependency direction
-- Category: best practices
-- Severity: critical
-- Description: Controllers may depend on services, and services may depend on core/domain abstractions. Reversing this direction (for example, core importing controller/web modules) creates cycles and leaks transport concerns into domain code.
-- Suggested fix: Extract shared contracts into core/domain or service-level modules and make upper layers depend on lower, not the reverse.
-- Example:
-  - Bad:
-    ```python
-    # core/policy/publish_policy.py
-    from controllers.console.app import request_context
-
-    def can_publish() -> bool:
-        return request_context.current_user.is_admin
-    ```
-  - Good:
-    ```python
-    # core/policy/publish_policy.py
-    def can_publish(role: str) -> bool:
-        return role == "admin"
-
-    # service layer adapts web/user context to domain input
-    allowed = can_publish(role=current_user.role)
-    ```
-
-### Keep libs business-agnostic
-- Category: maintainability
-- Severity: critical
-- Description: Modules under `api/libs/` should remain reusable, business-agnostic building blocks. They must not encode product/domain-specific rules, workflow orchestration, or business decisions.
-- Suggested fix:
-  - If business logic appears in `api/libs/`, extract it into the appropriate `services/` or `core/` module and keep `libs` focused on generic, cross-cutting helpers.
-  - Keep `libs` dependencies clean: avoid importing service/controller/domain-specific modules into `api/libs/`.
-- Example:
-  - Bad:
-    ```python
-    # api/libs/conversation_filter.py
-    from services.conversation_service import ConversationService
-
-    def should_archive_conversation(conversation, tenant_id: str) -> bool:
-        # Domain policy and service dependency are leaking into libs.
-        service = ConversationService()
-        if service.has_paid_plan(tenant_id):
-            return conversation.idle_days > 90
-        return conversation.idle_days > 30
-    ```
-  - Good:
-    ```python
-    # api/libs/datetime_utils.py (business-agnostic helper)
-    def older_than_days(idle_days: int, threshold_days: int) -> bool:
-        return idle_days > threshold_days
-
-    # services/conversation_service.py (business logic stays in service/core)
-    from libs.datetime_utils import older_than_days
-
-    def should_archive_conversation(conversation, tenant_id: str) -> bool:
-        threshold_days = 90 if has_paid_plan(tenant_id) else 30
-        return older_than_days(conversation.idle_days, threshold_days)
-    ```

-# Rule Catalog — DB Schema Design
-
-## Scope
-- Covers: model/base inheritance, schema boundaries in model properties, tenant-aware schema design, index redundancy checks, dialect portability in models, and cross-database compatibility in migrations.
-- Does NOT cover: session lifecycle, transaction boundaries, and query execution patterns (handled by `sqlalchemy-rule.md`).
-
-## Rules
-
-### Do not query other tables inside `@property`
-- Category: [maintainability, performance]
-- Severity: critical
-- Description: A model `@property` must not open sessions or query other tables. This hides dependencies across models, tightly couples schema objects to data access, and can cause N+1 query explosions when iterating collections.
-- Suggested fix:
-  - Keep model properties pure and local to already-loaded fields.
-  - Move cross-table data fetching to service/repository methods.
-  - For list/batch reads, fetch required related data explicitly (join/preload/bulk query) before rendering derived values.
-- Example:
-  - Bad:
-    ```python
-    class Conversation(TypeBase):
-        __tablename__ = "conversations"
-
-        @property
-        def app_name(self) -> str:
-            with Session(db.engine, expire_on_commit=False) as session:
-                app = session.execute(select(App).where(App.id == self.app_id)).scalar_one()
-                return app.name
-    ```
-  - Good:
-    ```python
-    class Conversation(TypeBase):
-        __tablename__ = "conversations"
-
-        @property
-        def display_title(self) -> str:
-            return self.name or "Untitled"
-
-
-    # Service/repository layer performs explicit batch fetch for related App rows.
-    ```
-
-### Prefer including `tenant_id` in model definitions
-- Category: maintainability
-- Severity: suggestion
-- Description: In multi-tenant domains, include `tenant_id` in schema definitions whenever the entity belongs to tenant-owned data. This improves data isolation safety and keeps future partitioning/sharding strategies practical as data volume grows.
-- Suggested fix:
-  - Add a `tenant_id` column and ensure related unique/index constraints include tenant dimension when applicable.
-  - Propagate `tenant_id` through service/repository contracts to keep access paths tenant-aware.
-  - Exception: if a table is explicitly designed as non-tenant-scoped global metadata, document that design decision clearly.
-- Example:
-  - Bad:
-    ```python
-    from sqlalchemy.orm import Mapped
-
-    class Dataset(TypeBase):
-        __tablename__ = "datasets"
-        id: Mapped[str] = mapped_column(StringUUID, primary_key=True)
-        name: Mapped[str] = mapped_column(sa.String(255), nullable=False)
-    ```
-  - Good:
-    ```python
-    from sqlalchemy.orm import Mapped
-
-    class Dataset(TypeBase):
-        __tablename__ = "datasets"
-        id: Mapped[str] = mapped_column(StringUUID, primary_key=True)
-        tenant_id: Mapped[str] = mapped_column(StringUUID, nullable=False, index=True)
-        name: Mapped[str] = mapped_column(sa.String(255), nullable=False)
-    ```
-
-### Detect and avoid duplicate/redundant indexes
-- Category: performance
-- Severity: suggestion
-- Description: Review index definitions for leftmost-prefix redundancy. For example, index `(a, b, c)` can safely cover most lookups for `(a, b)`. Keeping both may increase write overhead and can mislead the optimizer into suboptimal execution plans.
-- Suggested fix:
-  - Before adding an index, compare against existing composite indexes by leftmost-prefix rules.
-  - Drop or avoid creating redundant prefixes unless there is a proven query-pattern need.
-  - Apply the same review standard in both model `__table_args__` and migration index DDL.
-- Example:
-  - Bad:
-    ```python
-    __table_args__ = (
-        sa.Index("idx_msg_tenant_app", "tenant_id", "app_id"),
-        sa.Index("idx_msg_tenant_app_created", "tenant_id", "app_id", "created_at"),
-    )
-    ```
-  - Good:
-    ```python
-    __table_args__ = (
-        # Keep the wider index unless profiling proves a dedicated short index is needed.
-        sa.Index("idx_msg_tenant_app_created", "tenant_id", "app_id", "created_at"),
-    )
-    ```
-
-### Avoid PostgreSQL-only dialect usage in models; wrap in `models.types`
-- Category: maintainability
-- Severity: critical
-- Description: Model/schema definitions should avoid PostgreSQL-only constructs directly in business models. When database-specific behavior is required, encapsulate it in `api/models/types.py` using both PostgreSQL and MySQL dialect implementations, then consume that abstraction from model code.
-- Suggested fix:
-  - Do not directly place dialect-only types/operators in model columns when a portable wrapper can be used.
-  - Add or extend wrappers in `models.types` (for example, `AdjustedJSON`, `LongText`, `BinaryData`) to normalize behavior across PostgreSQL and MySQL.
-- Example:
-  - Bad:
-    ```python
-    from sqlalchemy.dialects.postgresql import JSONB
-    from sqlalchemy.orm import Mapped
-
-    class ToolConfig(TypeBase):
-        __tablename__ = "tool_configs"
-        config: Mapped[dict] = mapped_column(JSONB, nullable=False)
-    ```
-  - Good:
-    ```python
-    from sqlalchemy.orm import Mapped
-
-    from models.types import AdjustedJSON
-
-    class ToolConfig(TypeBase):
-        __tablename__ = "tool_configs"
-        config: Mapped[dict] = mapped_column(AdjustedJSON(), nullable=False)
-    ```
-
-### Guard migration incompatibilities with dialect checks and shared types
-- Category: maintainability
-- Severity: critical
-- Description: Migration scripts under `api/migrations/versions/` must account for PostgreSQL/MySQL incompatibilities explicitly. For dialect-sensitive DDL or defaults, branch on the active dialect (for example, `conn.dialect.name == "postgresql"`), and prefer reusable compatibility abstractions from `models.types` where applicable.
-- Suggested fix:
-  - In migration upgrades/downgrades, bind connection and branch by dialect for incompatible SQL fragments.
-  - Reuse `models.types` wrappers in column definitions when that keeps behavior aligned with runtime models.
-  - Avoid one-dialect-only migration logic unless there is a documented, deliberate compatibility exception.
-- Example:
-  - Bad:
-    ```python
-    with op.batch_alter_table("dataset_keyword_tables") as batch_op:
-        batch_op.add_column(
-            sa.Column(
-                "data_source_type",
-                sa.String(255),
-                server_default=sa.text("'database'::character varying"),
-                nullable=False,
-            )
-        )
-    ```
-  - Good:
-    ```python
-    def _is_pg(conn) -> bool:
-        return conn.dialect.name == "postgresql"
-
-
-    conn = op.get_bind()
-    default_expr = sa.text("'database'::character varying") if _is_pg(conn) else sa.text("'database'")
-
-    with op.batch_alter_table("dataset_keyword_tables") as batch_op:
-        batch_op.add_column(
-            sa.Column("data_source_type", sa.String(255), server_default=default_expr, nullable=False)
-        )
-    ```

-# Rule Catalog - Repositories Abstraction
-
-## Scope
-- Covers: when to reuse existing repository abstractions, when to introduce new repositories, and how to preserve dependency direction between service/core and infrastructure implementations.
-- Does NOT cover: SQLAlchemy session lifecycle and query-shape specifics (handled by `sqlalchemy-rule.md`), and table schema/migration design (handled by `db-schema-rule.md`).
-
-## Rules
-
-### Introduce repositories abstraction
-- Category: maintainability
-- Severity: suggestion
-- Description: If a table/model already has a repository abstraction, all reads/writes/queries for that table should use the existing repository. If no repository exists, introduce one only when complexity justifies it, such as large/high-volume tables, repeated complex query logic, or likely storage-strategy variation.
-- Suggested fix:
-  - First check  `api/repositories`, `api/core/repositories`, and `api/extensions/*/repositories/` to verify whether the table/model already has a repository abstraction. If it exists, route all operations through it and add missing repository methods instead of bypassing it with ad-hoc SQLAlchemy access.
-  - If no repository exists, add one only when complexity warrants it (for example, repeated complex queries, large data domains, or multiple storage strategies), while preserving dependency direction (service/core depends on abstraction; infra provides implementation).
-- Example:
-  - Bad:
-    ```python
-    # Existing repository is ignored and service uses ad-hoc table queries.
-    class AppService:
-        def archive_app(self, app_id: str, tenant_id: str) -> None:
-            app = self.session.execute(
-                select(App).where(App.id == app_id, App.tenant_id == tenant_id)
-            ).scalar_one()
-            app.archived = True
-            self.session.commit()
-    ```
-  - Good:
-    ```python
-    # Case A: Existing repository must be reused for all table operations.
-    class AppService:
-        def archive_app(self, app_id: str, tenant_id: str) -> None:
-            app = self.app_repo.get_by_id(app_id=app_id, tenant_id=tenant_id)
-            app.archived = True
-            self.app_repo.save(app)
-
-    # If the query is missing, extend the existing abstraction.
-    active_apps = self.app_repo.list_active_for_tenant(tenant_id=tenant_id)
-    ```
-  - Bad:
-    ```python
-    # No repository exists, but large-domain query logic is scattered in service code.
-    class ConversationService:
-        def list_recent_for_app(self, app_id: str, tenant_id: str, limit: int) -> list[Conversation]:
-            ...
-            # many filters/joins/pagination variants duplicated across services
-    ```
-  - Good:

-    # Case B: Introduce repository for large/complex domains or storage variation.

-# Rule Catalog — SQLAlchemy Patterns
-
-## Scope
-- Covers: SQLAlchemy session and transaction lifecycle, query construction, tenant scoping, raw SQL boundaries, and write-path concurrency safeguards.
-- Does NOT cover: table/model schema and migration design details (handled by `db-schema-rule.md`).
-
-## Rules
-
-### Use Session context manager with explicit transaction control behavior
-- Category: best practices
-- Severity: critical
-- Description: Session and transaction lifecycle must be explicit and bounded on write paths. Missing commits can silently drop intended updates, while ad-hoc or long-lived transactions increase contention, lock duration, and deadlock risk.
-- Suggested fix:
-  - Use **explicit `session.commit()`** after completing a related write unit.
-  - Or use **`session.begin()` context manager** for automatic commit/rollback on a scoped block.
-  - Keep transaction windows short: avoid network I/O, heavy computation, or unrelated work inside the transaction.
-- Example:
-  - Bad:
-    ```python
-    # Missing commit: write may never be persisted.
-    with Session(db.engine, expire_on_commit=False) as session:
-        run = session.get(WorkflowRun, run_id)
-        run.status = "cancelled"
-
-    # Long transaction: external I/O inside a DB transaction.
-    with Session(db.engine, expire_on_commit=False) as session, session.begin():
-        run = session.get(WorkflowRun, run_id)
-        run.status = "cancelled"
-        call_external_api()
-    ```
-  - Good:
-    ```python
-    # Option 1: explicit commit.
-    with Session(db.engine, expire_on_commit=False) as session:
-        run = session.get(WorkflowRun, run_id)
-        run.status = "cancelled"
-        session.commit()
-
-    # Option 2: scoped transaction with automatic commit/rollback.
-    with Session(db.engine, expire_on_commit=False) as session, session.begin():
-        run = session.get(WorkflowRun, run_id)
-        run.status = "cancelled"
-
-    # Keep non-DB work outside transaction scope.
-    call_external_api()
-    ```
-
-### Enforce tenant_id scoping on shared-resource queries
-- Category: security
-- Severity: critical
-- Description: Reads and writes against shared tables must be scoped by `tenant_id` to prevent cross-tenant data leakage or corruption.
-- Suggested fix: Add `tenant_id` predicate to all tenant-owned entity queries and propagate tenant context through service/repository interfaces.
-- Example:
-  - Bad:
-    ```python
-    stmt = select(Workflow).where(Workflow.id == workflow_id)
-    workflow = session.execute(stmt).scalar_one_or_none()
-    ```
-  - Good:
-    ```python
-    stmt = select(Workflow).where(
-        Workflow.id == workflow_id,
-        Workflow.tenant_id == tenant_id,
-    )
-    workflow = session.execute(stmt).scalar_one_or_none()
-    ```
-
-### Prefer SQLAlchemy expressions over raw SQL by default
-- Category: maintainability
-- Severity: suggestion
-- Description: Raw SQL should be exceptional. ORM/Core expressions are easier to evolve, safer to compose, and more consistent with the codebase.
-- Suggested fix: Rewrite straightforward raw SQL into SQLAlchemy `select/update/delete` expressions; keep raw SQL only when required by clear technical constraints.
-- Example:
-  - Bad:
-    ```python
-    row = session.execute(
-        text("SELECT * FROM workflows WHERE id = :id AND tenant_id = :tenant_id"),
-        {"id": workflow_id, "tenant_id": tenant_id},
-    ).first()
-    ```
-  - Good:
-    ```python
-    stmt = select(Workflow).where(
-        Workflow.id == workflow_id,
-        Workflow.tenant_id == tenant_id,
-    )
-    row = session.execute(stmt).scalar_one_or_none()
-    ```

-### Protect write paths with concurrency safeguards
-- Category: quality
-- Severity: critical
-- Description: Multi-writer paths without explicit concurrency control can silently overwrite data. Choose the safeguard based on contention level, lock scope, and throughput cost instead of defaulting to one strategy.
-- Suggested fix:
-  - **Optimistic locking**: Use when contention is usually low and retries are acceptable. Add a version (or updated_at) guard in `WHERE` and treat `rowcount == 0` as a conflict.
-  - **Redis distributed lock**: Use when the critical section spans multiple steps/processes (or includes non-DB side effects) and you need cross-worker mutual exclusion.
-  - **SELECT ... FOR UPDATE**: Use when contention is high on the same rows and strict in-transaction serialization is required. Keep transactions short to reduce lock wait/deadlock risk.
-  - In all cases, scope by `tenant_id` and verify affected row counts for conditional writes.
-- Example:
-  - Bad:
-    ```python
-    # No tenant scope, no conflict detection, and no lock on a contested write path.
-    session.execute(update(WorkflowRun).where(WorkflowRun.id == run_id).values(status="cancelled"))
-    session.commit()  # silently overwrites concurrent updates
-    ```
-  - Good:
-    ```python
-    # 1) Optimistic lock (low contention, retry on conflict)
-    result = session.execute(
-        update(WorkflowRun)
-        .where(
-            WorkflowRun.id == run_id,
-            WorkflowRun.tenant_id == tenant_id,
-            WorkflowRun.version == expected_version,
-        )
-        .values(status="cancelled", version=WorkflowRun.version + 1)
-    )
-    if result.rowcount == 0:
-        raise WorkflowStateConflictError("stale version, retry")
-
-    # 2) Redis distributed lock (cross-worker critical section)
-    lock_name = f"workflow_run_lock:{tenant_id}:{run_id}"
-    with redis_client.lock(lock_name, timeout=20):
-        session.execute(
-            update(WorkflowRun)
-            .where(WorkflowRun.id == run_id, WorkflowRun.tenant_id == tenant_id)
-            .values(status="cancelled")
-        )
-        session.commit()
-
-    # 3) Pessimistic lock with SELECT ... FOR UPDATE (high contention)
-    run = session.execute(
-        select(WorkflowRun)
-        .where(WorkflowRun.id == run_id, WorkflowRun.tenant_id == tenant_id)
-        .with_for_update()
-    ).scalar_one()
-    run.status = "cancelled"
-    session.commit()
-    ```

+### Manual commands
+
+<details>
+<summary>Show manual setup and run steps</summary>
+
+These commands assume you start from the repository root.
+
+1. Start the docker-compose stack.
+
+   The backend requires middleware, including PostgreSQL, Redis, and Weaviate, which can be started together using `docker-compose`.
+
+   ```bash
+   cp docker/middleware.env.example docker/middleware.env
+   # Use mysql or another vector database profile if you are not using postgres/weaviate.
+   docker compose -f docker/docker-compose.middleware.yaml --profile postgresql --profile weaviate -p dify up -d
+   ```
+
+1. Copy env files.
+
+   ```bash
+   cp api/.env.example api/.env
+   cp web/.env.example web/.env.local
+   ```
+
+1. Install UV if needed.
+
+   ```bash
+   pip install uv
+   # Or on macOS
+   brew install uv
+   ```
+
+1. Install API dependencies.
+
+   ```bash
+   cd api
+   uv sync --group dev
+   ```
+
+1. Install web dependencies.
+
+   ```bash
+   cd web
+   pnpm install
+   cd ..
+   ```
+
+1. Start backend (runs migrations first, in a new terminal).
+
+   ```bash
+   cd api
+   uv run flask db upgrade
+   uv run flask run --host 0.0.0.0 --port=5001 --debug
+   ```
+
+1. Start Dify [web](../web) service (in a new terminal).
+
+   ```bash
+   cd web
+   pnpm dev:inspect
+   ```
+
+1. Set up your application by visiting `http://localhost:3000`.
+
+1. Optional: start the worker service (async tasks, in a new terminal).
+
+   ```bash
+   cd api
+   uv run celery -A app.celery worker -P threads -c 2 --loglevel INFO -Q dataset,priority_dataset,priority_pipeline,pipeline,mail,ops_trace,app_deletion,plugin,workflow_storage,conversation,workflow,schedule_poller,schedule_executor,triggered_workflow_dispatcher,trigger_refresh_executor,retention
+   ```
+
+1. Optional: start Celery Beat (scheduled tasks, in a new terminal).
+
+   ```bash

+   uv run celery -A app.celery beat
+   ```
