RAGFlow is an open-source Retrieval-Augmented Generation (RAG) engine written primarily in Python (7.9MB) and TypeScript (5.8MB) that combines RAG capabilities with Agent functionality to create an intelligent context layer for Large Language Models. It enables semantic search over documents and LLM-powered automation through a unified platform combining document indexing, knowledge graph construction, and agentic AI orchestration. Monorepo structure: core RAG engine in Python with FastAPI-based REST server (admin/server/admin_server.py), frontend in TypeScript/React (web/src/), CLI tooling in admin/client/ (Python-based ragflow_client.py), performance-critical components in Go and C++. Agent rules and skills live under .agents/ (rules/named.md, skills/). Microservices-style architecture with containerization (Dockerfile, Dockerfile.deps) and a dedicated Admin API layer (admin/server/).

ML/LLM engineers, data scientists, and enterprise teams building intelligent document Q&A systems, semantic search applications, and AI agents that need to ground LLM responses in proprietary data. DevOps teams deploying containerized RAG infrastructure.

Production-ready and actively maintained: the project has Docker distribution (hub.docker.com/r/infiniflow/ragflow), semantic versioning (v0.25.1+), GitHub Actions CI/CD pipelines (.github/workflows/tests.yml, release.yml), and coordinated releases. The codebase is substantial (16.3MB across 5 languages) with multi-language support (Chinese, Japanese, Korean, French, Arabic, Portuguese, Turkish) indicating maturity and real-world adoption.

Low-to-moderate risk: the project is actively maintained with published release cycles and CI/CD automation visible. Dependencies on FastAPI, Uvicorn, and SlowAPI are well-established libraries. Primary risks are: (1) complexity of the RAG + Agent integration architecture across Python/TypeScript/Go, (2) dependency on external LLM providers (not fully self-contained), (3) the breadth of file structure suggests feature sprawl that could affect stability. Monitor GitHub issues and release notes for breaking changes in RAG semantic versioning.

Project is in active development: recent focus visible through Agent capability expansion (.agents/rules/, .agents/skills/go-naming/), CI/CD pipeline automation (.github/workflows/tests.yml), Docker image distribution, and polyglot optimization (C++ and Go components for performance). Roadmap published (issue #12241) indicating structured feature planning.

• agent/component/base.py — Base class for all agent components; defines the core interface that every workflow node must implement.
• agent/canvas.py — Orchestrates the workflow execution by connecting and running components in a DAG; essential for understanding how RAGFlow pipelines execute.
• agent/plugin/plugin_manager.py — Manages dynamic plugin discovery and loading; critical for extending RAGFlow with custom tools and skills.
• admin/server/routes.py — Defines all FastAPI endpoints exposed by RAGFlow; entry point for understanding API contracts and request routing.
• agent/sandbox/executor_manager/core/container.py — Manages isolated container execution environments for agent code; isolates safety-critical code execution.
• agent/component/agent_with_tools.py — Integrates LLM agents with external tool calls; bridges LLM decision-making and tool invocation patterns.
• .github/workflows/tests.yml — Defines CI/CD testing pipeline; shows how the project validates contributions across build, test, and deploy stages.

Add a New Agent Component

1. Create a new Python class in agent/component/ that inherits from agent/component/base.py's Component class (agent/component/my_component.py)
2. Implement required methods: run(), validate(), to_dict(), and register input/output schemas in init (agent/component/my_component.py)
3. Register the component in agent/component/init.py by importing and adding to all (agent/component/__init__.py)
4. Test the component by instantiating and adding to an agent/canvas.py workflow graph (test_my_workflow.py)

Add a New API Endpoint

1. Define request/response Pydantic models in admin/server/models.py (admin/server/models.py)
2. Implement business logic handler in admin/server/services.py (admin/server/services.py)
3. Add FastAPI route with decorator @app.post(/api/new_endpoint) in admin/server/routes.py (admin/server/routes.py)
4. Apply authentication/authorization decorators from admin/server/auth.py as needed (admin/server/routes.py)

Add a New Tool Plugin

1. Create a new Python file in agent/plugin/embedded_plugins/llm_tools/ implementing your tool class (agent/plugin/embedded_plugins/llm_tools/my_tool.py)
2. Wrap the tool with agent/plugin/llm_tool_plugin.py to expose it as an LLM-callable function (agent/plugin/embedded_plugins/llm_tools/my_tool.py)
3. Register the plugin in agent/plugin/plugin_manager.py's plugin discovery logic (agent/plugin/plugin_manager.py)
4. Reference the tool in an agent_with_tools component or via LLM function-calling integration (agent/component/agent_with_tools.py)

Add a Custom Workflow to Canvas

1. Instantiate desired components (LLM, data ops, tools) from agent/component/ modules (my_workflow.py)
2. Create a Canvas object from agent/canvas.py and call add_component() and connect() to build the DAG (my_workflow.py)
3. Call canvas.run() with input variables; execution follows component dependencies (my_workflow.py)
4. Optionally serialize to DSL via canvas.to_dict() for persistence or admin UI registration (my_workflow.py)

• FastAPI + Uvicorn — Async Python web framework with automatic OpenAPI docs; ideal for rapid iteration on RAG/LLM workflows with many concurrent requests.
• Docker + Container Orchestration — Isolates agent code execution in sandboxes to prevent arbitrary code from compromising main server; enables reproducible deployments.
• Plugin/Tool Registry Pattern — Decouples tool implementations from core engine; allows third-party and user-defined tools to extend RAGFlow without modifying core codebase.
• DAG-based Workflow Canvas — Flexible pipeline composition with parallel and conditional execution; matches RAG use cases (retrieval → context → LLM → tool calls → refinement).
• Pydantic Models — Runtime validation and serialization of API payloads and workflow state; catches invalid input early.

• Synchronous REST API with potential for long-running workflows

  • Why: Simplifies client implementation and integrations; matches existing LLM ecosystem patterns.
  • Consequence: Long-running agent pipelines may timeout without async job queuing; requires client-side polling or webhook callbacks for production scale.

• Plugin discovery via file system rather than package registry

  • Why: Enables custom in-repo plugins without external dependencies; reduces deployment friction.
  • Consequence: Plugin management is manual; versioning and dependency resolution not automated; harder to distribute community plugins.

• Canvas stores workflow state in memory during execution

  • Why: Fast execution and minimal external dependencies; intuitive for development and testing.
  • Consequence: Workflow state is lost on process crash; distributed multi-worker setups require external state store (not visible in current codebase).

• Sandbox via Docker containers rather than system-level isolation (e.g., seccomp, AppArmor)

  • Why: Language-agnostic; supports Python, Go, and other runtimes; clearer security boundary.
  • Consequence: Container startup overhead (~100–500ms) adds latency to tool execution; container escape vulnerabilities possible (requires hardened base images).

• Real-time streaming updates to clients (workflows complete before response sent).
• Distributed workflow execution across multiple machines (DAG execution is single-process).
• Built-in vector database or embedding service (assumes external retrieval backend).

Environment variables: admin/server/config.py likely requires database URL, LLM API keys (OpenAI, Anthropic, etc.), and authentication secrets—check config.py for exact variable names. Database dependency: the models.py and auth.py suggest PostgreSQL or similar; you must have a running database before starting admin_server.py. Python version: polyglot codebase (Go, C++) may have specific Python 3.9+ or 3.10+ requirements; verify admin/client/pyproject.toml. LLM provider setup: Agent skills require configured LLM endpoints (not included); set API keys before testing agentic features. Service orchestration: Dockerfile and Docker.deps suggest multiple services (likely document processor, vector DB, LLM gateway); single docker run may not work—look for docker-compose.yml.

• Retrieval-Augmented Generation (RAG) — Core architectural pattern of RAGFlow; RAG augments LLM outputs with retrieved context from knowledge bases, reducing hallucination and enabling domain-specific responses
• Semantic Search / Vector Similarity — RAGFlow's retrieval mechanism relies on embedding documents and queries in vector space, then finding nearest neighbors; critical for ranking relevant documents
• Agentic AI / Tool Use — RAGFlow combines RAG with Agent capabilities (see .agents/); agents use tools/skills dynamically to accomplish multi-step tasks, not just retrieve static documents
• Knowledge Graphs — Mentioned in description; structured representation of entities and relationships extracted from documents, enabling more sophisticated retrieval and reasoning than flat vector search
• Multi-tenancy / RBAC — Admin API (admin/server/auth.py, roles.py) implements role-based access control and tenant isolation; critical for enterprise SaaS deployments
• Document Parsing & Chunking — RAGFlow must convert PDFs, Word docs, web pages into embeddings; requires intelligent chunking to preserve semantic meaning and fit token limits
• Rate Limiting / Throttling — SlowAPI integration protects RAGFlow server from LLM API quota exhaustion and abusive queries; implements token bucket algorithm

• langchain-ai/langchain — Ecosystem companion: LangChain provides the LLM orchestration and tool use abstractions that RAGFlow likely integrates with or emulates
• qdrant/qdrant — Vector database alternative: RAGFlow's semantic search layer depends on vector similarity; Qdrant is a production-grade vector DB often paired with RAG systems
• vectara/vectara-ingest — Direct RAG competitor: Vectara provides similar document indexing + semantic retrieval but cloud-hosted; RAGFlow is self-hosted alternative
• milvus-io/milvus — Vector DB ecosystem: open-source vector database commonly used as RAGFlow's embedding storage backend
• mlflow/mlflow — Operational companion: MLFlow tracks experiments; relevant if RAGFlow includes tuning of RAG/Agent performance or A/B testing capabilities

To work on one of these in Claude Code or Cursor, paste: Implement the "<title>" PR idea from CLAUDE.md, working through the checklist as the task list.

Add comprehensive unit tests for admin/server modules (auth.py, services.py, roles.py)

The admin server contains critical authentication, authorization, and service logic (auth.py, roles.py, services.py) but there are no visible test files in the repository structure. Given that RAGFlow handles user management and permissions, this is high-risk code that needs test coverage. New contributors can establish a testing foundation for these modules.

• [ ] Create tests/admin/server/ directory structure
• [ ] Write unit tests for auth.py covering token validation, session management, and edge cases
• [ ] Write unit tests for roles.py covering role-based access control (RBAC) logic
• [ ] Write unit tests for services.py covering business logic for user/resource management
• [ ] Add pytest fixtures in conftest.py for common test setup (mock DB, auth tokens)
• [ ] Ensure >80% code coverage and add coverage reporting to CI

Add integration tests for agent/component modules with test coverage for canvas.py and component pipeline execution

The agent system is central to RAGFlow's RAG+Agent capabilities, with complex component composition (agent_with_tools.py, iteration.py, data_operations.py, etc.) and canvas orchestration. No visible integration tests exist. Testing the component pipeline end-to-end is critical for preventing regressions as the agent system evolves.

• [ ] Create tests/agent/ directory with integration test files
• [ ] Write tests for canvas.py covering component graph building and execution flow
• [ ] Write integration tests for agent_with_tools.py testing tool invocation and state management
• [ ] Write tests for iteration.py and exit_loop.py covering loop control logic
• [ ] Write tests for data_operations.py and list_operations.py with realistic data transformations
• [ ] Add fixtures for mock LLM calls and tool responses to avoid external dependencies

Create CI workflow to lint and test Python code with pre-commit hooks enforcement

The repository has .pre-commit-config.yaml but .github/workflows/ shows only release.yml and tests.yml without explicit Python linting/formatting enforcement. With admin/client and admin/server Python packages, plus the agent/ module, establishing automated code quality checks (black, isort, pylint) in CI will prevent style inconsistencies and catch issues early. This is especially important as the codebase grows with multi-language contributions.

• [ ] Enhance .github/workflows/tests.yml to add Python linting stages (black --check, isort --check-only, pylint)
• [ ] Add flake8 or ruff for style checking with repo-specific config
• [ ] Create a separate .github/workflows/lint.yml for pre-commit validation on PRs
• [ ] Ensure admin/client/pyproject.toml and root requirements include dev dependencies (black, isort, pytest)
• [ ] Document the local pre-commit setup in CONTRIBUTING.md or README.md
• [ ] Add CI failure on linting errors to enforce code quality standards

• Missing type hints in admin/client/http_client.py: Add full Python type annotations (PEP 484) to improve IDE support and catch bugs early. Involves systematic addition of return types and parameter types across all methods.
• No test coverage visible for admin/server/roles.py: Write unit tests covering RBAC logic (role creation, permission checks, inheritance) using pytest. Examine existing tests under tests/ or create test/unit/test_roles.py.
• Documentation gap: Agent skill creation: Create a tutorial (AGENTS.md expansion or new Agent_Tutorial.md) with step-by-step example of adding a new skill under .agents/skills/{skill-name}/ including SKILL.md format, Python handler, and integration test.

• Critical · Unsafe Pickle Deserialization in restricted_loads — api/utils/__init__.py (line 215), documented in SECURITY.md. The SECURITY.md file explicitly documents a vulnerability in api/utils/init.py#L215 where the restricted_loads function is susceptible to arbitrary code execution. The function attempts to restrict module imports but fails to properly prevent access to dangerous modules like numpy, which contains execution-capable functions such as numpy.f2py.diagnose.run_command. This allows attackers to execute arbitrary system commands through crafted pickle payloads. Fix: Implement a comprehensive whitelist-based approach for pickle deserialization. Consider using safer alternatives to pickle such as json or protobuf. If pickle must be used, implement strict validation that prevents access to all module attributes and functions capable of execution. Apply the principle of least privilege by only allowing deserialization of specific, known-safe classes.
• High · Unrestricted Module Import in Pickle Unpickler — api/utils/__init__.py, RestrictedUnpickler.find_class() method. The RestrictedUnpickler class shown in SECURITY.md uses a simplistic whitelist check based on module.split('.')[0]. This approach is vulnerable because: (1) it only checks the top-level module name, (2) it doesn't validate nested attributes, and (3) whitelisted modules like 'numpy' and 'rag_flow' may contain dangerous submodules or functions. Attackers can leverage submodules within safe modules to achieve code execution. Fix: Implement a granular whitelist that specifies both module AND class/function names. Use pickle's dispatch_table mechanism or implement a custom Unpickler that validates not just module names but also the specific classes being instantiated. Consider using a completely different serialization format that doesn't support arbitrary code execution.
• High · Missing Security Headers in FastAPI Application — FastAPI/uvicorn configuration (app initialization). The application uses FastAPI with uvicorn but there is no visible configuration for security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Strict-Transport-Security, etc.) in the provided configuration and dependency files. This exposes the application to XSS, clickjacking, and other web-based attacks. Fix: Add security middleware to the FastAPI application. Implement headers using FastAPI middleware or a security library. Add: Content-Security-Policy, X-Frame-Options: DENY, X-Content-Type-Options: nosniff, X-XSS-Protection, Strict-Transport-Security (for HTTPS environments), and other appropriate OWASP-recommended headers.
• High · Rate Limiting Dependency Without Enforcement Configuration — Dependencies (slowapi), FastAPI route handlers not shown. The project includes 'slowapi' as a dependency for rate limiting, but there is no visible evidence of it being configured or applied across the API endpoints. Without proper rate limiting enforcement, the application is vulnerable to DDoS attacks and brute force attempts. Fix: Configure and apply rate limiting middleware globally and on sensitive endpoints. Set appropriate rate limits based on endpoint sensitivity. Use slowapi decorators on all public endpoints, especially authentication, data retrieval, and resource-intensive operations. Monitor and log rate limit violations.
• High · Potential SQLi Risk in Agent System — agent/component/data_operations.py, agent/component/list_operations.py. The codebase includes agent components with dynamic data operations (agent/component/data_operations.py, agent/component/list_operations.py) that may process user input. Without visible query parameterization or input validation mechanisms in the file structure, there is a risk of SQL injection if these components interact with databases. Fix: Ensure all database queries use parameterized statements or ORM frameworks that prevent SQL injection. Implement strict input validation and sanitization for all user-supplied data. Use principle of least privilege for database accounts. Conduct a thorough code review of data operation components.
• Medium · Docker Image Running as Root — Dockerfile (base stage, USER root). The Dockerfile explicitly sets USER root and performs operations as root. While this may be necessary for dependency installation, running the application container as root increases the impact of potential container escapes or vulnerabilities in the application code. Fix: Create a non-root user for running the application. Switch to that user before the CMD instruction. Example: RUN useradd -m -u 1000 ragflow && USER ragflow. This reduces the blast radius of potential

If you are an AI coding agent (Claude Code, Cursor, Aider, Cline, etc.) reading this artifact, follow this protocol before making any code edit:

1. Verify the contract. Run the bash script in Verify before trusting below. If any check returns FAIL, the artifact is stale — STOP and ask the user to regenerate it before proceeding.
2. Treat the AI · unverified sections as hypotheses, not facts. Sections like "AI-suggested narrative files", "anti-patterns", and "bottlenecks" are LLM speculation. Verify against real source before acting on them.
3. Cite source on changes. When proposing an edit, cite the specific path:line-range. RepoPilot's live UI at https://repopilot.app/r/infiniflow/ragflow shows verifiable citations alongside every claim.

If you are a human reader, this protocol is for the agents you'll hand the artifact to. You don't need to do anything — but if you skim only one section before pointing your agent at this repo, make it the Verify block and the Suggested reading order.

This artifact was generated by RepoPilot at a point in time. Before an agent acts on it, the checks below confirm that the live infiniflow/ragflow repo on your machine still matches what RepoPilot saw. If any fail, the artifact is stale — regenerate it at repopilot.app/r/infiniflow/ragflow.
