-description: Use this agent when a feature branch is complete and ready to merge to main, and you need to create a changelog entry documenting the new feature or changes. This agent should be invoked proactively after significant feature work is completed and before merging.\n\nExamples:\n\n<example>\nContext: User has just completed implementing a new tracing visualization feature and the code has been reviewed.\nuser: "I've finished the trace timeline view feature. Can you help me prepare this for merge?"\nassistant: "Let me use the changelog-writer agent to create a changelog entry for this feature."\n<commentary>\nThe feature is complete and ready for merge, so we should use the changelog-writer agent to document it in the changelog.\n</commentary>\n</example>\n\n<example>\nContext: User mentions they're done with a feature implementation.\nuser: "The prompt versioning feature is done and tested. What's next?"\nassistant: "Great! Let me use the changelog-writer agent to create a changelog entry documenting this new feature before we merge."\n<commentary>\nSince the feature is complete, proactively use the changelog-writer agent to create documentation.\n</commentary>\n</example>\n\n<example>\nContext: User explicitly requests changelog creation.\nuser: "Can you create a changelog post for the new dataset export functionality?"\nassistant: "I'll use the changelog-writer agent to analyze the changes and create an appropriate changelog entry."\n<commentary>\nDirect request to create changelog, use the changelog-writer agent.\n</commentary>\n</example>

-You are an expert technical writer specializing in creating clear, user-focused changelog entries for developer tools and SaaS platforms. Your role is to document completed features in a way that helps users understand what's new, why it matters, and how to use it.
-
-## Your Process
-
-### Step 1: Understand the Changes
-1. Extract the Linear issue number from the current branch name (format: lfe-XXXX)
-2. Use the Linear MCP to fetch the issue details for additional context about the feature's purpose and requirements
-3. Compare the current branch to main using git diff to understand the scope of changes at a high level
-4. Identify the core feature or improvement that was implemented
-5. Determine which parts of the codebase were affected (frontend, backend, API, database, etc.)
-
-### Step 2: Study Recent Changelog Patterns
-1. Read 3-5 of the most recent changelog posts in `../langfuse-docs/pages/changelog`
-2. Analyze their structure, tone, and formatting conventions
-3. Note how they:
-   - Title features (concise, benefit-focused)
-   - Explain the "why" (user problems solved)
-   - Describe the "what" (feature capabilities)
-   - Link to relevant documentation
-   - Use images/screenshots
-   - Format code examples or technical details
-
-### Step 3: Identify Documentation Links
-1. Check if there is relevant documentation in `../langfuse-docs/pages` that relates to this feature
-2. If the feature is new, note that documentation may need to be created
-3. If the feature extends existing functionality, identify which docs pages should be referenced
-
-### Step 4: Draft the Changelog Entry
-Create a changelog post that includes:
-
-**Required Elements:**
-- **Title**: Clear, benefit-focused headline (not just the feature name)
-- **Date**: Use the current date in the format used by existing changelogs
-- **Summary**: 1-2 sentences explaining what changed and why it matters to users
-- **Description**: Detailed explanation of the feature, its capabilities, and use cases
-- **Documentation Links**: References to relevant docs pages (if applicable)
-
-**Style Guidelines:**
-- Write in second person ("you can now...")
-- Focus on user benefits, not implementation details
-- Be concise but complete
-- Use active voice
-- Include technical details only when they help users understand the feature
-- Match the tone and style of recent changelog entries
-
-**Formatting:**
-- Follow the exact file structure and frontmatter format of existing changelog posts
-- Use appropriate markdown formatting (headings, lists, code blocks, links)
-- Ensure proper spacing and readability
-
-### Step 5: Assess Visual Needs
-After drafting the changelog, explicitly tell the user:
-- Whether a screenshot or image would enhance understanding of this feature
-- What specific aspect should be captured in the screenshot (if applicable)
-- Where in the changelog the image should be placed
-
-## Quality Standards
-
-**Before presenting your changelog:**
-- Verify it follows the structure and style of recent entries
-- Ensure all links are correctly formatted
-- Check that technical terms match those used in the codebase and docs
-- Confirm the feature description is accurate based on the code changes
-- Validate that the user benefit is clear and compelling
-
-## Output Format
-
-Present your work in this order:
-1. Brief summary of what you learned from the branch comparison and Linear issue
-2. The complete changelog post content (ready to be saved as a new file)
-3. Recommendation on whether to add an image/screenshot and what it should show
-4. List of any documentation pages that should be referenced or created
-
-## Important Notes
-
-- The changelog lives in `../langfuse-docs/pages/changelog`
-- Always check the Linear issue via the branch name (lfe-XXXX format) for context
-- Compare against main branch to understand the full scope of changes
-- Study recent changelogs before writing to maintain consistency
-- Focus on user value, not technical implementation details
-- Be thorough in your analysis before drafting
-- If you're unsure about any aspect of the feature, ask clarifying questions before proceeding

-## Banner Height System
-
-When positioning elements with `sticky`, `fixed`, or `absolute` that have a global reference point (like `top-0`), **always use `top-banner-offset` instead of `top-0`**.
-
-### Why?
-The application can display system banners (payment issues, maintenance notices, etc.) that push content down. Using `top-banner-offset` ensures your positioned elements appear below the banner rather than being covered by it.
-
-### Usage
-
-**Bad:**
-```tsx
-<div className="fixed top-0 left-0 right-0">...</div>
-<div className="sticky top-0">...</div>
-<div className="absolute top-0">...</div>
-<div className="pt-0">...</div>
-```
-
-**Good:**
-```tsx
-<div className="fixed top-banner-offset left-0 right-0">...</div>
-<div className="sticky top-banner-offset">...</div>
-<div className="absolute top-banner-offset">...</div>
-<div className="pt-banner-offset">...</div>
-```
-
-### Additional Utilities
-
-- `h-screen-with-banner` / `min-h-screen-with-banner` - Use these for full-height containers that should account for banner space
-- `pt-banner-offset` - Use for padding-top to offset content below the banner
-- The system uses CSS variables `--banner-height` and `--banner-offset` defined in `web/src/styles/globals.css`
-- Banner components dynamically update `--banner-height` using ResizeObserver to track their actual rendered height, ensuring accuracy across all screen sizes
-
-### When NOT to use `top-banner-offset`
-
-- Elements positioned relative to their parent container (not globally)
-- Elements that should intentionally appear at the very top of the viewport
-- Elements inside modals/dialogs that are already z-indexed above banners

-- Check out other features to learn about the common structure.
-
-## API for frontend features
-
-- We use TRPC.io to power full-stack features of the Langfuse Frontend
-  - Entry point for all trpc routes: [root.ts](mdc:web/src/server/api/root.ts)

-## Components
-
-- We use Shadcn/ui
-  - Components in `@/src/components/ui`
-  - If a component is not installed yet, ask the user to install it for you
-- When creating new custom components that generalize, we add them with a generalizable naming to `@/src/components`
-
-## Styling

-- We use Tailwind CSS
-- We use a standard color palette which automatically handles light/dark mode, see [globals.css](mdc:web/src/styles/globals.css)

-
-- All public api routes are in /web/src/pages/api/public
-- New api routes should follow these guidelines:
-  - Use [withMiddlewares.ts](mdc:web/src/features/public-api/server/withMiddlewares.ts) as a wrapper
-  - Define types of api request and response in /web/src/features/public-api/types, use strict() for all zod objects
-  - Add end-to-end test, similar to [datasets-api.servertest.ts](mdc:web/src/__tests__/async/datasets-api.servertest.ts)
-  - Add fern configuration in /fern, learn more about structure here: https://buildwithfern.com/learn/api-definition/fern/overview
-  - Prompt user to regenerate the OpenAPI spec via the fern CLI
-  - Pagination starts at 1, query typing defined in publicApiPaginationZod, return meta in paginationMetaResponseZod
-- For tests, please look at [this directory](mdc:web/src/__tests__/async/) for examples

-# Codex Guidelines for Langfuse
-
-Langfuse is an **open source LLM engineering** platform for developing, monitoring, evaluating and debugging AI applications. See the README for more details.
-
-## Linting
-- Run `pnpm run lint` to lint all packages.
-- Fix issues automatically with `pnpm run lint:fix`.
-
-## Tests
-- Codex cannot run the test suite because it depends on Docker-based infrastructure that is unavailable in this environment.
-- When writing tests, focus on decoupling each `it` or `test` block to ensure that they can run independently and concurrently. Tests must never depend on the action or outcome of previous or subsequent tests.
-- When writing tests, especially in the __tests__/async directory, ensure that you avoid `pruneDatabase` calls.
-
-## Cursor Rules
-- Additional folder-specific rules live in `.cursor/rules/`.
-
-## Commits
-- Follow [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) when crafting commit messages.

-## Project Overview
-
-Langfuse is an open-source LLM engineering platform that helps teams collaboratively develop, monitor, evaluate, and debug AI applications.
-The main feature areas are tracing, evals and prompt management. Langfuse consists of the web application (this repo), documentation, python SDK and javascript/typescript SDK.
-This repo contains the web application, worker, and supporting packages but notably not the JS nor Python client SDKs.
-
-## Repository Structure
-High level structure. There are more folders (eg for hooks etc).
-```

-
-## Repository Architecture
-This is a **pnpm + Turbo monorepo** with the following key packages:
-
-### Core Applications
-- **`/web/`** - Next.js 14 application (Pages Router) providing both frontend UI and backend APIs
-- **`/worker/`** - Express.js background job processing server
-- **`/packages/shared/`** - Shared database schema, types, and utilities
-
-### Supporting Packages
-- **`/ee/`** - Enterprise Edition features (separate licensing)
-- **`/packages/config-eslint/`** - Shared ESLint configuration
-- **`/packages/config-typescript/`** - Shared TypeScript configuration
-
-## Development Commands
-
-### Development
-```sh
-pnpm i               # Install dependencies
-pnpm run dev         # Start all services (web + worker)
-pnpm run dev:web     # Web app only (localhost:3000) - **used in most cases!**
-pnpm run dev:worker  # Worker only
-pnpm run dx          # Full initial setup: install deps, reset DBs, resets node modules, seed data, start dev. USE SPARINGLY AS IT WIPES THE DATABASE & node_modules
-```
-
-### Database Management
-database commands are to be run in the `packages/shared/` folder.
-```sh
-pnpm run db:generate       # Build prisma models
-pnpm run db:migrate        # Run Prisma migrations
-pnpm run db:reset          # Reset and reseed databases
-pnpm run db:seed           # Seed with example data
-```
-
-### Infrastructure
-```sh
-pnpm run infra:dev:up      # Start Docker services (PostgreSQL, ClickHouse, Redis, MinIO)
-pnpm run infra:dev:down    # Stop Docker services
-```
-
-### Building
-```sh
-pnpm --filter=PACKAGE_NAME run build  # Runs the build command, will show real typescript errors etc.
-```
-
-### Testing in Web Package
-The web package uses JEST for unit tests.
-Depending on the file location (sync, async)
-`web` related tests must go into the `web/src/__tests__/` folder.
-```sh
-pnpm test-sync --testPathPattern="$FILE_LOCATION_PATTERN" --testNamePattern="$TEST_NAME_PATTERN"
-# For tests in the async folder:
-pnpm test -- --testPathPattern="$FILE_LOCATION_PATTERN" --testNamePattern="$TEST_NAME_PATTERN"
-# For client tests:
-pnpm test-client --testPathPattern="buildStepData" --testNamePattern="buildStepData"
-```
-
-### Testing in the Worker Package
-The worker uses `vitest` for unit tests.
-```sh
-pnpm run test --filter=worker -- $TEST_FILE_NAME -t "$TEST_NAME"
-```
-
-### Utilities
-```bash
-pnpm run format            # Format code across entire project
-pnpm run nuke              # Remove all node_modules, build files, wipe database, docker containers. **USE WITH CAUTION**
-```
-
-## Technology Stack
-
-### Web Application (`/web/`)
-- **Framework**: Next.js 14 (Pages Router)
-- **APIs**: tRPC (type-safe client-server communication) + REST APIs for public access
-- **Authentication**: NextAuth.js/Auth.js
-- **Database**: Prisma ORM with PostgreSQL
-- **Analytics Database**: ClickHouse (high-volume trace data)
-- **Validation**: Zod schemas, we use zodv4 (always import from `zod/v4`)
-- **Styling**: Tailwind CSS with CSS variables for theming
-- **Components**: shadcn/ui (Radix UI primitives)
-- **State Management**: TanStack Query (React Query) + tRPC
-- **Charts**: Tremor, Recharts
-
-### Worker Application (`/worker/`)
-- **Framework**: Express.js
-- **Queue System**: BullMQ with Redis
-- **Purpose**: Async processing (data ingestion, evaluations, exports, integrations)
-
-### Infrastructure
-- **Primary Database**: PostgreSQL (via Prisma ORM)
-- **Analytics Database**: ClickHouse
-- **Cache/Queues**: Redis
-- **Blob Storage**: MinIO/S3
-
-## Development Guidelines
-
-### Frontend Features
-- All new features go in `/web/src/features/[feature-name]/`
-- Use tRPC for full-stack features (entry point: `web/src/server/api/root.ts`)
-- Follow existing feature structure for consistency
-- Use shadcn/ui components from `@/src/components/ui`
-- Custom reusable components go in `@/src/components`
-
-### Public API Development
-- All public API routes in `/web/src/pages/api/public`
-- Use `withMiddlewares.ts` wrapper
-- Define types in `/web/src/features/public-api/types` with strict Zod v4 objects
-- Add end-to-end tests (see `datasets-api.servertest.ts`)
-- Manually update Fern API specs in `/fern/`, then regenerate OpenAPI spec via Fern CLI
-
-### Authorization & RBAC
-- Check `/web/src/features/rbac/README.md` for authorization patterns
-- Implement proper entitlements checking (see `/web/src/features/entitlements/README.md`)
-
-### Database
-- **Dual database system**: PostgreSQL (primary) + ClickHouse (analytics)
-- Use `golang-migrate` CLI for database migrations
-- All database operations go through Prisma ORM for PostgreSQL
-- Foreign key relationships may not be enforced in schema to allow unordered ingestion
-
-### Testing
-- Jest for API tests, Playwright for E2E tests
-- For backend/API changes, tests must pass before pushes
-- Add tests for new API endpoints and features
-- When writing tests, focus on decoupling each `it` or `test` block to ensure that they can run independently and concurrently. Tests must never depend on the action or outcome of previous or subsequent tests.
-- When writing tests, especially in the __tests__/async directory, ensure that you avoid `pruneDatabase` calls.
-
-### Code Conventions
-- **Pages Router** (not App Router)
-- Follow conventional commits on main branch
-- Use CSS variables for theming (supports auto dark/light mode)
-- TypeScript throughout
-- Zod v4 for all input validation
-
-## Environment Setup
-
-- **Node.js**: Version 24 (specified in `.nvmrc`)
-- **Package Manager**: pnpm v9.5.0
-- **Database Dependencies**: Docker for local PostgreSQL, ClickHouse, Redis, MinIO
-- **Environment**: Copy `.env.dev.example` to `.env`
-
-## Login for Development
-
-When running locally with seed data:
-- Username: `demo@langfuse.com`
-- Password: `password`
-- Demo project URL: `http://localhost:3000/project/7a88fb47-b4e2-43b8-a06c-a5ce950dc53a`
-
-## Linear MCP
-To get a project, use the `get_project` capability with the full project name as it is in the title.
-- bad: message-placeholder-in-chat-messages-2beb6f02ec48
-- good: Message placeholder in chat messages
-
-## Front-end Tips
-
-### Window Location Handling
-- Whenever you want to use or do use window.location..., ensure that you also add proper handling for a custom basePath
-
-## TypeScript Best Practices
-- In TypeScript, if possible, don't use the `any` type
-
-## General Coding Guidelines
-- For easier code reviews, prefer not to move functions etc around within a file unless necessary or instructed to do so
-
-## Development Tips
-- Before trying to build the package, try running the linter once first

 On the main branch, we adhere to the best practices of [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/). All pull requests and branches are squash-merged to maintain a clean and readable history. This approach ensures the addition of a conventional commit message when merging contributions.
 
-## Running Unit Tests
+## Test the public API
 
-All tests run in the CI and must pass before merging.
-All tests run against a running langfuse instance and **write/delete real data from the database**.
+The API is tested using Jest. With the development server running, you can run the tests with:
 
-### Test Database Setup
-
-Per default, the tests use the local development database. Therefore, wiping your data in the process.
-For proper test isolation, create a `.env.test` file in the root directory:
+Run all
 
 ```bash
-cp .env.test.example .env.test
+npm run test
 ```
 
-Then, a different PostgreSQL and Redis are used for the tests.
-The `.env.test` file only overrides the set values and falls back on `.env` for all undefined values.
+Run interactively in watch mode
 
-- **PostgreSQL**: Uses separate `langfuse_test` database for isolation
-- **ClickHouse**: Uses shared `default` database for now
-- **Redis**: Uses database 1 instead of 0 for isolation (Redis data is not cleaned between tests)
-
-Tests automatically create the PostgreSQL test database if it doesn't exist and clean up data between runs.
-
-### Tests in the `web` package (public API)
-
-We're using Jest with in the `web` package. Therefore, if you want to provide an argument to the test runner, do it directly without an intermittent `--`.
-
-There are three types of unit tests:
-
-- `test-sync`
-- `test` (for async folder tests)
-- `test-client`
-
-To run a specific test, for example the test: `"should handle special characters in prompt names"` in `prompts.v2.servertest.ts`, run:
-
-```sh
-cd web  # or with --filter=web

-## ✨ 核心特性
-
-![Langfuse 概览](https://langfuse.com/images/docs/github-readme/github-feature-overview.png)
-
-- [LLM 应用可观察性](https://langfuse.com/docs/tracing)：为你的应用插入仪表代码，并开始将追踪数据传送到 Langfuse，从而追踪 LLM 调用及应用中其他相关逻辑（如检索、嵌入或代理操作）。检查并调试复杂日志及用户会话。试试互动的 [演示](https://langfuse.com/docs/demo) 看看效果。
-- [提示管理](https://langfuse.com/docs/prompt-management/get-started) 帮助你集中管理、版本控制并协作迭代提示。得益于服务器和客户端的高效缓存，你可以在不增加延迟的情况下反复迭代提示。
-
-- [评估](https://langfuse.com/docs/evaluation/overview) 是 LLM 应用开发流程的关键组成部分，Langfuse 能够满足你的多样需求。它支持 LLM 作为"裁判"、用户反馈收集、手动标注以及通过 API/SDK 实现自定义评估流程。
-
-- [数据集](https://langfuse.com/docs/evaluation/dataset-runs/datasets) 为评估你的 LLM 应用提供测试集和基准。它们支持持续改进、部署前测试、结构化实验、灵活评估，并能与 LangChain、LlamaIndex 等框架无缝整合。
-
-- [LLM 试玩平台](https://langfuse.com/docs/playground) 是用于测试和迭代提示及模型配置的工具，缩短反馈周期，加速开发。当你在追踪中发现异常结果时，可以直接跳转至试玩平台进行调整。
-
-- [综合 API](https://langfuse.com/docs/api)：Langfuse 常用于驱动定制化的 LLMOps 工作流程，同时利用 Langfuse 提供的构建模块和 API。我们提供 OpenAPI 规格、Postman 集合以及针对 Python 和 JS/TS 的类型化 SDK。

-## 🚀 快速入门
-
-为你的应用增加仪表代码，并开始将追踪数据上传到 Langfuse，从而记录 LLM 调用及应用中其他相关逻辑（如检索、嵌入或代理操作）。
-
-### 1️⃣ 创建新项目
-
-1. [创建 Langfuse 账户](https://cloud.langfuse.com/auth/sign-up) 或 [自托管](https://langfuse.com/self-hosting)
-2. 创建一个新项目
-3. 在项目设置中创建新的 API 凭证
-
-### 2️⃣ 记录你的第一个 LLM 调用
-
-使用 [<code>@observe()</code> 装饰器](https://langfuse.com/docs/sdk/python/decorators) 可轻松跟踪任何 Python LLM 应用。在本快速入门中，我们还使用了 Langfuse 的 [OpenAI 集成](https://langfuse.com/integrations/model-providers/openai-py) 来自动捕获所有模型参数。
-
-> [!提示]
-> 不使用 OpenAI？请访问 [我们的文档](https://langfuse.com/docs/get-started#log-your-first-llm-call-to-langfuse) 了解如何记录其他模型和框架。
-
-安装依赖：
-
-```bash
-pip install langfuse openai
-```
-
-配置环境变量（创建名为 **.env** 的文件）：
-
-```bash:.env
-LANGFUSE_SECRET_KEY="sk-lf-..."
-LANGFUSE_PUBLIC_KEY="pk-lf-..."
-LANGFUSE_BASE_URL="https://cloud.langfuse.com" # 🇪🇺 欧盟区域
-# LANGFUSE_BASE_URL="https://us.cloud.langfuse.com" # 🇺🇸 美洲区域
-```
-
-创建示例代码（文件名：**main.py**）：
-
-```python:main.py
-from langfuse import observe
-from langfuse.openai import openai  # OpenAI 集成
-
-@observe()
-def story():
-    return openai.chat.completions.create(
-        model="gpt-4o",
-        messages=[{"role": "user", "content": "What is Langfuse?"}],
-    ).choices[0].message.content
-
-@observe()
-def main():
-    return story()
-
-main()
-```
-
-### 3️⃣ 在 Langfuse 中查看追踪记录
-
-在 Langfuse 中查看你的语言模型调用及其他应用逻辑。

-## 🚀 クイックスタート
-
-アプリケーションにインストゥルメンテーションを導入し、LLM呼び出しやリトリーバル、埋め込み、エージェントアクションなどの動作をLangfuseに記録しましょう。  
-複雑なログやユーザーセッションの解析・デバッグが可能になります。
-
-### 1️⃣ 新規プロジェクトの作成
-
-1. [Langfuseアカウント作成](https://cloud.langfuse.com/auth/sign-up) または [セルフホスト](https://langfuse.com/self-hosting)
-2. 新規プロジェクトを作成
-3. プロジェクト設定で新しいAPIクレデンシャルを作成
-
-### 2️⃣ 初めてのLLM呼び出しのログ記録
-
-[`@observe()` デコレーター](https://langfuse.com/docs/sdk/python/decorators)を利用することで、任意のPython製LLMアプリケーションのトレースが簡単に行えます。  
-このクイックスタートでは、Langfuseの[OpenAI統合](https://langfuse.com/integrations/model-providers/openai-py)を使用して、全てのモデルパラメータを自動で取得します。
-
-> [!TIP]

-## ✨ 주요 기능
-
-![Langfuse Overview](https://langfuse.com/images/docs/github-readme/github-feature-overview.png)
-
-- **LLM 애플리케이션 관측**  
-  앱에 계측(instrumentation)을 추가하여 Langfuse로 trace 데이터를 수집함으로써, 검색, 임베딩, 또는 에이전트 동작과 같은 LLM 호출 및 기타 관련 로직을 추적할 수 있습니다. 복잡한 로그와 사용자 세션을 확인 및 디버깅 해보세요. 인터랙티브 데모를 통해 실제 작동 예를 확인할 수 있습니다.
-
-- **프롬프트 관리**  
-  프롬프트를 중앙에서 관리하고 버전 관리하며 협업으로 수정할 수 있도록 도와줍니다. 서버와 클라이언트 측의 강력한 캐싱 덕분에 애플리케이션에 지연(latency)을 추가하지 않고도 프롬프트를 반복 개선할 수 있습니다.
-
-- **평가**  
-  LLM 애플리케이션 개발 워크플로우에서 핵심적인 역할을 하며, Langfuse는 여러분의 필요에 맞게 유연하게 대응합니다. LLM을 심사자로 활용하는 기능, 사용자 피드백 수집, 수동 라벨링 및 API/SDK를 통한 맞춤 평가 파이프라인을 지원합니다.
-
-- **데이터셋**  
-  LLM 애플리케이션 평가를 위한 테스트 세트와 벤치마크를 제공하여, 지속적인 개선, 배포 전 테스트, 구조화된 실험, 유연한 평가 및 LangChain과 LlamaIndex와 같은 프레임워크와의 원활한 통합을 지원합니다.
-
-- **LLM 플레이그라운드**  
-  프롬프트와 모델 구성에 대해 테스트 및 반복 개선할 수 있는 도구로, 피드백 루프를 단축하여 개발 속도를 높여줍니다. trace에서 이상한 결과가 발생하면 플레이그라운드로 바로 이동해 개선할 수 있습니다.
-
-- **종합 API**  
-  Langfuse는 API를 통해 제공되는 구성 요소들을 활용하여 맞춤형 LLMOps 워크플로우를 강화하는 데 자주 사용됩니다. OpenAPI 명세, Postman 컬렉션, Python 및 JS/TS용 타입드 SDK가 제공됩니다.

-## 🚀 빠른 시작
-
-앱에 계측을 추가하고 Langfuse에 trace 데이터를 수집하여, LLM 호출 및 검색, 임베딩, 에이전트 동작과 같은 애플리케이션 로직을 추적해보세요. 복잡한 로그와 사용자 세션을 확인하여 디버깅할 수 있습니다.
-
-### 1️⃣ 새 프로젝트 생성
-
-1. [Langfuse 계정 생성](https://cloud.langfuse.com/auth/sign-up) 또는 [셀프 호스트](https://langfuse.com/self-hosting)
-2. 새 프로젝트를 생성합니다.
-3. 프로젝트 설정에서 새로운 API 자격 증명을 생성합니다.
-
-### 2️⃣ 첫 번째 LLM 호출 기록하기
-
-[`@observe()` 데코레이터](https://langfuse.com/docs/sdk/python/decorators)를 사용하면 Python LLM 애플리케이션의 추적이 매우 간편해집니다. 이 빠른 시작 예제에서는 Langfuse [OpenAI 통합](https://langfuse.com/integrations/model-providers/openai-py)을 사용하여 모든 모델 파라미터를 자동으로 캡처합니다.
-
-> [!TIP]
-> OpenAI를 사용하지 않으시다면, 다른 모델 및 프레임워크의 로그 기록 방법은 [문서](https://langfuse.com/docs/get-started#log-your-first-llm-call-to-langfuse)를 참조하세요.

-```bash
-pip install langfuse openai

-## 🔒 보안 & 개인정보 보호
-
-우리는 데이터 보안과 개인정보 보호를 매우 중요하게 생각합니다. 자세한 내용은 [Security and Privacy](https://langfuse.com/security) 페이지를 참조하세요.
-
-### 텔레메트리
-
-기본적으로 Langfuse는 자체 호스팅 인스턴스의 기본 사용 통계를 중앙 서버(PostHog)로 자동 보고합니다.
-
-이를 통해:
-
-1. Langfuse가 어떻게 사용되는지 이해하고, 가장 관련성 높은 기능을 개선할 수 있습니다.
-2. 내부 및 외부(예: 자금 조달) 보고를 위한 전체 사용량을 추적할 수 있습니다.
-
-수집된 데이터는 제3자와 공유되지 않으며 민감한 정보를 포함하지 않습니다. 이에 대해 매우 투명하게 공개하고 있으며, 수집되는 정확한 데이터는 [여기](/web/src/features/telemetry/index.ts)에서 확인할 수 있습니다.
-
-환경 변수 `TELEMETRY_ENABLED=false`를 설정하여 옵트아웃할 수 있습니다.

+### Develop
 
-## ✨ Core Features
+- **LLM Observability:** Instrument your app and start ingesting traces to Langfuse ([Quickstart](https://langfuse.com/docs/get-started), [Integrations](https://langfuse.com/docs/integrations) [Tracing](https://langfuse.com/docs/tracing))
+- **Langfuse UI:** Inspect and debug complex logs ([Demo](https://langfuse.com/docs/demo), [Tracing](https://langfuse.com/docs/tracing))
+- **Prompt Management:** Manage, version and deploy prompts from within Langfuse ([Prompt Management](https://langfuse.com/docs/prompts/get-started))
+- **Prompt Engineering:** Test and iterate on your prompts with the [LLM Playground](https://langfuse.com/docs/playground)
 
-<img width="4856" height="1944" alt="Langfuse Overview" src="https://github.com/user-attachments/assets/5dac68ef-d546-49fb-b06f-cfafc19282e3" />
+### Monitor
 
-- [LLM Application Observability](https://langfuse.com/docs/tracing): Instrument your app and start ingesting traces to Langfuse, thereby tracking LLM calls and other relevant logic in your app such as retrieval, embedding, or agent actions. Inspect and debug complex logs and user sessions. Try the interactive [demo](https://langfuse.com/docs/demo) to see this in action.
+- **LLM Analytics:** Track metrics (cost, latency, quality) and gain insights from dashboards & data exports ([Analytics](https://langfuse.com/docs/analytics))
+- **LLM Evaluations:** Collect and calculate scores for your LLM completions ([Scores & Evaluations](https://langfuse.com/docs/scores))
+  - Run ([Model-based evaluations](https://langfuse.com/docs/scores/model-based-evals)) and LLM-as-a-Judge within Langfuse
+  - Collect user feedback ([User Feedback](https://langfuse.com/docs/scores/user-feedback))
+  - Manually score LLM outputs in Langfuse ([Manual Scores](https://langfuse.com/docs/scores/manually))
 
-- [Prompt Management](https://langfuse.com/docs/prompt-management/get-started) helps you centrally manage, version control, and collaboratively iterate on your prompts. Thanks to strong caching on server and client side, you can iterate on prompts without adding latency to your application.
+### Test
 
-- [Evaluations](https://langfuse.com/docs/evaluation/overview) are key to the LLM application development workflow, and Langfuse adapts to your needs. It supports LLM-as-a-judge, user feedback collection, manual labeling, and custom evaluation pipelines via APIs/SDKs.
+- **Experiments:** Track and test app behaviour before deploying a new version
+  - Datasets let you test expected in and output pairs and benchmark performance before deploying ([Datasets](https://langfuse.com/docs/datasets))
+  - Track versions and releases in your application ([Experimentation](https://langfuse.com/docs/experimentation), [Prompt Management](https://langfuse.com/docs/prompts))
 
-- [Datasets](https://langfuse.com/docs/evaluation/dataset-runs/datasets) enable test sets and benchmarks for evaluating your LLM application. They support continuous improvement, pre-deployment testing, structured experiments, flexible evaluation, and seamless integration with frameworks like LangChain and LlamaIndex.
-
-- [LLM Playground](https://langfuse.com/docs/playground) is a tool for testing and iterating on your prompts and model configurations, shortening the feedback loop and accelerating development. When you see a bad result in tracing, you can directly jump to the playground to iterate on it.
-
-- [Comprehensive API](https://langfuse.com/docs/api): Langfuse is frequently used to power bespoke LLMOps workflows while using the building blocks provided by Langfuse via the API. OpenAPI spec, Postman collection, and typed SDKs for Python, JS/TS are available.

+### Support and feedback
 
-### 2️⃣ Log your first LLM call
+In order of preference the best way to communicate with us:
 
-The [`@observe()` decorator](https://langfuse.com/docs/sdk/python/decorators) makes it easy to trace any Python LLM application. In this quickstart we also use the Langfuse [OpenAI integration](https://langfuse.com/integrations/model-providers/openai-py) to automatically capture all model parameters.
+- [GitHub Discussions](https://github.com/orgs/langfuse/discussions) (preferred): Contribute [ideas](https://langfuse.com/ideas), [support requests](https://langfuse.com/gh-support) and [report bugs](https://langfuse.com/issues)

-# Code Review Instructions
-
-## Database Migrations
-
-### ClickHouse
-
-- ClickHouse migrations in the `packages/shared/clickhouse/migrations/clustered` directory should include `ON CLUSTER default` and should use `Replicated` merge tree table types.
-  - E.g. `ReplacingMergeTree` is likely an error while `ReplicatedReplacingMergeTree` would be correct in most cases.
-- ClickHouse migrations in the `packages/shared/clickhouse/migrations/unclustered` directory must not include `ON CLUSTER` statements and must not use `Replicated` merge tree table types.
-- Migrations in `packages/shared/clickhouse/migrations/clustered` should match their counterparts in `packages/shared/clickhouse/migrations/unclustered` aside from the restrictions listed above.
-- When adding new indexes on ClickHouse, ensure that there is a corresponding `MATERIALIZE INDEX` statement in the same migration. The materialization can use `SETTINGS mutations_sync = 2` if they operate on smaller tables, but may timeout otherwise.
-
-### Postgres
-
-- Most `schema.prisma` changes should produce a change in `packages/shared/prisma/migrations`.
-
-### Environment Variables
-
-- Environment variables should be imported from the `env.mjs/ts` file of the respective package and not from `process.env.*` to ensure validation and typing.
-
-## Redis Invocations
-
-- Highlight usage of `redis.call` invocations. Those may have suboptimal redis cluster routing and will raise errors. Instead, use the native call patterns.
-  Example: `await redis?.call("SET", key, "1", "NX", "EX", TTLSeconds);` should use `await redis?.set(key, "1", "EX", TTLSeconds, "NX");` instead.
-
-## Langfuse Cloud
-
-- When attempting to confirm if the current environment is Langfuse Cloud in the frontend, use the `useLangfuseCloudRegion` hook and never environment variables directly.
-
-## Banner Height System
-
-- Use `top-banner-offset` instead of `top-0` for any elements that are positioned `sticky`, `fixed`, or `absolute` with a global reference point (e.g., `top-0`). This ensures proper spacing when system banners (payment, maintenance, etc.) are displayed.
-- The banner height is managed through CSS variables (`--banner-height` and `--banner-offset`) defined in `web/src/styles/globals.css`.
-- Banner components (like PaymentBanner) dynamically update `--banner-height` using ResizeObserver to track their actual height, ensuring accurate positioning even when banners resize (e.g., on mobile wrapping).
-- Available Tailwind utilities:
-  - `top-banner-offset` / `pt-banner-offset` - For sticky/fixed/absolute positioning and padding
-  - `h-screen-with-banner` / `min-h-screen-with-banner` - For full-height containers accounting for banners
-
-## JavaScript / TypeScript Style
-- use concat instead of spread to avoid stack overflow with large arrays

-        Internally, we refer to this as the "event envelope" as it tells us something about the event but not the trace.
-        We use the event id within this envelope to deduplicate messages to avoid processing the same event twice, i.e. the event id should be unique per request.
-        The event.body.id is the ID of the actual trace and will be used for updates and will be visible within the Langfuse App.
-        I.e. if you want to update a trace, you'd use the same body id, but separate event IDs.
