Query and manage traces, prompts, datasets, and scores via the Langfuse API; look up documentation; do things with best practices in mind. |\n\n## Installation\n\n### Cursor Plugin\n\nInstall as a [Cursor plugin](https://cursor.com/docs/plugins):\n\n```\n/add-plugin langfuse\n```\n\n### skills CLI\n\nInstall via the [skills CLI](https://github.com/vercel-labs/skills):\n\n```bash\nnpx skills add langfuse/skills --skill \"langfuse\"\n```\n\n### Manual symlink\n\nClone this repo and symlink the skill into your agent's skills directory:\n\n```bash\ngit clone https://github.com/langfuse/skills.git /path/to/langfuse-skills\nln -s /path/to/langfuse-skills/skills/langfuse /path/to/skills-directory/langfuse\n```\n\n## Prerequisites\n\nYou need a Langfuse account ([cloud](https://cloud.langfuse.com) or [self-hosted](https://langfuse.com/docs/deployment/self-host)) and API keys:\n\n```bash\nexport LANGFUSE_PUBLIC_KEY=pk-lf-...\nexport LANGFUSE_SECRET_KEY=sk-lf-...\nexport LANGFUSE_BASE_URL=https://cloud.langfuse.com  # or https://us.cloud.langfuse.com, or self-hosted URL\n```\n\nAPI keys are found in your Langfuse project under **Settings > API Keys**.\n\n## Usage\n\nOnce installed, the agent will automatically use these skills when relevant — for example:\n\n- Setting up Langfuse tracing in a project\n- Setting up CI/CD experiment gates with `langfuse/experiment-action`\n- Auditing existing instrumentation\n- Preparing an application and Langfuse project for the v4 platform migration\n- Migrating prompts to Langfuse prompt management\n- Querying traces, prompts, or datasets via the API\n- Looking up Langfuse docs, SDK usage, or integration guides\n\n## Contributing\n\nWant to improve a skill or add a new one?
