  "markdown": "# LangSmith Skills\n\n> **⚠️** — This project is in early development. APIs and skill content may change.\n\nAgent skills for observing and evaluating LLM applications with [LangSmith](https://smith.langchain.com/). Query traces, build evaluation datasets, and create custom evaluators — all from your coding agent.\n\n> Looking for skills to **build and improve** agents with LangChain, LangGraph, or Deep Agents? See [langchain-skills](https://github.com/langchain-ai/langchain-skills).\n\n## Supported Coding Agents\n\nThese skills can be installed for any agent supported by [`skills.sh`](https://skills.sh), including Claude Code, [Deep Agents CLI](https://docs.langchain.com/oss/python/deepagents/cli/overview), Cursor, Windsurf, Goose, and [many more](https://github.com/vercel-labs/skills).\n\n## Prerequisites\n\n- A [LangSmith API key](https://smith.langchain.com/)\n\n## Installation\n\n### Quick Install\n\nUsing [`npx skills`](https://github.com/vercel-labs/skills):\n\n**Local** (current project):\n```bash\nnpx skills add langchain-ai/langsmith-skills --skill '*' --yes\n```\n\n**Global** (all projects):\n```bash\nnpx skills add langchain-ai/langsmith-skills --skill '*' --yes --global\n```\n\nTo link skills to a specific agent (e.g. Claude Code):\n```bash\nnpx skills add langchain-ai/langsmith-skills --agent claude-code --skill '*' --yes --global\n```\n\n---\n\n### Claude Code Plugin\n\nInstall directly as a [Claude Code plugin](https://code.claude.com/docs/en/plugins):\n\n```bash\n/plugin marketplace add langchain-ai/langsmith-skills\n/plugin install langsmith-skills@langsmith-skills\n```\n\n---\n\n### Install Script (Claude Code & Deep Agents CLI only)\n\nAlternatively, clone the repo and use the install script:\n\n```bash\n# Install for Claude Code in current directory (default)\n./install.sh\n\n# Install for Claude Code in a specific project directory\n./install.sh ~/my-project\n\n# Install for Claude Code globally\n./install.sh --global\n\n# Install for DeepAgents CLI in a specific project directory\n./install.sh --deepagents ~/my-project\n\n# Install for DeepAgents CLI globally (includes agent persona)\n./install.sh --deepagents --global\n```\n\n| Flag / Argument | Description |\n|------|-------------|\n| `DIRECTORY` | Target project directory (default: current directory, ignored with `--global`) |\n| `--claude` | Install for Claude Code (default) |\n| `--deepagents` | Install for DeepAgents CLI |\n| `--global`, `-g` | Install globally instead of current directory |\n| `--force`, `-f` | Overwrite skills with same names as this package |\n| `--yes`, `-y` | Skip confirmation prompts |\n\n## Usage\n\nAfter installation, set your API keys:\n\n```bash\nexport LANGSMITH_API_KEY=<your-key>\nexport OPENAI_API_KEY=<your-key>      # For OpenAI models\nexport ANTHROPIC_API_KEY=<your-key>   # For Anthropic models\n```\n\nThen run your coding agent from the directory where you installed (for local installs) or from anywhere (for global installs).\n\n## Available Skills (3)\n\n### LangSmith\n- **langsmith-trace** - Query and export traces (includes helper scripts)\n- **langsmith-dataset** - Generate evaluation datasets from traces (includes helper scripts)\n- **langsmith-evaluator** - Create custom evaluators (includes helper scripts)\n\n**Note:** All skills include Python and TypeScript helper scripts for common operations.\n\n## Development\n\nAgent configuration lives in `config/`. To update an existing installation:\n\n```bash\n./install.sh --force\n```\n",
