It supercharges your coding assistant (Kilocode, Claude Code, Cursor, etc), making it an expert in any agent framework you choose (Agno, Mastra, LangGraph etc) and all their best practices. It's the best way to start any new agent project.  The Better Agent Structure and generated AGENTS.md ensures industry best practices, making your agent ready for production: - [Scenario](https://github.com/langwatch/scenario) agent tests written for every feature to ensure agent behaviour - Versioning of the prompts for collaboration - Evaluation notebooks for measuring specific prompts performance - Already instrumented for full observability - Standardization of structure for better project maintainability ## The Better Agent Structure ``` my-agent-project/ ├── app/ (or src/) # The actual agent code, according to the chosen framework ├── tests/ │ ├── evaluations/ # Jupyter notebooks for evaluations │ │ └── example_eval.ipynb │ └── scenarios/ # End-to-end scenario tests │ └── example_scenario.test.{py,ts} ├── prompts/ # Versioned prompt files for team collaboration │ └── sample_prompt.yaml ├── prompts.json # Prompt registry ├── .mcp.json # MCP server configuration ├── AGENTS.md # Development guidelines ├── .env # Environment variables └── .gitignore ``` The structure and guidelines on `AGENTS.md` ensure every new feature required for the coding assistant is properly tested, evaluated, and that the prompts are versioned. The `.mcp.json` comes with all the right MCPs set up so you coding assistant becomes an expert in your framework of choice and in writing Scenario tests for your agent. [`scenarios/`](https://github.com/langwatch/scenario) tests guarantee the agent behaves as expected, which simulates a conversation with the agent making sure it does what expected. [`evaluations/`](https://docs.langwatch.ai/llm-evaluation/offline/code/evaluation-api) notebooks holds dataset and notebooks for evaluating pieces of your agent pipeline such as a RAG or classification tasks it must do Finally, [`prompts/`](https://docs.langwatch.ai/prompt-management/cli) hold all your versioned prompts in yaml format, synced and controlled by `prompts.json`, to allow for playground and team collaboration. ## Getting Started ### Installation ```bash npm install -g @langwatch/better-agents ``` Or use with npx: ```bash npx @langwatch/better-agents init my-agent-project ``` ### Initialize a new project ```bash # In current directory better-agents init . # In a new directory better-agents init my-awesome-agent ``` The CLI will guide you through selecting your programming language, agent framework, coding assistant, LLM provider, and API keys. ## Documentation - **[Getting Started](docs/GETTING-STARTED.md)** - Quick start guide (2 minutes) - **[Walkthrough](docs/WALKTHROUGH.md)** - Detailed step-by-step guide - **[Project Structure](docs/STRUCTURE.md)** - Understanding the Better Agent structure - **[Features](docs/FEATURES.md)** - Key features and capabilities - **[Usage](docs/USAGE.md)** - CLI usage and examples - **[Philosophy](docs/PHILOSOPHY.md)** - Agent Testing Pyramid approach - **[Contributing](docs/CONTRIBUTING.md)** - How to contribute to Better Agents - **[Changelog](CHANGELOG.md)** - Version history ## Requirements - Node.js 22+ - npm or pnpm - A coding assistant (one of the following): - [Claude Code](https://docs.anthropic.com/en/docs/agents-and-tools/claude-code-agent) (`claude` CLI) - [Cursor](https://www.cursor.com/) - [Antigravity](https://antigravity.google/) (`agy`) - [Kilocode CLI](https://www.kilocode.ai/) (`kilocode`) - API Keys: - LangWatch API key (get one at https://app.langwatch.ai/authorize) - Your chosen LLM Provider API key - Telemetry (optional): - Anonymous usage telemetry is enabled by default. - To opt out, set the environment variable: ```bash BETTER_AGENTS_TELEMETRY=0 ``` ## Resources - [LangWatch](https://langwatch.ai) - [Scenario Documentation](https://scenario.langwatch.ai/) - [Agent Testing Pyramid](https://scenario.langwatch.ai/best-practices/the-agent-testing-pyramid) - [Agno](https://agno.com) - [Mastra](https://mastra.ai) - [Discord](https://discord.com/invite/kT4PhDS2gH) ## License MIT --- Built with ❤️ by the LangWatch team
