# Generate A2A Agent Card Generate an A2A (Agent-to-Agent) protocol agent card JSON file by analyzing the source code at `$ARGUMENTS`. ## Steps ### 1. Carefully study the source code Do NOT just skim the top-level files. Agents can be complex, multi-file projects. You MUST thoroughly explore the entire folder structure before generating the card. If `$ARGUMENTS` is a local folder path, use Glob to find ALL Python files, YAML/JSON configs, and README files in the folder and its subfolders. Read every relevant file. If `$ARGUMENTS` is a GitHub URL, use `WebFetch` to read the raw file contents. Follow imports to discover additional files. **Where to look** (agents are not always a single file): - **Entrypoints**: `main.py`, `app.py`, `agent_entrypoint.py`, `server.py`, `__main__.py` - **Tool definitions**: tools may be in separate files like `tools/`, `skills/`, `functions/`, or registered via decorators (`@tool`, `@function_tool`, `@mcp_tool`) - **Multi-agent setups**: look for orchestrator/supervisor patterns, multiple agent classes, agent registries, sub-agent folders - **Prompts and system messages**: may be in separate files like `prompts/`, `templates/`, `system_prompt.txt`, or

Step 1: JSON format check

card = json.load(f)
