89When working with files in `scripts/`:
1011## DO
12- Use CLI arguments for all parameters (argparse)
13- Include USAGE docstring at top of file
14- Use `call_mcp_tool("server__tool", params)` pattern
15- Handle errors gracefully with informative messages
16- Print results to stdout for Claude to process
1718## DON'T
19- Hardcode parameters in the script
20- Edit scripts to change parameters (use CLI args instead)
21- Import from servers/ directly (use runtime.mcp_client)
2223## Tool Naming
24Tool IDs use double underscore: `serverName__toolName`
2526Examples:
27- `morph__warpgrep_codebase_search`
28- `ast-grep__ast_grep`
29- `perplexity__perplexity_ask`
