Urda Anvil

An anvil: the tools, settings, rules, and software that blend into one workbench for building better software with LLMs.

Start Here

The anvil is a working setup for building software with LLMs, from the agent CLIs to the rules they follow. This site documents it: which models run where, what each tool is allowed to do, and the rules the agents follow. New here? Start with Balancing the Anvil to pick a model and a harness. The AI Glossary can help explain new terms along the way. Then read MCP and Rules for the setup behind them. If you land on Claude Code, install the Forged Status Line. It takes a minute and shows your usage.
