Package: hal 0.1.4

Mark Dippold

hal: Agentic Coding Assistants

A native R interface to agentic coding assistants. Talks directly to local command line interfaces ('GitHub Copilot', 'Anthropic' 'Claude Code') over standard input/output and to a local 'vscode.lm' bridge inside 'Positron', providing multi-model chat, tool calling, and in-session R evaluation. Supports a single stateful hal() session as well as disposable hal_ask() / hal_do() pipeline verbs, plot capture so models can see graphics, verified data transforms, and user-defined tools.
