Tools

Cross-platform shell built around structured data: pipelines pass tables instead of plain text, and you can open and query JSON, CSV, TOML and more directly. Default builds include nu --mcp, which serves it to agents as an MCP server.

Static analysis for shell scripts: flags syntax errors and common bash/sh pitfalls such as quoting and variable expansion, with suggested fixes. Good for checking agent-generated scripts and easy to add to CI.

Loads and unloads environment variables per directory: reads .envrc (and optionally .env) when you enter a project and restores the environment when you leave, so configs and secrets do not leak between projects. Hook it into bash, zsh, fish or another shell first.
