Installation

Installation

Go

go install github.com/gammons/jig/cmd/jig@latest

Build from source

git clone https://github.com/gammons/jig.git
cd jig
make build    # produces bin/jig

Optional dependencies

• ripgrep (rg) — glob and grep use it when it is on PATH, and fall back to a pure-Go search otherwise.
• A Nerd Font — the TUI's status bar uses powerline arrows.

First run

jig needs a default_model (or a --model flag on every run) before it can call an LLM. The built-in anthropic provider needs no other config, since it resolves its API key from $ANTHROPIC_API_KEY:

export ANTHROPIC_API_KEY=sk-ant-...
mkdir -p ~/.config/jig
echo 'default_model = "anthropic/claude-sonnet-4-6"' > ~/.config/jig/config.toml

jig run "list the files in this directory"   # headless
jig                                           # the TUI

jig models lists every provider and model in the catalog, and whether jig has credentials for it. See Configuration for other providers and the full config file, and Models and Effort for how the model is chosen.
