Requirements:

  • Rust — the toolchain is pinned by rust-toolchain.toml; rustup installs it automatically on first build.

  • DotSlash — required so hermetic tools under bin/ (notably bin/protoc) can download and run. Install it and ensure dotslash is on your PATH before building:

    cargo install dotslash
# or: prebuilt packages — https://dotslash-cli.com/docs/installation/

/usr/bin/env dotslash --help   # sanity check

  • protoc — proto codegen resolves bin/protoc via DotSlash, or falls back to a protoc on PATH / $PROTOC.

  • macOS and Linux are supported build hosts; Windows builds are best-effort and not currently tested from this tree.

cargo run -p xai-grok-pager-bin              # build + launch the TUI

cargo build -p xai-grok-pager-bin --release  # release binary: target/release/xai-grok-pager

cargo check -p xai-grok-pager-bin            # fast validation

The binary artifact is named xai-grok-pager; official installs ship it as grok. On first launch it opens your browser to authenticate — see the
