Install

wiff is written in Rust and builds with a recent stable toolchain. You do not need to clone the repository to install it.

From git

Install straight from the repository:

cargo install --git https://github.com/wez/wiff.git wiff

This builds the wiff binary and places it on your PATH (usually ~/.cargo/bin).

From a checkout

If you have cloned the repository, install from the workspace instead:

cargo install --path crates/wiff

Verify

Confirm that the binary is runnable:

wiff --help

Reviewing with an agent

wiff ships an agent skill that teaches an agent to read and annotate a review through the wiff command line, while the TUI stays yours. Expand the bundled skill into your data directory and print the path to its SKILL.md with:

wiff skill-path

Point your agent at that file, or copy the skills/wiff-review/ directory into wherever your agent looks for skills. The expansion rewrites each wiff call to the absolute path of your binary. Once installed, ask your agent to review the diff or address the existing comments; it discovers the active session for the checkout on its own.

Some agent harnesses can load the skill on demand, without setting up its path in advance. If yours does, a prompt like this is enough to bootstrap it:

Load the wiff skill; run wiff skill-path to find it.
