Do I need a specific tmux layout?

The skill defaults to expecting the test runner in pane 0.1, but it includes instructions for listing and targeting any specific pane in your session.

How does it help with the TDD cycle?

It automates the Red phase by detecting failures, the Green phase by verifying your code changes, and the Refactor phase by ensuring tests remain passing.

Can it start the test runner for me?

Yes, using the tmux send-keys command, the skill can trigger specific test commands or restart watch processes in designated panes.

Does this skill work with any test runner?

Yes, it is language-agnostic and works with cargo, pytest, jest, vitest, go test, and more by capturing raw terminal output.

Security & Testing

Orchestrates Test-Driven Development workflows by reading and managing test output directly from tmux panes across multiple programming languages.

About

The tmux-tdd skill enables Claude to interact seamlessly with terminal multiplexer environments, allowing it to monitor test runners in real-time without interrupting the main coding session. By capturing output from adjacent tmux panes, Claude can parse test results for Rust, Python, JavaScript, and Go, identify specific failure patterns, and iterate through the Red-Green-Refactor cycle autonomously. This skill is essential for developers who utilize split-pane terminal setups and want an AI assistant that can observe live test feedback, suggest code fixes, and verify results without manual context switching.
