Tstack

Tstack is a collection of agent skills for coding assistants that automate pull request management and reviews.

Tstack provides a collection of agent skills for coding assistants, cleaned up for general use. These skills work in Claude Code and Codex, falling back to native tools when T3 Code features are unavailable. The toolkit includes skills for full pull request management, such as proving, reviewing, filing, babysitting, and merging changes. Other skills enable multi-model code reviews and automated comment formatting. It is designed for developers who use AI coding agents and want to automate repetitive git and pull request workflows. Requirements include an authenticated GitHub CLI and Python 3.
