Contributions are very welcome. Feel free to submit pull requests for new features and bug fixes. For new features, please raise an issue first so we can discuss the approach - this will go a long way to ensuring your pull request is accepted.
The rules every change has to meet are in AGENTS.md; the practical guide (setup, branches, how review goes) is in CONTRIBUTING.md. Security issues go through SECURITY.md, never a public issue.
You can use AI tools to write code, tests or docs for TMS. What is expected of the person who opens the pull request is in AGENTS.md, under "Working with AI tools". That file is written for coding agents as well as for people, so that a tool pointed at the repository reads the same rules you do.
