Building human-first and machine-friendly CLI applications
summary
Builds a CLI catalogue of PyCon talks using clig.dev guidelines and scaffolds the project with Cookiecutter plus poetry, implements commands with typer and Rich. Project uses SQLite with a configurable dev DB env var, generates about 20 starter tests, supports interactive prompts vs noninteractive CI use, offers shell completion (occasionally flaky), prints rich tables plus plain and JSON, keeps headers on stderr so pipelines can wc -l, enforces zero/nonzero exit codes, and adds YouTube links; most features work with minor install hiccups.
