Cohort Scripts

Scripts for managing the NHCarrigan spring cohort programme. Covers the full lifecycle: applicant evaluation, Discord server setup, team assignment, member onboarding, activity tracking, and member removal.

Most scripts interact with the Discord API and require a DISCORD_BOT_TOKEN. Several also use the gh CLI for GitHub operations.

Getting Started

Run scripts via the interactive runner from the project root:

make run
# Select: Python → cohort → <script>

Or run directly:

cd python && op run --env-file=../prod.env -- uv run python cohort/<script>.py

Prerequisites:

• Run make install-py to set up the Python virtual environment.
• Most scripts require DISCORD_BOT_TOKEN set in prod.env.
• Scripts that manage GitHub teams require gh auth login to be run first.
