This article explains how to create and configure Claude Code routines—autonomous cloud sessions triggered on a schedule, via API, or by GitHub events. It covers setting up prompts, repositories, environments, and connectors through the web UI, CLI, or desktop app, and illustrates use cases like issue grooming, alert triage, code review, deploy verification, docs drift, and library porting.

• Claude Code routines run autonomously on schedules, API calls, or GitHub events (like pull_request.opened), not just interactively.
• Each run clones repos, executes shell commands or connector calls (Slack, Linear, Google Drive), and pushes changes to claude/-prefixed branches for review as PRs.
• Real use cases include nightly issue grooming with Slack summaries, API-triggered error-threshold triage that opens draft fix PRs, and automated code porting between SDK repos on merge.
• Routines can be built via web UI, CLI (/schedule commands), or the Desktop app's "New remote task" option.
