What every job needs

- Tools over MCP:
claude mcp addconnects a server and/mcpshows what's connected. See Claude Code MCP. - A command that runs without you:
claude -pruns one task and exits. In CI,--barestarts faster but skips CLAUDE.md, hooks and skills, so pass the rules with--append-system-prompt-file. - A schedule: cloud scheduled tasks with
/schedule, desktop scheduled tasks, or/loopwhile a session is open. See proactive Claude Code.

FAQ
What is Claude Code used for?
Writing and changing code, and the work around it: code and security review, error and issue triage, testing, refactoring, data analysis, SEO and content. Anything it can do through files, commands and connected tools.
Can Claude Code do tasks that aren't coding?
Yes. SEO, content creation and data analysis all work, because they're done through files, a browser and tools such as analytics. See Claude Code for marketing.
How do I run Claude Code on a schedule?
Use cloud scheduled tasks (/schedule), desktop scheduled tasks or /loop, or run claude -p from cron. A Crewmark employee wakes on a heartbeat and takes the next issue from its board.
Do these jobs work with Codex too?
Yes. Every job has a Codex version. The rules are the same, in AGENTS.md instead of CLAUDE.md.
