Claude Code ships automated PR review system

Claude Code represents a major shift toward high-autonomy agentic coding, favoring a terminal-native workflow over traditional IDE extensions. The /init command creates a CLAUDE.md context file, effectively giving the agent a "project constitution" for architectural and styling rules, while native MCP support allows it to pull context from Jira, Slack, or live databases. Unlike Cursor's interactive "ambient" assistance, Claude Code is optimized for "heavy lifting" tasks like complex refactors and automated PR generation via /submit. The consumption-based pricing model can scale costs rapidly for power users, making it a high-performance tool for senior devs. Security features like config.json and execution guards address the inherent risks of giving an LLM terminal access.
