pilot-shell vs vessel-browser
pilot-shell: Pilot Shell enhances Claude Code with structured workflows for spec-driven development, efficient bug fixes, and product requirement generation. It integrates quality gates, preserves context, and optimizes token usage, enabling engineers to produce consistent, production-grade code.; vessel-browser: Vessel is an open-source browser runtime for persistent web agents on Linux. It provides a real browser with durable state, MCP control, and a human-visible supervisory UI. It is built for long-running workflows where the agent drives and the human audits, intervenes, and redirects when needed.
