Includes 27 harness subsystems—hint engine with 30+ rules, outcome classification, pattern learning, and DOM compression achieving 15x token efficiency—that guide AI agents and prevent costly error cascades. Achieves ~300MB memory for 20 parallel sessions versus 5GB+ for traditional approaches, while remaining invisible to bot detection and enabling authenticated cross-site operations.
About opencode-browser
michaljach/opencode-browser
Browser automation plugin for OpenCode AI editor - Control Chrome/Edge with AI, automate web testing, scraping & form filling via MCP integration
Implements performance-optimized prompting that biases the AI toward faster browser workflows (preferring direct navigation, minimizing expensive snapshots/screenshots) while eliminating artificial reconnection delays for immediate retries. Built on the Model Context Protocol (MCP) standard, it loads as an OpenCode plugin via npm and communicates with the Browser MCP server through stdio transport, automatically detecting browser-related tasks and preserving browser state across session compactions.
