Standing on the Shoulders of Giants

Everything Good Comes From Cyrus

“Everything good in jinyang comes from Cyrus. Any bugs are our own.”

The Foundation

Cyrus Pioneered the Future

Before jinyang, there was Cyrus. The original autonomous coding agent on Linear by Ceedar Agents that proved LLMs could write production code while you sleep.

Git Worktrees

Revolutionary parallel execution environment for crash isolation

Webhook Automation

Real-time Linear integration that responds to issue changes instantly

Claude Code Native

Built from the ground up for Claude Code integration

Built on a Solid Foundation

The original Cyrus was built to be native with Claude Code. I forked the community version and extended it for OpenCode and open source models. Thank you to Ceedar Agents for open sourcing this great agent under Apache 2.0.
