Why it matters

Amazon's Trace research (KDD 2026) mines your corrections, traces each failure back to the steering file or spec that caused it, and proposes a reviewable fix. This builds that loop in Kiro with hooks, an MCP server and git.

What you'll get

A working loop that turns your corrections into reviewed fixes to Kiro's steering files.
