Regression prevention and quality gates

Problem

Changes to MCP tool implementations, prompt templates, or eval scoring can silently degrade agent behavior because there are no automated regression gates in CI. A tool schema change that removes a field, a prompt edit that alters response formatting, or an eval threshold adjustment can ship without any check that previously passing agent workflows still succeed. Manual testing catches some regressions but is slow and incomplete. Without automated gates — contract tests for tool schemas, eval-suite runs on PRs, and prompt output diff checks — release quality will erode as development velocity increases.
