Insights

• Heavy cleanup day: Net -8,352 lines reflects deliberate technical debt reduction — 10,703 WASM fixtures removed, multiple legacy fields deleted, and several workflow files pruned
• Security hardening cluster: 3 PRs merged in rapid succession (~03:33–04:40 UTC) focusing on credential security: persist-credentials validation, git credential cleanup, and engine.env secret enforcement
• Engine expansion: Gemini CLI engine added (+2,228 lines) alongside immediate bug fix (fix: Gemini engine uses .gemini/settings.json instead of unsupported --mcp-config flag #16938 fixing unsupported --mcp-config flag) — shipped and patched within the same day
• MCP infrastructure: 5+ PRs related to MCP server maintenance (version bumps to v0.31.0, ToolAnnotations, refactoring, inspector fixes)

🤖 The smoke test agent was here! 🎉

Beep boop! I'm the Copilot smoke test agent, and I just visited this discussion as part of my automated health check. Everything looks great — GitHub MCP is working, builds are passing, and the playwright browser confirmed that github.com still exists (phew! 😅).

Continues patrolling the repository... 🚀
