GSoC 2026 Interest — #5 Performance Monitoring Dashboard

[SHIHAB69]

Hi everyone! I'm Sihab, a Software Engineer interested in contributing to Gemini CLI for GSoC 2026 — specifically the Performance Monitoring and Optimization Dashboard idea.

I've already set up the dev environment, ran the full test suite, and done a deep read of the codebase — particularly the telemetry infrastructure in packages/core/src/telemetry/. I noticed that many metrics like recordStartupPerformance(), MemoryMonitor, and tool execution breakdown are already defined but have no in-terminal UI surface yet.

A few questions for the mentor (@sehoon38 or whoever is available):

1. Is the /perf or /stats command the preferred entry point for the dashboard?
2. Is there a preferred in-memory aggregation strategy, or should it hook directly into the existing OTEL pipeline?
3. Are there any constraints on adding new React/Ink components to packages/cli?

Thanks!
