[GSoC 2026] Proposal Discussion: Idea 5 - Performance Monitoring and Optimization Dashboard

[codewithyuvraj24]

Hi @sehoonshon and the Gemini CLI team!

I'm Yuvraj, and I am very interested in participating in GSoC 2026 for the Gemini CLI. I would love to build out Idea 5: Performance Monitoring and Optimization Dashboard.

I have been exploring the codebase and recently submitted PR #22267 fixing the Browser Agent settings bug, so I am getting comfortable with the architecture.

Why this idea excites me:

As the agent grows in complexity (more tools, MCP servers, etc.), visibility into execution times, token usage, and memory bottlenecks will be critical for both end-users and core contributors. Building a rich, interactive React/Ink dashboard to visualize this data is exactly the kind of frontend-meets-CLI challenge I’m looking for.

Initial Thoughts & Approach:

1. Data Collection Layer: I plan to hook into the existing telemetry/logging infrastructure (like ClearcutLogger and the OpenTelemetry implementation) to aggregate session data seamlessly without impacting runtime performance.
2. Dashboard UI (React/Ink): Build a dedicated /stats (or similar) command that intercepts the standard chat loop to render a full-screen or persistent inline Ink component.
3. Key Metrics:
   • Startup latency breakdown (Node instantiation vs. Auth vs. Config load)
   • Tool execution times (identifying slow external tools)
   • API latency & token usage stats

Questions for the maintainers:

Before I finalize my formal proposal, I wanted to get your thoughts on a few architectural decisions:

1. Currently, telemetry events are batched and sent to Clearcut/OpenTelemetry. Would you prefer the local dashboard to maintain its own FixedDeque of recent session events in memory, or should we query a local SQLite/JSON persistence layer if the user wants historical stats?
2. Are there specific performance bottlenecks right now (e.g., startup blocking) that you want this dashboard to explicitly highlight out-of-the-gate?

Looking forward to your feedback so I can refine my proposal!

Best,
Yuvraj
