Which programming languages are supported for source mapping?

While it is highly optimized for Go applications using Pyroscope, any language that generates pprof-compatible profiles with source file information can be analyzed.

What tools are required for this skill to work?

You need the profilecli binary and pprof (or go tool pprof) installed in your PATH to query and analyze profiling data.

Does this skill work with Grafana Cloud?

Yes, it supports Grafana Cloud by using a service account token and the appropriate data source proxy URL.

How does it handle different versions of the source code?

The skill attempts to verify the git ref from the profiling data against your current HEAD to warn you if line numbers might have shifted since the profile was captured.

Analytics & Monitoring

Analyzes Pyroscope profiling data using profilecli to identify and optimize performance bottlenecks in your source code.

The Pyroscope Performance Insights skill empowers developers to perform deep performance analysis directly within Claude Code. By leveraging the profilecli tool and pprof, it queries remote Pyroscope or Grafana Cloud servers to retrieve CPU, memory, and contention profiles. The skill goes beyond raw data by automatically correlating profiling results with your local repository's source code, identifying 'hot' functions, and providing a structured report with actionable optimization suggestions to improve application efficiency.
