The Agent Skills Directory

[COMMAND_EXECUTION]: The skill defines numerous commands for building, profiling, and benchmarking Rust applications using tools such as cargo, samply, perf, simpleperf, adb, and xctrace across various platforms (Host, Android, iOS). These operations are routine for performance optimization tasks.
[EXTERNAL_DOWNLOADS]: Instructions guide the installation of several Rust-related performance utilities from the crates.io registry using cargo install --locked. Tools mentioned include samply, flamegraph, sccache, cargo-llvm-lines, and rustfilt. It also covers the installation of system packages like perf via standard Linux package managers.
[PRIVILEGE_ESCALATION]: The skill provides a specific command to modify kernel.perf_event_paranoid using sudo tee on Linux systems. This enables unprivileged users to collect performance data via the perf subsystem, which is a standard configuration requirement for the described profiling workflows.
