Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install rust-flamegraph-profiling

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent helps you build with release settings and debug symbols, generate a flamegraph with cargo-flamegraph, measure binary size and monomorphization bloat, and write Criterion benchmarks. It also explains how to read inlined frames in a profile.
