The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill references technical blog posts and documentation from databend.com, fast.github.io, and a public GitHub repository from an established developer (github.com/skyzh). These sources are used for educational reference and do not involve the download or execution of untrusted scripts.
[COMMAND_EXECUTION]: The documentation includes standard Rust development commands for profiling and optimization, such as cargo build --timings, llvm-profdata, and rustflags configuration. It includes a specific command to clear a temporary build directory (/tmp/pgo-data) as part of a Profile-Guided Optimization (PGO) workflow, which is a legitimate and localized operation.
[SAFE]: The skill content is focused purely on Rust language patterns (error design, type exercises) and compilation tuning. No signs of prompt injection, obfuscation, persistence, or data exfiltration were found.
