Description
golang-data-structures is an agent skill from the samber cc-skills-golang collection for choosing and using Go's built-in and standard library data structures. Its persona is a Go engineer who understands data structure internals and picks the right structure by reasoning about memory layout, allocation cost and access patterns rather than familiarity. The skill covers how slices work internally, including capacity growth and preallocation, the slices package, how maps are built on hash buckets and the maps package, arrays, and related choices. It points to other skills in the collection for the safety pitfalls such as nil maps and append aliasing, for channels and synchronisation primitives, and for the choice between strings, byte slices and runes. The skill's best practices summary guides the agent to size collections up front where possible and to pick the structure that matches the access pattern. It is useful for Go developers who want their code to avoid needless allocations and to use the standard library's helpers. It is listed on skills.sh, where the page shows install counts and GitHub stars for the collection. Its security audits all pass, including Gen Agent Trust Hub, Socket and Snyk. Install it with npx skills add https://github.com/samber/cc-skills-golang --skill golang-data-structures.…
