go-testing covers table-driven tests, subtests, test helpers, and failure message standards. emphasizes diagnosable failures, cmp.Diff for complex comparisons, and semantic error checking over string matching.

go-control-flow covers conditionals, loops, and switch statements in go, with patterns for scoped initialization, range iteration, and type assertions. references external docs for advanced patterns.

go-error-handling covers error wrapping strategy selection (sentinel errors, typed errors, fmt.Errorf) and provides a decision tree for choosing between %w and %v based on caller needs and function position in call stack.

go-context covers function signature conventions for context.Context in go, emphasizing first-parameter placement and avoiding struct storage patterns.

go-packages covers package naming conventions and import organization for go codebases, with emphasis on avoiding generic package names. incomplete guidance on dependency management and package structure.

go-performance provides benchmark scripting and micro-optimization patterns for hot paths in go code, with emphasis on strconv over fmt and profiling discipline.

go-interfaces documents interface design patterns and composition strategies, including consumer-driven interface definition, concrete type returns, and compliance verification via shell scripts.

guides idiomatic go identifier naming across packages, types, functions, and methods using a decision flow and linting script. emphasizes context-sensitive, non-repetitive names aligned with go conventions.
