Security audit for Go applications including net/http servers, Gin/Echo/Chi/Fiber frameworks, database/sql injection patterns, template auto-escape, context propagation, goroutine race conditions, file path handling with filepath.Join, and Go-specific patterns. Use this skill whenever the user mentions Go, golang, net/http, Gin, gin-gonic, Echo, labstack/echo, Chi, go-chi, Fiber, gofiber, database/sql, sqlx, GORM, html/template, or asks "audit my Go app", "Go security review", "gosec". Trigger when the codebase contains `go.mod`, `*.go` files, or Go in the deployment.
