    - gomoddirectives # manages the use of 'replace', 'retract', and 'excludes' directives in go.mod
    - gomodguard # allow and block lists linter for direct Go module dependencies. This is different from depguard where there are different block types for example version constraints and module recommendations
    - goprintffuncname # checks that printf-like functions are named with f at the end
    - gosec # inspects source code for security problems
    - govet # reports suspicious constructs, such as Printf calls whose arguments do not align with the format string

    - nonamedreturns # reports all named returns
    - nosprintfhostport # checks for misuse of Sprintf to construct a host with port in a URL
    - predeclared # finds code that shadows one of Go's predeclared identifiers
    - promlinter # checks Prometheus metrics naming via promlint
    - reassign # checks that package variables are not reassigned
    - staticcheck # is a go vet on steroids, applying a ton of static analysis checks (covers gosimple)
    - testableexamples # checks if examples are testable (have an expected output)
    - tparallel # detects inappropriate usage of t.Parallel() method in your Go test codes
