    ## enabled by default
    - errcheck # checking for unchecked errors, these unchecked errors can be critical bugs in some cases
    - gosimple # specializes in simplifying a code
    - govet # reports suspicious constructs, such as Printf calls whose arguments do not align with the format string
    - ineffassign # detects when assignments to existing variables are not used
    - staticcheck # is a go vet on steroids, applying a ton of static analysis checks
    - typecheck # like the front-end of a Go compiler, parses and type-checks Go code
    - unused # checks for unused constants, variables, functions and types
    ## disabled by default
    - asasalint # checks for pass []any as any in variadic func(...any)
    - asciicheck # checks that your code does not contain non-ASCII identifiers
    - bidichk # checks for dangerous unicode character sequences

    - copyloopvar # detects places where loop variables are copied (Go 1.22+)
    - cyclop # checks function and package cyclomatic complexity
    - dupl # tool for code clone detection
    - durationcheck # checks for two durations multiplied together
    - errname # checks that sentinel errors are prefixed with the Err and error types are suffixed with the Error

    - goimports # in addition to fixing imports, goimports also formats your code in the same style as gofmt
    - 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
    - lll # reports long lines

    - nestif # reports deeply nested if statements
    - nilerr # finds the code that returns nil even if it checks that the error is not nil

    - noctx # finds sending http request without context.Context
    - nolintlint # reports ill-formed or insufficient nolint directives
    - nosprintfhostport # checks for misuse of Sprintf to construct a host with port in a URL

    - sloglint # ensure consistent code style when using log/slog
    - spancheck # checks for mistakes with OpenTelemetry/Census spans
    - sqlclosecheck # checks that sql.Rows and sql.Stmt are closed
    - stylecheck # is a replacement for golint
    - tenv # detects using os.Setenv instead of t.Setenv since Go1.17
    - testableexamples # checks if examples are testable (have an expected output)
    - testifylint # checks usage of github.com/stretchr/testify
