issue with pflag flagset
My understanding is that you can use pflag as a drop in replacement of the standard lib's flag (import flag "github.com/spf13/pflag"). So it can be used as a standalone lib I suppose.

Which packages do you recommend for building cli tools?
I realy enjoyed the patched version from spf13 with "--" support https://github.com/spf13/pflag

Define custom command-line flag types in Go 1.19
Nice, but Cobra (with pflag underneath) is so, so better.

-h --help -help help --? -? ????
Not by default on stdlib. There are libraries available though - https://github.com/spf13/pflag

Coral, a friendly Cobra fork with nearly all its features, but only 4 dependencies
Flag functionality is provided by the pflag library, a fork of the flag standard library which maintains the same interface while adding POSIX compliance.

What are your favorite packages to use?
oklog/ulid to generate IDs. coreos/go-oidc for validating JWTs I get from auth. google/go-cmp for comparing structs in tests (unless the project is already using Testify). spf13/pflag because life's too short for Go's flag handling. getkin/kin-openapi for validating reqests/responses against my OpenAPI spec (in tests).

akamensky/argparse: Argparse for Golang. Just because "flag" sucks!
What are the benefits of this package over the widely used spf13/pflag?
-
Go’s highly modular nature makes it particularly good for situations where requirements are changing or evolving.
