Although the documentation does mention help/doc and help/dir, it's not obvious for users how to get help on tools unless they read the entire doc page carefully.
It would help users figure out how to use tools if the -Ttools functions were a bit more verbose and suggested how to get help.
I don't think much can be done about this:
$ clojure -Ttools
No function found on command line or in :exec-fn
but adding a help function would mean that the next thing a user might try could work:
$ clojure -Ttools help
Namespace clojure.tools.tools.api loaded but function not found: help
Telling users that the following can be used to get a list of available functions or to get more expansive help would guide them to the next function to use:
$ clojure -A:deps -Ttools help/dir
install
list
remove
show
$ clojure -A:deps -Ttools help/doc
...
In addition, the list function could suggest how to get help on a specific, installed tool:
$ clojure -Ttools list
TOOL LIB TYPE VERSION
clj-new com.github.seancorfield/clj-new :git v1.2.362
new io.github.seancorfield/deps-new :git v0.4.0
nvd io.github.rm-hull/nvd-clojure :git 4b0c448
poly io.github.polyfy/polylith :git 768642a
tools io.github.clojure/tools.tools :git v0.2.1
# add the following (arbitrarily picking the first one, perhaps):
For help with a specific tool, e.g., clj-new:
clojure -A:deps -Tclj-new help/doc
The same could be added to the show function.
