I ended up finding one place to start... kdenlive uses XML files to
describe effects, and it refers to a bunch of frei0r plug-ins. So I
wrote a dumb little program to scan
'/usr/share/kdenlive/effects/frei0r*.xml' and print out names,
descriptions and parameters, e.g.

Cartoon (frei0r.cartoon): Cartoonify video, do a form of edge detect
- triplevel (constant) = 500 (0 - 100000)
- diffspace (constant) = 1 (0 - 256)

I'll attach the file to use or discard as you like. Maybe it's useful
to some other people.
