I actually haven't found a site that lists the information, instead I had to test it in game.

Many of the skills are a bit more straight forward than they seem. For the Attack/Defense/Health/Status/Element boosting skills they can be checked on the status screen and for Status/Element, calculated to find the % of increase(like Bombay Boost increase Blast by 20%, which stacks wit Felyne Pyro up to 25%), though some also just tell you how much the increase is(like the Health Up S/L). Universal can be checked similarly, but during a battle with a large monster once it becomes angry.

For some skills though, it'll take testing, for others it'll take more testing as well as other information regarding the cats. Bombay Boost and Morph Ball Bomb fall into the prior. Stamina Drain & Knockout King fall into the latter, as one would need to know the Exhaust and Stun Values of the cats attacks, then calculate to find the increase from those 2 skills. And while Landmaster only lists the extended duration, their might be a hidden buff to the damage, after all, some description aren't accurate which brings me to the next one.

Baddest Cat Ever says it increases Health and Attack when health is 40% or less, but the only way that would work is if it increased Max health as, if you actually healed some health it could counter the rest of the skill. And in testing, sure enough, there are no changes to the health at all and the attack buff is 10% of your melee/range. The attack buff also seems to round up if the decimal is 6 or more, which is odd given how everything else in the game rounds down.

Omniresist is likely just +5 to all elements. And Counter Boost and Support Priority might be difficult to calculate, but they'd both increase the amount of gauge obtained from being hit or from everything, by a certain %.
