If I were running D&D 3rd edition, there would be nothing at all keeping me from allowing characters to "automatically" find secret doors and treasure troves in the event that their players described specifically how and where they search for them. Likewise, running OD&D, nothing is stopping me from handling the entire searching process with one fell Wisdom check for everybody. Neither of these things is old school or new school. They are features of the DM's play style and decision making process.
This is a comment that frequently comes up in regards to the Old School Primer.
At its surface, this is true: there is nothing whatsoever stopping a 3E DM from allowing players to find traps, secret doors, etc. To whit, there's nothing stopping a DM from allowing players to successfully do stuff based on the verbal description of their actions, rather than a skill check.
The problem is this: In skill-based games like 3E (and 3E is by no means the only RPG to be skill-based), it is all too easy to assume that, because there is a Skill called Diplomacy, for instance, this is what should be used determine whether or not a character successfully negotiates his way out of a jam. Simply having a skill called Gather Information, implies that information is gathered by a skill check, not by coming up with a clever plan and implementing it. Both of these situations happened to me in a 3.5 session not 6 months ago, run by a good DM. Nonetheless, he was going by skill checks, not player interaction.
It would, perhaps, be different if the 3.5 skill descriptions included a line such as, "with a successful check, the player discovers the desired information. Alternatively, if the player comes up with a brilliant plan to discover such information, no skill check is necessary.", but they do not.
Matt's Primer is specifically aimed at reminding players and DMs that there is another way of resolving "skill-like" actions. If you run a newer edition game and get that, kudos! You're an excellent DM. But, many excellent newer edition DMs don't run things that way, too. And many players and DMs of newer edition games who are *used* to running things with a skill check will find the Primer to be a useful guide on how to run things without skill checks.
