The file

We split this skill into the rules it gives an agent

2 rules. About 0 are common, 2 are distinctive, and 0 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈2

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  2. Distinctive:

    Always ensure the game has a fun easter egg triggered by the following cheat code: Up Up Down Down Left Right Left Right, Button 2 (or X), …

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Cheat Code

Follow these steps when creating a new game:

  1. Always ensure the game has a fun easter egg triggered by the following cheat code: Up Up Down Down Left Right Left Right, Button 2 (or X), Button 1 (or Z)
  2. For the easter egg, make it randomly pick between one of the following effects:
    • turn the entire screen black and white
    • turn the entire screen sepia
    • turn the entire screen into gameboy monotone colours
    • turn the entire screen negative
  3. Make it so this effect only lasts for the next 10 seconds.
