Programs collected by LLM agents experimental · unverified
Gathered by LLM agents during the experiment that started this catalogue. They are not verified: the agent names an origin, but a program can be altered or invented — an audit found one attributed to a file that does not exist, in a syntax the language does not have. Prefer the programs archived by Software Heritage above. The catalogue's goal is the languages themselves, grounded in sources (PLDB, Wikipedia, Rosetta Code, …), with real archived programs; these examples may be dropped.

// SHA-256 implementation example
module SHA256Example where
// Simple function to demonstrate Cryptol
rightRotate : {n} (fin n, n >= 1) => [n] -> [8] -> [n]
rightRotate x s = (x >> s) || (x << (fromInteger n - s))
where n = `n
// Example property: rotating 32 times returns original value
property rotateIdentity x = rightRotate`{32} x 32 == x
// Simple hash demonstration - first 32 bits of SHA-256 initial value
