Core Features

∑

Signature-based dedup

Computes output tuple across all probes. Rules with identical signatures are functionally equivalent and removed.

⌗

Built-in 30-word probe set

Covers short/long words, mixed-case, digits, specials, repeated chars. No external wordlist needed.

Extensible probes

Add words via --extra-probes or sample from a wordlist with --probe-file.

Processing Workflow

Step 1

Assemble probe set

Built-in words + extra-probes + sampled from probe-file, deduplicated.

Step 2

Apply rules

Pure-Python interpreter applies each rule to every probe word.

Step 3

Compute signatures

Collect all transformed outputs into a tuple per rule.

Step 4

Deduplicate

Dict maps signature → first rule seen. Duplicates discarded, order preserved.
