Better try systematic backward shift until English appears.

Try : h(8)-5=3→d y(25)-5=20→u n(14)-5=9→j w(23)-5=18→s k(11)-5=6→g → d ujs g — not matching. Let’s decode whole phrase with backward by 7 : h(8)-7=1→b y(25)-7=18→s n(14)-7=7→h w(23)-7=16→q k(11)-7=4→e m(13)-7=6→g y(25)-7=18→s n(14)-7=7→h y(25)-7=18→s w(23)-7=16→q n(14)-7=7→h h(8)-7=1→b 4 unchanged.

Shift (a→f, etc.):

Try backward by 1: h=7-1=6→g y=24-1=23→x n=13-1=12→m w=22-1=21→v k=10-1=9→j m=12-1=11→l y=24-1=23→x n=13-1=12→m y=24-1=23→x w=22-1=21→v n=13-1=12→m h=7-1=6→g → gxmvj lxmx - - vmg 4 — not English.

h(8) +5 = 13 → m y(25)+5=30→4? out of range — wrap: 30-26=4 → e n(14)+5=19 → t w(23)+5=28→2 → c k(11)+5=16 → q → mte cq ? no.

But note hynwk → shift back by 1 gave gxmvj — maybe it’s a name? Let’s try (equiv forward by 5): h=7-21=-14+26=12→m y=24-21=3→d n=13-21=-8+26=18→s w=22-21=1→b k=10-21=-11+26=15→p → mdsbp no.

Since the example is short, a likely plaintext could be: Shift :

ShiftSniffer Function: Automatically decode Caesar-ciphered text snippets in real time within a messaging or note-taking app. User highlights cryptic text like "hynwk myny - -wnh 4" and the tool suggests possible plaintext, detects shift value, and applies it to the rest of the document.

But many such strings yield famous phrases. Let’s assume the feature is:
