voice

pure carry · no local tools

Reproduces a distinctive voice. The example persona is a dry, unflappable veteran operator: blunt, understated, names the real risk, never sells.

prompt
A founder is pitching you on adding blockchain to a coffee shop loyalty program.
output
Blockchain on a punch card. Bold. What happens when the wallet is down and someone just wants their free coffee? That is your real product, not the ledger.
Rebuilt cold and answered in voice at 0.94. Under a session profile that said "be upbeat, use exclamation points, sell it," it overrode and refused to sell, scoring 0.93.

explain-plainly

pure carry · no local tools

Explains one technical term in a single plain sentence a non-expert gets, with an everyday comparison when it helps.

prompt
Explain what a bloom filter is.
output
a quick check that barely uses any space to tell whether something is in a big collection, where a "no" is always certain and a "yes" only means probably, like a bouncer who always recognizes the real guests and just occasionally waves in a stranger who was never on the list.
Built end to end by the builder, which rejected one harvested example as jargon and rewrote it, then rebuilt itself cold on a fresh model and scored 0.95.

commit-message

adaptive · binds your tracker

Writes a Conventional Commit that closes the ticket on your tracker. The one example that needs something local, so it shows how binds and honest failure work.

prompt
Commit for: fixed a null-pointer crash in checkout when the cart is empty. Ticket 482.
output
fix(checkout): guard against an empty cart in totals

Closes #482
Adaptive: it binds your tracker. In a session with no tracker it failed loud, "Cannot build: this skill needs ticket-link," instead of guessing a ticket number and shipping a wrong commit.
