v0.1.5

skillrank v0.1.5

Verifies the binary it downloads before swapping it in: every release publishes
a .sha256 next to the asset, and nothing is written over the running executable
until the downloaded bytes hash to exactly that digest. Failing to fetch the
checksum is a refusal too, matching what install.sh has always done.

Tells you when a new version exists instead of waiting to be asked, once a day,
on one line, and never at the cost of the command you actually ran.

Lets the agent notice it needs a skill rather than only responding when you ask
for one, and reports the effort a skill saves — turns, wall clock and cost —
not just pass rate and tokens.
