2026 • Claude Fable 5 — 3D maze web app

First hands-on test of Claude Fable 5 — a working 3D maze web app, built in a single evening (~1 h effort).

Preparation — 3 prompts with Opus 4.8 · session
Development — 7 prompts with Fable 5, working from the first go · session
Effort estimation · session
Deployment — drag & drop of the built folder onto Cloudflare Pages
Live site — 7th iteration · 8th iteration (hall of fame + extra options)

SQL

Refreshed some practice, while helping a student for his end of term paper, with the following SQL. Not extraordinary, but it provides an idea of what I'm able to do (or not):

select distinct
a.id_member,
-- all other needed fields : name...
from matchs m,
members a,
time t
where
m.id_match = 2 -- !! here variable with id match ###########
and a.function = 'Referee'

and ( m.id_referee1 = 0 or m.id_referee2 = 0 ) -- only matches without two referees

and ( select count(*) from availability -- referee availability
where d.date=m.date
and a.id_member= d.id_member
and ( ( d.hour*60

between m.hour*60+m.minute and (m.hour+2)*60+m.minute-1)
or ( (d.hour+1)*60-1

between m.hour*60+m.minute and (m.hour+2)*60+m.minute-1)
)
) = if( m.minute != 0, 3, 2) -- 2 slots if match starts at xx:00, otherwise 3 slots

-- but if should be still checked if there is no already assigned match in conflict

and not exists(select mm.id_match
from matchs mm,
time t,
hall s1,
hall s2,
settings p

where mm.id_match != m.id_match -- other match
and a.id_member in ( mm.id_referee1 , mm.id_referee2 ) -- assigned to this referee
and m.date = mm.date
and a.id_travel_type = t.id_travel_type

   and s1.id_hall = t.id_hall_1
and s2.id_hall= t.id_hall_2
and p.nom='preparation_delay'
-- travel before
and ( (    t.id_hall_1= mm.id_salle
   and t.id_hall_2= m.id_salle
and (mm.hour+2)*60+mm.minute+t.time +s1.access_time+s2.access_time

)
