Built By A Developer.
For Developers.
SIMURAI isn't a company. It's one engineer's answer to a problem every AI-assisted developer eventually runs into: prompts don't scale, and habits don't transfer.
Where the name came from
There's actually a story behind it.
SIMURAI comes from three things that are all true at once, not one clever pun. It's three layers, stacked on purpose.
- 01 — SIMSIM
A personal tribute.
SIMSIM is my father's name. This part isn't a naming exercise — it's how I carry something of his into what I build.
- 02 — AI
The technology.
This whole platform exists to create, organize, share, and master AI Skills. AI isn't a theme here — it's literally part of the name.
- 03 — Samurai
The philosophy.
Discipline. Precision. Craftsmanship. Practice, until it becomes instinct. That's how I want AI skills built — not random prompts, not shortcuts, not just asking AI to handle everything. Learn the skill. Practice the skill. Refine the skill. Master the skill.
My father's legacy, the technology I build with, and the discipline of mastery — that's what gives the name SIMURAI its meaning.
SIMURAI isn't just a name. It's a reminder of where we come from, what we build with, and how we build it.
AI Skills. Mastered.
The code of useful intelligence
Four rules, no exceptions.
- 01
Discipline
A skill isn't done when it works once. It's done when it works the same way every time, under pressure, without babysitting.
- 02
Precision
Vague guidance produces vague output. Every skill here is built from specific, repeatable judgment calls — not generic advice.
- 03
Craftsmanship
Built the way a tool should be built: sharpened through real use, not shipped and forgotten.
- 04
Mastery
Mastery isn't a claim. It's a track record — measured, versioned, and improved on every release.
Bishoy Bishai
Tired of repeating myself.
I'm a software engineer who got tired of re-explaining the same review comments, the same test coverage gaps, and the same architectural tradeoffs to every new AI tool I tried. SIMURAI started as a personal toolkit — skills I built so an AI assistant would work the way I actually work, instead of the way a generic prompt guesses I might work.
