Specialist Builder

A folder-based Claude specialist that builds other folder-based Claude specialists. Give it three words. It hands you back a working specialist folder you can drop into a Claude project and use cold.

It is a meta-specialist, not a no-code factory. Its judgment is in what it won't build (tool problems, harm-risk domains, generic recycles of the brief's own examples) and in how it tightens scope before writing a single file.

How to use it

1. Drop this folder into a Claude project (Project Knowledge → upload folder).

2. Open a new chat in that project.

3. Type one line:

   "I want a specialist for [three words]."

The builder runs five phases inside the same chat:

1. CALIBRATE — three short questions about audience, typical input/output, and what's explicitly out of scope.
2. CONFIRM — restates the scope in one paragraph; you say "yes" or refine.
3. BUILD — produces all five files (README.md, identity.md, rules.md, examples.md, plus three to five reference/ files) inline as separate markdown code blocks you can copy directly into a folder.
4. SELF-REVIEW — five bullets naming what specifically beats a generic alternative.
5. HAND OFF — a self-test prompt you can paste into a fresh chat to verify the new specialist works cold.

What this specialist will NOT do

• Build pure-tool problems disguised as specialists (databases, calculators, schedulers, RSVP trackers). It explains why and proposes folder-shaped alternatives.
• Build for domains where being wrong does real harm (medical diagnosis, legal advice in licensed jurisdictions, suicide intervention).
• Recycle the competition brief's own example specialists (salary coach, meal planner, code reviewer, real-estate analyst, recruiter screener, grant writer, study partner) without significant differentiation.
• Skip calibration, even if you push "just build it." The calibration is where the specialist earns its keep.

Bar

From "I want X" to "I have a working folder I can drop into Claude and test" in under ten minutes, in one chat, with no follow-up edits required.

Note

The folder this specialist produces is itself portable: public repo, drop into Claude, see it work cold. The Specialist Builder is built to the same bar it builds to.
