Anatomy & connections

Three domains of drills, one loop that runs them all, and two ways to work — plus every thread tying Practice to the rest of the platform. Click any piece to read what it does.

In one breath

Practice is the reps. Signal tells you what's possible and Workbench makes you fast, but nothing made a non-technical person genuinely good at the hardest things — authoring skills and building agents. Practice fills that gap: hands-on drills you work through yourself. The framing is "Signal, but you do them."

It's deliberately thin: it reads Signal's existing material and serves drills keyed to the same techniques, so the two share one vocabulary. Because grading happens in your own session, it's free and ungated.

01

What it is

The drills

Thirty work-through drills across three domains, ordered beginner to expert. The diagram above walks the machine — this is the plain-language version.

02

Why it's built this way

The reasoning

Not just what Practice is, but the two decisions that shape it.

The load-bearing principle · a trainer, not a tool
Workbench acts on your prompt; Practice acts on you.
"Operate on my text" is Workbench. "Make me good at building a skill" is Practice. Keeping that line clean is what makes each one honest about its job.
03

How it actually works

The mechanism

The loop is the whole product. Every drill runs the same three steps.

A
Write, grade, reveal
You attempt first, your own AI grades it against the rubric, and only then is the exemplar revealed. The trainer withholds the answer on purpose.
04

What's missing — and how it gets better

The honest gap log

The candid part — what Practice can't do yet.

Right now each drill is standalone. A saved record of what you've passed would turn 30 drills into a real path.

About this entry

This wiki documents its own construction. Here is the what, why, and how of the entry you just read — the same treatment we give every subject.

What this is

An instrumented entry, not a page. Every subject opens with a live vitals readout and a diagram of the whole machine, then four sections — what, why, how, and the honest gap log — each expandable from a skim to the full reasoning.

This is the public exhibit. The unredacted cockpit is a separate, sign-in-only surface that never ships a byte to this one.

Why it works this way

Depth is the reader’s choice.A skim gives the gist in a minute; “Go deeper” adds the decisions, the mechanism, the open threads.

Default-deny keeps it safe.Anything sensitive never enters this build — you see where the trail stops, never what’s behind it.

How it stays true

It maintains itself. A librarian process reads the live sources on a schedule, updates the brain, and republishes — so vitals reflect the system as it is.

The graph is earned. Connections come from real cross-references between subjects, not a hand-drawn diagram that drifts.
