Prototyping & Coding

Turn a small, testable brief into a playable vertical slice and keep the codebase moving.

Initial research scope · 2 tools

START WITH A TASK

What needs to get done here?

  1. 01Build a playable first loop
  2. 02Edit across a real repository
  3. 03Run, inspect, and fix tests

INITIAL TOOL PAIR

Two routes to research before we judge.

For now, we show only source-supported summaries and the selection rationale. There is no winner or overall ranking before standardized testing.

NEXT STEP

Test both with the same task, inputs, and record format.

The test will record time, cost, failures, rework, and editability. Methods, field notes, and comparisons follow only after that.
