Context Workshop — AI Native DevCon London 2026

Don't Write Prompts, Write Software — Baruch Sadogursky & Macey Baker.

A live, build-it-with-the-room session on treating context as software: take a working but bloated "uber-prompt", decompose it by determinism into skills (conditional behaviour), scripts (the deterministic parts, with real tests), and rules (the mandatory checks), then package the whole thing as a distributable plugin — and apply the same discipline to the context artifacts themselves, with evals as their tests.

The artifacts get built live during the session; this repo is where they land, so you can follow along or take them home.

Prerequisites

To follow along live (or reproduce the build later) you'll need:

• Claude Code — installed and on a recent version.
• A GitHub account and the gh CLI — authenticated, for the issue → PR flow we drive from the terminal.
• Python 3.11+ with pytest — the deterministic parts get pulled out into scripts/, which are real Python with a real test suite (python3 -m pytest scripts/tests).

Repo structure

The artifacts are built live, so the layout fills in as the session progresses. Where to look:

• skills/ — the conditional behaviour, decomposed from the uber-prompt into discrete skills.
• scripts/ — the deterministic parts, pulled out as real code with tests.
• rules/ — the mandatory checks the workflow must enforce.
• the packaged plugin — everything above bundled into a single distributable you can take home.
