Mineral Line

A companion app for StarCraft: The Miniatures Game. Army lists, live game tracking and every rule, on a phone and on the iPad at the side of the table. I built it solo, directing a team of agents.

What it does

Free, works offline and needs no account. On iPhone, iPad and Android, in alpha.

Game tracker

Score, resources, supply, mission markers and unit health on one screen, with undo for every action.

Linked games

Two players link by QR code. Both phones and a table display stay in sync, and spectators can follow.

Army builder

Checks that a list is legal as you build it, and shares it by QR code, game code or PDF.

Rules

Search the full core rules, or ask in plain language and get an answer that cites the rule.

Stats

Win rate, margins, faction matchups and mission results over any period.

Tournaments

Chess clocks, official scoring and mission drafting for store nights. In progress.

Linked live

Two players link their phones by QR code, and a table display joins as a spectator. A change on one device reaches the others through a Cloudflare Durable Object, one per game. This is the demo from the app's own site, running live.

Screens

How it was built

Every piece of work goes through the same loop. The lit steps are mine.

ScopeI write the issue: what to build, what's out of bounds and how I'll judge it.me

QuestionsThe orchestrator asks what it can't infer, on the issue. I answer there.agent, then me

PlanIt posts an implementation plan as a comment.agent

ApproveI read the plan and change the approach where it's wrong. Nothing is built without the label.me

BuildWorker agents build in parallel, each in its own worktree, with tests.agents

DemoEach pull request arrives with phone and tablet screenshots and recordings.agents

Red-teamI run an adversarial review across five lenses and decide which findings get fixed.me, with review agents

Test and mergeI run it by hand on a real phone and tablet. Then I merge, or send it back.me
