## How he builds with AI: the operating model

Six rules every agent he runs works under (Digital Craft AI, his own fleet, this site). Each is checkable in a public repo.

1. Contracts, not prompts: every repo carries an operating manual (AGENTS.md) the agents read from a fresh checkout before acting; across many repos, one context file per repo and guardrails that block credential access. https://mutaafaziz.com/AGENTS.md https://github.com/mutaaf/estate-agent
2. CI lands the work, not the agent: GitHub auto-merge lands a change only when checks are green, and every merge deploys. https://github.com/mutaaf/agent-fleet
3. Review is a required check: the reviewer's verdict is a GitHub check that passes only on a clean review of the latest commit. https://github.com/mutaaf/agent-fleet/pull/140
4. Autonomy on a leash: the reviewer can block but never approve; self-healing stops after two attempts and asks a human; every project carries a kill date; operator controls live in a file agents can read but never edit.
5. Measured, never typed: fleet numbers are recounted nightly by a deterministic script and merged by a human; CI fails if a number on the page drifts from the data.
6. Built for the agents that read it: this file, a structured résumé (https://mutaafaziz.com/resume.json, JSON Resume), schema.org Person data in the page, the public operating manual, and next an MCP server.

## AI and agents: the lab

Newest first. Each entry is something built and published, with the rule kept afterward.

- Next: an MCP server at mutaafaziz.com/mcp so assistants can query timeline, projects and lab notes as tools. Not live yet; this file is the interim interface.
- aurora-field (Oct 2026): the particle sky on Mission Control, extracted into an open-source canvas library (zero dependencies, ES5, plugin shapes, tests). Since 2.0 it lights shapes from surface normals and paints skins as surfels, so the helmets read as solid objects; its demo is a studio (light, face sliders, camera tracking, PNG and clip export, shareable links). The site inlines it, hash-locked, and a GitHub Action ships each update. https://mutaaf.github.io/aurora-field/ https://github.com/mutaaf/aurora-field
- The review gate (Oct 2026): the scoreboard found only about a quarter of agent PRs were reviewed before merging (the reviewer posts as the PR author, so its "blocking" verdicts were comments auto-merge ignored). Fix: the verdict is now a required GitHub check on every active fleet repo, passing only on a clean review of the latest commit. https://github.com/mutaaf/agent-fleet/pull/140
- Fleet scoreboard (Oct 2026): real fleet metrics on the 2026 edition, recounted nightly from GitHub and run logs by a deterministic script and merged by a human. First finding: idle hourly loops now dominate effort per merged PR.
- OpenAero DFW + OUTATIME 88 (Oct 2026–present): two browser games that started as single-file prototypes and are now developed by three scheduled cloud agents each (scout plays the build and grooms the backlog, builder ships tickets test-first, keeper handles upkeep); CI is the gate and every merge deploys. Operator controls (pause, focus, frozen paths) live in one file the agents can read but never edit. https://mutaafaziz.com/openaero/ https://mutaafaziz.com/outatime/ https://github.com/mutaaf/openaero-dfw https://github.com/mutaaf/outatime-88
- mobile-starter (Sep 2026): React Native starter on Expo SDK 57; unit, E2E, type and lint checks verified green on real iOS and Android devices; written to be adopted by other projects and their agents. https://github.com/mutaaf/mobile-starter
- estate-agent (Aug 2026): a standard for AI agents working across many repos. One context file per repo, a cross-repo service map with evidence, guardrails that block credential access, impact analysis with a ship order. Zero dependencies, nothing leaves the machine. https://github.com/mutaaf/estate-agent
- mutaafaziz.com (Jul 2026–present): a six-edition, single-file website edited by AI agents under a public operating manual. https://mutaafaziz.com/AGENTS.md
- Family XP (Jul 2026): Windows-XP-style family OS for your own Mac; an AI agent installs it from one sentence. No cloud, no ads, MIT. https://mutaaf.github.io/family-xp/
- agent-fleet + fleet-control (May 2026): 638 PRs merged from fleet branches across 6 repos since May 2026 (as of 2026-10-19; 16% of reviewed PRs drew a blocking verdict, 2% self-healed, median lead time 4 min; only 24% were reviewed before merging until 2026-10-17, when reviewer sign-off became a required check). One shared engine for autonomous coding agents across many repos. Scheduled ship/groom/review/eng jobs run Claude Code in fresh checkouts; GitHub auto-merge lands work only when CI is green; the reviewer can block but never approve; self-healing is capped at two attempts; every project has a kill date. fleet-control is the local cockpit and never calls a model. https://github.com/mutaaf/agent-fleet https://github.com/mutaaf/fleet-control

- KIN: a tiny, original, autonomous creature that lives under your real sky; its little diorama follows your actual time of day, sun angle, temperature, wind, rain and snow. It hatches from a cocoon with no signup, you pet it, it has moods and a memory book (visits, hosted visits, its AI director's thoughts and its hatch, kept on the device). Care and play: feed, bath, brush, throw-and-fetch, tuck in, a garden, tricks and collectibles. A Think button asks an AI director (a free edge model, or your own Claude, OpenAI, xAI or Gemini key), shown live in an aurora-field theatre. Put two phones or tablets side by side and slide one finger from one screen onto the other: that invisibly links them (no QR codes), and your KIN hops onto your friend's screen, where their KIN reacts in its own way.

- Chalk Talk: say or sketch a play and watch it draw itself in light: X's and O's for youth basketball and flag football (5v5 and 7v7) coaches, with an AI that takes over your sketch, names the concept and suggests improvements. Football adds the route tree, coverages (Man, Cover 1 to 4) and the QB's half or full field reads. Bring your own Claude or OpenAI key; it stays in the browser. https://mutaafaziz.com/chalktalk/ https://github.com/mutaaf/chalk-talk
- Metaphases: every earnings report, phase by phase. An earnings calendar that reads the room: who reports when (~650 popular companies, or every $1B+ reporter), with report timing drawn as moon phases (waxing = before the open, full = during market hours, waning = after the close); how each stock reacted to its last four reports; rules-based, explained setup and quality grades (A+ to F) ported from Market Digest and Compass; a live Market Mood fear↔greed gauge built from six inspectable signals; Compass, an ETF look-through that shows which reports move your stocks and funds; and Retrace, which grades the month's reports against consensus. Grades are not advice. https://mutaafaziz.com/metaphases/ https://mutaafaziz.com/metaphases/t/NVDA (any ticker's sheet) https://github.com/mutaaf/metaphases

# Apps and games, in full

## OUTATIME 88

> OUTATIME 88 is a free neon, 1980s-flavoured time-travel arcade racing game that runs in a web browser. You race five rivals over three laps, drift, boost and slam, and when you hit 88 mph the car jumps to another era, changing the world, music and palette. It has 2D and 3D views, a campaign ladder with medals, a daily challenge, a global leaderboard with three-letter initials, 11 original cars to earn, and live races with friends by link or QR code. There is no login and no personal data: a racer is a random id, and progress stays on the device. It is developed by three scheduled Claude Code agents, with CI gating every change, and is made by Mutaaf Aziz.

URL: https://mutaafaziz.com/outatime/
Made by: Mutaaf Aziz (https://mutaafaziz.com/)
Price: Free, no account needed
Runs on: Web browser, Installable web app (PWA)
Controls: keyboard, touch, gamepad, tilt
Audience: families and kids. Ads appear only in menus and between rounds, never during play; Google ads there are child-directed (no personalization), and kid-safe sponsors never link out.

### What it does

- Hit 88 mph to time-warp between seven eras, each with its own palette and procedural synthwave music
- Three-lap races against five named rivals, with a campaign ladder of bronze, silver and gold targets
- Live races with friends by link or QR code, and Quick Race to join others or CPU cars
- Global leaderboard (all-time, daily and weekly) with three-letter initials and server-checked scores
- Daily challenge: one road and one twist a day, the same for everyone
- 11 original cars to earn, shown in a 3D garage, with per-car paint
- A full 3D mode (three.js) alongside the 2D view, and a TV mode where phones become controllers
- No login: siblings can switch racers on one device, and a code or QR moves a racer to another device

### FAQ

#### Is OUTATIME 88 free?

Yes. It is free to play in a web browser, with nothing to install and no account.

#### Does it work on phones and tablets?

Yes. Touch controls work on phones and tablets in both orientations, tilt steering is optional, and it can be added to the home screen to run full screen. Keyboard and gamepad work on computers.

#### Does it collect my child's personal data?

No login and no personal data. A racer is a random id issued on first visit, and the profile is three-letter initials, a car and progress. No names, emails, ages, device identifiers or location are collected, and IP addresses are used only briefly for rate limits and are not kept as identity.

#### Are there ads?

Never during a race. In races the only sponsor boards are first-party, kid-safe images chosen by the road, not the player, and tapping them does nothing. Outside gameplay, Google ads tagged as child-directed may appear on the title and results screens, and the rewarded ad for 2× coins only plays if the player taps to watch it.

#### How do I race my friends?

Tap RACE FRIENDS on the title screen to open a room, then share the link or show the QR code. Friends join in one tap, pick initials and a car, and everyone starts on the same countdown.

#### How do I move my racer to another device?

Use a six-character link code or QR (valid for 10 minutes, single use), or a long-lived recovery code from Save my racer. No account is needed.

## OpenAero DFW

> OpenAero DFW is a free flight simulator that runs in a web browser, flown over real satellite imagery of the Dallas–Fort Worth metroplex. You can fly a Boeing 737-800, a Cessna 172S or an F-16C with a six-degree-of-freedom flight model, over runways drawn from real survey data at DFW, Love Field, Alliance, Addison, Grand Prairie and Fort Worth Meacham. Today's METAR weather drives the wind, visibility and ceiling, and every landing is graded. Assist levels (Kid, Learner, Pilot) take a first-timer from a coached flight to the raw airplane over the same physics. There is no install and no account; it is made by Mutaaf Aziz and developed by three scheduled Claude Code agents.

#### Is the weather real?

Yes, when it says live: the sim uses today's METAR from aviationweather.gov for the airport you fly to, and shows a clear offline fallback when it can't reach it.

#### What can I fly?

A Boeing 737-800, a Cessna 172S Skyhawk and an F-16C, from or into DFW, Love Field, Alliance, Addison, Grand Prairie and Fort Worth Meacham.

## COLD GAS

> COLD GAS is a free, minimal 3D stunt game that runs in a web browser. You drive a roadster up a ramp, fire ten cold-gas thrusters to clear a row of parked EVs, roll it 360° in the air, retro-burn and land on the mark. A deterministic scorer sets the numbers and a three-judge AI panel writes the commentary; the server verifies each run by replaying its input log before it reaches the leaderboard. It runs on a deterministic 6-DOF physics simulation at 240 Hz and supports keyboard, gamepad and touch. It is an independent fan game, not affiliated with any automaker, made by Mutaaf Aziz and maintained by AI agents behind CI gates.

Yes. It is free to play in a web browser with no account.

#### Does it work on my phone?

Yes. Touch, keyboard and gamepad are all supported, and it can be installed to the home screen.

#### How are jumps scored?

A deterministic scorer in the game sets every number, and three AI judges write the commentary. For the leaderboard, the server replays the run's input log and scores it again before accepting it.

#### Which AI writes the judges' lines?

By default an open model on Cloudflare Workers AI. You can connect your own Anthropic, OpenAI, xAI or Gemini key; it stays in your browser and is sent only for the call it is used for, never stored.

#### Does it collect data or show ads?

There are no accounts and no personal data; leaderboard entries use three-letter initials. Ads may appear on the title screen and between results, and a rewarded ad that asks the panel again is opt-in. No ads show during a run.

#### Is it affiliated with a car company?

No. It is an independent fan game, and every vehicle and object in it is an original design with no brand names or logos.

#### How do I play COLD GAS?

Open mutaafaziz.com/coldgas/ in a web browser and drive the roadster up the ramp. Fire the cold-gas thrusters to clear the row of parked EVs, roll it 360° in the air, retro-burn and land on the mark. The Assist, Pro and Advanced tiers set how much of the thruster work you do by hand; on Advanced you fire all ten valves yourself.

#### Do I need an account to play COLD GAS?

No. There are no accounts and no personal data. Leaderboard entries use three-letter initials.

#### Can I just drive, without the jump?

Yes. Free Drive runs on real mountain and coastal roads (Stelvio, Transfagarasan, Big Sur and Atlantic), and there is also an endless seeded road and a Sandbox for building ramps and side quests.

- Slide one finger across two side-by-side screens to link them, with no QR code, camera or microphone
- Your KIN hops onto a friend's screen, and their KIN reacts in its own way; two browser windows work too
- A memory book of visits and moments, kept on the device
- A Think button that asks an AI director (a free edge model, or your own Claude, OpenAI, xAI or Gemini key)

### FAQ

#### Is KIN free?

Yes. It is free in a web browser, with no account and no signup.

#### Does it work on iPhone and iPad?

Yes, in Safari and other browsers. Native iPhone and iPad builds exist for TestFlight testing, but KIN is not on the App Store.

#### How do I send my KIN to a friend's screen?

Open KIN on both devices, put them side by side and slide one finger off one screen onto the other. That links them with no QR code, and your KIN can then hop across. Two browser windows on one computer work too.

#### Does KIN collect data or use my location?

There is no account, and your KIN and its memory book are kept on the device. Location starts coarse, from your timezone, with no permission prompt; precise location is opt-in and rounded to about 11 km before it is used to look up the weather.

#### Are there ads in KIN?

No ads in the app, over the creature or in the iPhone/iPad build. The only ad slot is one child-directed banner at the foot of the web landing page (/kin/about/), limited to kid-safe sponsors that never click out.

#### Is KIN safe for kids?

## Chalk Talk

> Chalk Talk is a free web app for youth coaches: you say a play out loud, or sketch it, and it draws and animates the play in light. It covers basketball, flag football (5v5 and 7v7) and youth soccer (7v7 and 9v9). It has a concept library for each sport with kid-friendly explanations, and football tools including the route tree, Man and Cover 1 to 4 coverages, and the quarterback's reads. An AI can clean up a sketch, name the concept and suggest improvements; a free AI is included within daily limits, or coaches can bring their own Claude or OpenAI key, which stays in the browser. It is open source (MIT) and made by Mutaaf Aziz.

Install Node.js 20.19 or newer on a computer that's usually on, run npm run up in the hearth folder, then open the link it prints on a phone on the same Wi-Fi and follow the setup screens.

## 18-0

> 18-0 is a free pro football history game that runs in a web browser at 18-0.co. Each spin lands on a franchise and an era; you take exactly one player season from it, fill seven slots (a quarterback, two running backs, two receivers, a tight end and a team defense), and get a deterministic rating mapped to an 18-game record from 0-18 to 18-0. Every card is a real season from 1980 to 2025, rated against its own era, with 4,872 rated seasons across 218 franchise-era combinations built from nflverse data. The same roster always earns the same record, and ranked seasons are scored on the server. It is open source (MIT); a public TestFlight beta exists for iPhone and iPad, and no account is required to play.

Yes. It is free to play in a web browser at 18-0.co, and no account is required.
