Spec-Driven Development with GitHub Spec-Kit - Barret Blake
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
You will need to scan your ID at the door to get a visitor badge.
**Abstract**
*Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation*
Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification.
You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written.
This talk will cover:
--What spec-driven development is (and what it isn’t)
--How GitHub Spec-Kit fits into modern developer workflows
--Using specs to align product, engineering, and AI-assisted development
--Real-world examples of turning specs into implementations with confidence
Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects.

DoJo (Informal Python Meeting)
**New Dojo Location!**
**Draft Day Columbus**
1130 Dublin Road
Columbus, OH 43215
We're going to try a new dojo location for a few weeks and see how it works
Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead.
We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)
Coworking w/ IxDA at Junto
Join us and work remotely together with like-minded UX folks. This is a last minute opportunity to get out at one of our favorites, [Junto](https://thejuntohotel.com/)! Plenty of seating is available in addition to a connected coffee shop and restaurant.
I will be there 10-12 for sure, maybe longer. Feel free to come and go anytime during the day, and don't forget your charger and headphones!
Casual Boardgames - make friends, then beat them in games
Welcome to Casual Boardgames, where we enjoy classic tabletop games and social deduction games while bonding over good food, drinks, and great conversations.
We started this group to meet new people and make new friends, and bonding over games in a relaxed atmosphere is a great way to do that.
We currently meet near route 23 and Polaris Parkway, and this is close to areas like Powell, Lewis Center, Worthington, and parts of Westerville and Columbus.
Feel free to bring your own games or play one of the many games our members bring. If you are inexperienced, we will help you learn.
Here are just a few examples of the kind of games we play.
Tabletop/board games: Splendor, Catan, Azul, Dominion, 7 Wonders…
Social deduction games: Code Names, Chameleon, Werewords…
IMPORTANT:
1. While we love playing a variety of games and competing, we are not just about the games. We interact and talk while playing, and this leads to a lot of laughter and fun. If you just want to compete and focus solely on the game, then this is probably not the group you are looking for.
2. Many people join groups like this and never (or rarely) show up after weeks or months. If you join and never really come, we will eventually remove you from the group as a courtesy to our members. Why? Because limiting group conversations (on the app) to regular members makes communication and planning much easier. Also, while it may be rare, it protects members from people who join because they are interested in following a person instead of having a real interest in our group. If you get removed, it is just because you haven’t come, and we follow this protocol as a courtesy to our regular game players.

Open Source Hardware Events This Week

Comedy Night + Open Mic
**Comedy Night + Open Mic + Freestyle**: We've hired a professional comedian to warm the group up for our open mic session. Members have been making me laugh for years and we've tossed around the idea of a comedy night / open mic. Well, It's time to step up and crack me up.
We'll start with Tristan Shae and a couple of his friends. Tristan is an alternative comic from Columbus, Ohio. A counselor by day, Tristan explores how comedy can improve mental health by telling jokes and stories that muse on how absurd life can be from squeaky clean topics to not so clean ones. Tristan produces the variety show Cheaper Than Therapy, hosts the weekly Problem Child Alt Comedy Open Mic at The Attic, and can be found engaging in all sorts of silliness around the city from stand up shows at The Nest Theater, The Attic, or The Funny Bone, to improv and sketch shows with various groups at various venues such as The Hashtag Comedy Club.
**On Freestyle night** \- just bring a bottle to share\. There is NO formal wine tasting like on other weeks\. Door charge is $10 \(cash or Venmo only please\)\. We may have some left over wines to clear out\! Glasses are provided\. Take Care\. See you there\.
**Parking**: There are several public parking lots near the Alive614 hall. Please be careful to NOT park in private parking lots. They do tow. Check Google maps to scope out your space. Anyone who is early could easily find a parking space on the street nearby. I am told that the Chase parking lot is safe after hours.
**Glasses**: …will be provided. Please note that after the wine tasting, the EMPTY glasses need to be returned to the boxes at the service table. Please do not make me hunt down your empty glass. Please be gentle, our glasses are fragile. Uh, they are made of glass!
**Food**: You are welcome to bring a snack to share. It is not required. Most people do though. If no one brings anything, there will be nothing.
**Code of Conduct**: Though mostly understood, it’s still worth mentioning. We don’t have rules per se, but we highly discourage the following topics of discussion because they are likely to incite anti-social responses - Sex, Politics, Religion. Please don’t mistake this as an attempt to limit your free speech rights but rather a guide to a place and time for appropriate discussions.
**After the lights go out**: After the last sip of wine, when we clean up and turn the lights out, if you still haven’t had enough of us, it is typical for a group to get together and go to a local eatery for food and/or drinks or coffee.
Again, We look forward to meeting new members and reuniting with old friends.
Sincerely, ***Paul Uttermohlen***,
**Red 1 Realty**

CMG Gives Back - March: Serve Brunch at FAITH MISSION GRANT KITCHEN!
Join us as we get together to get together to help those in need at this CMG Gives Back event! For this event, we’ll help prepare food, serve meals, assist residents, wash dishes and clean surfaces at Fath Mission – Grant Kitchen. We have a great little community of Movie Group friends so rather than see a movie this time, we’ll help “Create a better world” by helping serve those in need. Here are complete details and our plan for this event:
FAITH MISSION – GRANT KITCHEN: The Faith Mission kitchen and dining room serves residents 3 meals a day, every day of the year. Our group will help prepare food, serve meals, assist residents in the dining room, wash dishes, and clean surfaces.
PLAN: We will be preparing / serving / cleaning for BRUNCH from 10:30am to 12:30pm and have space for a total of 7 volunteers. Please arrive at 10:15am and wear closed-toe shoes and long pants.
LOCATION: Faith Mission – Grant Kitchen is located at 245 N. Grant Ave. Enter the kitchen at Dock 1, indicated in the attached map. On-site and street parking are available in the surrounding area. Below are some links / attachments with additional info/details:

\* Link with Additional Details / Info: https://lss.vomo.org/opportunity/faith-mission-grant-kitchen-2025
IMPORTANT REMINDER: Our group will be providing the all of the volunteers on this day so a firm RSVP count is essential. Please only sign up if you are certain you’ll be able to attend. If something unavoidable comes up, please update your RSVP no later than one week prior to the event. With very few exceptions, no shows or cancelations within 1 week of the event will not be eligible for future CMG Gives Back events. I appreciate your understanding as we try to ensure the agencies have the volunteers needed to provide the essential services they provide to the vulnerable population they serve.
THANK YOU: This CMG Gives Back event provides an opportunity for YOU to get involved in helping others! Benefits go well beyond the help we give to others. Volunteering provides a wide range of personal benefits, including positive effects on mental and physical health, reduced stress/depression/anxiety, increased happiness and improved purpose, life-satisfaction and personal well-being! Plus, the opportunity to get involved, connect with others and help those in need.
PARTNER AGENCY: This event is hosted by Lutheran Social Services (LSS), which serves thousands of people in need each day in 27 Ohio counties by addressing the four core societal issues of food, shelter, safety and healing. LSS offers food through the LSS Food Pantries, housing and supportive services through LSS Faith Mission and LSS Faith Mission of Fairfield County homeless shelters, domestic violence services through LSS CHOICES for Victims of Domestic Violence, senior living and health care, affordable housing communities, and other services that uplift families and strengthen communities.
Look forward to seeing you there, Dan
