The Lantern
and the Promise
with Claude



A fictional story. This story is based on SM’s journey with AI. St. Brigid School and everyone in it are made up. The bumps and the lessons are real.
Who did what. Michelle Cho and Jorge Ledezma chose the story, wrote the character sheets and picture descriptions, directed and approved every change, and checked the facts against SM’s documents. Claude, an AI model made by Anthropic, drafted and revised the words from our notes. Gemini, an AI image model made by Google, generated every picture; none were drawn by hand. When a picture was wrong, we asked for a new one.
Our AI use level: AI-Enhanced. Using SM’s faculty AI guidelines, we place this book at AI-Enhanced: part of the content was generated by AI, and we disclose it. The cover names Claude as a co-writer; in a formal citation, AI is cited as a tool, not an author.
We take responsibility. We are responsible for everything in this book, including the parts made with AI.

still learning to do the walking.


One day, a lantern came to St. Brigid School.
It glowed, and it could make things.
If you told it what you wanted, it made it.
A poem. A picture. A whole story!
The kids found out first.
The grown-ups did not know what to think.

Miguel wanted to give his grandma a poem.
So he asked the lantern.
Whoosh! It wrote one, fast and fancy.
"Did you write this?" Grandma asked.
Miguel looked at his shoes. "The lantern did."
Grandma hugged him anyway.
But Miguel felt funny inside.
The words were pretty. They were not his words.

The grown-ups got worried.
They hung up a big sign: NO LANTERNS!
But lanterns still glowed at home.
And nobody had learned how to use one well.
The sign said NO.
It did not say HOW.

A visitor brought a machine called the Sniffer.
"It beeps when kids use the lantern," he said.
Beep! Beep! It beeped at Ava's story about a fox.
But Ava wrote that story herself!
Ava cried. Her mom and dad were upset.
"A beep is not the whole truth," said Mrs. Ortega, the principal.
"We will talk with our kids first."

"I cannot fix this alone," said Mrs. Ortega.
So she asked for help.
Teachers, kids, moms, dads, and Father Tom sat in a circle under the big oak tree.
Everyone got a turn to talk.
"Let's stop saying NO," said Mrs. Ortega.
"Let's start learning to KNOW."

Every class is different.
So each teacher hung a sign with three colors.
Green: the lantern can help.
Yellow: ask first.
Red: this one is all yours.
Now everyone knew the rules, one room at a time.

On Thursdays, the teachers ate lunch and learned together.
Mr. Lee asked the lantern about Saint Brigid.
"She rode a dragon to school," it said.
Everyone laughed. That was not true!
So they looked it up in a real book.
Now they always check what the lantern says.
All summer, they changed their lessons, so the work asks kids to think.

The kids had an idea of their own.
"Don't try to catch us," they said. "Trust us."
So they wrote a promise:
My work shows my own effort.
I follow my teacher's lantern rules.
I tell the truth about my helpers.
"Trust is the glue that holds us together," said Ava.
Promise Keepers helped everyone remember.

The promise went on every paper, every day.
Soon Miguel signed it without even reading it.
Scribble, scribble.
Mr. Lee noticed. "Read it out loud, Miguel," he said.
Miguel read it slowly. His cheeks got warm.
"A promise only counts," said Mr. Lee, "if you mean it."

One day Ava crossed her arms.
"Just tell me what to write!"
Mr. Lee knelt down beside her.
He did not give her the answer.
"The hard part is where your brain grows," he said.
"The lantern can light the path. But your feet have to walk it."
Ava stayed in at recess. She tried, and tried again.
Then she got it. All by herself.

After school, the teachers spread the kids' work across one big table.
They held up the lantern, and its light helped them see.
Five kids were stuck on the same step!
The next day, Mr. Lee taught that step a new way.
The lantern did not do the kids' work.
It helped the teachers help the kids.

Father Tom told a story from the Bible.
"Long ago, people built a tall tower to make a big name for themselves.
They stopped understanding each other, and they never finished it.
But God's people build a city together, where God is at home with us.
Here, we build that city in each of you.
We grow the whole you: your heart, your mind, and your soul.
Your heart is the ground. Without it, nothing else can stand.
A lantern can build a tower fast. It cannot grow a person."
"Let's build the city," said Miguel.

Miguel wrote a new poem for Grandma.
It was short. It was a little messy.
And every word was his.
Grandma read it twice. Then she hugged him tight.
On the shelf, the lantern glowed softly.
It was a helper, not the boss.

Under the oak, the whole school kept building, one brick at a time.
"Are we done?" asked Ava.
Mrs. Ortega smiled. "Not yet. We are still building."
The lantern can light the way.
But you have to do the walking.
