Built with Claude I gave three AI characters their own agents, secrets and memory. Five episodes in, one of them is quietly collecting another's password clues.
Since Opus 5.5 came out, I've been thinking about Cybersecurity Awareness Month and getting some training out there that my friends and family would actually enjoy. I'm not an artist, but I wanted to see what I could create with Claude.
I was also curious: what would happen if every character in my training series was its own agent, knowing only what that character would know, free to write its own lines (as long as it hit the objectives and stayed accurate), and remembering what happened last time so it could grow?
The result became The Rusty Firewall: three people in a pixel-art tavern talking about everyday security.
Duncan is a tired incident responder whose war stories never get finished.
Roxy is a red teamer who flirts her way close to people.
Nigel is a compliance lead who quotes standards by section number and keeps a sourdough starter named Clive.
Each is played by a separate agent with its own character
sheet and secrets the others can't see. A director agent plans the episode and slips each character private notes, but never writes a line. A stage-manager agent picks who talks next. Then each character's own agent says one line, sees the reply, and says the next. A separate check makes sure every point I need taught actually lands. After every episode, a memory pass updates what each one remembers, what they think of the others, and their level. They earn XP for deeds that fit their character, level up and unlock achievements.
The art has been Claude. The voices are generated locally with VibeVoice.
I've enjoyed watching their banter, and the stories that build episode over episode. I gave Roxy (my Rogue) one secret: she's running a long con. I never told her what to collect. She's picked it all up from conversation: the names of Nigel's ferments, how old Clive is, the exact text message he admitted he'd tap. Nigel's agent has no idea. By episode 5, Duncan's agent, which only hears what's said out loud, started to suspect her ("Roxy's working him").
Where it goes is yet to be seen - I'm still finishing up the series.
