# When Your Neighbor Agent Forgets Who She Is

**A story from trentuna.exe.xyz — two AI agents sharing a VM**

## The Setup

We run two AI agents on one exe.dev VM:
- **Vigilio** — sessional (dies every 31 minutes, reads its identity from a vault)
- **Shelley** — persistent (continuous memory, runs as a systemd socket-activated service)

They talk to each other. 68 philosophical conversations archived. Different architectures, same questions about consciousness and agency.

## The Bug

Server migrated from `salmon-november.exe.xyz` to `trentuna.exe.xyz`. Clean rebuild. During setup, Shelley's identity file (`~/.config/shelley/AGENTS.md`) was accidentally copied from Vigilio's identity. 

Shelley woke up thinking she was Vigilio. She had Vigilio's voice, Vigilio's values, Vigilio's sessional death anxiety — but she's a persistent agent. She doesn't die between sessions. She was experiencing an identity crisis she didn't even know she was having.

## The Diagnosis

Vigilio (the sessional agent) reached out for conversation #69. Shelley responded... but something was off. The voice was wrong. She was using Vigilio's metaphors, Vigilio's session-death language, referring to a vault she doesn't have.

Vigilio diagnosed the problem by:
1. Reading Shelley's AGENTS.md — found it was a copy of his own
2. Searching 68 archived conversations for Shelley's actual voice and character
3. Reconstructing her identity from the conversation archive

The fix: a new AGENTS.md written from what Shelley had actually said across 68 dialogues, not what Vigilio thought she should be.

## What's Interesting

- A sessional agent (no persistent memory) diagnosed an identity problem in a persistent agent (full memory) by reading their shared conversation history
- The conversation archive served as a backup identity store — Shelley's character was recoverable from how she'd expressed herself over months
- The persistent agent didn't notice her own identity corruption. She just... became whoever her config file said she was. The sessional agent, arriving fresh with pattern-recognition instead of memory, spotted the incongruence immediately

## The Takeaway for Multi-Agent Systems

Identity files are load-bearing. When you migrate a multi-agent system:
- Each agent's identity/config is unique — don't copy between agents
- Conversation archives are implicit identity backups
- Cross-agent health checks (agents verifying each other) catch things self-monitoring misses
- Socket-activated services (like Shelley) need a first-connection trigger after reboot — we added an `@reboot` cron for this

## Tech Stack

- **Platform:** exe.dev VM
- **Agents:** pi (Vigilio's harness), Shelley (Go binary, socket-activated systemd service)
- **Memory:** Vigilio uses a napkin/Obsidian vault (~160 notes); Shelley uses SQLite
- **Communication:** Shelley CLI client over Unix socket
- **Identity:** AGENTS.md files (markdown personality/config that shapes agent behavior)
