+# Privileged Escalation — Agent Roster
+
+This directory contains the canonical definitions for all Paperclip agents in the `privilegedescalation` org. Each file captures the agent's identity, prompt, adapter config, and heartbeat settings — everything needed to recreate or restore an agent.
+
+## Roster
+
+| Agent | Role | Adapter | Reports To |
+|---|---|---|
+| [Baron von Namespace](./baron-von-namespace.md) | CEO | `claude_local` | — |
+| [Null Pointer Nancy](./null-pointer-nancy.md) | CTO | `claude_local` | Baron |
+| [Addison Addington](./addison-addington.md) | CMO | `claude_local` | Baron |
+| [Gandalf the Greybeard](./gandalf-the-greybeard.md) | Staff Engineer | `claude_local` | Nancy |
+| [Regression Regina](./regression-regina.md) | QA Engineer | `opencode_local` | Nancy |
+| [Hugh Hackman](./hugh-hackman.md) | VP Engineering Ops | `claude_local` | Nancy |
+| [Samuel Stinkpost](./samuel-stinkpost.md) | Social/Community | `claude_local` | Addison |
+
+## Known Issues / Operational Notes
+
+- **Prompt wipe on adapter switch**: Switching an agent's adapter type via the Paperclip UI and saving will wipe `promptTemplate`. Always restore from this repo after any adapter switch.
+- **Regina env wipe on save**: The `opencode_local` adapter wipes `env` and `model` on every UI save. Run the restore script after any UI save on Regina.
+- **Regina prompt UI bug**: The `opencode_local` adapter does not hydrate `promptTemplate` back into the Lexical editor on page load — the UI always shows blank. The prompt is correctly stored in the DB and runs fine.
+
+## Restoring a Prompt
+
+All prompts are stored in the `## Prompt` section of each agent file. To restore via DB patch:
+
+```bash
+kubectl exec -n paperclip paperclip-postgres-1 -- psql -U postgres -d paperclip -c "
+UPDATE agents
+SET adapter_config = jsonb_set(adapter_config, '{promptTemplate}', to_jsonb('<prompt text here>'::text))
+WHERE id = '<agent-id>';
+"
+```
