My Bookkeeper AI Agent Does a Much Better Job Than Me
Short summary
Developer built Chaser, an AI agent that reads AR spreadsheets daily and drafts polite collection emails scaled by invoice age. A separate "Tone Guardrail" agent blocks unethical requests like legal threats, demonstrating multi-agent safety patterns. 30-minute build with transparent, auditable architecture.
- •Chaser agent manages overdue invoices, drafts tone-scaled reminders, never auto-sends—review-before-send workflow
- •Separate guardrail agent enforces ethical boundaries by blocking legal threats, credit damage, ultimatums
- •Architecture pattern: keep agent logic focused and delegate compliance checks to independent single-purpose agents
Generated with AI, which can make mistakes.
