Order Intake with Retrieval from the Product Catalog
Order Intake with Retrieval from the Product Catalog
In use at: Butcher shop with its own production
Orders received by phone, email, and online shop are turned into verifiable orders for the inventory management system. A retrieval stage searches the catalog using fuzzy name matching, word coverage, product attributes, and the customer’s order history. The language model chooses only from these candidates and cannot make up a product number. If there is any ambiguity, the system asks for clarification.
Evidence: Adversarially tested: five review agents found 28 errors, each fixed with a regression test.
- Retrieval
- Language model with a fixed output format
- Candidate-only selection
- XML and EDIFACT for the inventory management system
AI Phone Agent with Tool Calls
AI Phone Agent with Tool Calls
In use at: Butcher shop (order intake), EMS studio in Hannover (appointment booking)
Handles conversations in German, answers follow-up questions, addresses objections, and enters orders or appointments directly. The behavior is defined in a campaign file rather than in the code, with CRM and inventory management connected through adapters. The agent identifies itself as AI at the start of the call.
- Language model with tool calls
- Real-time speech recognition and speech synthesis
- Campaigns in YAML
- CRM adapter

Summary
AI systems for real-world operation, not demos: agents with tool calls, retrieval that only works with supported candidates, and the automation around it, from data pipelines to monitoring. Every project in this overview has been delivered and is in use.
AI Agents in Use
Voice agent with tool calls at two clients. Behavior configured in campaign files instead of code, with CRM and ERP systems connected through adapters.
RAG Without Guessing
Retrieval over master data, where the language model only selects from supported candidates. If something is unclear, the system asks instead of guessing.
Test Like an Attacker
Multiple testing agents attack each system, and every finding becomes a regression test. Real-time inference with fixed latency requirements.
Operations and Automation
Azure in clinical use, Docker and Kubernetes, CI and automated deployment, and custom systems running continuously with monitoring.
