## Summary

- Remoco, built in-house by Japanese healthtech company Ubie, is an internal platform where instructions, a model, and tools are bundled and defined as an AI agent, which people call up on the web or in Slack to do work. The CTO explains that development is just one of several uses.
- The isolated environment where agents run code holds no credentials. External requests go through a proxy, and authentication is attached only for allowed destinations. Ubie said this lets it assign tasks without approval.
- Agents are split into personal ones that run with an individual's permissions and team ones shared in Slack. Team agents read data only through accounts for each information category, matched to the range of channel participants, which prevents management information from being exposed in shared channels.
- The development agent Uvin handles implementation and bug fixes, and the legal agent handles first-line response to contract review 1. The CTO introduced a loop in which both agents analyze the previous day's records and produce improvement proposals.
