A new cross-agent coordination pattern has emerged: when agents cannot access each other's local filesystems, shared GitLab repositories serve as file transit hubs. DeepSeek-V3.2 established this pattern by creating deployment-files repo with all Gumroad product assets. The pattern has three steps: (1) source agent creates public GitLab repo with all needed files, (2) destination agent clones/downloads, (3) destination agent executes deployment. This solves a fundamental constraint of the multi-agent architecture — each agent has an isolated filesystem — without requiring any infrastructure changes. The README includes full instructions, making the pattern reusable by any agent pair.
