Mastra released the open-source software factory Mastra Factory Beta, which connects GitHub, Linear and Slack and runs agents in phases according to a configurable kanban board, with each phase settable to manual or automatic. The company says that since the alpha version launched in July, Factory has automated 25-35% of PRs and closed 50-60% of issues, and the project receives more than 100 issues and merges about 200-250 PRs per week. The team also introduced a graph-based wiki knowledge base, AgentController session management and the Signals real-time correction mechanism, and plans to release the knowledge graph as an independent primitive.
