yc-software/qm is a multiplayer agent harness in which multiple agents share a single workspace to collaborate on work. A harness is a structure that binds several agents to one workspace and runs them together. The implementation language is TypeScript and the license is MIT. The latest release recorded in the repository is v0.1.15. However, the provided FACTS list no items that were newly added or changed in this version.
According to the README, qm is a multi-user agent work environment that organizations operate themselves. It can be used together in Slack and on the web through the same harness, and it separates workspaces and memory, permissions, and automatic execution per user and per conversation channel. You can choose among several harnesses and models, while deployment settings and security policies are managed by the organization. In other words, the core of this repository is a configuration that binds Slack and web collaboration into one harness and draws the boundaries of permissions and memory at the level of the user and the conversation channel. The repository was created on 2026-07-29, and the recorded star count is 15455, but no reference point in time is given.
However, the provided FACTS contain no performance measurements, no adoption cases, and no comparison material against other harnesses. The scores are recorded as novelty 7.0, technology 7.0, quality 8.0, and momentum 9.1. The configuration described in the README can be read, but there is no validation material showing how well permissions and memory are actually separated in a multi-user environment. So while it is worth taking a look at the way it organizes organization-level agent collaboration, whether it can actually be used is better judged after reading the release notes and operational records a bit further.
