unionai-oss/hlock is a Rust tool that records the configuration of the agent execution environment in a lockfile so it can be rebuilt on another machine. The latest release is recorded as v0.5.0. The provided information contains no changes for this version, so nothing can be confirmed about the features added or modified in this release.
The tool is meant to collect models, MCP servers, skills, and settings in a single file, version them, and sync them across machines. According to the README summary, it pins settings, shows what changed, and provides commands that sync dependencies and run sessions or process prompts. It can record project settings only, or add personal settings on top, and it says sensitive values are kept as placeholders instead of the real values. It is a tool focused on recording the components of the agent environment in a lockfile so they can be reconstructed on another machine.
However, the README states that the project is in an early development stage and that compatibility may change. The provided record does not include the specific changes in v0.5.0, so it is not possible to judge what differs in this version. The GitHub star count is recorded as 5, but that figure alone cannot gauge the actual scope of use or the stability. The verifiable basis today ends at the feature of managing settings through a lockfile and the caveat that the project is at an early stage; long-term compatibility has to be checked separately.
