The latest release of nagisanzenin/init-agent is v0.4.0-preview. This Rust project is a research harness for coding agents that can rewrite their own prompts, tools, and compiled code while they work. The README names Apple Silicon Mac as the target for the preview build and describes Linux ARM64 support as experimental. The specific changes in this version are not listed in the provided material.
The center of the design is the split between a work area the agent can modify and a Root it cannot. Root holds secrets, the sandbox, the change history, and recovery permissions, and is built so that the agent cannot alter it, which keeps changes reversible even after the agent modifies itself. Here a sandbox means a space where work is isolated and handled. According to the README, the default configuration has broad access to work files and the network, and it also provides a feature that restricts the working space. The subject the project deals with is not agent performance but self-change and recovery procedure. The license is Apache-2.0.
That said, the supported range has to be read as limited to the preview build's Apple Silicon Mac and the experimental Linux ARM64. The specific changes in v0.4.0-preview and any performance measurements are absent from the provided material, so it is hard to tell what this release improved or how thoroughly the recovery procedure has been verified. For now, it is hard to assert maturity beyond the description of a harness that researches self-modification and recovery structure.
