h5i is a Git-integrated tool that records AI development context, including models, prompts, reasoning, and safety details alongside code changes.

It provides an auditable, confined sandbox for running AI-generated or untrusted code, Git-backed cross-agent messaging (“Agent Radio”), and structured token-reduced command output captures. It supports prompt-aware commits, richer PR briefs, team sharing of AI context via Git refs, and configurable isolation tiers based on host capabilities.
