What is h5i?
Traditional version control tracks only the final code diffs, leaving gaps in understanding the reasoning behind AI-generated changes. h5i addresses this by storing additional metadata such as model details, read files, and risk assessments alongside regular commits. The system supports multi-agent coordination through typed messages for reviews and handoffs, while keeping raw outputs separate to reduce unnecessary data in active contexts. Audit functions apply rule-based checks to flag potential issues like secret leaks before changes are merged. Integration happens via simple commands that enhance existing Git operations, allowing PR reviews to include full provenance without requiring new infrastructure or altering core repository structures.

What you can use h5i for
AI Commit Provenance Tracking
Capture every AI-generated commit with full context including prompts, models, agents, tests, and audit results stored in Git refs without altering source history.
Multi-Agent Coordination
Enable typed messaging between agents such as Claude and Codex using append-only channels in refs/h5i/msg for reviews, handoffs, and risk flags that travel with the repository.
Auditable Sandboxed Execution
Run agents in confined environments with deterministic policy checks while storing large outputs out-of-band to reduce token usage and support reproducible audits.
