**Agentic Provenance for AI-Assisted Development**

*diachron* (from Greek *dia* "through" + *chronos* "time")

Diachron automatically tracks every code change made by AI coding assistants, creating a queryable timeline of your project's evolution.

The Problem

When AI agents like Claude Code make changes to your codebase:

Git commits contain technical jargon you may not understand
The AI's reasoning and intent isn't captured anywhere
You lose visibility into when bugs were introduced or features built
There's no human-readable narrative of what happened

The Solution

Diachron uses **Claude Code 2.1's hook architecture** to transparently capture every file modification. No manual logging required.
