Coding Agent Change Digest

Turn your coding agent's diffs into human-readable change notes

Problem

V2EX users report shipping hundreds of thousands of lines and tens of thousands of commits with AI, across many projects, yet it's hard to quickly understand what an agent changed and why; a Hacker News Show HN project explicitly targets 'plain-English notes on what your coding agent changed', confirming diff review is no longer enough.

Solution

Connect to a Git repo or agent workspace and generate a structured digest after each commit or task: grouped by feature and file, flagged for risk, highlighting changed public interfaces and likely regressions, with daily or per-project changelog rollups.

Users

Individual developers and small teams who heavily use Claude Code, Codex, and similar coding agents, especially those maintaining multiple projects at once.

MVP

Watch a local Git repo or target directory; call an LLM to summarize diffs at module level; auto-flag API, database, and auth-related high-risk changes; produce daily or per-task summaries; export Markdown for PRs and records.

Revenue

Free local CLI plus a cloud subscription for multi-repo support, team-shared digests, and history archiving; charge by repo count or digest volume.

Why now

AI agents now produce code far faster than humans can read diffs, so comprehension is the new bottleneck; a solo dev can validate quickly with a local CLI plus LLM APIs.
