Project name: Open Source Snapshot One liner: An automated snapshot-and-docs workspace for tracking and studying fast-moving open-source coding-agent projects. Stack: Git, Git submodules, GitHub Actions, Markdown docs, Claude Code GitHub Action, shell scripting. Problem: Keeping up with rapid upstream changes across multiple coding-agent repos is high effort, so this project centralizes updates and maintains structured docs for easier learning and comparison.

📷 Open Source Snapshot

I'm obsessed with open source—I think it's the greatest resource for learning how software actually gets built. This repo is my way of keeping tabs on my favorite projects so I can study and learn from them.

Starting with agentic coding tools, but planning to expand to other categories over time.

How it works

Each project gets a snapshot: submodules pointing to the upstream repos, plus architecture breakdowns and documentation I maintain.

• Submodules live under src/coding-agents/ and point to upstream repos
• GitHub Action runs every 3 days to pull latest changes
• If a submodule has 5+ new commits, Claude Code incrementally updates its manual docs under docs/coding-agents/<submodule>/ using .prompts/doc-gen-manual.md
• Docs commit directly to main

Manual trigger: Actions → "Update submodules & docs" → Run workflow

Open to suggestions on how to make this more useful—ideas and PRs welcome.
