Windows Installation Fix - Rate Limiting Solution

Hi Sam! I've been experiencing the same installation issues on Windows 11 with Git Bash and think I have identified the root cause and implemented a fix, thanks to Claude.

Problem Summary

The base-install.sh script was only downloading 1 out of 71 files, with the rest appearing as empty files or missing entirely. Multiple Windows users have reported this issue.

Root Cause

GitHub API/CDN throttling: When curl makes rapid successive requests, GitHub returns HTTP 200 responses with empty response bodies. This wasn't immediately obvious because the HTTP status codes indicated success, but the downloaded files were empty.

Solution Implemented

I've created a comprehensive fix that addresses multiple issues:

1. Rate limiting mitigation

   • Increased delay between downloads from 0.1s to 0.5s
   • Added retry logic with exponential backoff (1s, 2s, 4s delays)
   • Added empty file detection with [[ -s "$dest_path" ]]

2. Windows compatibility fixes

   • Fixed Python command detection (python3 vs python)
   • Fixed /dev/tty compatibility for Git Bash
   • Fixed carriage return handling in file paths

3. Bash scripting improvements

   • Fixed subshell variable scope issues using here-strings
   • Added verbose error logging with curl stderr capture
   • Improved error handling and retry logic

Testing Results

• Before: 1/71 files downloaded (1.4% success rate)
• After: 67/71 files downloaded (94% success rate)
  The remaining 4 files that occasionally fail are also affected by rate limiting and typically succeed on retry or with manual download.

Working Branch

I've implemented these fixes in a branch on my fork:
https://github.com/ImACodingFool/agent-os/tree/fix/windows-download-rate-limiting

The main changes are in scripts/base-install.sh with the download function completely rewritten to handle rate limiting and retries.

Next Steps

I'm happy to open a PR with [bug fix] in the title if Sam would like. I need to deploy this fix across 5 developer machines, so I wanted to share the solution with the community.

Let me know if you'd like me to create a formal PR or if you have any questions about the implementation!
