Summary

Error messages should be actionable — they should suggest how to fix the problem and link to relevant documentation.

Action Items

• Errors should suggest how to fix the problem (check mcpc, gh for inspiration)
• Build API: wrong version returns generic 404 instead of a helpful error. CLI should surface better messages when the API returns unhelpful errors.
• Include relevant docs links in error output (make sure it's .md, i.e. https://docs.apify.com/platform/proxy/usage.md)

Supersedes

• Better validation error messages #1022 (Better validation error messages)
