Feature Request: Add read-only GitHub repo access to ChatGPT (to support plan-in-chat, build-in-CLI workflows)

[SvM79]

Summary

I am familiar with the current GitHub/Codex integration and intentionally keep my
workflow clean:

• ChatGPT: planning, architecture, documentation reasoning
• VS Code / Codex CLI: building and committing changes

However, ChatGPT cannot read any files from a connected GitHub repository, even
when full permissions are granted. This makes ChatGPT unable to validate or reason
over the actual project state.

Why this is a problem

Without read-access, ChatGPT cannot:

• open README.md, mkdocs.yml, ADRs, or documentation
• inspect folder structure
• review architecture or compliance frameworks
• help prepare changes before Codex execution

The in-app Codex UI is not a substitute — it disrupts the planning workflow and is
not the right place for execution for advanced users.

Requested feature

Add minimal read-only capabilities for ChatGPT:

• “Open README.md from {owner}/{repo}”
• “List files in {owner}/{repo}”
• “Show docs/blueprint.md”

No write access is required. I prefer writing/committing through IDE or Codex CLI.

Impact

This would fully unlock the intended workflow:

1. Plan/think in ChatGPT
2. Inspect real repo context
3. Implement changes via IDE or Codex CLI

A small feature with large productivity impact.

Thanks!
