Share a Codex session

Use the bundled script at ../../scripts/share_session.py.

1. Verify gh auth status succeeds.
2. Run the script without --push, passing the user's description after --description. This creates a local Markdown preview and prints its path.
3. Tell the user that transcripts can contain source code, prompts, tool inputs, local paths, or secrets. Ask them to approve publishing after they review the preview.
4. Only after explicit approval, rerun with the same description and --push.
5. Return the GitHub URL printed by the script.

If no repository is configured, ask for owner/repo, then run:

python3 ../../scripts/share_session.py --configure-repo owner/repo

Configuration is stored in ${CODEX_HOME:-~/.codex}/share-plugin-config.json. CODEX_SHARE_REPO overrides the file.

Never publish without the preview and explicit approval. Do not expose transcript contents in chat unless the user asks.
