Account-synced Personal Skills across ChatGPT and Codex devices

Feature request

Provide an account-bound Personal Skills library shared by ChatGPT and Codex. It should behave
like browser bookmark sync: after signing in on another computer or supported product surface,
the user's skills should become available without manually copying or reinstalling local files.

Problem

Local filesystem skills are machine-bound, and Personal Skills may require separate installation
across product surfaces. Durable personal workflows therefore become unreliable when users
change computers or move among ChatGPT, Codex desktop, CLI, and IDE.

Users should not need to teach the same stable workflow repeatedly or maintain independent
copies on every device.

Expected behavior

1. Bind Personal Skills and ownership to the OpenAI account.
2. Sync canonical skill content across supported ChatGPT and Codex surfaces.
3. Make an installed personal skill available after sign-in on a new device.
4. Propagate updates automatically or through an account-level update policy.
5. Provide version history, source, enable/disable state, rollback, and conflict handling.
6. Allow personal, workspace, product, and project scopes.
7. Preserve sandbox, approval, plugin, connector, and workspace policy boundaries.
8. Clearly report unsupported dependencies instead of silently ignoring a skill.
9. Support export/import using the Agent Skills format without making manual import the primary

synchronization mechanism.

Acceptance test

1. Create and enable a Personal Skill on computer A.
2. Sign in to the same OpenAI account on computer B.
3. Start a new supported ChatGPT or Codex session.
4. Confirm the same skill version and enablement state appear without copying files or installing

it again.

1. Update the skill on computer A.
2. Confirm computer B receives the new version, shows update provenance, and can roll back.

Current limitation

OpenAI's current Skills documentation says Personal Skills must be added separately on desktop
and web/mobile and do not automatically sync across those surfaces:
