Test report

Verdict: Tested · Works
Score: 8.8/10
Tested: Aug 5, 2026
Environment: Claude Code 2.x (agent harness)

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Aug 5, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Ran the sync against a fixture holding one hand-written Codex skill and one stale synced copy: it refreshed the stale copy and left the hand-written file byte-identical, while the obvious `cp -r ~/.claude/skills/* ~/.codex/skills/` silently overwrote it and destroyed the content. The .synced-from-claude marker is what makes repeat runs safe, and the bundled list-skills enumerator installed to ~/bin and printed the synced library in both text and JSON form. The repo README still advertises the old symlink behaviour, which the current skill has replaced with real folder copies.

What Sync Claude Skills To Codex does

Copies your Claude Code skills — both plugin skills from ~/.claude/plugins/cache and personal skills from ~/.claude/skills — into ~/.codex/skills so Codex CLI sees the same library. A .synced-from-claude marker records which folders it owns, so re-runs refresh those and leave skills you wrote by hand alone. Triggers when you ask to share or re-sync a skill library between Claude Code and Codex, typically after installing or updating a plugin.
