Sync to codex

The process I experienced firsthand through the https://anthropic.skilljar.com/claude-code-in-action course using real-world daily projects

Install

npx -y skills add spideynolove/claude-code-in-action --skill sync-to-codex

Assembled from the repository path, not quoted from the project. Check it against their README if it does not work.

One thing to look at

2 stars2 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Sync Claude Code skills to Codex CLI and Qwen Code via filesystem symlinks. One source of truth at ~/.claude/skills/, symlinked into ~/.codex/skills/ and ~/.qwen/skills/. Respects targets: frontmatter field.

SKILL.md

1.6 KB, as published. Nobody here has run it

sync-to-codex

Syncs skills from ~/.claude/skills/ → ~/.codex/skills/ and ~/.qwen/skills/ using symlinks.

Both tools read plain markdown SKILL.md files from their own paths. No translation — the format is identical across Claude Code, Codex CLI, and Qwen Code.

~/.claude/skills/my-skill/SKILL.md   ← one source
         ↓ symlink
~/.codex/skills/my-skill/            ← Codex CLI reads this
~/.qwen/skills/my-skill/             ← Qwen Code reads this

The PostToolUse hook fires automatically after any Edit or Write to a .claude/skills/ file.

Manual sync

python3 ~/.claude/hooks/sync-skills-to-codex.py

Dry-run (preview, no filesystem changes):

python3 ~/.claude/hooks/sync-skills-to-codex.py --dry-run

Filtering with targets: frontmatter

---
targets: [claude, codex, qwen]   # all three
---

---
targets: [claude]                 # Claude Code only
---

Omitting targets: syncs to all tools by default.

Env overrides

SKILLSHARE_SOURCE=~/.claude/skills \
SKILLSHARE_CODEX_TARGET=~/.codex/skills \
python3 ~/.claude/hooks/sync-skills-to-codex.py

Manifest

~/.codex/skills/.skillshare-manifest.json and ~/.qwen/skills/.skillshare-manifest.json track managed symlinks. The prune step only removes symlinks it created — manually placed files are never touched.
