Requirements

• Python 3
• Node.js

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Identify the requested pack slug. If the user gives a vague style, list available packs and pick the closest match.
2. 2Run scripts/fetch_skin_pack.py unless the user already has a local pack folder.
3. 3Inspect the staged folder. It must contain theme.json, background.png, and preferably README.md.
4. 4Apply the staged pack through the user's active Codex theme manager or Codex Dream Skin workflow. Do not modify app.asar, signed…
5. 5Verify the Codex Home, Task, Diff, and Composer states for readability. If a live UI check is not possible, say that clearly and provide…
6. 6Always finish with the restore path: use the active theme manager's restore command or restore the default Codex appearance from the…

What it can do on your machine

Read from SKILL.md and the folder at commit 9e7b281. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 1 file in scripts/ (Python), which the agent can run.

  Shell commands in SKILL.md call:

  • npx
  • python3

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Codex Skin Pack Installer loads about 978 tokens when it runs. Until then it costs about 134 tokens; SKILL.md has 354 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~134

When it runs · the whole SKILL.md, loaded when a task matches

~978

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description

Install Codex themes and Codex skin packs with npx skills. Use this skill when a user wants Codex to find, download, validate, apply, switch, remix, or restore Codex desktop themes such as caishen-readable, caishen-lite, mythic-guardian-noir, global-founder-bright, export-night, or caishen-max. It stages verified public-safe theme packs from ChannelerH/codex-skin-packs, checks theme.json/background.png, preserves the native Codex layout, avoids private workspace screenshots, and provides restore guidance.

npx skills add ChannelerH/codex-skin-packs --skill codex-skin-pack-installer --global --agent codex --yes

python3 "$CODEX_SKILL_DIR/scripts/fetch_skin_pack.py" caishen-readable

python3 "$CODEX_SKILL_DIR/scripts/fetch_skin_pack.py" --list

Apply the Codex skin pack staged at STAGED_PATH.
Use the active Codex theme manager or Codex Dream Skin workflow.
Keep the native Codex layout interactive.
Do not upload private workspace screenshots.
Verify Home, Task, Diff, and Composer readability.
Tell me the restore path before finishing.

Restore my Codex desktop theme to the default appearance.
Use the active Codex theme manager's restore path.
Verify the sidebar, home screen, task view, diff view, and composer are back to readable native styling.
Do not modify app.asar or the signed application bundle.
