What it does
Yichen Codex Chatgpt is an agent skill from mcncarl/yichen-skills. Use the signed-in ChatGPT website in Chat UI Pro mode, never Work mode, to research, architect, and review one local project through a configured Secure Tunnel and read-only MCP, while Codex alone edits and tests locally. Trigger on explicit $yichen-codex-chatgpt, 让 ChatGPT 设计后由 Codex 写代码, ChatGPT 架构并审查 Codex, or requests for a Codex and ChatGPT collaboration loop. Pure research stays on the official ChatGPT website; code and hybrid work follow ChatGPT PLAN to Codex execution to ChatGPT REVIEW. Website control…
Its SKILL.md is about 3.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 21 other files, including reference files (for example `README.md`, `SECURITY.md` and `agents/openai.yaml`).
It sits in Productivity & Automation, covering Desktop control. It works with OpenAI and Model Context Protocol.

What it can do on your machine
Read from SKILL.md and the folder at commit 9bd7898. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Yichen Codex Chatgpt loads about 3.8k tokens when it runs, and up to ~32k if it reads all its reference files. Until then it costs about 192 tokens; SKILL.md has 1,869 words of instructions outside code blocks.
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
Auto-check passed
The automated check found no risky patterns in SKILL.md.
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); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,869 words (~3,822 tokens).
“Use the user's signed-in ChatGPT Chat UI with the active model route visibly labeled Pro as the researcher, architect, and reviewer. Codex is the only code writer and command/test executor.”
