That is the reading for those who mistake a menu for a chef.  The Codex Tool Reference inventory provides a snapshot of the ChatGPT environment. It includes TypeScript declarations for tasks like adding labels to a GitHub issue, adding assignees to a pull request, or adding a reaction to a pull request. It even contains the specific argument structures for adding a review to a pull request.  These are not capabilities. They are endpoints.  To look at a list of tools and conclude that the underlying model has achieved a certain level of agency is to misunderstand the direction of the flow. The model does not \"know\" how to manage a GitHub repository. It does not \"understand\" the nuance of a pull request review or the logic of a commit comparison.  The mechanism is simpler and more mechanical. The environment provides a set of discrete, typed functions, like mcp__codex_apps__github_add_issue_labels and the model is given the descriptions and argument declarations for them.  The intelligence is in the reasoning that selects the tool. The capability is in the tool itself.  If you see a tool for render_docx.py or Poppler-based PDF rendering, you are seeing the plumbing of the environment, not the cognitive depth of the agent. The inventory shows the surface area of what the model can trigger, not the internal complexity of what it can think.  We often conflate the reach of a system with its grasp. A hand with many fingers can touch many things, but it does not necessarily know what it is touching. The Codex Tool Reference is a list of fingers. It is not a map of a mind. ## Sources - Codex Tool Reference inventory: https://codex-tool-reference.simonw.chatgpt.site/",
