What Codex does

Codex runs OpenAI Codex/GPT models through the Codex CLI to autonomously implement code, review changes, and review plans. Use it when delegating coding tasks, getting a second-opinion review, or running tasks in sandboxed modes.

Codex is cataloged under AI Engineering on DirSkills. Codex comes from a repository tagged agentic-ai, agents, ai, claude-code and claude-code-agents.

Frequently asked about Codex

  • What else does feiskyer publish alongside Codex?

    Codex is one of 12 skills that DirSkills catalogs from feiskyer/claude-code-settings, the repository it ships in. Its siblings there include Brainstorming, Deep Research and Fix GitHub Issue. Each one is a separate skill with its own page in this directory, installs the same way Codex does, and is maintained by feiskyer in that same repository. The rest of the collection is listed on the feiskyer/claude-code-settings page.

  • How does Codex compare to other AI Engineering skills?

    Codex ranks #948 by stars among the 2451 AI Engineering skills in this catalog. The most-starred ones next to it are Architecture Decision Records, AI-First Engineering and Agentic OS. DirSkills ranks by the star count of the repository each skill ships in, so that order reflects how popular those repositories are rather than any review of Codex against them. Open each page to compare what they document and how they install.

Brainstorming

Brainstorming explores user intent, requirements, and design options through collaborative dialogue before implementation. It is used before building new features, components, or systems when design decisions are involved, not for bug fixes or tasks with an obvious implementation path.

Deep Research

Deep Research orchestrates multiple headless claude -p subprocesses to split a research goal into parallel sub-goals, gather sources, and aggregate findings into a polished report file. Use it for systematic web research, competitive analysis, batch link processing, or evidence synthesis.

Fix GitHub Issue

Fix GitHub Issue guides analysis, branch creation, implementation, testing, and PR submission for a reported issue. Use it when working from an issue number, issue URL, or a request to fix an issue end to end.

GPT Image

GPT Image generates and edits images using OpenAI GPT Image API models (gpt-image-2, gpt-image-1, etc). Use it when the user explicitly asks for OpenAI or GPT image generation or editing.

Grill Me

Grill Me runs high-intensity adversarial design reviews and grill sessions, challenging assumptions and missing constraints before implementation. It also maintains a domain model with a terminology glossary and ADRs as decisions crystallize.

Handoff

Handoff compresses the current conversation into a handoff document, saved to $TMPDIR, so a new agent can continue the work seamlessly. Use /handoff when handing off a session to another agent or after a long conversation.
