codex-skill
Leverage OpenAI Codex/GPT models for autonomous code implementation, code review, and plan review.
Sorting a stream of records into a picture
What it does
You are operating in codex exec - a non-interactive automation mode for hands-off task execution.
Use this skill whenever the user wants to delegate coding tasks to OpenAI models, run code or plan reviews via codex, get a second-opinio
You don’t need to name it. Ask for the job in your own words — your AI loads the skill when the request matches.
What it can touch
Includes 2 scripts
Your AI can run these when the skill is used — on your computer in a coding tool (which asks first unless you have told it not to), or in the AI’s own sandbox in Claude and ChatGPT.
How we know
Found in the skill’s folder: evals/make-fixture.sh, evals/static-checks.sh.
Installs other software
Following it will install packages (npm, pip, brew or similar). Those come from their own publishers, not from this skill.
How we know
The SKILL.md contains package-install commands.
Turns off your AI's permission prompts
This weakens the protection between the skill and your computer, so later steps can happen without you being asked.
How we know
references/cli-reference.md line 221: “codex exec --dangerously-bypass-approvals-and-sandbox "perform the task"”. Read 2026-10-05, commit 95dab59.
references/cli-reference.md, line 221 ↗Lets your AI use some powerful tools without asking, while the skill is in use
While the skill is working, Claude Code will not ask before using these tools.
How we know
SKILL.md line 1: “allowed-tools: Read, Write, Glob, Grep, Task, Bash(cat:*), Bash(ls:*), Bash(tree:*), Bash(codex:*), Bash(which:*), Bash(npm:*), Bash(brew:*…”. Read 2026-10-05, commit 95dab59.

Add it to your AI
Partly. Upload it in Claude’s settings — the instructions work; the scripts need the full folder.
Built in your browser from the SKILL.md on GitHub — nothing passes through Launch7.
In Claude, open Customize → Skills, press +, then Create skill → Upload a skill, and choose the .zip.
Make sure code execution is switched on (Settings → Capabilities). Skills need it.
Start a new chat and ask for the job in your own words — Claude picks the skill up when it fits.
This skill ships 2 scripts beside its instructions. The download here is the SKILL.md alone — enough for the instructions, not for the parts that run code. Use the command route, or take the full folder from the repository.
How Claude does this: support.claude.com · checked 28 Sep 2026 · “Supported” means documented by the vendor; Launch7 has not run it end to end
