A source-linked directory and file template for repeatable coding tasks. Start with your workflow, then check its prerequisites before installing.
Sources checked September 12, 2026 · Not runtime certification.
A skill supplies task-specific instructions and supporting files. Codex can select it from its description, or you can mention it explicitly. Keep repository-wide instructions in AGENTS.md and use a skill for a repeatable task.
OpenAI skills documentationThese entries link directly to OpenAI’s catalog. Read the current instructions and scripts; inclusion here is not a guarantee of successful execution.
Work through PR feedback
Finds comments on the current branch’s GitHub PR, summarizes them, and asks which to address before making the selected fixes.
Before use: GitHub CLI authentication and repository access.
Read the source →Investigate failing CI
Inspects GitHub Actions checks and logs, explains the failure, then proposes a fix for approval. Other CI providers are outside its scope.
Before use: GitHub CLI authentication and readable Actions logs.
Read the source →Inspect a browser workflow
Uses Playwright CLI to navigate, fill forms, capture screenshots and debug UI flows. It does not promise a complete test suite.
Before use: Node.js/npm with npx; browser and wrapper setup described in the source.
Read the source →Use the bundled installer in an interactive Codex prompt. This is not a shell command:
$skill-installer gh-address-commentsOpen /skills inside Codex CLI, then try $gh-address-comments on a repository you can access. If missing, restart Codex. The installer defaults to ~/.codex/skills via CODEX_HOME; that differs from the documented personal folder for manually authored skills.
Create .agents/skills/review-export-change/SKILL.md in your repository, or ~/.agents/skills/review-export-change/SKILL.md for personal use. On Windows, ~ means your user home directory.
This original review-only template includes the required YAML name and description. Its body defines the task and output boundary.
---
name: review-export-change
description: Review a CSV export change for selected-row behavior and access-control regressions. Use when asked to review an export diff; do not use for unrelated changes.
---
1. Read the requested diff and the existing export behavior.
2. Check selected rows, empty selection, and permission boundaries.
3. Report concrete findings with file references and expected behavior.
4. State which checks were run and which remain unverified.
Do not edit files or claim a check passed without evidence.Try a disposable example diff containing an empty-selection defect. The review should identify the defect and say what was checked. Try an unrelated request to see whether the description is too broad.
Agent Skills format specification| Detail | Codex CLI | Claude Code |
|---|---|---|
| Project folder | .agents/skills/ | .claude/skills/ |
| Manual personal folder | ~/.agents/skills/ | ~/.claude/skills/ |
| Explicit invocation | $skill-name | /skill-name |
| Automatic selection | Matches the description | Matches the description |
Both use SKILL.md with YAML metadata. Shared instructions may transfer, but paths, tools and host-specific settings need checking. This is a format comparison, not a model-quality ranking.
Claude Code skills documentationReusable instructions in SKILL.md, with optional scripts and references. They describe a workflow; they do not grant accounts, permissions or tools by themselves.
Use .agents/skills/<name>/SKILL.md in a repository or ~/.agents/skills/<name>/SKILL.md for a personal skill. The bundled installer has its own destination; inspect its output.
Check the filename, YAML name and description, and repository location. Open /skills inside Codex CLI. If it remains absent, restart Codex and check again.
No. Discovery only confirms Codex can find it. Try one bounded task and inspect the actual output, permissions and verification evidence.
