What it does
Codex CLI Specialist is an agent skill from borghei/Claude-Skills. OpenAI Codex CLI and cross-platform skill authoring. Use when setting up Codex CLI, converting or syncing skills between Claude Code and Codex, configuring agents/openai.yaml, or validating cross-platform skill compatibility.
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including scripts, reference files and assets (for example `assets/openai-yaml-template.yaml`, `references/best-practices-and-troubleshooting.md` and `references/codex-cli-guide.md`).
It sits in Agent Workflows, covering Skill authoring. It works with OpenAI. The repository describes itself as: 385 AI skills, 77 expert agents, and 900 stdlib Python tools for every team: engineering, PM, marketing, C-level, compliance, business ops, research, and a LinkedIn toolkit… The licence is MIT.
When your agent uses it
- Setting up Codex CLI
- Syncing skills between Claude Code and Codex
- Configuring agents/openai.yaml
- Validating cross-platform skill compatibility
Example prompts
- “/codex-cli-specialist”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit c9a1487. 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
Ships 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python
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
Codex CLI Specialist loads about 1.8k tokens when it runs, and up to ~15k if it reads all its reference files. Until then it costs about 62 tokens; SKILL.md has 697 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); the scripts in this folder are not scanned.

Codex CLI Specialist
The agent converts Claude Code skills to Codex-compatible format, validates cross-platform compatibility, and builds skill registry manifests. It generates agents/openai.yaml configurations from SKILL.md frontmatter, runs 17 compatibility checks across both platforms, and produces skills-index.json for discovery systems.
Core Capabilities
- Skill conversion — turn a Claude Code SKILL.md into a Codex-compatible skill by generating
agents/openai.yamland copying scripts/references/assets. - Cross-platform validation — run 17 checks across Claude Code, Codex CLI, and shared categories (frontmatter, openai.yaml, encoding, naming, size).
- Index building — scan skill directories and emit a
skills-index.jsonmanifest for registries, discovery, and version pinning. - Codex CLI setup & operation — install, configure API access, and run with the right approval mode (suggest / auto-edit / full-auto).
- Dual-target authoring — write skills that work on both platforms from one shared
scripts/,references/,assets/tree. - Distribution & sync — keep Claude Code and Codex in sync via shared repo, CI/CD conversion, or git hooks; publish via GitHub releases.
When to Use
- Setting up or operating OpenAI Codex CLI.
- Converting or syncing skills between Claude Code and Codex.
- Configuring or reviewing
agents/openai.yaml. - Validating a skill for dual-platform compatibility.
- Building a
skills-index.jsonfor a skill library.
Clarify First
Before converting or building, confirm these inputs. If any is unknown or vague, ASK — do not assume:
- Task — convert a skill, validate cross-platform compatibility, or build a skills index (selects
codex_skill_converter.pyvscross_platform_validator.pyvsskills_index_builder.py) - Source path — the SKILL.md or skill directory to operate on (the input the scripts read)
- Strictness — strict validation mode and whether to fail on warnings (sets
--strictand the pass/fail gate)
Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.
Tools

References
Load the reference that matches the task — keep this file lean and pull detail on demand:
- references/workflows.md — Quick Start, Tools Overview, the 5 core workflows (install, author, convert, validate, build index), Common Patterns, and deep per-tool parameter/output reference. Read when running a workflow or needing exact tool arguments.
- references/configuration-and-distribution.md —
agents/openai.yamlstructure, discovery/locations, invocation patterns, cross-platform patterns, frontmatter compatibility, install/versioning, and sync/CI/CD/GitHub distribution. Read when configuring openai.yaml or distributing a library. - references/best-practices-and-troubleshooting.md — best practices (authoring, Codex usage, cross-platform, performance), anti-patterns, troubleshooting table, and success criteria. Read before shipping or when a tool misbehaves.
- references/codex-cli-guide.md — full Codex CLI reference: installation, configuration, approval modes, skill system, invocation, built-in features, environment variables.
- references/cross-platform-skills.md — writing skills for multiple agents (Claude Code, Codex, Cursor, Copilot, Goose): platform comparison, universal structure, per-platform config files, template.
- assets/openai-yaml-template.yaml — production-grade Codex config template (instructions, tools, model selection, versioning).

Scope & Limitations
This skill covers:
- Installing, configuring, and operating OpenAI Codex CLI
- Converting Claude Code SKILL.md files into Codex-compatible format with
agents/openai.yaml - Validating skill directories for dual-platform (Claude Code + Codex CLI) compatibility
- Building skill registry manifests (
skills-index.json) for discovery and distribution
This skill does NOT cover:
- Writing the actual domain logic inside Python tool scripts (see senior-fullstack, code-reviewer, or the relevant domain skill)
- Cursor, Windsurf, Cline, or Aider platform-specific configuration (see standards/ and root-level dotfiles like
.cursorrules,.windsurfrules) - OpenAI API key management, billing, or rate-limit troubleshooting (out of scope -- refer to OpenAI documentation)
- Automated testing or CI/CD pipeline authoring beyond skill validation (see senior-devops and templates/)
Integration Points
| Skill | Integration | Data Flow |
|---|---|---|
| code-reviewer | Convert code-reviewer's SKILL.md to Codex format so it can run in Codex CLI | codex_skill_converter.py reads code-reviewer's SKILL.md and generates agents/openai.yaml |
| senior-fullstack | Validate fullstack skill's cross-platform compatibility after adding Codex support | cross_platform_validator.py checks both SKILL.md frontmatter and openai.yaml structure |
| senior-devops | Embed skill validation and index building into CI/CD pipelines | DevOps workflows call cross_platform_validator.py --strict --json and skills_index_builder.py as pipeline steps |
| tech-stack-evaluator | Evaluate whether Codex CLI fits a project's AI tooling stack | Tech stack evaluator references Codex CLI capabilities and configuration patterns from this skill |
| senior-architect | Architect multi-agent skill systems that span Claude Code and Codex CLI | Architect uses cross-platform skill patterns and index manifests to plan skill distribution |
