oh-my-codex is a workflow layer for OpenAI Codex CLI that adds prompts, agent teams, skills, hooks, HUDs, and other runtime assistance while leaving Codex as the execution engine. It is for people who use Codex CLI and want structured workflows and additional help as tasks become larger. The catalogue entries are its skills, hooks, and MCP integrations for those Codex workflows.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Excessive Agency · line 31 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.00386 |
| Opus 5 | $0.00009 | $0.00193 |
| Sonnet 5 | $0.00004 | $0.00077 |
| Haiku 4.5 | $0.00002 | $0.00039 |
Grade A, and why
ask scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Ask (Local Advisor CLI)
Use a locally installed external advisor CLI for focused questions, reviews, brainstorming, or second opinions. This skill replaces the separate ask-claude and ask-gemini skills.
Usage
$ask claude <question or task>
$ask gemini <question or task>
omx ask claude "<question or task>"
omx ask gemini "<question or task>"
Backend selection
- Use
claudewhen the user asks for Claude, Anthropic, or the previous$ask-claudebehavior. - Use
geminiwhen the user asks for Gemini or the previous$ask-geminibehavior. - If no backend is specified, choose the installed backend that best matches the user request; if neither is clearly available, explain that a local CLI is required.
Local CLI commands
Claude:
omx ask claude "{{ARGUMENTS}}"
claude -p "{{ARGUMENTS}}"
Gemini:
omx ask gemini "{{ARGUMENTS}}"
gemini -p "{{ARGUMENTS}}"
If needed, adapt to the user's installed CLI variant while keeping local execution as the default path. Do not silently switch to an MCP or remote provider when the local binary is missing.
Artifact requirement
After local execution, save a markdown artifact to:
.omx/artifacts/ask-<backend>-<slug>-<timestamp>.md
Minimum artifact sections:
- Original user task
- Backend and final prompt sent to the CLI
- Raw CLI output
- Concise summary
- Action items / next steps
Task: {{ARGUMENTS}}
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ask is a skill published in the GitHub repository Yeachan-Heo/oh-my-codex (33,024 stars, last pushed today), licensed MIT. It adds 18 tokens to every session and 386 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
