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.

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 | $0.00014 | $0.01788 |
| Opus 5 | $0.00007 | $0.00894 |
| Sonnet 5 | $0.00003 | $0.00358 |
| Haiku 4.5 | $0.00001 | $0.00179 |
Grade A, and why
configure-notifications scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Configure OMX Notifications
Use this card for Discord, Telegram, Slack, generic command aliases, or OpenClaw. Shared safety, lifecycle, hook, team, autonomy, and cancellation rules live in templates/AGENTS.md.
1. Inspect and choose a path
CONFIG_FILE="$HOME/.codex/.omx-config.json"
if [ -f "$CONFIG_FILE" ]; then
jq -r '{notifications_enabled:(.notifications.enabled // false), discord:(.notifications.discord.enabled // false), discord_bot:(.notifications["discord-bot"].enabled // false), telegram:(.notifications.telegram.enabled // false), slack:(.notifications.slack.enabled // false), openclaw:(.notifications.openclaw.enabled // false), custom_webhook_command:(.notifications.custom_webhook_command.enabled // false), custom_cli_command:(.notifications.custom_cli_command.enabled // false), verbosity:(.notifications.verbosity // "session"), idleCooldownSeconds:(.notifications.idleCooldownSeconds // 60), reply_enabled:(.notifications.reply.enabled // false)}' "$CONFIG_FILE"
else
echo "NO_CONFIG_FILE"
fi
Use AskUserQuestion to choose: Discord native (webhook or bot), Telegram native (bot token + chat id), Slack native (incoming webhook), custom_webhook_command, custom_cli_command, cross-cutting settings, or disable all notifications.
2. Native providers
Collect and validate provider values, then write only these native keys: notifications.discord, notifications["discord-bot"], notifications.telegram, or notifications.slack. Do not represent native providers with generic aliases.
3. Generic aliases
For custom_webhook_command, collect URL, optional headers, method (POST default or PUT), events (session-end, ask-user-question, session-start, session-idle, stop), and an instruction template:
jq --arg url "$URL" --arg method "${METHOD:-POST}" --arg instruction "${INSTRUCTION:-OMX event {{event}} for {{projectPath}}}" --argjson headers "${HEADERS_JSON:-{}}" '.notifications=(.notifications//{enabled:true})|.notifications.enabled=true|.notifications.custom_webhook_command={enabled:true,url:$url,headers:$headers,method:$method,instruction:$instruction,events:["session-end","ask-user-question"]}' "$CONFIG_FILE" >"$CONFIG_FILE.tmp" && mv "$CONFIG_FILE.tmp" "$CONFIG_FILE"
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.

configure-notifications is a skill published in the GitHub repository Yeachan-Heo/oh-my-codex (33,078 stars, last pushed today), licensed MIT. It adds 14 tokens to every session and 1,788 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.
