Token cost

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.

Security

Grade A, and why

omx-setup 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 today.

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.

Origin

This is a copy

88% identical to omx-setup — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

OMX Setup

Use this task card to install or refresh OMX for the current project and/or user scope. Shared safety, lifecycle, hook, team, autonomy, and cancellation rules live in AGENTS.md. Do not infer new CLI behavior from this card; the implementation is authoritative.

Command and alternatives

omx setup [--force] [--merge-agents|--no-merge-agents|--clear-merge-agents-policy] [--dry-run] [--verbose] [--scope <user|project>] [--plugin|--legacy|--install-mode <legacy|plugin>] [--mcp <none|compat>] [--no-mcp|--with-mcp] [--disable-team|--enable-team|--team-mode <enabled|disabled>]
omx agents-init [path] [--dry-run] [--force] [--verbose]

Use agents-init for lightweight AGENTS.md scaffolding only, not a full install.

Supported setup options:

  • --force: overwrite/reinstall managed artifacts; transient, not persisted or replayed.
  • --merge-agents, --no-merge-agents, --clear-merge-agents-policy: exact bare selectors (no values/equals). Repeated identical selectors are idempotent; conflicting selectors fail before mutations. Set persists an explicit policy per invoking project root; clear removes it and cannot combine with a set. Merge refreshes managed sections; no-merge only suppresses that branch and is not a preserve mode.
  • --dry-run, --verbose: preview actions or show per-file/per-step detail.
  • --scope user|project: choose user (~/.codex, ~/.omx/agents) or project (./.codex, ./.omx/agents) targets.
  • --plugin / --legacy: select delivery mode; --install-mode legacy|plugin is the canonical scripted spelling. Conflicting mode flags fail.
  • --mcp none|compat (plus --no-mcp / --with-mcp): omit or enable first-party MCP compatibility and shared registry sync.
  • --disable-team, --enable-team, --team-mode enabled|disabled: select Team skill/context generation; conflicting selectors fail.

Resolve setup

  1. Scope: explicit flag, valid persisted ./.omx/setup-scope.json, TTY choice (default user), or non-interactive user. Legacy project-local migrates to project.
  2. Mode: explicit flag, persisted mode when retained, discovered ${CODEX_HOME:-~/.codex}/plugins/cache/**/.codex-plugin/plugin.json with name: oh-my-codex (plugin default), otherwise legacy. TTY reruns summarize saved choices and offer keep/review/reset; non-interactive runs do not block.
  3. Create required directories and atomically persist preferences only after successful setup.

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.
