Omx Setup

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 templates/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.

What setup changes

• Legacy mode installs prompts/native agents/skills and merges full config.toml.
• Plugin mode archives/removes legacy OMX-managed prompts/skills, refreshes installable native agent TOMLs and stale generated non-installable agents, and keeps setup-owned runtime hooks.
• Both modes verify Team CLI interop markers in built dist/cli/team.js, generate AGENTS defaults only when selected/allowed, and write ./.omx/hud-config.json; notification hook references are setup-owned outside plugin skill delivery.
• AGENTS.md is ./AGENTS.md. Without --force or --merge-agents, interactive runs ask before overwrite and non-interactive runs preserve it. Active-session safeguards may skip writes. Plugin mode may separately prompt for AGENTS and developer_instructions defaults; non-interactive runs preserve existing files.
• Plugin mode enables setup-owned runtime flags (plugin_hooks, goals, or legacy hooks/codex_hooks fallback). Project scope uses CODEX_HOME=./.codex unless explicitly overridden.

Verify

omx setup --force --verbose
omx doctor

Expect doctor evidence for prompts and skills in the selected scope, project-root AGENTS.md, .omx/state, and CLI-first config in the scope target config.toml. First-party MCP and shared registry sync are omitted unless setup used --mcp compat (if supported by the installed CLI).

If using local source, run npm run build before node dist/cli/omx.js setup --force --verbose and node dist/cli/omx.js doctor. If AGENTS was not overwritten or merged, stop the active OMX session and rerun with --force or --merge-agents; do not edit lifecycle state manually.

Discovery troubleshooting

If $omx-setup is absent/stale: run omx setup --verbose, then omx doctor; verify ./.codex/skills/omx-setup/SKILL.md for project scope or ${CODEX_HOME:-~/.codex}/skills/omx-setup/SKILL.md for legacy user scope. In plugin mode verify the oh-my-codex plugin is installed/discovered. For duplicates, inspect historical ~/.agents/skills overlap and follow doctor/setup cleanup guidance.

Exit contract

Report selected scope/mode, dry-run versus mutation, AGENTS policy, affected roots, and doctor indicators. Stop only after setup completes successfully and verification identifies the expected files/config; on failure preserve the exact command output and rerun the smallest corrective command. Do not claim installation from a dry-run alone.
