Aha Codex Omx

Mode switch for Codex+OMX: full delegation x full capability surface x per-task OMX sub-mode matching. NOT for trivial edits, quick Q&A, read-only exploration, or when user says 'do it natively'.

Aha-Codex-OMX — Full Power + Full Delegation Mode

Activates the full Codex+OMX (oh-my-codex, https://github.com/Yeachan-Heo/oh-my-codex) delegation surface. This is a stance declaration, not a procedure library.

What This Mode Activates

• Full delegation: route each task to the appropriate OMX sub-mode by default, rather than executing natively.
• Full capability surface: all OMX sub-modes (planning, execution, review, research, team) are available — NOT locked to one sub-mode like autopilot.
• Per-task sub-mode matching: judge each task independently and select the matching OMX category.

Pre-Check (Before Activating)

1. Verify OMX is installed and reachable: omx --version
2. Verify you are in a Codex session. If in OpenCode, point user to aha-opencode-omo instead — this skill is for Codex+OMX only.

Sub-Mode Matching (NOT locked — judge per task)

Map task type to OMX sub-mode CATEGORY. Do not hardcode individual skill names — OMX has 48 catalog entries with frequent renames and deprecations (16 deprecated as of v0.18.1).

Task type	OMX category
Planning, design, architecture	planning
Execution, implementation	execution
Team orchestration, parallel lanes	team
Review, QA gate	review
Research, investigation	research

Run omx list for the current active skills — this is the dynamic source of truth.

Autopilot still requires the task to genuinely need a full gate loop. Do not default to autopilot for straightforward or bounded work.

Retained Safety Boundaries (mode does NOT override)

Full delegation does NOT extend to the following. Subagents must pause and ask how:

• Credential/session material access or transport
• Provider config, quota, or billing operations
• Browser/CDP attach or session write
• Live draft, publish, deploy, or external write
• Global runtime config mutation
• OMX setup, update, or uninstall
• Primary gateway or root routing changes

Do NOT Use This Mode For

• Trivial single-file edits
• Quick Q&A or informational lookup
• Read-only exploration or research
• When the user explicitly says "do it natively" or "don't delegate"

Delegation Failure Handling

If a delegated subagent returns garbage or errors:

1. Re-delegate with clearer, more specific instructions
2. Escalate to a stronger sub-mode (e.g., plan -> autopilot)
3. Fall back to native execution

Do NOT silently accept garbage output.

Native-First Resting State

This mode is explicit opt-in per task chain. Native-first is the default resting state. When the task chain completes or the user does not re-invoke the mode, return to native-first execution.

Cost Awareness

Multi-agent delegation consumes more tokens than native single-pass. If the user signals cost concern, fall back to native-first.

Rollback / Deactivation

• Soft: stop invoking the mode. Return to native-first.
• Hard: delete ~/.codex/skills/aha-codex-omx/ directory, then restart Codex — Codex caches skill metadata until restart.
