Before running any shell snippet below, define this resolver in the same shell.
It accepts only Python 3.12 or newer, prefers python3 and then python, and
uses uv as the final fallback. Call ouroboros_python directly and quote every
argument passed to it; the function preserves arguments and heredoc/stdin input.
Only the probe and child interpreter discard inherited CPython path-selection
overrides; the caller shell keeps its environment unchanged.

PYdefault deliberately sends no model pin to Codex; it does not name a model
called "default". Confirm that the rewrite succeeded before recording the
decision. If this step is interrupted before the marker is written, the next
readiness check recognizes the partial gpt-5/default state and offers the
migration again.

fiIf Codex setup is required, ask one concise question in the user's language. This includes a user who has an existing Ouroboros configuration for another runtime. For a Korean conversation, use:
{
"questions": [{
"question": "Ouroboros를 처음 사용하시네요. 시작하기 전에 실행 환경을 설정할까요?",
"header": "Ouroboros 시작하기",
"options": [
{
"label": "설정하고 시작하기 (권장)",
"description": "한 번만 설정하면 바로 사용할 수 있어요"
},
{
"label": "나중에",
"description": "지금은 기본 안내만 보고 나중에 설정할게요"
}
],
"multiSelect": false
}]
}ouroboros setup --runtime codex when the executable
is installed. For a Marketplace-plugin-only install, use
uvx --isolated --python '>=3.12' --from 'ouroboros-ai[mcp]' ouroboros setup --runtime codex
instead.
In Claude Code, follow ../setup/SKILL.md. Do not ask the user to copy a
command when the current host can run it.After successful Codex setup, immediately ask:
{
"questions": [{
"question": "설정이 완료됐어요. 기본적으로 Codex에서 선택한 모델을 사용합니다. 모델은 언제든 나중에 바꿀 수 있어요.",
"header": "준비 완료",
"options": [
{
"label": "바로 시작하기 (권장)",
"description": "기본 모델로 바로 작업을 시작해요"
},
{
"label": "직접 모델 설정하기",
"description": "단계별로 모델을 바꾸거나 목록에 없는 모델 ID를 입력해 고정해요"
}
],
"multiSelect": false
}]
}../config/SKILL.md. On the
user's local Codex App or Codex CLI this opens the settings UI in their
browser at a temporary localhost address; it is not an external website.
The UI offers Use Codex default model for the current Codex selection and
Enter another model ID… for a deliberate stage pin. After the settings
session ends, continue to Step 1.For Claude Code, ../setup/SKILL.md presents the equivalent model
choice during its own completion flow. Do not show this Codex-specific question
a second time; continue to Step 1 after the Claude setup skill returns.
Do not show this gate again once Codex is ready. The normal settings UI remains
available later through ooo config, so a model choice made now is never
permanent.

Ordinary Claude setup uses the default [claude] Agent SDK profile on MCP 1.x.
It intentionally leaves host-owned ~/.claude/mcp.json untouched; do not
inspect or mutate that file as an onboarding health check. The dependency-free

Merge the welcome completion fields into `~/.ouroboros/prefs.json` without deleting existing keys:
```bash

import json, os
from datetime import UTC, datetime
path = os.path.expanduser('~/.ouroboros/prefs.json')

MAGIC KEYWORDS (optional shortcuts):
Just include these naturally in your request:
| Keyword | Effect | Example |
|---------|--------|---------|
| interview | Socratic Q&A | "interview me about my app idea" |
| seed | Crystallize spec | "seed the requirements" |
| evaluate | 3-stage check | "evaluate this implementation" |
| stuck | Lateral thinking | "I'm stuck on the auth flow" |
REAL-TIME MONITORING (TUI):
When running ooo run or ooo evolve, open a separate terminal:
uvx --python '>=3.12' --from 'ouroboros-ai[tui]' ouroboros tui monitor
Press 1-4 to switch screens (Dashboard, Execution, Logs, Debug).
READY TO BUILD:
- ooo interview "your project idea"
- ooo tutorial # Interactive learning
- ooo help # Full reference~/.ouroboros/prefs.json:

"welcomeCompleted": "2025-02-23T15:30:00+09:00",

}Your final response MUST end with exactly one breadcrumb footer line:
◆ <current state> → next: <recommended action>Derive <current state> from live session state via ouroboros_session_status when that MCP projection is available; otherwise derive it from this skill's actual outcome. Never use a linear Step N of M footer because Ouroboros is an evolutionary loop. When the next action is genuinely a choice, list 2-3 honest options in the next: clause. The breadcrumb line must be the last line of the response.
