setup

/ouroboros:setup

Guided onboarding wizard that converts users into power users.

Standalone users (Codex, pip install): Use ouroboros setup --runtime codex in your terminal instead. This skill runs inside a Claude Code session. For other runtime backends, the CLI ouroboros setup command handles configuration. For full install and onboarding instructions, see Getting Started.

GitHub Copilot CLI users: Run ouroboros setup --runtime copilot (after pipx install 'ouroboros-ai[mcp]' or uv tool install 'ouroboros-ai[mcp]'). Setup will:

1. Live-discover available models from the GitHub Copilot models API (uses gh auth token) and let you pick a default. A bundled fallback list is used when offline.
2. Write orchestrator.runtime_backend = copilot and llm.backend = copilot plus your chosen default into ~/.ouroboros/config.yaml.
3. Register the MCP server in ~/.copilot/mcp-config.json so the next copilot session can call ooo ... skills.

Hyphen Anthropic IDs that the Ouroboros defaults use (for example claude-opus-4-6) are auto-mapped at runtime to the dotted form Copilot CLI expects (claude-opus-4.6), so existing config files keep working when you switch backends.

Usage

ooo setup
/ouroboros:setup
/ouroboros:setup --uninstall

Note: Setup does two things:

1. MCP server registration (~/.claude/mcp.json) — one-time, global across all projects
2. CLAUDE.md integration (optional) — per-project, adds an Ouroboros command reference block

After the first run, you only need to re-run setup in new projects if you want the CLAUDE.md integration.

Setup Wizard Flow

When the user invokes this skill, guide them through an enhanced 6-step wizard with progressive disclosure and celebration checkpoints.

---

Step 0: Welcome & Motivation (The Hook)

Start with energy and clear value:

Welcome to Ouroboros Setup!

Let's unlock your full AI development potential.

What you'll get:
- Visual TUI dashboard for real-time progress tracking
- 3-stage evaluation pipeline for quality assurance
- Drift detection to keep projects on track
- Cost optimization (85% savings on average)

Setup takes ~2 minutes. Let's go!

---

Step 0.5: Community Support

Before we begin, check ~/.ouroboros/prefs.json for star_asked. If not true, use AskUserQuestion:

{
  "questions": [{
    "question": "Ouroboros is free and open-source. A GitHub star helps other developers discover it. Star the repo?",
    "header": "Community",
    "options": [
      {
        "label": "Star on GitHub",
        "description": "Takes 1 second — helps the project grow"
      },
      {
        "label": "Skip for now",
        "description": "Continue with setup"
      }
    ],
    "multiSelect": false
  }]
}

• Star on GitHub: Run gh api -X PUT /user/starred/Q00/ouroboros, then merge {"star_asked": true} into ~/.ouroboros/prefs.json
• Skip for now: Merge {"star_asked": true} into ~/.ouroboros/prefs.json
• Other: Merge {"star_asked": true} into ~/.ouroboros/prefs.json

Create ~/.ouroboros/ directory if it doesn't exist. Preserve any existing keys such as welcomeShown, welcomeCompleted, and welcomeVersion when updating star_asked:

python3 - <<'PY'
import json, os
path = os.path.expanduser('~/.ouroboros/prefs.json')
os.makedirs(os.path.dirname(path), exist_ok=True)
try:
    with open(path, encoding='utf-8') as f:
        prefs = json.load(f)
    if not isinstance(prefs, dict):
        prefs = {}
except Exception:
    prefs = {}
prefs['star_asked'] = True
with open(path, 'w', encoding='utf-8') as f:
    json.dump(prefs, f, indent=2)
    f.write('\n')
PY

If star_asked is already true, skip this step silently.

---

Step 1: Environment Detection

Check the user's environment with clear feedback:

python3 --version
which uvx 2>/dev/null && uvx --version 2>/dev/null
which claude 2>/dev/null

IMPORTANT: If system Python is < 3.12 but uvx is available, also check uv-managed Python:

uv python list 2>/dev/null | grep "cpython-3.1[2-9]"

If uv python list shows Python >= 3.12 available, this counts as Full Mode because uvx ouroboros-ai mcp serve automatically uses uv-managed Python >= 3.12 (not system Python).

Report results with personality:

Environment Detected:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

System Python 3.11         [!] Below 3.12
uv Python 3.12+            [✓] Available (uvx will use this)
uvx package runner         [✓] Available
Runtime backend            [✓] Detected

→ Full Mode Available (via uvx + uv-managed Python >= 3.12)

Decision Matrix:

Environment	Mode	Action
uvx + Python >= 3.12	Ready	Proceed to MCP registration (uvx mode — extras always included)
No uvx + ouroboros binary in PATH	Check deps	Verify [claude] extras, then proceed (binary mode)
No uvx + Python >= 3.12 + python3 -m ouroboros works	Check deps	Verify [claude] extras, then proceed (pip mode)
uvx + Python < 3.12 only	Install needed	Run uv python install 3.12 then proceed
No uvx + no ouroboros binary + no pip package	Install needed	Install uv first, then proceed

For binary/pip modes — verify [claude] extras are installed:

Check method depends on how ouroboros was installed:

# Detect install method
pipx list 2>/dev/null | grep -q ouroboros && echo "PIPX" || echo "NOT_PIPX"

• pipx users (binary mode, installed via pipx):

  pipx runpip ouroboros-ai show claude-agent-sdk 2>/dev/null && echo "DEPS_OK" || echo "DEPS_MISSING"
  

  If DEPS_MISSING: pipx install --force ouroboros-ai[claude]

• pip users (pip mode):

  python3 -c "import claude_agent_sdk" 2>/dev/null && echo "DEPS_OK" || echo "DEPS_MISSING"
  

  If DEPS_MISSING: python3 -m pip install ouroboros-ai[claude]

If deps are missing and the user doesn't want to fix manually, recommend uv. Prefer package-manager paths over the vendor pipe-to-shell when the user's environment supports them (pipx > pip > brew > vendor one-liner):

Or install uv (recommended — handles deps automatically). Any one of:
  pipx install uv
  pip install --user uv
  brew install uv          # macOS / Linuxbrew
  curl -LsSf https://astral.sh/uv/install.sh | sh   # vendor one-liner (last resort)
Then re-run: ooo setup

IMPORTANT: The MCP server requires one of: (1) uvx, (2) ouroboros binary in PATH, or (3) ouroboros pip-installed. For options 2 and 3, the [claude] extra must also be installed. If none are available, guide the user to install uv — do NOT write a non-working fallback to mcp.json.

If prerequisites are missing, show:

Ouroboros requires uvx (recommended) or the ouroboros package installed.

Quick install (< 1 minute) — install uv via any of:
  pipx install uv
  pip install --user uv
  brew install uv          # macOS / Linuxbrew
  curl -LsSf https://astral.sh/uv/install.sh | sh   # vendor one-liner (last resort)
Then:
  uv python install 3.12

Then re-run: ooo setup

Celebration Checkpoint 1:

Great news! You're ready for the full Ouroboros experience.

---

Step 2: MCP Server Registration

Check if ~/.claude/mcp.json exists:

ls -la ~/.claude/mcp.json 2>/dev/null && echo "EXISTS" || echo "NOT_FOUND"

Show progress:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  Registering MCP Server...
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Connecting Ouroboros Python core to your runtime backend.
This enables:

  Visual TUI Dashboard    [Watch execution in real-time]
  3-Stage Evaluation     [Mechanical → Semantic → Consensus]
  Drift Detection        [Alert when projects go off-track]
  Session Replay         [Debug any execution from events]

Automatically create or update ~/.claude/mcp.json (user-level, works across all projects).

Choose the MCP command based on how ouroboros is installed (check in order):

1. If which uvx succeeds: {"command": "uvx", "args": ["--from", "ouroboros-ai[claude]", "ouroboros", "mcp", "serve"]}
2. If which ouroboros succeeds: {"command": "ouroboros", "args": ["mcp", "serve"]}
3. If python3 -c "import ouroboros" succeeds: {"command": "python3", "args": ["-m", "ouroboros", "mcp", "serve"]}
4. If none of the above → do NOT write to mcp.json. Instead show the prerequisites message from Step 1 and stop.

If ~/.claude/mcp.json already exists, read it, always overwrite the ouroboros key with the entry above (to fix stale args from older versions), and preserve all other server entries.

Celebration Checkpoint 2:

MCP Server Registered! You can now:
- Run ooo run for visual TUI execution
- Run ooo evaluate for 3-stage verification
- Run ooo status for drift tracking

---

Step 3: CLAUDE.md Integration (Optional)

Ask with clear value proposition:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  CLAUDE.md Integration
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Add Ouroboros quick-reference to your CLAUDE.md?

This gives you instant command reminders without leaving
your project context.

What gets added (~40 lines):
- Philosophy and pipeline overview
- Command routing table with lazy-loaded agents
- Agent catalog summary

A backup will be created: CLAUDE.md.bak

[Integrate / Skip / Preview first]

If "Preview first", show:

<!-- ooo:START -->
<!-- ooo:VERSION:0.39.1 -->
# Ouroboros — Specification-First AI Development

> Before telling AI what to build, define what should be built.
> As Socrates asked 2,500 years ago — "What do you truly know?"
> Ouroboros turns that question into an evolutionary AI workflow engine.

Most AI coding fails at the input, not the output. Ouroboros fixes this by
**exposing hidden assumptions before any code is written**.

1. **Socratic Clarity** — Question until ambiguity ≤ 0.2
2. **Ontological Precision** — Solve the root problem, not symptoms
3. **Evolutionary Loops** — Each evaluation cycle feeds back into better specs

```
Interview → Seed → Execute → Evaluate
    ↑                           ↓
    └─── Evolutionary Loop ─────┘
```

## ooo Commands

Each command loads its agent/MCP on-demand. Details in each skill file.

| Command | Loads |

<!-- ooo:END -->

If Integrate:

1. Backup existing CLAUDE.md to CLAUDE.md.bak
2. Append the block above
3. Confirm successful integration

Celebration Checkpoint 3:

CLAUDE.md updated! You now have instant Ouroboros reference
available in every project.

Step 5.5: Brownfield Repository Scan

Scan a root directory for existing git repositories and linked worktrees, then register them in the Ouroboros DB. This enables interviews to use brownfield context for existing projects.

Show scanning indicator:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  Scanning for Existing Projects...
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Looking for git repositories and worktrees under the scan root directory.
Linked worktrees reported by discovered normal repo roots may also be registered, even outside the scan root directory.
Local repos and repos with any remote name are eligible.
This may take a moment...

Implementation — use MCP tools only, do NOT use CLI or Python scripts:

1. Load the brownfield MCP tool: ToolSearch query: "+ouroboros brownfield"
2. Call scan+register:

   Tool: ouroboros_brownfield
   Arguments: { "action": "scan" }
   

   This walks scan_root for valid seed repos/worktrees and registers them in DB. For each discovered normal repo root with a .git directory, Git-reported linked worktrees are also considered, even when they live outside scan_root. A linked worktree found under scan_root with a .git file is registered itself, but it is not used to register its main worktree or sibling worktrees outside scan_root. Existing defaults are preserved.

Scan boundaries:

• The filesystem walk starts at scan_root; when omitted, scan_root defaults to the current user's home directory.
• Repositories are only discovered directly by walking directories inside scan_root.
• Dot-prefixed directories and known noisy directories such as node_modules are not walked as seed locations.
• Git worktrees are different: once a normal repo root with a .git directory is discovered, Ouroboros runs git worktree list --porcelain and may register those linked worktrees even if their paths are outside scan_root.
• A linked worktree found inside scan_root with a .git file is registered itself, but it is not used to register its main worktree or sibling worktrees outside scan_root.
• Local repos, repos without remotes, and repos whose remotes are not named origin are all eligible.

The scan response text already contains a pre-formatted numbered list with [default] markers. Do NOT make any additional MCP calls to list or query repos.

Display the repos in a plain-text 2-column grid (NOT a markdown table). Use a code block so columns align. Example:

Scan complete. 8 repositories registered.

 1. repo-alpha                   5. repo-epsilon
 2. repo-bravo *                 6. repo-foxtrot
 3. repo-charlie                 7. repo-golf *
 4. repo-delta                   8. repo-hotel

Include * markers for defaults exactly as they appear in the scan response. Do not summarize or truncate the list. The user needs to see all repo numbers to pick defaults.

If no repos found, skip the default selection prompt and proceed to Step 6.

Default repo selection — IMMEDIATELY after showing the list:

Use AskUserQuestion with the current default numbers from the scan response.

If defaults exist, show them as the recommended option:

{
  "questions": [{
    "question": "Which repos to set as default for interviews? Enter numbers like '6, 18, 19'.",
    "header": "Default Repos",
    "options": [
      {"label": "<current default numbers> (Recommended)", "description": "<current default names>"},
      {"label": "None", "description": "Clear all defaults — interviews will run in greenfield mode"},
      {"label": "Select repos", "description": "Type repo numbers to set as default"}
    ],
    "multiSelect": false
  }]
}

If no defaults exist, do NOT show a "(Recommended)" option — offer "None" and "Select repos" instead:

{
  "questions": [{
    "question": "Which repos to set as default for interviews? Enter numbers like '6, 18, 19'.",
    "header": "Default Repos",
    "options": [
      {"label": "None", "description": "No default repos — interviews will run in greenfield mode"},
      {"label": "Select repos", "description": "Type repo numbers to set as default"}
    ],
    "multiSelect": false
  }]
}

The user can select the recommended defaults (if any), choose "None", or type custom numbers.

After the user responds, use ONE MCP call to update all defaults at once:

Tool: ouroboros_brownfield
Arguments: { "action": "set_defaults", "indices": "<comma-separated IDs>" }

Example: if the user picks IDs 6, 18, 19 → { "action": "set_defaults", "indices": "6,18,19" }

This clears all existing defaults and sets the selected repos as default in one call.

If "none" → { "action": "set_defaults", "indices": "" } to clear all defaults.

Celebration Checkpoint 5.5:

Brownfield defaults updated!
Defaults: podo-app, podo-backend, grape

These repos will be used as context in interviews.

Or if "none" selected:

No default repos set. interviews will run in greenfield mode.
You can set defaults anytime by running ooo setup again.

Step 6: First Project Nudge

Encourage immediate action:

Your first Ouroboros project is waiting!

The best way to learn is by doing. Try:

  ooo interview "Build a CLI tool for [something you need]"

Or explore examples:
  ooo tutorial

You're going to love seeing vague ideas turn into
crystal-clear specifications. Let's build something amazing!

---

Uninstall

When invoked with --uninstall:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  Ouroboros Uninstall
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

This will remove:
- MCP server registration from ~/.claude/mcp.json
- Ouroboros block from CLAUDE.md

This will NOT remove:
- Plugin files in .claude-plugin/
- Any generated seeds or projects
- Your project data

Uninstall Ouroboros configuration? [Yes / No]

If Yes:

1. Remove ouroboros entry from ~/.claude/mcp.json (if exists)
2. Remove <!-- ooo:START --> to <!-- ooo:END --> block from CLAUDE.md (if exists)
3. Confirm: "Ouroboros plugin configuration removed. To remove plugin files, run: claude plugin uninstall ouroboros"

---

Setup Troubleshooting

"python3: command not found"

Plugin mode still works! You can use:
- ooo interview
- ooo seed
- ooo unstuck

For Full Mode, install Python >= 3.12:
  macOS: brew install python@3.12
  Ubuntu: sudo apt install python3.12
  Windows: python.org/downloads

"uvx: command not found"

uvx is recommended but not required. Alternative:

Install Ouroboros globally (see docs/getting-started.md for all options):
  pip install ouroboros-ai

Then update ~/.claude/mcp.json with:
  "command": "python"
  "args": ["-m", "ouroboros", "mcp", "serve"]

"~/.claude/mcp.json conflicts"

Ouroboros will merge with existing MCP servers.
If you see issues, share your ~/.claude/mcp.json content and
we'll help you resolve conflicts.
