/ouroboros:brownfield

Scan your home directory for existing git repositories and manage default repos used as context in interviews.

Usage

ooo brownfield                # Scan repos and set defaults
ooo brownfield scan           # Scan only (no default selection)
ooo brownfield defaults       # Show current defaults
ooo brownfield set 6,18,19   # Set defaults by repo numbers

Trigger keywords: "brownfield", "scan repos", "default repos", "brownfield scan"

How It Works

Default flow (ooo brownfield with no args)

Step 1: Scan

Show scanning indicator:

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

Looking for git repositories in your home directory.
Only GitHub-hosted repos will be registered.
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:
   Copy

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

   This scans ~/ for GitHub repos and registers them in DB. Existing defaults are preserved.

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.

If no repos found, show:

No GitHub repositories found in your home directory.

Then stop.

Step 2: Default 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": "No default repos — interviews will run in greenfield mode"}
    ],
    "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.

Step 3: Confirmation

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

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 with: ooo brownfield

Subcommand: scan

Scan only, no default selection prompt. Show the numbered list and stop.

Subcommand: defaults

Load the brownfield MCP tool and call:

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

Display only the repos marked with * (defaults). If none, show:

No default repos set. Run 'ooo brownfield' to configure.

Subcommand: set <indices>

Directly set defaults without scanning. Parse the comma-separated indices from the user's input and call:

Tool: ouroboros_brownfield
Arguments: { "action": "set_defaults", "indices": "<indices>" }

Show confirmation with updated defaults.
