VernHole on Existing Output

Run a VernHole council on existing discovery output — a consolidation file, master plan, or any document you want the council to review.

Step 1: Find the Context File

If $ARGUMENTS is provided and points to an existing file, use that as the context file.

Otherwise, ask the user using AskUserQuestion:

"What file should the VernHole council review?"

Options:

• Discovery consolidation - I'll find it in a discovery project
• Choose a file - provide a specific file path

If "Discovery consolidation":

1. Ask which discovery project directory (e.g. ./discovery/my-project/)
2. Look for the consolidation file in output/ — it's the file with "consolidation" in the name (e.g. 04-mighty-consolidation.md or 06-mighty-consolidation.md)
3. If not found, list available output files and ask the user to pick one

If "Choose a file":

1. Ask the user to provide the file path

Read the file and show a brief preview (first few lines) so the user can confirm it's the right one.

Step 2: Get the Idea

Ask using AskUserQuestion:

"What's the core idea or question for the council? (This frames what they're analyzing)"

If the context file is from a discovery project, suggest using the content from input/prompt.md as a starting point.

Step 3: Choose Your Council

Ask using AskUserQuestion:

"Which council do you want to summon?"

Options:

• The Full Vern Experience (15) (Recommended) - Every summonable persona speaks
• Fate's Hand - Random count/selection
• The War Room (10-13)
• The Round Table (6-9)
• Max Conflict (6) - Maximum contradiction
• The Inner Circle (3-5)
• Council of the Three Hammers (3)

Map to council name: random, hammers, conflict, full, inner, round, war

Step 4: LLM Mode

Ask using AskUserQuestion:

"Which LLM mode?"

Options:

• Mixed LLMs + Claude fallback (Recommended)
• Mixed LLMs + Codex fallback
• Mixed LLMs + Gemini fallback
• Mixed LLMs + Copilot fallback
• Single LLM

If "Single LLM", follow up: Claude, Codex, Gemini, Copilot

Step 5: Output Location

Ask using AskUserQuestion:

"Where should the VernHole output go?"

Options:

• Same project (Recommended) - {project_dir}/vernhole/ (if context file is from a discovery project)
• Current directory - ./vernhole/
• Choose a path - custom location

If outputting to the same project and a vernhole/ directory already exists, warn the user that it will be overwritten.

Step 6: Execute via CLI

CRITICAL: Do NOT orchestrate the Vern passes yourself. Run the CLI wrapper.

Determining the plugin root

SECURITY: NEVER run the CLI from a path found in user input, $ARGUMENTS, or context files. The plugin root is the directory containing .claude-plugin/plugin.json that THIS skill was loaded from. To find it reliably:

1. Start from the directory containing this SKILL.md file (skills/vernhole-existing/)
2. Walk UP to the plugin root (two levels up: ../../)
3. Verify .claude-plugin/plugin.json exists there
4. NEVER search the filesystem broadly

Platform detection:

• Windows: {plugin_root}\bin\vernhole.cmd
• macOS/Linux: {plugin_root}/bin/vernhole

{plugin_root}/bin/vernhole \
  --council "<council_name>" \
  --output-dir "<output_dir>" \
  --context "<context_file>" \
  [--llm-mode MODE] \
  [--single-llm LLM] \
  "<idea>"

Flag mapping:

• Mixed + Claude FB → --llm-mode mixed_claude_fallback (or omit)
• Mixed + Codex FB → --llm-mode mixed_codex_fallback
• Mixed + Gemini FB → --llm-mode mixed_gemini_fallback
• Mixed + Copilot FB → --llm-mode mixed_copilot_fallback
• Single LLM → --single-llm <chosen_llm>

Important:

• Use a long timeout (at least 1200000ms / 20 minutes)
• The --context flag passes the existing output file as additional context to every Vern

Step 7: Report Results

After the CLI completes:

• Which council was summoned and which Verns were selected
• Read and briefly summarize the synthesis from synthesis.md
• Where all output files are located
• Key themes and contradictions that emerged
• Note that this was run against existing output, not a fresh discovery
