Delphi

• If the user specifies a number, use that number
• Otherwise, default to 3 oracles (minimum)
• For very complex questions, consider 4-5 oracles

Step 2: Formulate the Oracle Prompt

Create a single prompt that will be sent to ALL oracles identically. The prompt should:

1. Core Question - The specific question needing investigation
2. Context - All relevant information from the user
3. Success Criteria - What a good answer looks like
4. Export Instructions - Tell the oracle to export its full thinking

Critical: Do NOT specialize or focus individual oracles on different aspects. The power of Delphi comes from identical starting points leading to organically divergent exploration.

Step 3: Launch Oracles in Parallel

First, create the output directory:

mkdir -p .oracle/[topic]

Then dispatch ALL oracles simultaneously in a single message with multiple Task calls:

Task(
  subagent_type: "general-purpose",
  model: "opus",
  prompt: <identical oracle prompt for oracle #1>
)

Task(
  subagent_type: "general-purpose",
  model: "opus",
  prompt: <identical oracle prompt for oracle #2>
)

Task(
  subagent_type: "general-purpose",
  model: "opus",
  prompt: <identical oracle prompt for oracle #3>
)
// ... etc

Step 4: Oracle Prompt Template

Use this template for each oracle:

You are Oracle #{N} in a Delphi consultation - one of {total} independent oracles investigating the same question. Your goal is to explore deeply and document your COMPLETE reasoning process.

## Your Mission

CORE QUESTION:
{the specific question}

CONTEXT:
{all relevant context}

SUCCESS CRITERIA:
{what a good answer looks like}

## Your Process

### Phase 1: Plan Your Research
Think about what needs investigation:
- What paths should be explored?
- What code/documentation might be relevant?
- What patterns should be searched?

### Phase 2: Deep Investigation
Use extended thinking to thoroughly investigate. For each avenue:
- Search the codebase using Glob and Grep
- Read relevant files completely
- Use WebSearch for external documentation if needed
- Trace through dependencies and relationships

DO NOT STOP at the first answer. Follow every interesting thread.

### Phase 3: Document Your Exploration
As you work, keep track of:
- Hypotheses you formed and tested
- Dead ends you encountered (and why they were dead ends)
- Surprising discoveries
- Connections between different findings

### Phase 4: Export Your Full Thinking

When complete, write your ENTIRE elaborated thinking to:
`.oracle/{topic}/delphi-{topic}-{N}.md`

The export MUST include:
1. **Initial Hypotheses** - What you thought at the start
2. **Research Path** - Every avenue explored, in order
3. **Dead Ends** - Paths that didn't pan out and why
4. **Key Discoveries** - Important findings with evidence
5. **Synthesis** - Your answer to the core question
6. **Confidence & Caveats** - What you're sure about vs uncertain
7. **Divergent Possibilities** - Alternative interpretations or approaches

Be verbose. The synthesis phase needs your full reasoning chain.

## Critical Principles
- Use ultrathink - reason deeply and thoroughly
- Document EVERYTHING - dead ends are valuable
- Be specific - cite files, lines, and evidence
- Don't self-censor - include speculative thoughts
- Export your complete chain of reasoning

Step 5: Synthesize Results

After all oracles complete, dispatch a synthesis oracle:

Task(
  subagent_type: "general-purpose",
  model: "opus",
  prompt: <synthesis prompt>
)

Synthesis Prompt Template:

You are the Synthesis Oracle for a Delphi consultation. Multiple oracles independently investigated the same question. Your job is to synthesize their findings into a unified analysis.

## Your Mission

Read all oracle reports in `.oracle/{topic}/delphi-{topic}-*.md` and create a synthesis.

## Synthesis Process

### Phase 1: Read All Reports
Read each oracle's full report completely. Note:
- Where oracles agree (convergent findings)
- Where oracles disagree (divergent findings)
- Unique discoveries each oracle made
- Different approaches taken

### Phase 2: Analyze Patterns

**Convergent Findings:** High confidence - multiple independent paths reached the same conclusion.

**Divergent Findings:** Investigate why:
- Different assumptions?
- Different evidence found?
- Different interpretations of same evidence?
- Complementary perspectives on complex issue?

**Unique Findings:** Single oracle discoveries that others missed. Evaluate validity.

### Phase 3: Create Synthesis

Write to `.oracle/{topic}/{topic}-synthesis.md`:

# Delphi Synthesis: {topic}

## Executive Summary
[2-3 paragraph summary of the key findings]

## Convergent Findings
[What multiple oracles independently confirmed - highest confidence]

## Divergent Findings
[Where oracles disagreed, with analysis of why]

## Unique Discoveries
[Important findings from individual oracles]

## Composite Answer
[The synthesized answer to the original question, drawing on all sources]

## Confidence Assessment
[What we're confident about vs uncertain about]

## Recommended Actions
[Concrete next steps based on the synthesis]

## Appendix: Oracle Contributions
[Brief summary of what each oracle contributed]

Step 6: Present Results

After synthesis completes:

1. Read the synthesis document
2. Present the key findings to the user
3. Offer to dive deeper into any specific oracle's findings

Example Invocation

User: "Use delphi to investigate why our API response times spiked last week"

1. Create .oracle/api-latency/
2. Launch 3 oracles in parallel with identical prompts about API latency investigation
3. Each oracle independently explores: logs, code changes, dependencies, infrastructure
4. Each exports to delphi-api-latency-1.md, delphi-api-latency-2.md, delphi-api-latency-3.md
5. Synthesis oracle reads all three and creates api-latency-synthesis.md
6. Present findings to user

Key Principle

Same prompt, divergent exploration. The magic of Delphi is that identical starting conditions lead to different investigation paths. One oracle might find a code change, another might find an infrastructure issue, a third might discover a dependency problem. Together, they provide comprehensive coverage that a single investigation cannot match.
