Gemini Research

Gemini Research Pipeline v2

Overview

An iterative multi-agent research pipeline. Claude decomposes a topic, fans out parallel Gemini + Exa agents (Wave 1), performs gap analysis to find what's missing or contradictory, runs targeted follow-up agents (Wave 2), verifies key claims across independent sources, then synthesizes a confidence-rated report saved to Obsidian.

Pipeline at a Glance

Step 0: Gather user intent
Step 1: Topic decomposition
Step 2: Wave 1 — Broad parallel research
Step 3: Gap analysis — Find holes, contradictions, thin areas
Step 4: Wave 2 — Targeted follow-up research
Step 5: Source verification — Cross-check key claims
Step 6: Synthesis — Merge, rate confidence, build structure
Step 7: Save to Obsidian — Rich formatting with callouts and badges

Depth controls which stages run:

Step 0: Gather User Intent (Required)

Before ANY research begins, use AskUserQuestion to establish preferences. Ask all three in a single AskUserQuestion call with multiple questions:

Q1: "What should I title this research report?"
    Header: "Title"
    Options: [auto-generated suggestion, "Let me name it"]

Q2: "Where should I save it in Obsidian?"
    Header: "Location"
    Options: ["Research/ folder (default)", "Specify a different path"]

Q3: "How deep should the research go?"
    Header: "Depth"
    Options: [
      "Quick — Fast overview, single research wave",
      "Standard — Solid coverage with source verification (Recommended)",
      "Deep — Full iterative pipeline with gap analysis and follow-up waves"
    ]

Only proceed after all are answered.

Step 1: Topic Decomposition

Claude breaks the research topic into focused, non-overlapping subtopics. Each subtopic must be:

• Specific: searchable as a standalone query
• Distinct: minimal overlap with other subtopics
• Angled: approaches the main topic from a unique perspective

Subtopic count by depth:

Also identify:

• What structured data Exa should search for (companies, news, people, papers)
• What time range matters (last week, month, year, all time)
• Any specific domains to prioritize or exclude

Present the decomposition to the user before proceeding:

"I've broken this into N subtopics: [list]. Starting research now."

Step 2: Wave 1 — Broad Parallel Research

Launch all agents in a single message with multiple Task tool calls for true parallelism.

Gemini Agents (one per subtopic)

Each Task agent (model: haiku for speed):

1. Formulates a focused research prompt for its subtopic
2. Pipes to Gemini CLI:

   export GEMINI_API_KEY="..." && gemini <<'PROMPT'
   You are a research analyst. Research the following topic using web grounding.
   
   TOPIC: [subtopic]
   CONTEXT: This is part of a broader investigation into [main topic].
   
   Requirements:
   1. Provide 8-12 key findings as bullet points
   2. For EVERY finding, include the source URL in parentheses
   3. Include direct quotes where they add value (with attribution)
   4. Note any data points, statistics, or metrics with their dates
   5. Flag anything that seems contradictory to common understanding
   6. Note the recency of your sources (date published if available)
   
   Format your response as:
   
   ## Findings
   - [finding] (source: URL)
   ...
   
   ## Key Data Points
   - [metric/stat]: [value] — [source, date]
   ...
   
   ## Contradictions or Surprises
   - [anything unexpected or conflicting]
   ...
   
   ## Source List
   1. [Title](URL) — [date if known] — [brief relevance note]
   ...
   PROMPT
   

3. Parses the response into structured JSON
4. Returns:

   {
     "subtopic": "...",
     "findings": [
       {"claim": "...", "source_url": "...", "source_title": "...", "date": "...", "has_quote": false}
     ],
     "data_points": [
       {"metric": "...", "value": "...", "source": "...", "date": "..."}
     ],
     "contradictions": ["..."],
     "sources": [{"title": "...", "url": "...", "date": "...", "relevance": "..."}]
   }
   

Critical: Every finding MUST have a source URL. Unsourced findings are discarded.

Exa Agents (parallel with Gemini)

Launch separate Exa Task agents per category for better coverage:

Exa News Agent (if news is relevant):

• Category: news
• 2-3 query variations
• startPublishedDate set to relevant time window
• Return: headlines, URLs, publication dates, summaries

Exa Company Agent (if companies are relevant):

• Category: company
• Returns rich metadata: headcount, funding, revenue, location
• Include enableSummary: true for context

Exa People Agent (if people/profiles matter):

• Category: people
• Public LinkedIn and profile data

Exa Research Agent (if academic/technical):

• Category: research paper
• Include enableHighlights: true with highlightsQuery set to main topic

Each Exa agent uses mcp__exa__web_search_advanced_exa with:

• numResults: 15-25 depending on depth
• enableSummary: true
• contextMaxCharacters: 5000
• 2-3 query variations merged and deduplicated

Step 3: Gap Analysis (Standard + Deep only)

After all Wave 1 agents return, Claude reviews the collected findings and identifies:

3a. Coverage Gaps

• Subtopics where agents returned fewer than 3 findings
• Angles on the main topic that no subtopic addressed
• Time periods with no coverage

3b. Contradictions

• Findings from different agents that directly conflict
• Data points that disagree (e.g., different funding amounts)
• Claims that contradict well-known facts

3c. Unsubstantiated Claims

• Findings with only one source
• Claims that are significant but lack supporting data
• Surprising assertions that need independent confirmation

3d. Depth Gaps

• Areas where findings are surface-level (e.g., "X is growing" without numbers)
• Topics that deserve deeper exploration based on initial findings

Generate a structured gap report:

{
  "coverage_gaps": ["...", "..."],
  "contradictions": [
    {"claim_a": "...", "source_a": "...", "claim_b": "...", "source_b": "..."}
  ],
  "needs_verification": ["claim 1", "claim 2"],
  "needs_depth": ["area 1", "area 2"],
  "follow_up_queries": ["specific query 1", "specific query 2"]
}

For Standard depth: Skip to Step 5 (verification) using this gap analysis to prioritize what to verify. For Deep depth: Continue to Step 4 (Wave 2).

Step 4: Wave 2 — Targeted Follow-Up (Deep only)

Launch targeted agents based on the gap analysis. These are different from Wave 1 — they address specific holes, not broad subtopics.

Gap-Filling Agents

For each coverage gap, launch a Gemini agent with a highly specific prompt:

export GEMINI_API_KEY="..." && gemini <<'PROMPT'
I'm researching [main topic] and found a gap in coverage around [specific gap].

Previous research established: [brief context from Wave 1]

Please research specifically:
- [targeted question 1]
- [targeted question 2]

Include source URLs for every finding.
PROMPT

Contradiction-Resolution Agents

For each contradiction, launch an agent specifically to resolve it:

export GEMINI_API_KEY="..." && gemini <<'PROMPT'
I found conflicting information while researching [topic]:

Claim A: "[claim]" (source: [url])
Claim B: "[claim]" (source: [url])

Please determine:
1. Which claim is more accurate and why
2. Are both partially correct with different contexts?
3. What do the most authoritative sources say?

Include source URLs for your determination.
PROMPT

Depth Agents

For areas needing more depth, launch agents with prompts that reference what Wave 1 found:

export GEMINI_API_KEY="..." && gemini <<'PROMPT'
Previous research found that [surface-level finding].

Go deeper:
- What are the specific numbers/metrics?
- What's the timeline of developments?
- Who are the key players involved?
- What are the second-order effects?

Include source URLs.
PROMPT

All Wave 2 agents launch in parallel in a single message.

Step 5: Source Verification (Standard + Deep)

For key claims (the most important 8-12 findings from the research), run a verification pass.

Launch verification agents in parallel. Each agent takes one claim and checks it:

export GEMINI_API_KEY="..." && gemini <<'PROMPT'
VERIFICATION TASK

Claim to verify: "[claim]"
Original source: [url]

Please:
1. Search for this claim or closely related information
2. Find 2-3 independent sources that either confirm or contradict it
3. Rate your confidence: HIGH (3+ independent sources agree), MEDIUM (2 sources agree), LOW (only original source or contradicted)

Return:
- Confidence: HIGH/MEDIUM/LOW
- Supporting sources: [list with URLs]
- Contradicting sources: [list with URLs, if any]
- Notes: [any nuance or caveats]
PROMPT

Map verification results back to findings:

Step 6: Synthesis

Claude (opus for Deep, sonnet for Standard/Quick) synthesizes all findings across all waves.

6a. Thematic Grouping

Organize findings by theme, not by subtopic or wave:

• Group related findings from different agents together
• Identify overarching narratives across themes

6b. Confidence Rating

Attach confidence badges from Step 5 to each finding. For Quick depth (no verification), default to [🔶 likely] for multi-source and [⚠️ unverified] for single-source.

6c. Comparative Tables

Where data supports it, build comparison tables:

| Company | Funding | Headcount | Last Round |
|---------|---------|-----------|------------|
| Acme    | $50M    | 200       | Series B   |
| Beta    | $30M    | 150       | Series A   |

6d. Timeline Construction

If findings have temporal data, construct a timeline:

> [!timeline]
> **2024 Q1** — Event A happened
> **2024 Q3** — Event B followed
> **2025 Q1** — Current state

6e. Contradictions Report

List any unresolved contradictions with both sides presented:

> [!warning] Disputed Finding
> Source A claims X ([url]), while Source B claims Y ([url]).
> **Assessment**: [Claude's analysis of which is more credible and why]

Step 7: Save to Obsidian

Use Obsidian MCP tools to write the report with rich formatting.

Gemini CLI Invocation (Critical)

Always pipe prompts non-interactively:

export GEMINI_API_KEY="..." && gemini <<'PROMPT'
[prompt content]
PROMPT

NEVER use interactive mode. Always pipe input via heredoc.

The GEMINI_API_KEY must be exported in the same command since Task agents don't inherit env vars.

Error Handling

• gemini not found: Tell user to run setup.sh or npm install -g @google/gemini-cli
• Auth failure: Tell user to set GEMINI_API_KEY or run gemini interactively once
• Agent returns empty: Retry once with simplified prompt. If still empty, log as coverage gap.
• Obsidian MCP unavailable: Fall back to writing the report as a local markdown file.
• Partial agent failure: Synthesize from successful agents. Note failed subtopics in Research Metadata.
• Wave 2 failure: Still produce report from Wave 1 data. Note in metadata that follow-up was incomplete.
• Verification timeout: Mark unverified findings as [⚠️ unverified] rather than blocking the report.

Models

• haiku: Wave 1 + Wave 2 fan-out agents, verification agents (speed — Gemini does the heavy lifting)
• sonnet: Exa agents, gap analysis, Quick/Standard synthesis
• opus: Deep synthesis (6+ agent results, cross-wave merging, contradiction analysis)
