[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting.

Prerequisites: MUST READ before executing:

• .claude/skills/shared/web-research-protocol.md

External Memory: For complex or lengthy work (research, analysis, scan, review), write intermediate findings and final results to a report file in plans/reports/ — prevents context loss and serves as deliverable.

Evidence Gate: MANDATORY IMPORTANT MUST — every claim, finding, and recommendation requires file:line proof or traced evidence with confidence percentage (>80% to act, <80% must verify first).

Quick Summary

Goal: Deep-dive into top sources, extract key findings, cross-validate claims, build structured evidence base.

Workflow:

1. Read source map — Load output from web-research step
2. Fetch top sources — WebFetch top 5-8 Tier 1-2 sources
3. Extract findings — Pull key facts, data points, quotes
4. Cross-validate — Compare findings across sources
5. Build evidence base — Structured findings with confidence scores

Key Rules:

• Maximum 8 WebFetch calls per invocation
• Every finding must cite specific source
• Conflicting claims → present both, flag discrepancy

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

Deep Research

Step 1: Load Source Map

Read the source map from .claude/tmp/_sources-{slug}.md (output of web-research step).

Prioritize sources for deep-dive:

1. Tier 1-2 sources first
2. High-relevance sources
3. Sources covering identified gaps

Step 2: Fetch Top Sources

For each priority source (max 8):

1. Run WebFetch with the URL
2. Extract: key claims, data points, quotes, methodology
3. Note: publication date, author credentials, source type

Step 3: Extract Findings

For each source, extract:

• Key claims — factual statements with specific data
• Data points — numbers, percentages, dates
• Quotes — notable expert statements
• Methodology — how data was gathered (for market reports)

Step 4: Cross-Validate

Compare findings across sources:

• Agreement — 2+ sources say the same thing → high confidence
• Discrepancy — sources disagree → note both positions
• Unique — only 1 source → mark as "single source, unverified"

Step 5: Build Evidence Base

Write to .claude/tmp/_evidence-{slug}.md:

# Evidence Base: {Topic}

**Date:** {date}
**Sources analyzed:** {count}

## Findings

### Finding 1: {Title}

**Confidence:** {95%|80%|60%|<60%}
**Sources:** [1], [3]
**Content:** {finding with inline citations}
**Cross-validation:** {agreement/discrepancy notes}

## Unresolved Discrepancies

- {claim X from source A vs claim Y from source B}

## Gaps Remaining

- {what couldn't be verified}

Workflow Recommendation

IMPORTANT MUST: If you are NOT already in a workflow, use AskUserQuestion to ask the user:

1. Activate research workflow (Recommended) — web-research → deep-research → synthesis → review
2. Execute /deep-research directly — run this skill standalone

Next Steps

MANDATORY IMPORTANT MUST after completing this skill, use AskUserQuestion to recommend:

• "/business-evaluation (Recommended)" — Evaluate business viability from research
• "/knowledge-synthesis" — If synthesizing research report
• "Skip, continue manually" — user decides

Closing Reminders

MANDATORY IMPORTANT MUST break work into small todo tasks using TaskCreate BEFORE starting. MANDATORY IMPORTANT MUST validate decisions with user via AskUserQuestion — never auto-decide. MANDATORY IMPORTANT MUST add a final review todo task to verify work quality.
