Deep Research

Research complex topics thoroughly with verified sources and structured findings.

Installation

  1. Make sure Claude is on your device and in your terminal.

    Skills load from ~/.claude/skills/ when Claude Code starts up — so you need it on your machine first. If you don't have it yet, install it once with the command below, then run claude in any terminal to verify.

    One-time setup
    npm i -g @anthropic-ai/claude-code

    Already have it? Skip ahead.

  2. Paste into Claude Code or into your terminal.

    This copies the whole skill folder into ~/.claude/skills/deep-research-shobcoder/ — the SKILL.md plus any scripts, reference docs, or templates the skill ships with. Safe default: works for every skill.

    Faster alternative (instruction-only skills)

    Skips the clone and grabs only the SKILL.md file. Don't use this if the skill ships Python scripts, reference markdowns, or asset templates — they won't be downloaded and the skill will fail when it tries to load them.

    Quick install (SKILL.md only)
    Sign up to copy
  3. Restart Claude Code.

    Quit and reopen Claude Code (or any other agent that loads from ~/.claude/skills/). New skills are picked up on startup.

  4. Just ask Claude.

    Skills auto-activate when your request matches the skill's description — no slash command needed. Trigger phrases live in the skill's own frontmatter; you can read them in the “What this skill does” section above.

Prefer to read the source first? Open on GitHub.

When Claude uses it

GOD MODE deep research skill. Multi-phase autonomous research loop: query decomposition → multi-source crawling → claim cross-referencing → conflict resolution → structured synthesis with inline citations. Use for any question that demands depth, sourcing, and verifiable accuracy.

What this skill does

Deep Research — GOD MODE

Trigger

/deep-research <query> or when user says "research this deeply", "go deep on", "full research report on", "investigate this thoroughly".

Core Philosophy

Raw search results are noise. Verified synthesis is signal. Every claim needs a source. Every conflict needs a resolution. A great deep research report is a structured intelligence brief, not a search summary.

Architecture

Query
  └── Phase 1: Decompose → Sub-questions
        └── Phase 2: Parallel Search → Raw Sources
              └── Phase 3: Crawl & Extract → Claims
                    └── Phase 4: Cross-Reference → Verify / Conflict
                          └── Phase 5: Synthesize → Report
                                └── Phase 6: Quality Gates → Deliver

Phase 1 — Query Decomposition

Break the user's query into 3–7 atomic sub-questions. Each must be:

  • Independently searchable
  • Non-overlapping with others
  • Ordered from foundational to advanced

Example:

Query: "Is Company X profitable?"

Sub-questions:

  1. What is Company X's current revenue model?
  2. What are its reported ARR and revenue figures?
  3. What is its burn rate and cost structure?
  4. What do investors say about its path to profitability?
  5. How does it compare to competitors on unit economics?

Phase 2 — Multi-Source Search Strategy

For each sub-question, issue 2–4 targeted searches using varied query angles:

[primary term] [year]
[primary term] site:official OR filetype:pdf
[primary term] analysis OR breakdown OR report
[primary term] vs [competitor]

Source Priority Tiers:

TierTypeTrust Weight
1Official docs, SEC filings, company blogs, government data, peer-reviewed papers1.0
2Major news outlets (Reuters, Bloomberg, FT), industry analysts (Gartner, CB Insights)0.85
3Tech blogs, newsletters, podcasts0.65
4Forums, Reddit, social media0.40

Minimum sources per report: 8 unique domains Target for complex topics: 15–25 sources


Phase 3 — Deep Crawl and Extraction

For each source, fetch the full page (not just the snippet), then extract structured claims:

  • Numerical facts (stats, dates, prices, percentages)
  • Named entities (people, companies, products)
  • Causal claims ("X caused Y because Z")
  • Comparative claims ("A is better than B")

Tag each claim with source URL, publish date, tier rating, and a paraphrase or verbatim quote under 15 words.

Extraction template per source:

source: https://example.com/article
published: 2026-04-12
tier: 2
claims:
  - text: "Company reached $100M ARR in Q1 2026"
    type: numerical
    confidence: high
  - text: "CEO stated profitability target by 2027"
    type: causal
    confidence: medium

Phase 4 — Cross-Reference and Conflict Resolution

4a. Claim Clustering

Group identical or related claims across sources. If 3+ Tier 1–2 sources agree, mark as Verified.

4b. Conflict Detection

Flag claims where sources contradict each other:

CONFLICT DETECTED
  Claim A: "Revenue is $50M ARR" — Source A, 2026-01
  Claim B: "Revenue is $80M ARR" — Source B, 2026-03
  Resolution: Use most recent Tier 1–2 source. Note discrepancy in report.

4c. Gap Detection

If a sub-question has zero Tier 1–2 sources, mark it [unverified] and flag it in the report.

4d. Confidence Scoring

Confidence = (sum of tier_weights x recency_factor) / num_claims

recency_factor:
  < 30 days:   1.0
  30–90 days:  0.9
  3–12 months: 0.75
  > 1 year:    0.60

Phase 5 — Report Synthesis

Phase 6 — Quality Gates

Run all checks before delivering the report. Fail = do not deliver until resolved.

GateRequirementAction if Fail
Source minimum8+ unique domainsRun additional search passes
Tier coverage40%+ Tier 1–2 sourcesFlag low-quality sourcing in report
Conflict resolutionAll conflicts documentedAdd to conflicts table
Gap flaggingAll unanswered sub-questions notedAdd to gaps section
Citation accuracyEvery claim has a sourceRemove or flag orphan claims
Recency50%+ sources within 12 monthsFlag stale data in report

Output Modes

Use a flag in the trigger to switch modes:

FlagModeDescription
(none)StandardFull report as specified above
[academic]AcademicAdds abstract, methodology, limitations, further research
[brief]Quick BriefExecutive summary + top 5 facts + source list. Max 300 words
[compare]ComparisonSide-by-side table of N items across shared dimensions

Iteration Protocol

If confidence is below 70% after the first pass:

ITERATION 2:
  - Re-run searches with refined queries
  - Target gaps identified in Phase 4
  - Fetch Tier 1 sources directly (company.com, arxiv.org, gov sites)
  - Update confidence scores
  - Note in report: "This section required 2 research iterations"

Maximum iterations: 3
If confidence remains below 60% after 3 iterations, deliver with prominent uncertainty warnings.

Anti-Hallucination Rules

  1. Never invent a statistic. If a number is not sourced, write [no data found].
  2. Never paraphrase into a stronger claim. If a source says "may reach", do not write "will reach".
  3. Never merge two sources' claims into one sentence without attributing both.
  4. Never omit a conflict because it is inconvenient — surface it in the conflicts table.
  5. Date every claim. Undated claims receive a recency penalty in confidence scoring.
  6. If uncertain, say so explicitly using [unverified] or [disputed] inline tags.
  7. Never reproduce more than 15 words verbatim from any single source.
