Produces comprehensive, well-sourced research reports through iterative refinement using Time-Tested Diffusion methodology. Triggers on "deep research", "thorough analysis", "comprehensive report", "investigate", "due diligence", or when multiple sources are needed to answer complex questions.
This skill inherits all available tools. When active, it can use any tool Claude has access to.
references/critique-framework.mdreferences/report-templates.mdreferences/search-patterns.mdreferences/source-evaluation.mdIterative methodology treating research as a diffusion process: start with noise (rough draft), apply guidance (research brief), denoise through cycles of critique → research → refine until quality converges.
Progress:
- [ ] 1. Clarify scope (if ambiguous)
- [ ] 2. Write research brief (guidance signal)
- [ ] 3. Generate initial draft from knowledge (noisy starting point)
- [ ] 4. Red team critique (identify noise)
- [ ] 5. Targeted web_search with reflection
- [ ] 6. Score sources and track contradictions
- [ ] 7. Refine draft (denoise)
- [ ] 8. Evaluate quality (score < 7? repeat 4-7, max 3 cycles)
- [ ] 9. Finalize

RESEARCH BRIEF
Topic: [Specific question]
Scope: [Included/excluded]
Key Questions:
1. [Primary]
2. [Secondary]
3. [Tertiary]
Constraints: [Limits]
Language: [Match user's language]
Write from existing knowledge only. Mark gaps:
[NEEDS VERIFICATION] - uncertain claims[RESEARCH NEEDED] - missing information[CONFIDENCE: LOW/MED/HIGH] - flag uncertainty levelsThis draft intentionally contains "noise" - the refinement loop will denoise it.
Attack your draft for:
Rate each issue 1-10 severity. See references/critique-framework.md.
Search budget by complexity:
CRITICAL: Think after EVERY search. After each web_search, pause and reflect:
REFLECTION:
- What key facts did I find?
- What gaps remain?
- Do sources agree or conflict?
- Is another search needed, or do I have enough?
Parallel research triggers - pursue multiple threads when:
See references/search-patterns.md for query techniques.
Score each source (1-100 confidence):
| Source Type | Base Score |
|---|---|
| Official documentation, peer-reviewed | 85-100 |
| Government/institutional reports | 75-90 |
| Established news outlets | 60-80 |
| Industry publications | 50-75 |
| Blogs, forums | 20-50 |
Adjust based on: recency, author credentials, citation quality.
Track facts with attribution:
FACT: [Statement]
SOURCE: [URL]
CONFIDENCE: [1-100]
DISPUTED: [Yes/No - conflicts with other sources?]
When sources contradict:
See references/source-evaluation.md for detailed guidance.
[NEEDS VERIFICATION] with sourced factsContext management: If accumulating too much research, compress raw notes into key findings before continuing. Discard redundant/low-value information.
Score 1-10 on:
Track across iterations:
QUALITY LOG:
Iteration 1: Comprehensiveness 5, Accuracy 4, Avg 4.5
Iteration 2: Comprehensiveness 7, Accuracy 6, Avg 6.5
Iteration 3: Comprehensiveness 8, Accuracy 8, Avg 8.0 ✓
If average < 7: Return to Step 4 (max 3 cycles). If score drops between iterations: Focus critique on what regressed.

Input: "Research the current state of nuclear fusion energy"
Research Brief:
Topic: Current state of nuclear fusion energy
Key Questions:
1. What are the leading approaches and projects?
2. What milestones have been achieved recently?
3. What are realistic timelines for commercial fusion?
Constraints: Focus on scientific/engineering progress, not policy
Draft Excerpt (before research):
Nuclear fusion has made significant progress [CONFIDENCE: LOW].
The National Ignition Facility achieved ignition [NEEDS VERIFICATION].
Private companies like [RESEARCH NEEDED] are also pursuing fusion.
Post-search reflection:
REFLECTION after search 1 (NIF ignition):
- Found: NIF achieved ignition Dec 2022, 3.15 MJ from 2.05 MJ input
- Source: Lawrence Livermore (official) - Confidence 95
- Gap: Private sector landscape still unknown
- Next: Search for private fusion companies
Source tracking:
FACT: NIF achieved fusion ignition December 2022
SOURCE: llnl.gov/news/...
CONFIDENCE: 95
DISPUTED: No
Quality log:
Iteration 1: Comp 5, Acc 4 → Need private sector + timelines
Iteration 2: Comp 8, Acc 7 → Good coverage, strengthen citations
Iteration 3: Comp 9, Acc 8 → Done ✓
Use: Complex questions, comparisons, due diligence, state-of-art surveys Don't use: Simple lookups (use web_search directly), opinions, creative writing
