Conduct exhaustive, citation-rich research on any topic using all available tools: web search, browser automation, documentation APIs, and codebase exploration. Use when asked to "research X", "find out about Y", "investigate Z", "deep dive into...", "what's the current state of...", "compare options for...", "fact-check this...", or any request requiring comprehensive, accurate information from multiple sources. Prioritizes accuracy over speed, cross-references claims across sources, identifies conflicts, and provides full citations. Outputs structured findings with confidence levels and source quality assessments.
npx skill4agent add petekp/claude-code-setup deep-research| Tool | Best For | Limitations |
|---|---|---|
| WebSearch | Current events, recent information, broad topic discovery | Results may be outdated, SEO-influenced |
| WebFetch | Reading specific URLs, extracting detailed content | Requires known URL |
| Playwright browser | Interactive sites, paywalled content (if logged in), complex navigation | Slower, requires more tokens |
| Context7/MCP docs | Library/framework documentation | Only indexed libraries |
| OpenAI docs MCP | OpenAI API specifics | OpenAI only |
| Grep/Glob/Read | Codebase research, finding implementations | Local files only |
1. WebSearch with multiple query variations
- Try 3-5 different phrasings of the core question
- Include technical terms AND plain language
- Search for "[topic] official documentation"
- Search for "[topic] research paper" or "[topic] study"
2. Identify authoritative sources from results
- Official documentation sites
- Academic papers / research institutions
- Industry standards bodies
- Recognized experts in the field
3. Check specialized tools
- Context7 for library/framework docs
- OpenAI docs MCP for OpenAI-specific topics
- GitHub/codebase for implementation details| Source Type | Strategy |
|---|---|
| Documentation | Read relevant sections fully; note version/date |
| Research paper | Abstract, conclusion, methodology in that order |
| News article | Check publication date, author credentials, cited sources |
| Blog post | Verify claims independently; note author's expertise |
| Forum/Q&A | Check answer date, votes, accepted status; verify independently |

### Conflicts & Uncertainties
- [Area of disagreement]: Source A claims X [1], while Source B claims Y [2]. [Analysis of why they differ]
### Source Quality Assessment
| # | Source | Type | Authority | Recency | Notes |
|---|--------|------|-----------|---------|-------|
| 1 | [URL] | Official docs | High | 2024-01 | Primary source |
| 2 | [URL] | Research paper | High | 2023-06 | Peer-reviewed |
| 3 | [URL] | Blog | Medium | 2024-03 | Author is [expert] |
### Gaps & Limitations
- [What couldn't be verified]
- [Areas needing more research]
### Citations
[1] [Full citation with URL]
[2] [Full citation with URL]
...| Level | Criteria |
|---|---|
| High | 3+ independent authoritative sources agree; no conflicts |
| Medium | 2 sources agree, or 1 highly authoritative source; minor conflicts |
| Low | Single source, or significant conflicts between sources |
| Uncertain | Sources conflict significantly; unable to determine truth |
The API rate limit is 60 requests per minute [1], though this can be increased
for enterprise accounts [2].

[2] OpenAI Enterprise FAQ, https://openai.com/enterprise, accessed 2024-01-15| Anti-Pattern | Why It's Bad | Instead |
|---|---|---|
| Single source | No verification | Always find 2+ sources |
| Uncited claims | Unverifiable | Every fact needs a source |
| Assuming first result is best | SEO != accuracy | Evaluate source quality |
| Ignoring conflicts | Hides uncertainty | Report all positions |
| Outdated sources | Information decay | Check publication dates |
| Trusting AI summaries | May hallucinate | Go to primary sources |
| Stopping early | Incomplete picture | Research until diminishing returns |
