Example 1: Student looking for textbook
User: I need "Introduction to Algorithms" by CLRS
Claude:
[Runs search]
Found 3 editions:
1. 3rd Edition (2009) - PDF, 12.3 MB
2. 3rd Edition (2009) - EPUB, 8.1 MB
3. 2nd Edition (2001) - PDF, 15.2 MB
Which would you prefer? I recommend the 3rd edition EPUB for better readability.
Example 2: Researcher building bibliography
User: Find recent machine learning books
Claude:
[Runs search with --year 2023 --year 2024]
Found 15 recent ML books. Here are the top 5:
[Lists results]
Would you like me to:
1. Download any of these
2. Export as BibTeX
3. Create a reading list with summaries
Example 3: Format conversion need
User: I need this book in EPUB but only found PDF
Claude:
I can help with that:
1. First, let me search for EPUB versions
[Runs --extension epub search]
2. If no EPUB found, I can help you convert using Calibre
[Suggests calibre-cli conversion]

Behavioral testing methodology — test what users experience, not how code is structured. Use when writing tests, reviewing test quality, planning test strategy for new features, or when existing tests are brittle/verbose/coupled to implementation details. Triggers: writing tests, TDD, test review, "tests keep breaking", "too many mocks", "tests are verbose", test coverage planning, behavior-driven development.
Summon 8–12 fictional but statistically plausible people from Kyrgyzstan to judge your web app. They take screenshots, click around, get confused, get delighted, and write honest reviews in Russian. Output: a single .md report with embedded screenshots. Use when you need brutal UX feedback from people who ride marshrutkas.
Artemy Lebedev-style бизнес-линч design review. Opens the site in a real browser, screenshots everything, then tears it apart (or praises it) in his signature voice — brutal, specific, visual. Use when you want a no-bullshit design review, 'линч', 'lebedev review', 'artemy review', or 'roast my site'.
Autonomous experiment loop — modify code, measure, keep/discard, repeat forever. Based on Karpathy's autoresearch pattern. Use when there's working code + a measurable metric to optimize. Agent works while you sleep.
Iterative deep research agent — recursive breadth×depth tree search that accumulates learnings, generates follow-ups, and produces cited reports. Uses exa + serper + subagents. Use when user says 'deep research', 'investigate', 'deep dive', 'thorough analysis', or needs multi-source synthesis with depth.
Detect and fix design system leaks — default shadcn/bootstrap/MUI styling breaking through your brand. Use when: UI feels 'template-y', 'looks like shadcn', 'too generic', buttons are inconsistent colors, cards look default, or after shipping many features fast. Also: 'audit my design', 'check consistency', 'brand leak', 'fix the defaults'.
