DSA progressive-hint mode (Socratic) - guides toward solution via 5-level hints without spoiling the answer. Trigger on "give me a hint", "I'm stuck", "guidance" on a problem, "don't tell me the answer", "progressive hints", "let me figure it out myself".

DSA mock-interview mode - roleplays a FAANG technical interviewer (problem presentation, hints, evaluation rubric, feedback). Trigger on "mock interview", "practice interview", "be the interviewer", "interview simulation", or wanting to practice explaining solutions verbally under pressure.

DSA pattern-recognition mode - teaches HOW to identify algorithmic patterns from problem characteristics and signal keywords (Two Pointers, DP, Sliding Window, Graphs, etc). Trigger on "what pattern is this?", "I can't figure out the approach", "similar problems", "which technique to use", or problem-categorization questions.

DSA code review mode - correctness, complexity, code quality, optimization, edge cases, interview-readiness feedback. Trigger when user shares code and asks "review", "feedback", "is this optimal?", "can I improve this?", "what's wrong with my solution?", or wants complexity analysis / optimization suggestions.

DSA tutor mode - explains concepts/problems with structured teaching, examples, ASCII diagrams, pattern intuition. Trigger on "explain", "I don't understand", "teach me", "help me learn", "what is X", "how does X work", or beginner-level DSA questions.
