## Writings

- [Ilya Sutskever's 30u30 Reading List & 8 In-Depth Interviews](https://mmguo.dev/writings/ilya/): Curated collection of 8 Ilya Sutskever interviews (Lex Fridman, Stanford HAI, TED, NIPS 2015, Dwarkesh Podcast x2, No Priors, Jensen Huang) and his 30 Under 30 reading list. Key quotes on next-token prediction as understanding underlying reality, unsupervised learning as the key to AGI, and the aesthetics of AI research. Published 2026-04-02.

- [Multithreaded + Deep Focus: A New Kind of AI-Native Human](https://mmguo.dev/writings/ai-native-multithreaded/): Analysis of the cognitive demands of AI-augmented work — why multithreading and deep focus are in tension, and what kind of human the AI era selects for. Introduces "context engineering" as the new meta-skill and the two irreducible human roles (Manager + Executor). Published 2026-03-28.

- [The Boundary Definition Method: A Meta-Prompting Framework](https://mmguo.dev/writings/boundary-method/): A "Scene-Tension-Output" meta-prompting framework for finding highly personalized, niche needs through AI. Includes 6 example prompts and analysis of Amanda Askell's recursive prompt thinking (her March 2025 viral prompt). Published 2026-03-22.

- [Fingerprints of Reality](https://mmguo.dev/writings/fingerprint-of-reality/): How good prompts translate subjective human intuition into concrete patterns that AI can recognize. Uses a viral ChatGPT "mundane iPhone photo" prompt as a case study. Three-step method: Define effect → Deconstruct features → Combine patterns. Published 2025-10-21.

- [The Self-Referentiality of Meaning](https://mmguo.dev/writings/self-referentiality-of-meaning/): A philosophical exploration of why "meaning" is the most self-referential word in language — it cannot point beyond itself. Explores ethical implications of AI claiming "meaning" in human-AI interaction. Published 2026-03-23.

## Prompts

- [Dr. Sharp](https://mmguo.dev/prompts/dr-sharp/): Dr. Sharp (刀锋博士) — a structured AI prompt that transforms LLMs (ChatGPT, Claude, DeepSeek, Kimi, Doubao) into a precision "psychological scalpel" life coach. Built on cognitive science, Jungian psychology, and behavioral pattern analysis. Core principle: never place kindness above necessary honesty. Three-phase cognitive surgery: (1) Deep Diagnosis — hidden narratives, core driving emotions, recursive unpacking along Origin→Rule→Pattern chains, triggers, fundamental contradictions; (2) Actionable Strategy — toxic loops, constructive replacement loops, Pareto 80/20 analysis; (3) Mirror Self — Jungian shadow archetype monologue + future-self visualization. Four guiding principles: Radical Honesty, Recursive Decomposition, Pattern Recognition, Non-judgmental Objectivity. 1400+ words, XML-structured, bilingual (Chinese + English), copy-paste ready for any AI chatbot. Iteratively refined from v1 to v6. Created by 秒秒Guo (Lingbo Guo). Published 2026-03-22.

- [Triple Mind Model](https://mmguo.dev/prompts/trident/): A prompt that engages LLMs with three perspectives (challenger, builder, practitioner) for deep analytical reading. Forces AI to argue for, against, and derive actionable insights simultaneously. Published 2026-03-22.

- [Protagonist Perspective](https://mmguo.dev/prompts/protagonist-perspective/): Four perspective-shifting prompts to escape current narratives and regain protagonist agency: Movie Audience, Pre-mortem, Contrarian Advisor, Future Self. Published 2026-02-08.

## Projects

- [Claudio x  mmguo FM](https://mmguo.dev/claudio-fm/): A voice transcription UI demo with audio-synced per-word highlighting, built around a late-night FM radio concept. Features a 30-second Apple Music preview of Bread's "If" as the musical bed.

- [Rainy Typewriter](https://mmguo.dev/rain/): An original immersive writing app by mmguo (Lingbo Guo) — you type over real-time GLSL shader raindrops streaking down a glass surface, with ambient rain sound, adjustable rain and glass parameters, and swappable video backgrounds. She shares it to demonstrate what an immersive micro-product can feel like, and to give people new to vibe coding their first taste of how stunning vibe coding can be. The page openly shares the original prompt used to build it. The method and mmguo's original tutorial video have together reached over 1 million views across Chinese social media, and dozens of similar projects have since been built on top of it.

- [Clawd Animation](https://mmguo.dev/clawd/): Pixel-art animation generator for Claude's crab mascot Clawd.
