🧠 来玩互动测验 →- What Is an Agent?Start with an example you already get
- How Does an Agent 'Think'?The think–act–observe loop
- Hands-on: Your First Tool-Calling AgentRead a minimal snippet + judge right from wrong
- What Context Is: The AI's DeskWhy 'good results are a byproduct of good context'
- Bringing the AI Reference Material: RAG in Plain WordsLet it look things up before answering, instead of guessing from memory

- Give the AI a RoleWhy a role / system prompt helps, and how to write a good one
- Write a 'Manual for the AI'Intro to design docs / project specs
- Getting Started with AI Coding ToolsWhat exactly do Cursor / Claude Code add over a normal editor
- Sync vs. Async AgentsWatch it work step by step, or send it off to run to completion and report back
- Semi-Async Workflows: How Far to Let GoWhich tasks you can hand off, which you must watch
- Why Long Context DerailsFeed it too much and it forgets and drifts—how to defend against it
- How to Design Good Tools for an AgentSmall and clear, single responsibility, well described
- The CLAUDE.md Pattern: Make It Remember the Project's RulesProject-level long-term memory / convention file
- How Teams Share AI KnowledgeDistill personal tricks into reusable team conventions
- Connecting MCP: Plug a Whole Row of External Abilities into the AgentMCP in plain words: a standard plug—connect once, get a row of tools
- What a Modern AI Terminal Looks LikeWhy it's designed this way
- Run Cautious or Run AggressiveTwo configuration styles, each with its own stage
- When to Let Go, When to Add a CheckpointDecide with 'cost of a mistake + reversibility'
- One Sentence Can Trick Your AgentPrompt injection: smuggled instructions, indirect injection, and least privilege
- Don't Put Secrets in the Prompt, and Don't Let It RoamCredential / secret leaks and SSRF in plain words
- When AI Says 'Security Scan Passed,' Don't Fully Trust ItFalse negatives: passing a scan doesn't mean it's actually safe
- Double-Insure the AI's OutputAutomated tests + human verification as a safety net together
- What Code Review Is Actually ReviewingCorrectness, maintainability, team conventions—each layer harder than the last
- How to Review AI-Written CodeAI confidently makes things up and over-engineers—reviewing it differs from reviewing people
- The AI Review Capability QuadrantHand the mechanically decidable to AI, keep the context-dependent for yourself
- From a One-Line Idea to a Reachable Web PageBreak a fuzzy idea into clear requirements the AI can get right in one go
- A High-Accuracy Generation Pipeline: How to Minimize ReworkIterate in small steps, skeleton before details, verify each step before continuing
- UI Automation Traps and ShortcutsThe fancier it is, the easier it derails; use screenshots and automation to save effort
- Deploy the App to ProductionShortest path: one-click deploy on a hosting platform, domain, environment variables and secrets
- Monitoring & Reliability BasicsLogs, error alerts, key metrics, and what to check first when it breaks
- AI-Native Ops: Let the Agent Watch Production for YouThe Agent reads logs, does first-pass triage, suggests fixes; the human makes the call
- Evaluation & Observability: How Do You Know If Your Agent Actually WorksOffline eval + online monitoring; execution-based grading + LLM judges (which are biased)
- RAG & Memory: Giving Your Agent Knowledge and a MemoryParametric + non-parametric memory, reduces (not eliminates) hallucination, plus chunking / lost-in-the-middle / seven pitfalls
- Multi-Agent: When to Split, When Not ToWorkflow vs. agent, when it fits, plus the 15x cost and errors that compound
- Cost & Latency: Making Your Agent Affordable and FastPrefill / decode, output is pricier, plus caching / batching / routing / compression / speculative decoding
- Install Claude Code: Your First Conversation in 10 MinutesIt's not a chat box. It's an assistant that can act on your computer
- Your First Build: A To-Do List Web PageState the goal, not the steps; check the result before the code
- State Requirements Clearly: User Stories and the "Not This Time" ListWhen AI gets it wrong, it's usually because you hadn't thought it through
- CLAUDE.md: Make It Remember Your Project RulesWrite it once, and it reads it on every launch
- Plan Mode: Talk It Through Before Touching CodeFor complex features, have it propose a plan first; you nod, then it writes
- See What It Changed: git and One-Line RollbackBreaking things isn't scary. Not being able to go back is
- Weekly Assignment: Publish Your To-Do List OnlineIt only counts as built when someone else can open the link
- What a Mini Program Is, Getting an AppID, Installing DevToolsOne hour of prep before you start; get it right and the rest goes smoothly
- Have Claude Code Generate the Mini Program SkeletonFour files, one page: get it running first
- Pages and Interaction: Move the To-Do List into the Mini ProgramData lives in data, changes go through setData, local saves use storage
- Data in the Cloud: WeChat CloudBase DatabaseSwitch phones and your data is still there, no server to rent
- Identifying Users: openid and Cloud FunctionsNo login page needed; WeChat already knows who they are
- Real-Device Preview and Debugging: Run It on Your PhoneWorking in the simulator does not count; working on the phone does
- Week Assignment: Review Checklist and Privacy Protection GuidelinesPassing review the first time takes a checklist, not luck
- Inflation: Why Your Money Doesn't Stretch as FarPurchasing power, prices, and moderate inflation
- Interest & Compounding: How Money Grows and Debt SnowballsThe intuition behind simple interest, compound interest, and the Rule of 72
- Supply, Demand & Prices: Why Things Go Up and DownSupply, demand, scarcity, and price
- Cash Flow & Living Within Your MeansIncome minus expenses equals what's left; budgeting is about seeing where your money went
- Good Debt vs. Bad Debt & the Emergency FundDebt that earns or carries low interest vs. high-interest debt for pure spending; build a 3-to-6-month cushion first
- Your Savings Rate Is What Really MattersThe share you keep, more than how much you earn, sets how fast you reach financial freedom
- Risk and ReturnHigh returns always come with high risk; "guaranteed high yields" is a danger sign
- Diversify, Don't Go All InDon't put all your eggs in one basket; diversification lowers single-point risk
- Compounding × Time × the Long Run + Spotting ScamsTime is compounding's friend; meanwhile learn the shared traits of Ponzi schemes, guaranteed-high-yield pitches, and pyramid recruiting
- What GDP, Unemployment, and Inflation Are Telling YouThe three most common economic indicators, and what each one measures
- What Central Banks Are Really Doing When They Raise and Cut RatesInterest rates are the economy's gas pedal and brake, shaping people's willingness to borrow and spend
- Economic Cycles: Booms and Busts Take TurnsThe economy has its seasons; expansion and contraction alternate, and it's closely tied to ordinary life
- Correlation ≠ CausationTwo things showing up together doesn't mean one caused the other
- Common Logical FallaciesSpotting the moves that "sound reasonable"
- How to Judge Whether Information Is TrustworthySelf-defense for information in the age of AI
- Premises and ConclusionsIn a passage, which sentence is the claim and which ones are the reasons backing it up
- Deduction vs. InductionReasoning that must be true, versus reasoning that's only "very likely"
- What Makes a "Good Argument"The premises must be true and the reasoning must hold up—you need both
- More FallaciesAppeal to emotion, ad hominem, false dilemma, and circular reasoning
- How Biases Quietly Skew Your JudgmentWhat confirmation bias and anchoring look like in everyday life
- Sunk Cost & Survivorship BiasMoney already spent shouldn't hijack the future, and looking only at success stories will lead you astray
- Reading Data Without Being FooledThe percentage trap, the average-number con, and scary-looking charts
- How to Evaluate a "Study" or "Expert Opinion"Sample size, correlation vs. causation, conflicts of interest, and reproducibility
- How to Argue ReasonablyAddress the issue not the person, read the other side charitably, and admit you might be wrong
- The Brain's Three Favorite ShortcutsConfirmation bias, the anchoring effect, and survivorship bias
- Emotions Aren't the Enemy—They're SignalsWhat emotions do, naming emotions, and how thoughts shape feelings
- Motivation and HabitsIntrinsic vs. extrinsic motivation, the habit loop, and how to build or break a habit
- The Base Rate Fallacy: Why Positive Does Not Mean SickStart with a hypothetical 10,000-person screening and separate sensitivity, false-positive rate, and positive predictive value
- Conformity and Social ProofWhy we do something just because everyone else does
- Three Principles of InfluenceHow reciprocity, commitment and consistency, and authority quietly steer you
- Group Effects: Bystanders and DeindividuationWhy more people often means no one helps, and how anonymity changes us
- How Memory Works, and Why We ForgetForgetting what you learned is normal—review before it's all gone
- Study Methods That Actually WorkActive recall, spaced repetition, and teaching it to someone else
- Procrastination and MotivationPutting off what you know you should do—and beating it with "just five minutes"
- Communicate WellListening, and using "I-statements" to express feelings instead of blame
- Self-Esteem and Self-EfficacyBelieving you can do it, built up one small success at a time
- Stress and Emotion RegulationCope instead of suppress, and start with the small things you can control
- Shot Sizes: Five Distances, Five EmotionsHow close the camera is decides how strongly the audience feels
- Camera Angle: The Subtext of Low & High ShotsWhere you put the camera secretly decides who has the power
- Camera Movement: A Moving Camera Is TalkingPush, pull, pan, track, follow — the five basic moves
- The Line: Why Your Dialogue Looks 'Off' After the CutThe 180° rule — don't jump over that invisible line
- The Core of a Story: Say It in One SentenceA good story = a person desperately wants something but can barely get it
- Three-Act Structure: Setup · Confrontation · ResolutionTwo turning points push the story forward
- Character: What They Want vs. What They Truly NeedThe spoken goal and the inner growth are often not the same thing
- Conflict & Obstacles: No Conflict, No DramaGive the hero an opponent, a wall, and stakes
- Scene & Beats: How to Write a Single SceneEvery scene needs someone who wants something, hits resistance, and ends changed
- Dialogue & Subtext: What's Unsaid Is the PointCharacters say one thing and mean another
- Composition: Directing Where the Audience LooksSymmetry, thirds, leading lines, negative space — the real rules beyond the rule of thirds
- Depth of Field & Focus: Leading the EyeBlurred background = 'look here'; all sharp = 'the info is all here'
- Foreground & Framing: Depth in a Flat ImageForeground builds layers; a frame-within-a-frame creates a 'peeking' feeling
- Three-Point Lighting: Make a Face Look Three-DimensionalKey, fill, and rim light — each does one job
- Light Direction & Quality: Hard vs. Soft, Front vs. BackWhere the light comes from, and how hard it is, sets the mood
- Color & Emotion: Warm/Cool and ComplementaryColor isn't just pretty — it's carrying emotion for you
- What Editing Really Is: You're Not Joining Shots, You're Directing the Audience's EyesA single cut decides what the audience sees next — and what they skip
- Continuity Editing: The Invisible Rules That Hide the CutThe 180° system + four 'stitching' tools that make every cut disappear
- Cut for Emotion: Walter Murch's Rule of SixGood editing has priorities — emotion is 51%, more than the other five combined
- Montage: Cutting 1+1 into a Third MeaningThe Kuleshov effect + Eisenstein's 'montage of collision'
- Rhythm: How Long the Shot Is, How It Joins, Where the Sound GoesDuration sets the pace, match cuts stitch time and space, J/L-cuts offset sound and picture
- Immigration: What Officers Ask, How You AnswerThey only care about four things — you only need short answers
- Hotel Check-in & Check-out: One Sentence, One Passport, One CardA reservation under your name — and the deposit isn't an extra charge
- Ordering & Paying: Two Phrases Cover the Whole MealOrder without pronouncing the dish — and don't mix up the check and the tip
- Directions & Transport: Understanding Beats AskingBlocks, "you can't miss it" — tune your ears to direction-speak first
- Shopping & Tax Refunds: "I'm Just Looking" Blocks Every Sales PitchTrying on, sizes, returns, refunds — 'in a medium' is the core pattern
- Emergencies: Lost, Stolen, or SickThe police report is your insurance lifeline — and never say 'drugs' for medicine
- Flight Day: Check-in Dialogue & Boarding CallsAt the airport, 'check' means checking bags — and a final call has no encore
- Nielsen's 10 Usability Heuristics: Ten Rules of Thumb for Systematically Spotting 'Hard to Use'Heuristic evaluation proposed in 1990, the 10 refined by factor analysis in 1994 — they are direction-pointing rules of thumb, not pixel-level design specifications
- Interaction Design Basics: Affordance, Signifier, Mapping and Feedback — Making 'Usable' Self-EvidentAn affordance is a relationship that isn't necessarily visible; signifiers are the perceivable cues that show how to operate. Bridge the gulfs of execution and evaluation, and use four types of constraints to make the right action the only action.
- Visual Hierarchy & Gestalt: Make Interfaces Read Right at a GlanceProximity, similarity, common region, closure and continuation decide 'what belongs together'; scale, contrast and whitespace decide 'what gets seen first' — when everything is emphasized, nothing is
- Information Architecture: The Four Systems That Make Things Findable — Organization × Labeling × Navigation × SearchHow content gets grouped, named, linked and searched — IA is the invisible skeleton; a feature users can't find might as well not exist
- Design Systems: The 'Single Source of Truth' for Product InterfacesFrom atomic design's five levels to design tokens — components are only the start; governance and adoption are the real battlefield. A system constrains inconsistency and liberates creativity
- Copywriting Fundamentals: Sell With Words, Don't Just Show OffGet clear on what copy is for — not to make people laugh or show off your prose, but to use words to drive attention, feeling, and action toward conversion: sell benefits not specs, write to one person, run the AIDA funnel from attention to action, and cut a pile of selling points down to one sharpest core message
- Headlines & Hooks: Most People Only Read the Headline — Use the Four Qualities and the Curiosity Gap to Stop Them and Hook ThemThe headline is the doorway to your copy — first use benefit/news/curiosity/quick-and-easy and the 4 U's to stop the right people, then use specific numbers and an information gap to build a hook; suspense should pull readers in, but the promise must be paid off in the body, or it's just clickbait the algorithm punishes
- Story & Emotion: Make Words Make People 'Feel' First — Then Share and BuyWhy high-arousal emotion drives sharing while sadness lowers it; use 'one concrete person' and show-don't-tell to spark feeling, then PAS to amplify the pain and BAB to ignite desire — while dodging the 'more tears is better' and fear-mongering traps
- Calls to Action & Conversion: Cashing Emotion and Value into a 'Click Now' ActionThe CTA is where copy cashes out — the Fogg model says Behavior = Motivation × Ability × Prompt, and a prompt only works when both motivation and ability are present; raise motivation with Cialdini's three levers, raise ability by cutting friction, write one clear low-friction primary CTA, and avoid choice overload and fake scarcity
- Viral Chinese Copy: From Li Jiaoshou's User-Centric View to Xiaohongshu's Four Elements — See Through the Formulas to the PrinciplesDon't write for yourself — pin down the reader's 'A point' first, then use the demand triangle (lack x target x ability) to spark need; the four elements of a Xiaohongshu hit (topic, cover, title, body) still rest on the same classic principles — formulas expire, principles don't
- Project Life Cycle & the Five Process Groups: the Road a Project Travels, and the Moves You Make on Every StretchThe life cycle is the road a project travels; IPECC is the set of management moves repeated on every stretch — start and finish properly, from charter to lessons learned, then choose predictive, adaptive, or hybrid by uncertainty
- Work Breakdown Structure (WBS): Use the 100% Rule to Decompose Scope into Work Packages You Can Estimate and ControlA deliverable-oriented, level-by-level decomposition — break down outcomes (nouns), not actions (verbs), stop at 8-80-hour work packages, and remember: if it's not in the WBS, it's not in the project
- Critical Path Method (CPM): Find the Chain Where Any Delay Delays EverythingBorn 1957–1959 when Kelley and Walker scheduled plant maintenance — the longest chain of dependent activities sets the shortest project duration, and only zero-float tasks are 'critical'
- Project Risk Management: Turning 'Something Might Go Wrong' into 'We Have a Plan'Risk includes opportunities and managing it is a continuous loop — identify with a register and 'cause → uncertain event → effect,' assess with the P-I matrix and EMV, respond with four strategies each for threats and opportunities, and keep contingency vs management reserves straight
- Agile & Scrum: From 'Left Over Right' to the Three Pillars, Three Accountabilities, Five Events, and Three ArtifactsThe Agile Manifesto doesn't reject documentation or plans — it ranks priorities; the Scrum Master is not a project manager and the Daily Scrum is not a status meeting — the skeleton and the myths, straight from the Scrum Guide 2020
- The Three Rhetorical Appeals: Who You Are × How You Make Them Feel × Whether Your Argument Holdsethos / pathos / logos work together — but argument is the foundation; pure emotion without reasoning becomes manipulation
- Structured Messaging: the Pyramid Principle + SCQA, so people grab your point in one sentenceAnswer first, governing point on top, group by category (MECE), logical progression — think bottom-up, then present top-down
- Storytelling in Speeches: Use One Concrete Person to Plant Your Point in the Audience's BrainStories really change the audience's brain chemistry (oxytocin) — but they must ride a tension arc, cast the audience as the hero, and carry one point per story; otherwise they're either dry and forgettable, or hollow emotional manipulation
- Stage Presence & Composure: You Don't Have to Kill Stage Fright — Delivery Can Be PracticedStage fright is common and trainable — steady your mind with preparation, the illusion of transparency, and reframing anxiety as excitement; then build delivery through voice and body — and don't believe in 7-38-55 or power posing
- Slides & Visualization: Put What Should Be Seen on Screen, and Say What Should Be HeardSlides are a 'glance medium' that aids you, not a script — use the redundancy / coherence / signaling principles, assertion-evidence, one-idea-per-slide, and data-ink to subtract, and dodge 'death by PowerPoint'
- Intuition Traps: Why the Answer That Pops Up in 3 Seconds Is So Often WrongFrom bat-and-ball to doubling lily pads — three CRT 'grade-school' questions fooled half of MIT; meet System 1's blurting, System 2's laziness, and the cognitive miser, and learn to hit the slow-thinking switch when it counts
- Probability Traps: Switching Wins 2/3, a Positive Test Means ~2%, and the Wheel Owes You NothingThe Monty Hall problem, the taxicab and the doctors' test, Monte Carlo 1913 and the hot-hand saga — answer in your head first, then see the breakdown, and load Bayesian intuition with natural frequencies
- Statistical Traps: Should You Armor Where the Bullet Holes Are? — Survivorship Bias, Simpson's Paradox, Regression to the Mean, and Charts That LieWald inferring the downed planes from the ones that returned, Berkeley's admission rates reversing in aggregate, flight instructors' illusion that scolding works — the numbers aren't faked, yet the impression can be entirely fake; rule out statistical artifacts before reaching for causal explanations
- Decision Traps: the Rigged Wheel, the Season Tickets You Must 'Get Your Money's Worth' From, and the Mug Nobody Would SellAnchoring, sunk cost, framing, loss aversion, and the endowment effect — irrelevant numbers hijack your bids, money already spent hijacks your choices, and the same numbers reworded flip the majority; get fooled once, get immune — even experts aren't exempt
- Four Classic Logic Traps: Linda, 2-4-6, the Four Cards, and the Letter K — Get Fooled Once, Get Immune85% fall for the Linda problem, only 21% crack 2-4-6 on the first try, and the abstract four-card task is solved by fewer than 10% yet 74% in a drinking-age setting — how similarity, positive instances, and ease of recall impersonate probability, evidence, and frequency
