Today’s Challenge Open whatever AI you normally use: ChatGPT, Claude, DeepSeek, anything. Pick an open-ended question. Ask it 3 times. The question is up to you. Some examples: “How do I build a reading habit?” “What are some Python tips for a complete beginner?” “How can I run better meetings?” You can rephrase it each time or paste the exact same wording. The key rule: start a fresh chat each time. Don’t follow up inside the same chat. Three new chats. ...

📖 This is Part 1 of 5 in the “AI Path L0→L1 Upgrade Guide” series. Series navigation will be updated once all parts are published. Introduction: Sound Familiar? I’ve watched a lot of friends use AI tools, and I keep noticing the same pattern. They’re not strangers to ChatGPT or Claude, using them casually from time to time, but their experience is wildly inconsistent. Sometimes the AI delivers a jaw-dropping answer; other times it completely misses the point, producing something unusable. ...

TL;DR: How does a person grow with AI? This post maps the journey from “opening a chat box for the first time” to “thinking in AI-native ways” across five stages—First Contact, Power User, Engineer, Architect, and Native. The essence of each stage isn’t about learning more tools, but about a shift in mindset: from passively accepting outputs, to actively designing inputs, to orchestrating multi-agent collaboration, and ultimately reshaping your own cognitive framework. The interactive path map at the end lets you explore each stage in full detail. ...

TL;DR: git rebase / checkout silently deletes untracked files in .gitignore, with no recovery; git stash -u does NOT stash git-ignored files. The fix: use git worktree to create a local-assets branch, storing design docs in a git-tracked safe space. Three commands handle daily use: dp-save.sh to save, --prune to clean, --restore to recover. Real project data shows zero document loss after introducing worktree. Full script at alexwwang/design-doc-worktree. One afternoon I had AI run git rebase -i to tidy up the last dozen commits. No conflicts. Clean terminal. Everything went smoothly. ...

TL;DR: Before releasing Aristotle v1.1, I found 18 bugs. Unit tests caught four (22%). The other 14 lived at the integration layer — component wiring, config propagation, process startup seams. Root cause analysis revealed six patterns: path/environment mismatch (5), registration omission (3), startup hang (2), silent failure (2), test-production path divergence (2), integration seam errors (4). The root cause isn’t harder problems — it’s AI bypassing the defenses that experience built. Implementation and review rhythms decouple, code appearance misleads quality judgment, and integration shifts from an explicit action to an implicit assumption. Includes an eight-dimension integration checklist and a 16-type bug roadmap at the end. ...

TL;DR: I switched from OMO to SLIM and ran it for 13 days. Average Tokens per message dropped 3.7% — practically flat. Broken down by task type: coding flat, writing +61%, review -53%, debug +121% (unreliable, tiny sample). Aristotle dropped 68%, but the main cause was an architecture rewrite, not the plugin. “Saving tokens” is not a global fact. It’s local. The real differences are in experience and architecture choices, not in token counts. ...

TL;DR: The inquiry protocol’s last line of defense is independent confirmation — a perspective free of confirmation bias that runs falsifiability testing to hunt for counterexamples. This post also covers how the protocol came to be (from 18 bugs of practice to a gap found while writing these articles) and plans for future reflexivity. In the previous post, I laid out the inquiry protocol’s seven conditions: three floor conditions (T1–T3) that force the AI to go deep enough, and four guardrails (HC1–HC4) that keep the inquiry process from spiraling out of control. This post covers the last line of defense, and how the protocol actually came to be. ...

TL;DR: The inquiry protocol sets seven conditions to keep AI’s 5-Why on track: T1–T3 are floor conditions (can’t stop until all three are met), HC1–HC4 are guardrails (prevent the process from spiraling). T2’s preventive counterfactual check is the most important design — preventive framing forces the inquiry to go deep, while counterfactual questions deliberately construct negation scenarios to counter confirmation bias. ← Previous post The last post diagnosed three problems when AI runs 5-Why: stopping too early (depth insufficient), single-path tracking (breadth insufficient), and confirmation bias (reasoning bias). These three are independent but tend to show up together: a shallow conclusion becomes an anchor, which simultaneously compresses the exploration space and biases evidence selection. This post designs the inquiry protocol: encoding the tacit judgment of “when to stop, when to keep going” that human experts use, into explicit rules that bring AI’s reasoning quality up to the standard 5-Why actually requires. ...

TL;DR: AI fails at 5-Why in three ways: stopping too early (insufficient depth), single-path tracking (insufficient breadth), and confirmation bias (reasoning distortion). The three are independent but tend to show up together — a shallow conclusion becomes an anchor that compresses the exploration space and biases evidence selection. This post uses a real case where all four rounds of attribution went wrong to dissect each failure mode. This post sits at the intersection of two series: “Taming AI Coding Agents with TDD” and “AI Root Cause Diagnosis.” ...

1. The Loop That Never Ends A few days ago, the Aristotle project [1], aimed at fully implementing the GEAR protocol, finally validated all its core technical pathways. The codebase had gone through its third refactoring, core features were working, and testing was complete. Right before merging the development branch into main for release, I ran a manual test and discovered that SKILL.md instructions weren’t being executed correctly: the model received the action but didn’t call task() to launch a background subagent. Instead, it loaded LEARN.md. From investigating this issue, more bugs kept surfacing: ...
