## AI Agent
- [Claude Tag Deep Dive: From Shared Slack AI to an Organizational Agent Runtime](https://cubxxw.com/ai-agent/posts/claude-tag-organizational-agent-runtime/): Claude Tag matters less as a Slack entry point than as an organizational agent runtime built from shared identity, durable memory, asynchronous execution, proactive triggers, and audit controls.
- [Common Sense Is Not the Mechanism: Rebuilding Industries Around Demand, Constraints, and Scarcity](https://cubxxw.com/ai-agent/posts/common-sense-ai-industry-reconstruction/): Common sense compresses repeated experience into a stable rule of thumb. It can lead us toward a mechanism, but it cannot replace the mechanism, its boundary, counterexamples, or a falsifier.
- [Forgetting Is Harder Than Remembering: Why a Living System Must Know When to Let Go](https://cubxxw.com/ai-agent/posts/2026-07-31-forgetting-is-an-ai-system-capability/): Cheap storage makes forgetting a core AI capability. This essay designs auditable decay, archiving, and revocation for long-running AI memory systems.

- [Open Design 0.16.1: A Design Harness for Coding Agents](https://cubxxw.com/ai-agent/posts/open-design/): Open Design is a design harness rather than a model. It connects coding agents and model providers to file-based design knowledge, then turns briefs into editable artifacts.
- [Claude Code Playbook: 10 Configurations for Reliable Agent Workflows](https://cubxxw.com/ai-agent/posts/claude-code-boris-121-tips-playbook/): Plan mode and Auto mode solve different problems. Plan exposes decisions before edits; Auto reduces execution-time permission prompts through a separate safety classifier.
- [Loop Engineering for Solo Builders: Verifiers, State, and Safe Automation](https://cubxxw.com/ai-agent/posts/prompt-loop-engineering-practice/): A loop needs only three things: one task, one check, one stopping condition. Model choice, frameworks, MCP — all secondary. The real work is making the check real and defining when to stop.
- [A Solo Creator's AI Video Editing Pipeline That Actually Works](https://cubxxw.com/ai-agent/posts/solo-creator-video-pipeline/): For a solo creator, video is mainly a distribution layer. The useful question is not whether a cut looks expensive, but whether it carries something only you could have learned.
- [When Anyone Can Build the Thing, "He Built It" Becomes the Signal](https://cubxxw.com/ai-agent/posts/super-individual-stack-reputation/): Building trust requires consistency over time, and time cannot be compressed — this is the one constraint AI cannot take off your hands, and the entire reason reputation is the last layer standing.
- [Distribution for Solo Builders: Your Readers Can't Be Copied](https://cubxxw.com/ai-agent/posts/super-individual-stack-distribution/): A good product does not distribute itself. When building gets cheaper, discovery, relevance, and repeated proof become a larger part of the work.
- [AI Writes Requirements for Free, and That's the Most Dangerous Part](https://cubxxw.com/ai-agent/posts/super-individual-stack-judgment/): Execution cost going to zero doesn't shrink the price of a wrong direction — it amplifies it. The build cycle itself used to be your mid-course wake-up buffer, and that buffer is gone.
- [I Ran Ten Agents Overnight, Woke Up to Ten PRs, and Then I Got Stuck](https://cubxxw.com/ai-agent/posts/super-individual-stack-production/): Every advance in the production layer is a public good distributed to the whole industry at once. When you get 5x faster, so do your competitors — so equip this layer to "good enough" and stop.
- [The Four-Layer AI Stack for Super Individuals: What Actually Compounds](https://cubxxw.com/ai-agent/posts/super-individual-stack-four-layers/): Use one investment test: when this capability improves, does the gain become broadly available, or does it remain specific to your work and relationships?
- [Designing devbox-doctor: A Safer Mac Toolchain Audit](https://cubxxw.com/ai-agent/posts/devbox-doctor-design/): Developer machines accumulate three kinds of debt: tools that appear dormant, overlapping toolchains that may or may not conflict, and data left behind after an uninstall. None can be judged safely from a filename alone.
- [Agent Skill Design: What a Dangerous SKILL.md Taught Me](https://cubxxw.com/ai-agent/posts/designing-valuable-agent-skills/): A need is worth turning into a Skill only when three conditions hold at once - the workflow recurs, one step genuinely requires model judgment, and the output has a concrete deliverable. Missing any one, write a plain script or a plain prompt instead.
- [Building an AI Knowledge Base: From Notes to Executable Workflows](https://cubxxw.com/ai-agent/posts/info-to-creation-arsenal/): Internal and external are two separate systems. The internal knowledge base is an arsenal (methodologies, playbooks, battle records); external platforms are battlefields (audience-facing work). The arsenal stays private, ammunition flows out one way, feedback flows back one way.
## Engineering
- [Argo CD in Production: GitOps Sync, ApplicationSets, Rollbacks, and Security](https://cubxxw.com/engineering/posts/argo-cd/): Argo CD is a declarative continuous-delivery controller for Kubernetes. It compares desired and live state; it does not replace builds, tests, image scanning, or rollout analysis.
- [Kubernetes Resources and Learning Path Summary](https://cubxxw.com/engineering/posts/kubernetes-learning/): Source code reading is essential for advancing in Kubernetes; start with Docker and Linux fundamentals before proceeding.
- [Troubleshooting Guide for OpenIM](https://cubxxw.com/engineering/posts/troubleshooting-guide-for-openim/): Effective troubleshooting follows a systematic process: identify the problem through logs and testing, locate the root cause by tracing execution flow, and solve based on code understanding.
- [Navigating the Open Source Landscape](https://cubxxw.com/engineering/posts/navigating-the-open-source-landscape/): Open source welcomes contributors at all skill levels; basic knowledge and persistence matter far more than being an expert.
- [Go Directives & Automation Tools Deep Dive](https://cubxxw.com/engineering/posts/directives-and-the-use-of-automation-tools/): Go provides go:generate directive to automatically create repetitive project-specific code during development before compilation, significantly reducing boilerplate and manual errors
- [Concurrent Type Checking and Cross-Platform Development in Go](https://cubxxw.com/engineering/posts/concurrent-type-checking-and-cross-platform-development-in-go/): Go's integer type varies by architecture—int is int32 on 32-bit systems and int64 on 64-bit systems, causing overflow bugs that require platform-specific type checking.
- [OpenIM: Version Control & Testing Workflow](https://cubxxw.com/engineering/posts/openim-building-an-efficient-version-control-and-testing-workflow/): OpenIM enforces strict branch management with main as stable, release branches for production versions, and PR testing branches requiring rigorous code review and automated testing before merge approval.
- [GitOps & Kubernetes Deployment Strategies](https://cubxxw.com/engineering/posts/gitops-practice-theory-part/): GitOps combines Git as single source of truth with Kubernetes Operators to automate deployment from version control to clusters
- [Deployment and Design of Management Backend and Monitoring](https://cubxxw.com/engineering/posts/deployment-and-design-of-management-backend-and-monitoring/): OpenIM supports multiple deployment strategies including Docker, source code, Kubernetes, each optimized for different environments and scalability needs.
- [Hugo Advanced Tutorial](https://cubxxw.com/engineering/posts/hugo-advanced-tutorial/): Hugo templates leverage Go's html/template with automatic HTML escaping and pipeline syntax, where dot notation manages context through hierarchical data access.
- [Kubernetes for Kustomize Learning](https://cubxxw.com/engineering/posts/kubernetes-for-kustomize-learning/): Kustomize enables declarative Kubernetes configuration customization through patches without modifying original YAML files, maintaining base application settings across environments.
- [OpenIM Use Harbor Build Enterprise Mirror Repositories](https://cubxxw.com/engineering/posts/openim-use-harbor-build-enterprise-mirror-repositories/): Harbor enables enterprises to build private container registries with Helm and Cert-manager for secure HTTPS-based image storage and CI/CD pipeline integration.
- [Learn About Automated Testing](https://cubxxw.com/engineering/posts/learn-about-automated-testing/): Automated testing ROI increases over time as maintenance costs remain fixed while tests run repeatedly across multiple environments and browsers.
- [Deep Dive into Kubernetes CNI, CRI, CSI Components](https://cubxxw.com/engineering/posts/deep-dive-into-the-components-of-kubernetes-cni-csi-cri/): CRI is a gRPC-based interface that allows Kubernetes to support multiple container runtimes, with containerd being the optimal choice over Docker and CRI-O.
- [Kubernetes Control Plane - Detailed Analysis of Kubelet](https://cubxxw.com/engineering/posts/deep-dive-into-the-components-of-kubernetes-kubectl/): Kubelet runs on each Kubernetes node managing Pod lifecycles, handling container operations including image pulling, startup, monitoring, and status reporting to the API Server
## Growth & Life
- [September 2026 Thought Notes: Architecture, Temples and First Principles](https://cubxxw.com/growth/posts/2026-09-thought-notes/): Claude's message protocol makes a suspended tool call impossible inside one turn, so optimistic execution needs an explicit rollback path.
- [August 2026 Thought Notes: Agent Harness, Product and Self-Knowledge](https://cubxxw.com/growth/posts/2026-08-thought-notes/): August was mostly spent building agent harnesses: permissions, evaluation, memory and the boring plumbing that decides whether an agent is usable.
- [AI Made Me Smarter—and Slower to Meet Reality](https://cubxxw.com/growth/posts/2026-08-15-ai-made-me-smarter-later-to-reality/): AI can rapidly complete concepts, architectures, and plans while delaying falsifiable feedback. A 48-hour task shows how to let reality answer sooner.

- [I Don't Have an Execution Problem. I Need a Battlefield That Can Say No](https://cubxxw.com/growth/posts/2026-08-03-a-battlefield-that-can-say-no/): High output disproved my diagnosis of weak execution. What I lacked was an external result with the authority to reorder, stop, renew, or redirect the work.

- [Reading Hongyi in Quanzhou: Seeing Through, Then Taking Life Seriously](https://cubxxw.com/growth/posts/2026-08-03-hongyi-quanzhou-game-of-life/): In Quanzhou, Master Hongyi’s Vinaya practice and a Buddhist temple’s Hindu pillars changed how I understand play, commitment, and the choice to keep building.

- [The Scoreboard You Choose Will Eventually Choose You: How Incentives Reshape an Organization](https://cubxxw.com/growth/posts/2026-07-31-incentives-colonize-founders/): Metrics do more than measure organizations: they train attention and ethics. This essay shows founders how to audit incentives before they become culture.

- [A Second Brain Preserves Your Decision Function](https://cubxxw.com/growth/posts/2026-07-31-second-brain-as-survival-strategy/): A second brain used over many years records a sequence of choices, revealing what we repeatedly protect, avoid, and require before changing our minds.
- [The Opposite of Freedom Isn’t Constraint—It’s the Defaults That Live Your Day for You](https://cubxxw.com/growth/posts/2026-07-31-freedom-and-defaults/): Freedom is not the absence of schedules; defaults can quietly live the day for us. Three deliberate choice points help reclaim agency without rigid control.

- [When Generation Becomes Infinite, Authentic Experiences Begin to Command Value](https://cubxxw.com/growth/posts/2026-07-31-reality-becomes-scarce-after-ai/): AI can generate endless content but cannot bear experience’s cost. Authentic creation therefore depends on embodiment, verification, and ethical boundaries.

- [Risk Preference Isn't About Enjoying Danger: What Truly Enables Taking a Bet](https://cubxxw.com/growth/posts/2026-07-31-risk-is-not-danger/): Cave danger and social silence are different risks. This essay reframes courage around ambiguity, exposure, and repeated bets so no rejection can define you.

- [The Cost of Observation: Why the More You Understand, the Harder It Is to Enter Life](https://cubxxw.com/growth/posts/2026-07-31-the-observer-cannot-enter-life/): Observation protects us through distance, but can keep love and action from beginning. A four-step rhythm reconnects clear judgment with lived contact.

- [Creators Don’t Lack Applause—They Lack an Accurate Witness](https://cubxxw.com/growth/posts/2026-07-31-creators-need-accurate-witnesses/): Creators need more than applause: they need precise evidence that a work arrived. Four kinds of readers reveal what praise, critique, and silence cannot.

- [Records Are Not Mirrors, But Scissors: What Tool You Use Ultimately Shapes Who You Become](https://cubxxw.com/growth/posts/2026-07-31-recording-tools-shape-the-self/): Note-taking tools do not merely preserve experience; they edit attention and identity. A two-stage practice keeps facts separate from later interpretation.

- [Environment as the Hidden Author: Why Moving Cities Feels Like Becoming Someone Else](https://cubxxw.com/growth/posts/2026-07-31-environment-is-the-hidden-author/): The same person changes across cities. This essay shows how environments shape behavior, while preserving responsibility and room to redesign daily life.

- [When Distance No Longer Changes You: What Keeps Life Moving After Exploration Fails](https://cubxxw.com/growth/posts/2026-07-31-when-exploration-stops-changing-you/): When novelty fades, travel must be judged by the relationships and obligations that still survive departure—not by distance, shock, or cities collected.
