Building Custom Skills for Claude Code: A Complete Tutorial
Build a code review skill from scratch. Covers directory structure, frontmatter fields, LLM-based matching, context budgets, and auto-activation.
AI DevelopmentWriting
Thoughts on design, development, AI infrastructure, and building products.
The Performance Blind Spot: AI Agents Write Slow Code
118 functions with slowdowns from 3x to 446x in two Claude Code PRs. AI agents optimize for correctness, not performance. The data on why, and what to build.
AI EngineeringAGENTS.md Patterns: What Actually Changes Agent Behavior
Which AGENTS.md patterns actually change agent behavior? Anti-patterns to avoid, patterns that work, and a cross-tool compatibility matrix for 8 tools.
AI DevelopmentContext Is the New Memory
Context engineering is the highest-impact skill in agent development. Three compression layers turn a 200K token window from liability into advantage.
AI & TechnologyThe Protege Pattern
A 7B model with sparse expert access matches agents 50x its size. Route routine work to small models and judgment calls to frontier models.
AI & TechnologyAnthropic Measured What Works. My Hooks Enforce It.
Anthropic analyzed 9,830 conversations. Iterative refinement doubles fluency markers. Polished outputs suppress evaluation. Quality hooks force iteration.
AI EngineeringClaude Code vs Codex CLI: When to Use Which
Architecture, safety, and extensibility compared side-by-side. Includes a decision framework based on 36 blind duels and daily production use of both.
AI DevelopmentThe CLI Thesis
Three top HN Claude Code threads converge on one conclusion: CLI-first architecture is cheaper, faster, and more composable than IDE agent workflows.
AI & TechnologyWhat Actually Breaks When You Run AI Agents Unsupervised
Seven named failure modes from 500+ autonomous agent sessions. Each has a detection signal, a real example, and a concrete fix. The taxonomy HN asked for.
AI EngineeringClaude Code as Infrastructure
Claude Code is not an IDE feature. It is infrastructure. 84 hooks, 48 skills, 19 agents, and 15,000 lines of orchestration prove the point.
AI & TechnologyThe Blind Judge: Scoring Claude Code vs Codex in 36 Duels
Claude Code vs Codex CLI, scored blind on 5 dimensions across 36 duels. The winner matters less than the synthesis combining both agents' strongest ideas.
AI EngineeringThinking With Ten Brains: How I Use Agent Deliberation as a Decision Tool
You cannot debias yourself by trying harder. 10 AI agents debating each other is a structural intervention for better decisions.
