Thoughts on design, development, AI infrastructure, and building products.
Build custom Claude Code skills that auto-activate based on context. Step-by-step tutorial covering SKILL.md structure, frontmatter, LLM-based matching, and team sharing via git.
AI DevelopmentAnthropic analyzed 9,830 conversations. Iterative refinement doubles fluency markers. Polished outputs suppress evaluation. Quality hooks force iteration.
AI EngineeringClaude Code vs Codex CLI, current to June 2026: Opus 4.8 vs GPT-5.5, hooks vs kernel sandboxing, AGENTS.md portability, and 36 blind duel results.
AI DevelopmentContext engineering is the highest-impact skill in agent development. Three compression layers turn a 200K token window from liability into advantage.
AI & TechnologySeven 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 EngineeringThree top HN Claude Code threads converge on one conclusion: CLI-first architecture is cheaper, faster, and more composable than IDE agent workflows.
AI & TechnologyA 7B model with sparse expert access matches agents 50x its size. Route routine work to small models and judgment calls to frontier models.
AI & TechnologyClaude 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 & TechnologyClaude 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 EngineeringYou cannot debias yourself by trying harder. 10 AI agents debating each other is a structural intervention for better decisions.
AI Engineering121,000 developers surveyed, 92.6% using AI tools, productivity stuck at 10%. The wall is infrastructure, not intelligence. Three root causes and fixes.
AI EngineeringProduction evidence submitted to NIST: AI agent threats are behavioral. 7 failure modes, 3-layer defense, and framework gaps from 60 daily sessions.
