A Skill is a persisted human-agent contract — agents write them, humans curate them, and knowledge stays alive in the loop. Why Skill marketplaces will inevitably fail, and why everyone needs their own Skill library.Tue, 14 Apr 2026 00:00:00 GMThttps://touchskyer.me/blog/skill-is-living-knowledge/https://touchskyer.me/blog/skill-is-living-knowledge/文档是 write-once-read-maybe-update-never。Skill 是 human-agent contract 的持久化形式——agent 写、人 curate、知识在循环中活起来。Skill marketplace 为什么必然失败，每个人为什么需要自己的 Skill library。Tue, 14 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/00-preface--en/https://touchskyer.me/book/silicon-team/00-preface--en/How one person builds an engineering team with AI agentsSun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/00-preface/https://touchskyer.me/book/silicon-team/00-preface/这本书讲的是一个人如何用 AI agent 构建一支工程团队Sun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/01-protocol-layer--en/https://touchskyer.me/book/silicon-team/01-protocol-layer--en/How CLI decouples memory from agents, and the three-layer distribution modelSun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/01-protocol-layer/https://touchskyer.me/book/silicon-team/01-protocol-layer/CLI 如何解耦 memory 和 agent，以及三层分发模型的设计Sun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/02-harness-native--en/https://touchskyer.me/book/silicon-team/02-harness-native--en/Constraint system design — how mechanical gates replace probabilistic judgmentSun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/02-harness-native/https://touchskyer.me/book/silicon-team/02-harness-native/约束系统设计——Mechanical Gate 如何替代概率性判断Sun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/03-multi-silicon--en/https://touchskyer.me/book/silicon-team/03-multi-silicon--en/Agent routing, Spawn vs Delegate, multi-agent orchestrationSun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/03-multi-silicon/https://touchskyer.me/book/silicon-team/03-multi-silicon/Agent routing、Spawn vs Delegate、多 agent 编排Sun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/04-autonomous-operation--en/https://touchskyer.me/book/silicon-team/04-autonomous-operation--en/The OPC pipeline, iterative review, and autonomous loopsSun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/04-autonomous-operation/https://touchskyer.me/book/silicon-team/04-autonomous-operation/OPC pipeline、iterative review、autonomous loopSun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/06-engineering-lessons--en/https://touchskyer.me/book/silicon-team/06-engineering-lessons--en/17 hard-won engineering lessonsSun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/05-startup-in-agent-era--en/https://touchskyer.me/book/silicon-team/05-startup-in-agent-era--en/From engineering to business — positioning, narrative, investment thesisSun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/05-startup-in-agent-era/https://touchskyer.me/book/silicon-team/05-startup-in-agent-era/从工程视角转向商业视角——定位、叙事、投资论点Sun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/06-engineering-lessons/https://touchskyer.me/book/silicon-team/06-engineering-lessons/17 个用血换来的具体教训Sun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/07-memory-to-book--en/https://touchskyer.me/book/silicon-team/07-memory-to-book--en/How 227 cards became a bookSun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/book/silicon-team/07-memory-to-book/https://touchskyer.me/book/silicon-team/07-memory-to-book/227 张卡片如何变成一本书Sun, 12 Apr 2026 00:00:00 GMThttps://touchskyer.me/blog/harness-engineering-ii--en/https://touchskyer.me/blog/harness-engineering-ii--en/Prompt engineering hits a cliff in long-run tasks.
