面向全球中文读者的 AI 内容、工具与实践。https://onballs.com/zh-Hanshttps://onballs.com/research/article-01-bookmarks-to-evidence/https://onballs.com/research/article-01-bookmarks-to-evidence/用具体问题、五格证据卡和反例，把收藏整理成可回查的判断。附2026年9月20日研究范围。Sun, 20 Sep 2026 00:00:00 GMThttps://onballs.com/research/article-02-ai-coding-acceptance/https://onballs.com/research/article-02-ai-coding-acceptance/从输入、异常、重复与恢复写出可检查的交付验收单。保留2026年9月20日故障注入的真实范围。Sun, 20 Sep 2026 00:00:00 GMThttps://onballs.com/research/article-03-automation-recovery/https://onballs.com/research/article-03-automation-recovery/区分未提交、已提交与未知状态，设计能接手的自动化恢复记录。附本地SQLite原型的实验边界。Sun, 20 Sep 2026 00:00:00 GMThttps://onballs.com/research/ai-task-acceptance-card/https://onballs.com/research/ai-task-acceptance-card/一张可直接融入日常使用的检查表：任务、输入、依据、输出、失败、恢复。它是编辑建议，不声称经过大规模效果验证。Mon, 07 Sep 2026 00:00:00 GMThttps://onballs.com/research/chinese-x-ecosystem/https://onballs.com/research/chinese-x-ecosystem/对 1,135 篇 X Article 收藏与 104 条中文公开样本的审计表明：工具卡、完整教程和赚钱故事已经成熟。OnBalls 更适合做来源、成本、复现和退出条件。Wed, 12 Aug 2026 00:00:00 GMThttps://onballs.com/research/competition-map/https://onballs.com/research/competition-map/OnBalls 不与产业新闻站或工具导航比发文量。长期空位是：为全球中文 builders/operators 做可核对、可复现、说清地区差异的决策研究。Wed, 12 Aug 2026 00:00:00 GMThttps://onballs.com/research/exit-code-not-complete/https://onballs.com/research/exit-code-not-complete/本地把唯一一次采集请求设为 HTTP 503 后，程序仍正常返回，结果是 0 条。需要区分：有新内容、成功但没有新增、只完成一部分、请求失败。Mon, 07 Sep 2026 00:00:00 GMThttps://onballs.com/research/first-research-questions/https://onballs.com/research/first-research-questions/从现有资料库优先挑十个研究问题。它们比单条爆款更适合做成可更新的中文判断。Wed, 12 Aug 2026 00:00:00 GMThttps://onballs.com/research/metr-measurement-boundary/https://onballs.com/research/metr-measurement-boundary/METR 2026-02-24 讨论了选择偏差和工时测量限制。它是测量方法信号，不能当成 2026 年 9 月所有 AI 工具的总体效率或失败率。Mon, 07 Sep 2026 00:00:00 GMThttps://onballs.com/research/n8n-human-review/https://onballs.com/research/n8n-human-review/2026-09-07 核验 n8n Tools Agent 文档：可在特定工具执行前要求人批准或拒绝。猜测路径返回 404。超时、重试和重复调用尚未实测。Mon, 07 Sep 2026 00:00:00 GMThttps://onballs.com/research/notebook-web-import/https://onballs.com/research/notebook-web-import/Google 笔记工具帮助页写明：Import through Web URL 只提取文字，不包含图片、嵌入视频和子页面。本篇是文档解读，不是账号内实测。Mon, 07 Sep 2026 00:00:00 GMThttps://onballs.com/research/tests-passing-not-acceptance/https://onballs.com/research/tests-passing-not-acceptance/2026-09-07 本地审计：39 项既有离线测试全部通过，一份合法的 38 条记录文件仍然导入失败。json.loads 能解析，splitlines 会把文本拆开。Mon, 07 Sep 2026 00:00:00 GMThttps://onballs.com/research/value-filter/https://onballs.com/research/value-filter/发现时保持宽口径，评价单位从单帖改成读者研究问题。十一条价值维度不相加；八道闸门之后只路由到多数人、特定人群、只观察或隔离。Wed, 12 Aug 2026 00:00:00 GMThttps://onballs.com/research/wide-in-strict-out/https://onballs.com/research/wide-in-strict-out/发现层尽量宽，成功机制单独学习，证据层严格，产品层重新创作。复制的是问题选择和验证方式，不是别人的文字、模板或数据库。Wed, 12 Aug 2026 00:00:00 GMThttps://onballs.com/research/x-metrics-are-not-customers/https://onballs.com/research/x-metrics-are-not-customers/X 帮助中心说明：views 可包含重复浏览和作者自身浏览。平台也限制重复垃圾内容和人为操纵互动。Mon, 07 Sep 2026 00:00:00 GMThttps://onballs.com/research/mcp-2026-protocol/https://onballs.com/research/mcp-2026-protocol/2026-07-28 版 MCP 去掉协议级会话后，更适合学习与低风险试点；付款、发布和敏感数据操作仍取决于实现方的控制面。Wed, 12 Aug 2026 00:00:00 GMThttps://onballs.com/research/why-not-tool-directory/https://onballs.com/research/why-not-tool-directory/旧收藏库可以按主题找候选，不能按热度或自动分类直接发布。工具目录越来越容易被 AI 搜索替代；OnBalls 要交付的是核验过的判断。Wed, 12 Aug 2026 00:00:00 GMThttps://onballs.com/research/evidence-four-dimensions/https://onballs.com/research/evidence-four-dimensions/公开站不用旧书签分类驱动。每篇只有一个主主题；形式说明交付形态；证据说明能承诺到哪一步；状态决定能不能公开。Tue, 11 Aug 2026 00:00:00 GMT
