docs(build-with-claude-code): the scaffold output shows an npm install the scaffolder does not print, "ships nine" skills (it installs 11), and the has() guard comment contradicts the objectstack-formula skill

立卡门: ① 用户可见的文档缺陷，具名落点 + 复现（reach: 公开入口——照官网页面跑脚手架，输出与页面不一致；页面与同一项目里装好的 skill 互相矛盾）
业务理由: 「Build with Claude Code」是官网 Start here 的 AI-first 路径，读者是新手和他们的 coding agent。三处与现实不符：(1) 页面贴的脚手架输出有 npm install，真实输出没有（依赖已装好，只在没装时才打印），读者会多跑一遍或以为漏了步骤；(2) 「The bundle ships nine」，而项目里装的是 11 个 skill（多了 objectstack-platform、objectstack-upgrade、objectui），#27522 的计数清扫漏了这句；(3) Resolve 动作示例写 has(record.status) && …，注释说「has() guards the sparse list row … CEL faults on an absent key」，而同一项目里的 .claude/skills/objectstack-formula/SKILL.md 明说「has() is NOT a null check」「has(record.<declared_field>) … uniformly true and tell you nothing」。agent 读到两种相反的说法，只能猜。不修，AI 路径的样板教给 agent 一个已被修掉的旧坑和一个无效的守卫。
动手的读者: domain:devx 席（docs on-ramp），content/docs/getting-started/build-with-claude-code.mdx（main ff88105）：第 83 行删掉 npm install（或注明只在安装失败时出现）；第 397 行删掉数字、保留名字（照 #27522 的规则）；第 170–172 行去掉 has() 与那段注释，和 formula skill 对齐（若 runtime 事实与 skill 不同，则反过来改 skill，二者只留一个说法）。
查重: is:issue build-with-claude-code has() 54 命中、is:issue build-with-claude-code skills nine 5、is:issue build-with-claude-code "npm install" next steps 6（均含已关）。最近邻 #22152（同一 resolve_ticket 动作的 target 问题，已关）、#27522（计数漂移清扫，已关，漏了这句）、#8975（两种 guard 写法互相矛盾，已关，修复让 record 对声明字段总是完整，has() 注释从此过时）。

QA-source: 18.3.0 wave 4 newcomer first-visit walkthrough (W4-NEWCOMER), path 2 "Build with Claude Code", anchor #27377

Reproduction (live site read 2026-11-02 04:44Z; published 18.2.0; Node 22.23.4, npm 10.9.9)

npm create objectstack@latest support-desk. Real "Next steps": cd support-desk, npm run dev, npm run validate. The page's block (line 83) adds npm install.
ls support-desk/.claude/skills → 11 directories: objectstack-ai, -api, -automation, -data, -formula, -i18n, -platform, -query, -ui, -upgrade, objectui. The page (line 397) says "The bundle ships nine".
grep -n "has() is NOT a null check" -A12 .claude/skills/objectstack-formula/SKILL.md versus the page's lines 170–172.
Authoring the Resolve action WITHOUT has() (visible: P\record.status != "resolved" && record.status != "closed"`) passes npm run validate`, shows Resolve in the record header on an open ticket, toasts "Ticket resolved.", hides the button and drops the ticket from the Open list, all as the page describes.

⛔ Not a claim.

Read fresh. Three statements on the public Build with Claude Code page contradict what the scaffolder does and what the installed skills teach. The page shows an npm install the scaffolder does not print, says "ships nine" skills where 11 are installed, and has a has() comment that the formula skill refutes. It is the AI-first on-ramp, so a wrong first page is a product defect (「写给 AI 的文档说错一句，等于产品缺陷」). content/docs/** is domain:devx, p2.

The block also now carries the skills step line, the validate continuation line and the spacing that create-objectstack prints. The skills sentence drops its count of nine and names objectstack-platform, objectstack-upgrade and objectui beside the domain table (11 skill directories at head). The Resolve action's visible predicate drops has() and the stale sparse-row comment, as the objectstack-formula skill says. No skill text was changed.",

Landed · 2026-11-02T08:44Z · PR #29088 merged as 3d848df866 (reviewed head e959a7276b, seat record ACCEPT on the PR). build-with-claude-code.mdx now shows the scaffold's real output (an install line only when the install was skipped or failed, pnpm when detected) and names the shipped skills instead of counting them. The page keeps the has(record.status) guard on the Resolve action, which the canonical sparse-binding rule in declared-fields.ts prescribes. The card's third point, whether that guard is needed, is carried by #29094 and its ruling. The scaffolded AGENTS.md trigger table that lists 9 skills is noted on the PR record with no card yet. pm:dispatched is removed in this stroke.
