objectstack: Skill for Claude Code

.claude/skills/checklist-author/SKILL.md

checklist-author is a skill for Claude Code from objectstack-ai/objectstack. It costs 135 tokens per session (1,005 once invoked), scanned A, original, Apache-2.0.

A process for auditing a platform’s test checklist and adding missing coverage. Test coverage means how much of the platform’s behavior is represented by actual tests.

In plain words
What is it for?
Use it to inspect console screens, specifications, routes, runtime behavior, built-in apps, and documentation, then add verified checklist items and update the coverage record.
Why use it?
It helps reveal features that have no honest test, remove outdated exceptions, and avoid claiming coverage when a required test fixture does not exist.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

checklist-author scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Checklist author —— 让测试清单保持诚实的 coverage sweep

规范方法住在 docs/qa/platform-checklist/SWEEP.md —— 先读它、照它执行;本技能 只是触发器与编排契约,不是流程的第二份拷贝。

你要产出什么

一份对 docs/qa/platform-checklist/ 的增量:areas/*.json 里新增/扩充的测试项、 对账后的 coverage.json、追加进 FOLLOW-UPS.md 的缺陷/文档漂移 —— 全部在 node scripts/check-platform-checklist.mjs 下校验为绿,并按 AGENTS.md (worktree-first,PD#11)落在任务分支上。

编排契约 —— 只写 SWEEP 没有的

六步流程照 SWEEP.md「How to run it」执行,⛔ 这里不复述。它没有、而这一轮必须成 立的三条:

  1. Worktree 先行(PD#11):git fetch origin main && git worktree add --no-track ../objectstack-<task> -b <branch> origin/main。全部编辑落在那里;派发任何 agent 之前先读清单现状。
  2. 只有编排者碰 coverage.json 与 scripts/。 hunter 一个文件都不写,writer 一 个区文件一人 —— 这是并行 agent 之间唯一的串行化依据。
  3. 本技能的简报是假设,源码才是真相 —— 每个测试项按 README.md「Item anatomy」 的契约写;缺 fixture 记 blocked/knownGaps,永不伪造覆盖。

缺项写成 planned 项,不写成注释

sweep 发现「定义要求、平台还没有」的能力,写成该区的 status: "planned" 项(title · priority · personas,since: null 或目标 release,⛔ 无 steps);注释没有 id,派发时指 不到。它是 coverage.json 的合法映射目标但⛔ 不算覆盖:只映射到它的种类仍报 UNMAPPED。

planned → active 只由一次判 pass 的运行记录兑现 —— steps/acceptance 随实现 PR 落 地,跑过才翻状态(bump revision、追 history);⛔ 代码落地就翻 = 账本开始虚报覆盖。

规模指引

一轮全量 sweep ≈ 6 个 hunter + 8 个 writer agent。范围化的问题(「X 有测试吗?」) 只在相关角度跑一个 hunter,对清单核验后只补缺的 —— 契约相同,舰队更小。

没有子代理工具时,按角度顺序跑 —— 并在交付里声明这一轮是顺序执行的。 会话里不 存在 Task/子代理工具是允许的退化路径,不是阻塞;六个角度仍要逐个走完,一个都不省。 但 SWEEP.md 的全部主张是「不同角度捕获不同的遗漏类,因为读者彼此独立」:塌缩成 一个读者后,补上的测试项依然成立,「没有别的遗漏」这个结论不再成立 —— 不声明,就 没人分得清一轮降级的 sweep 和一轮完整的 sweep。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
