What is store-update?

A release helper for downloading Windows Store MSIX packages, the installable format used by Microsoft Store apps, from a GitHub release and preparing update text.

Use it after publishing a release to download amd64 and arm64 packages, verify them, preview the Store update notes, and get upload instructions.

It removes the manual work of finding the right architecture packages, checking their file hashes, and copying release notes into the Store listing.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00100	$0.00988
Opus 5.5	$0.00040	$0.00395
Sonnet 5.5	$0.00020	$0.00198
Haiku 4.5	$0.00010	$0.00099

Measured 2mo ago against content hash 07c044ab8974, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

store-update 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/download_store_msix.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

CCX Desktop Store MSIX 下载与发布公告技能

适用场景

当用户在 GitHub Release 发布完成后，需要下载 Store MSIX 包、校验完整性、生成 Store 更新说明时使用本技能。典型输入：

"release 后下载两个 msix"
"帮我准备 Store 的 msix 和更新说明"
"下载 store msix 并生成发布内容"
"跑一下 desktop store update"

执行流程

1. 下载 MSIX 并校验

python3 .claude/skills/store-update/scripts/download_store_msix.py --download-dir ./store-msix

脚本会：

通过 GitHub API 读取最新 release 信息。
从 Release body 生成 Store listing releaseNotes 纯文本预览。
用 gh release download 下载两个 MSIX（amd64 / arm64）和对应 .sha256 到指定目录（gh 会自动走已登录的 auth，绕过代理）。
校验架构集合必须为 amd64 + arm64。
校验 sha256（如果 release 中存在 .sha256）。
输出下载结果摘要、文件路径和手动操作指引。

2. 打开下载目录

下载并校验完成后，用系统命令打开下载目录，便于用户直接拖拽上传：

open ./store-msix

3. 输出手动操作指引

下载完成后，向用户输出以下信息：

两个 MSIX 文件的本地路径。
SHA256 校验结果。
从 Release body 生成的 Store 更新说明预览。
手动操作指引：
- 打开 Partner Center
- 进入 CCX Desktop → Product release → 点击「Packages」行上传两个 MSIX
- 点击「Store listings」行 → 选择语言 → 在「What's new in this version」粘贴更新说明
- 返回后点击「Submit for certification」

默认产物匹配

当前 release workflow 生成两个 Store MSIX：

CCX-Desktop-${VERSION}-windows-amd64-store.msix
CCX-Desktop-${VERSION}-windows-arm64-store.msix

脚本要求最新 GitHub Release 中恰好匹配 amd64 与 arm64 两个 .msix，并优先读取同名 .sha256 进行校验。

常用参数

python3 .claude/skills/store-update/scripts/download_store_msix.py --help

常用选项：

--tag <tag>：指定 release tag，不使用 latest。
--allow-prerelease：允许 prerelease Release，默认拒绝。
--repo owner/name：指定 GitHub 仓库。
--download-dir <dir>：保留下载文件，便于手动上传。默认使用临时目录。
--store-release-notes "..."：手动覆盖 Store listing 更新内容。
--release-notes-file <file>：从本地文件读取 Store listing 更新内容。
--no-release-notes：不生成 Store listing releaseNotes 预览。
--release-notes-max-chars 1000：Store 更新内容最大长度，默认 1000。
--truncate-release-notes：超过长度时显式截断；默认超过长度会失败，避免静默丢内容。

输出要求

完成后输出中文摘要，至少包含：

GitHub release tag 和 URL。
Store 更新内容来源、长度和预览。
两个 MSIX 文件名、架构、本地路径和 sha256 校验状态。
手动上传指引（Partner Center 入口和操作步骤）。
如果失败，保留错误摘要。

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
