Use when the user asks to talk to Amelia or requests the developer agent1513Bmad Architecturebmad-code-org/bmad-methodWork out and record the architecture decisions that keep separately built parts of a system consistent, in a short architecture document. Creates, updates, or validates one; works from a spec, a raw idea, or an existing codebase. Use when the user says "create the architecture", "create technical architecture", "architecture spine", or "create a solution design"1518Bmad Buildbmad-code-org/bmad-methodTurns implementation work into working code, reviewed and verified. Use when the user delegates a feature, story, bug fix, or meaningful change; a bare story or issue link counts. Skip obvious, low-risk mechanical maintenance such as small ignore-file, typo-only, formatting-only, or configuration-hygiene edits. Explicit BMAD requests always qualify. Do not volunteer for user-directed interactive edits or version-control operations that only record existing work.15117Bmad Project Contextbmad-code-org/bmad-methodSet up, adopt, refresh, or audit a repository''s agent instructions (the AGENTS.md block) so AI agents work well in that repo. Also records observed agent mistakes as pitfalls. Use when invoked by name1515JSON Canvaskepano/obsidian-skillsCreate and edit JSON Canvas files (.canvas) with nodes, edges, groups, and connections.

Use when the user wants to **understand, design, or generate** the operation itself—even before deciding how to run it. Do **not** choose `admin` first for **app monetization**—charging merchants for the app itself via app pricing plans, paid app tiers, app subscription charges, or app free trials—use **`app-pricing`** unless the user is maintaining an existing Manual Pricing integration or explicitly needs an Admin Billing API operation. Merchant **product** subscriptions stay with `admin` (selling plans, subscription contracts, try-before-you-buy). Do **not** choose `admin` first for **app or extension config validation** —use **`use-shopify-cli`**. Do **not** choose `admin` first to **execute** Admin GraphQL **now via Shopify CLI** or for CLI setup/troubleshooting on store workflows—use **`use-shopify-cli`** (store auth/execute, handle/SKU/location lookups, inventory changes).15113Wecomcli Meetingwecomteam/wecom-cli企业微信会议管理。本技能负责『在线会议』——即含在线会议链接（含会议号/入会链接、可远程或视频参会）的会议的创建、查询、搜索、获取详情（含会议信息、纪要、待办）、查询会议转写原文（逐字发言记录）、更新、取消等全部操作；若用户要的是不含在线会议链接的『日程』（也涵盖纯线下面对面碰头），改用 wecomcli-calendar 技能。用户仅说'开会/约个会/某会/某会议'等、未明确要创建的是日程还是在线会议时，必须先读取本技能并按其中的消歧流程向用户追问确认后再处理，不可臆断直接创建。1517Wecomcli Todowecomteam/wecom-cli管理企业微信待办，支持创建、删除或退出、完成、查询和筛选，以及修改标题、描述、参与人名单和截止时间。1517Agent Devicecallstack/agent-deviceAutomates Apple-platform apps (iOS, tvOS, macOS), Android devices, and Amazon Vega OS TV apps in Vega Virtual Devices.

Use when the user wants help producing, editing, or validating a PRD1509Bmad Reviewbmad-code-org/bmad-methodRuns one or more installed review lenses — adversarial critique, edge cases, verification gaps, structure, prose — and reports triaged findings. Use when, and only when, the user asks you to review a diff, a pull request, or an artifact — code or documents, one or many — and actually says "review"; an explicit skill:bmad-review directive from another skill counts as that ask. A request to act on feedback from an earlier review is a change, not a review. Never invoke this uninvited, including on edits you just made.15012Bmad Specbmad-code-org/bmad-methodCondense any input — an idea, brief, PRD, transcript, or mixed notes — into a short spec: SPEC.md plus supporting files that downstream skills build from.

Use when writing or reviewing concurrent Go code, when choosing between channels and mutexes, when protecting a shared map or counter, or when a goroutine has no clear exit. Not for defensive coding unrelated to concurrency such as nil panics, slice aliasing, or numeric overflow (→ See `samber/cc-skills-golang@golang-safety` skill), and not for debugging a specific hung, crashing, or racing program after the fact (→ See `samber/cc-skills-golang@golang-troubleshooting` skill).1495Wecomcli Contactwecomteam/wecom-cli使用 wecom-cli 按姓名、拼音、英文名或别名搜索企业微信通讯录中的人员，并查询匹配人员的 userid、部门和职务。适用于查找联系人、区分同名人员、获取用户 userid，以及列出全部同名人员。1491
