Tester automation for Yunxiao (Projex): accept and start 【Test】 tasks and advance requirements from pending test → testing; record plans, test case execution, reports, and test deployment evidence from the verifiable test evidence checklist; after diagnosis and duplicate checking, create defects in one click; for both standalone defect creation and defect creation from test cases, the verifier is mandatorily set to the currently logged-in tester and read back, (this-cycle deliverables bind the development owner / non-this-cycle ones use a self-designated owner); pull the list of fixed | not-to-be-fixed pending verification; batch close fixed ones, reopen reproduced defects, and merge closed ones into the current iteration only after each Bug has independent retest-pass evidence; the normal completion path keeps the original evidence gate, and "complete testing" may also enter the audit release branch when the tester explicitly gives "manual confirmation passed = yes"; mark the current 【Test】 task as completed and advance the requirement to test complete, and mark it as an unofficial release candidate, only when all non-cancelled development tasks uniquely map to test tasks and sibling test tasks are complete. Use when the user says YunxiaoQA, test task, pull test tasks, create defect, reopen, batch close, merge into iteration, start testing, record test evidence, complete testing, manual confirmation passed, close the loop on test tasks, receive release backflow, verify release backflow, hand over release. Also call proactively when the user does not write the Skill name or standard phrase but natural language clearly expresses viewing their own test tasks, starting/continuing/completing formal testing, recording evidence, filing a Bug, retest-close, or reopening; first uniquely locate the 【Test】 task or Bug via the official CLI, then normalize to existing commands. With zero or multiple candidates, return read-only without guessing the number from the title. Do not trigger when it is only about running local code tests, developer self-testing, or fixing code with no Yunxiao test task context. Tester role only; does not create 【Development】/does not create iterations/does not fix already-fixed items on behalf of developers. For any write to Yunxiao, first Plan for confirmation, then apply in one go; do not align with yunxiao-requirement-lifecycle.
Create web interface designs that match Chinese aesthetic sensibilities. Use when the user needs to design web pages, components, pages, or app interfaces. Focuses on a clean, refined, harmonious design style and generates front-end code that can be used directly. Not for reviewing existing UI code, optimizing existing component implementations, or generating pure back-end code or non-web UI.
Trade on 1024 Exchange via its public HTTP API — perpetuals, prediction markets, and alpha (trading opportunities mined by AI and data, published so anyone can execute them in two calls). Onboarding, HMAC-signed orders, positions, balances, treasury and withdrawals. Use when the user asks to trade, quote, monitor, or automate anything on 1024 / 1024ex.com; when they ask what is worth trading, want to act on someone's published alpha or action list, or want to publish their own; or when they want to connect or log in to their 1024 account.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
