Azure Blob Storage JavaScript/TypeScript SDK (@azure/storage-blob) for blob operations. Use for uploading, downloading, listing, and managing blobs and containers.

API design principles and decision-making. REST vs GraphQL vs tRPC selection, response formats, versioning, pagination.

Find the type defects `tsc` is structurally unable to report — a green build is not evidence the types are correct. Covers the two classes: (1) hand-written types that restate an authoritative source and disagree with it, caught by substituting the derived type at a fixed commit and diffing `tsc` output; and (2) the standing blind spots in the language and config — unchecked array/record indexing, bivariant method parameters, covariant arrays, `any` absorption at untyped boundaries, precise s...

Query Sentry via MCP — error triage, tag distribution, volume estimation, replay retrieval

Redux selector authoring for MetaMask Mobile: named `select<Feature><Thing>` selectors in `app/selectors/`, `createSelector` / `createDeepEqualSelector` from reselect, leaf reads of `state.engine.backgroundState`, and `useSelector(selectX)` in UI. Use when adding or creating a selector, updating or refactoring an existing selector, moving inline `useSelector` derivation out of a component or hook, or answering questions about selectors, reselect, `createSelector`, `createDeepEqualSelector`, `...

A file's JS→TS migration cost is driven mostly by context fan-in (upstream types it must read to derive from) and fan-out (downstream files that import it and must be updated), not by its line count. Scope and sequence migration tickets by it.

Verify platform lifecycle events before assuming they cause application-level side effects

Diagnose browser extension errors — MV3 vs MV2, background/UI context, error tagging

Review PR diffs that add or modify `useEffect` for the systemic React effect antipatterns

Derive types from authoritative sources (indexed access, `typeof`, `ReturnType`/`Parameters`, `Pick`/`Omit`, `Infer<typeof struct>`) instead of hand-writing ad-hoc types that duplicate, run too wide or too narrow, and drift.

Handle `any` correctly — it is not a type but a directive that disables type checking. Substitute by position (assignee → `unknown`, assigned → `never`). Two narrow exceptions: a generic constraint, and a callback parameter caught in a bivariant position between two fixed, irresolvable function-type constraints — both declared with an inline eslint-disable. Also covers the `any` that is never written down: a precise signature fed `any` at every call site, which no lint rule and no compiler ch...

Bazaar (bazaar.playhunch.xyz): prediction markets anyone opens by tagging the bot, settled by the person who opened them, paid in USDC on Base. Trigger to make a market from a phrase or from the post being replied to ("market this", "make a market: will X happen by Friday?") and confirm its preview; to bet, quote or get odds on a Bazaar market (a bazaar.playhunch.xyz link, a Bazaar market id, the word "bazaar", or a reply in a Bazaar market's thread); to resolve or void a market you created, ...

下单前风险护栏：1) plan —— 按固定风险百分比计算仓位大小（资金/风险%/入场价/止损价 → 数量、名义值、保证金、强平距离估算与警告）；2) check —— 查 CEX 当前敞口（资产快照、 挂单、订单跟踪）。任何真实下单（现货买/合约开仓）之前必须先跑本技能。 触发词：仓位、该买多少、下单前检查、风控、position sizing、risk check。

加密新闻抓取 + 关键词情绪统计（零 Key）：中文快讯（PANews）+ 英文头条 （CoinDesk / Cointelegraph RSS）。命令：latest 拉最新新闻、coin 按币过滤、 sentiment 看多/看空比例统计。用户提到「新闻、情绪、舆论、news、sentiment、 市场在讨论什么」时使用；分析代币时可与 market-data 组合补上消息面。 触发词：新闻、快讯、情绪、舆论、利好利空、news、sentiment。

本地行情数据网关：K线收盘价（1d/1h/4h，最多 90+ 根）、资金费率、合约持仓量 OI、 大户多空比、爆仓流、恐惧贪婪指数、市场综述。分析任何代币（WLD/RAY/PEPE 等）时 必须优先用本技能取历史行情与衍生品数据 —— 走本机后端（自带 5 分钟缓存 + 代理池出口）， 不要直连币安 API（会被 15s 超时 / 输出截断卡住）。 触发词：分析代币、研报、走势、K线、资金费率、持仓量、OI、多空比、爆仓、恐惧贪婪、 klines、funding、open interest、fear greed。

Step-by-step guide for adding a new data source provider to the free-crypto-news platform. Covers the full lifecycle from API evaluation to adapter implementation, testing, and registration. Use when integrating a new market data, on-chain, social, or news source.

Use Deltr to scan the Binance USDS-M Futures vs PancakeSwap V3 (BNB Chain) basis and funding, size a delta-neutral hedge (long DEX spot, short perp), and route it through a deterministic zero-LLM risk gate via Deltr's MCP tools or CLI. Paper mode by default (no keys); Binance Futures testnet with keys; an opt-in LIVE mode that places real mainnet orders and a real on-chain leg signed by the Binance Agentic Wallet. Deltr never holds a private key.

Deploy a new DeXe DAO with the one-call `dexe_dao_create` composite. Use SIMPLE mode (symbol + totalSupply) and let the tool synthesize a coherent, governance- safe config — it previews the resolved config + a safety proof and only broadcasts on confirm. Covers the quorum turnout rule (quorum ≤ 0.8 × votable share) and the ≥50% floor, the implicit-treasury pattern, and the deploy gotchas. Use when the user says "create/deploy a DAO".

Scaffold a new MCP prompt template. Use when the user asks to add a prompt, create a reusable message template, or define a prompt for LLM interactions.

Audits mobile app security — Android (AndroidManifest.xml: exported components, allowBackup, debuggable, cleartext traffic, network security config; WebView misconfigurations; hardcoded keys), iOS (Info.plist ATS exceptions, secrets in UserDefaults, keychain accessibility), and React Native/Flutter storage pitfalls. Use when the project contains AndroidManifest.xml, Info.plist, or Kotlin/Java/Swift/Dart/RN code.

Detects injection vulnerabilities in code — SQL/NoSQL injection (including NoSQL operator injection), OS command injection, cross-site scripting (XSS), path traversal, SSRF, insecure deserialization, template injection (SSTI), XXE, prototype pollution, ReDoS, open redirect, and unsafe file upload handling. Covers Node/JS, Python, Java, Go, PHP, Ruby, C# with per-language grep patterns and context-review rules. Use when auditing input handling, query construction, file operations, subprocess c...
