Gin Go web framework. Covers routing, middleware, binding, validation, and rendering. Use for fast, minimalist Go APIs. USE WHEN: user mentions "gin", "gin-gonic", "go web framework", "go rest api", asks about "gin middleware", "gin binding", "gin validation", "gin router", "fast go api", "gin context" DO NOT USE FOR: Echo projects - use `echo` instead, Fiber projects - use `fiber` instead, Chi projects - use `chi` instead, non-Go backends
Blockchain analytics via Dune REST API — execute DuneSQL queries against live on-chain data, discover decoded contract tables, and monitor credit usage. Use when the user asks about on-chain data, wallet activity, DEX trades, token transfers, smart contract events, or says "query Dune", "run a Dune query", or "search Dune datasets". Pairs with MoonPay to analyze wallets you create and fund.
Search Zhihu (知乎) using agent-browser with proper authentication handling. Use when user asks to "search zhihu", "知乎搜索", "在知乎上找", or any Zhihu-related search requests. Handles login requirements, session persistence, and common error cases like 40362 restrictions.
Design social media assets with Efecto — Instagram posts, carousels, stories, YouTube thumbnails, TikTok covers, Twitter/X images, LinkedIn slides, Pinterest pins, and Facebook graphics. Use when asked to "design a post", "create a carousel", "make a thumbnail", "design social media", or any social content task. Requires Efecto MCP server.
Use when you need to write or improve integration tests — including Testcontainers with @ServiceConnection, @DataJdbcTest persistence slices, TestRestTemplate or MockMvcTester for HTTP, data isolation, and container lifecycle management for Spring Boot 4.0.x. Part of the skills-for-java project
Facilitates conversational discovery to create Architectural Decision Records (ADRs) for functional requirements covering CLI, REST/HTTP APIs, or both. Use when the user wants to document command-line or HTTP service architecture, capture functional requirements, create ADRs for CLI or API projects, or design interfaces with documented decisions.

Use this skill whenever the user wants Claude to directly interact with their Obsidian vault — reading a note or daily note, writing or appending content, searching vault contents, counting or listing notes, managing tasks, moving or renaming files, finding orphaned notes or broken links. Without this skill, Claude has no way to access vault data or execute vault operations. Treat any request that implies "go into my vault and do X" as a trigger — the user is asking Claude to act, not to explain. Also trigger for vault automation, CLI scripting, or cron-based workflows involving Obsidian, managing sync history, querying Bases, restoring file versions via history, managing bookmarks, or running JavaScript against the Obsidian API. Skip for pure conceptual questions: how Obsidian's GUI works, navigating settings menus, theme or plugin installation via the UI, iCloud/third-party sync conflicts, general Dataview query syntax, keyboard shortcuts, or parsing vault files with external scripts — anything where the user needs an explanation rather than Claude performing a vault operation.
Use when the user needs API design, microservices architecture, event-driven systems, database integration, caching strategies, or backend observability. Triggers: REST/GraphQL API implementation, service architecture design, message queue setup, rate limiting, health checks, OpenTelemetry integration.
Guide the design and implementation of automated pre-trade compliance systems that validate orders before execution. Use when building a compliance rule engine for an RIA or broker-dealer, configuring hard blocks and soft blocks, maintaining restricted and watch lists including MNPI-driven restrictions, setting concentration limits at security/sector/issuer level, implementing position limits or short selling controls, enforcing wash sale detection or free-riding prevention or pattern day trader identification, applying client-specific ESG screens or legal constraints, designing compliance override workflows with authorization and documentation, backtesting compliance rules, or evaluating compliance check latency impact on execution quality.
Guide regulatory filing obligations and deadlines for investment advisers, broker-dealers, and large traders. Use when the user asks about Form PF filing thresholds, 13F institutional holdings reports, 13H large trader filings, Form ADV amendment timing, FOCUS report preparation, blue sheet requests, CAT reporting infrastructure, or FINRA short interest and TRACE reporting. Also trigger when users mention 'filing deadline calendar', 'do we need to file Form PF', 'crossed the $100M 13F threshold', 'annual updating amendment', 'CAT clock synchronization', 'how to respond to a blue sheet request', 'FOCUS report errors', or ask which regulatory filings a firm must make and when.
Analyze lending products including mortgages, HELOCs, and personal loans with amortization and comparison tools. Use when the user asks about mortgage comparison, fixed vs ARM rates, loan qualification, amortization schedules, extra payments, or buying points. Also trigger when users mention 'monthly payment calculation', '15-year vs 30-year mortgage', 'PMI', 'APR vs interest rate', 'HELOC', 'home equity', 'should I buy down the rate', 'biweekly payments', or ask how much house they can afford.
Guide the design and implementation of order lifecycle management in trading systems. Use when building an order state machine for an OMS or EMS, implementing or debugging FIX protocol connectivity to exchanges, handling cancel/replace race conditions, defining pre-submission validation rules (buying power, position limits, restricted lists), selecting order types and time-in-force instructions, designing multi-leg or OCO or bracket orders, building CAT-compliant audit trails, troubleshooting order rejections or unexpected state transitions, hardening an OMS against edge cases, or implementing order persistence and recovery for failover. Also covers FIX message flows, ClOrdID chaining, and partial fill aggregation.
