Database schema validation, data integrity testing, migration testing, transaction isolation, and query performance. Use when testing data persistence, ensuring referential integrity, or validating database migrations.
Cloud design patterns for distributed systems architecture covering 42 industry-standard patterns across reliability, performance, messaging, security, and deployment categories. Use when designing, reviewing, or implementing distributed system architectures.
Establish build performance baselines and apply systematic optimization techniques. Only activate in MSBuild/.NET build context. Use when diagnosing slow builds, establishing before/after measurements, or applying advanced optimization strategies like MSBuild Server, static graph builds, artifacts output, and dependency graph trimming. Start here before diving into specific optimizations from build-perf-diagnostics, incremental-build, or build-parallelism skills. DO NOT use for non-MSBuild build systems.
Use this skill when designing database schemas, optimizing queries, creating indexes, planning migrations, or choosing between database technologies. Triggers on schema design, normalization, indexing strategies, query optimization, EXPLAIN plans, migrations, partitioning, replication, connection pooling, and any task requiring database architecture or performance decisions.
Build and operate modern Node.js applications with strong architecture, dependency hygiene, performance, resilience, observability, and security controls. Use when designing project layout, runtime/module strategy, testing and CI, release workflows, and production operations.
Analyze wallet portfolios on supported blockchains: view token holdings with current values, track transaction activity and history, check PnL (profit and loss) statistics over different time windows, and query total wallet net worth. Also supports querying the authenticated user's own LiberFi TEE wallet portfolio without needing to provide a wallet address — use the `me` commands when the user wants to check their own LiberFi account's holdings, activity, stats, or net worth. Trigger words: wallet, portfolio, holdings, my tokens, my coins, my balance, what do I hold, what tokens do I have, wallet balance, wallet holdings, wallet activity, transaction history, recent transactions, transfers, swaps, trade history, wallet stats, PnL, profit and loss, profit, loss, gains, returns, performance, how much did I make, how much did I lose, win rate, net worth, total value, portfolio value, total balance, how much is my wallet, wallet overview, wallet summary, wallet analysis, check wallet, view wallet, my portfolio, account balance, my LiberFi wallet, my TEE wallet, my account portfolio, check my account, my holdings without address. Chinese: 钱包, 持仓, 我的代币, 我持有什么, 余额, 钱包余额, 交易记录, 交易历史, 最近交易, 转账记录, 钱包统计, 盈亏, 利润, 亏损, 收益, 收益率, 胜率, 净值, 总价值, 钱包总价值, 钱包概览, 钱包分析, 查看钱包, 我的LiberFi钱包, 我的TEE钱包, 我的账户持仓, 不知道地址查我的钱包. CRITICAL: Always use `--json` flag for structured output. CRITICAL: Public `wallet` commands require both chain and wallet address — always ask the user for these if not provided. CRITICAL: `me` commands do NOT require a wallet address — they use the authenticated user's TEE wallet automatically. They DO require authentication (run `lfi status` first, then `lfi login key` if needed). Do NOT use this skill for: - Token search, info, security audit, K-line → use liberfi-token - Trending tokens or new token rankings → use liberfi-market - Swap quotes, trade execution, or transaction broadcast → use liberfi-swap - Token holder analysis (for a specific token) → use liberfi-token Do NOT activate on vague inputs like "wallet" alone without a wallet address or clear intent to check portfolio data.
Guide for implementing the Syncfusion WinUI Shimmer control to display loading placeholders and skeleton screens. Use this skill when implementing shimmer effects, skeleton screens, content loading animations, or loading placeholders during data fetching in WinUI applications. Essential for enhancing perceived performance during async operations, list loading, profile loading, article loading, or any content loading scenario requiring visual feedback.

JVM performance profiling with Java Flight Recorder (JFR), jcmd, and GC analysis. Use for identifying bottlenecks and memory issues. USE WHEN: user mentions "Java profiling", "JFR", "JVM performance", asks about "Java Flight Recorder", "jcmd", "heap dump", "GC tuning", "thread dump", "Java memory leak" DO NOT USE FOR: Node.js/Python profiling - use respective skills instead
Executes optimization hypotheses with keep/discard testing loop. Use when applying validated performance improvements.
