double-check-perf-tests
by ClickHouse
Locally reproduce ClickHouse CI performance comparison results for a given commit. Fetches the perf CI report, identifies queries categorized as "Changes in Performance", downloads both the patched and reference binaries from S3 (matching the current machine architecture), and re-runs only those queries via tests/performance/scripts/perf.py to verify whether each regression/improvement is real. Use this whenever the user wants to "double-check", "reproduce", "verify locally", or "re-run" a perf check result — even if they don't name the skill.

ccxt-mcp
by ccxt
Official CCXT MCP (Model Context Protocol) server — connect an AI agent to 100+ cryptocurrency exchanges and prediction markets for market data, balances, and opt-in trading. Covers installing the server in Claude Desktop/Code, Cursor, VS Code and other MCP hosts; configuring named accounts and API keys (kept local, never seen by the model); the capability tiers and safety rails; sandbox/testnet trading; and how to drive the tools. Use when the user wants an agent to fetch prices/order books/candles, check balances/orders/positions, place or cancel orders, or explore prediction markets across exchanges.
nx-import

review-pr
by nrwl
Deep code review of a single open PR in nrwl/nx. Checks the PR out only inside an isolated sandbox, then runs four fixed reviewers: implementation (correctness, errors, types, performance), verification (tests, ticket grounding, comments, and docs), approach, and security. A reproduce-verifier executes a runnable repro only when verification identifies one. The skill saves a GitHub-flavored draft to ~/.nx-pr-reviews/<NUMBER>.md and never posts it. Claude reads/executes PR code only through the sandbox CLI; credentials never enter the sandbox.
