Python testing patterns skill covering pytest, TDD methodology, fixtures, mocking, parametrization, and coverage requirements for robust test suites

Creates animation-rich HTML slide presentations from scratch or by converting PowerPoint files.

A skill from Binance Skills Hub that gives AI agents native access to crypto token information, enabling token searches and data queries across centralized and decentralized exchanges through natural language.

Browser automation via the `opencli` CLI — controls Chrome step-by-step while reusing existing login sessions (no passwords, no LLM API key). Enforces agent-friendly rules: use structured `state` with `[N]` indices instead of `screenshot`, chain commands with `&&`, prefer `network` to discover JSON APIs over DOM scraping, and never use `eval` to click or type.

Crypto market intelligence skill for `@emblemvault/agentwallet` that aggregates trending tokens, derivatives data, smart-money flows, and ETF flows from CoinGecko, Birdeye, CoinGlass, and Nansen via named tools (`getTrendingCoins`, `birdeyeTradeData`, `getCoinglassOpenInterestHistory`, `nansen_smart_money_flows`, etc.). Read-only — explicitly *not* supported: technical analysis indicators, social sentiment, DeFiLlama TVL, BTC dominance.

Retrieves current weather and forecasts for any location using free services, with multiple output formats and no API key required.

Implements comprehensive security best practices for Spring Boot services, covering authentication, authorization, input validation, and common vulnerability protection

A curated collection of awesome LLM applications with skills for building AI-powered apps, covering RAG, agents, and various use cases.

Memecoin discovery and risk-assessment skill driven by the `@emblemvault/agentwallet` CLI, covering Pump.fun/LaunchLab launches, Clanker (Base) and MemeJob (Hedera) discovery, Birdeye trade data, rugcheck risk scoring, and Nansen smart-money tracking across Solana, Base, and Hedera. Skill explicitly names the exact tool to call (e.g. `getPumpFunTokens`, `rugcheck`) for each scouting/risk task and lists what is *not* supported (social sentiment, exit strategies, charts).

A library of 155 production-ready development skills covering every aspect of modern software engineering from project setup to production deployment.

Django development patterns skill covering REST API design with DRF, ORM best practices, caching, signals, middleware, and production-grade project structure

Executes guided token swaps across Solana (`splBuyIntent`), Ethereum/Base/BSC/Polygon (per-chain `*SwapQuote`/`*Swap`), Hedera, and cross-chain via ChangeNow through the `@emblemvault/agentwallet` CLI. Enforces a balance → quote → user-confirmed execute → verify flow with safe-mode confirmation on every value-moving call.

DeFi yield research and liquid-staking entry skill for `@emblemvault/agentwallet`: research APYs/protocols with LLM knowledge plus Birdeye trending data, view existing LP/lending/staking/farming positions via `nansen_defi_portfolio`, and enter positions through token swaps on Solana/Ethereum/Base/BSC/Polygon/Hedera. Cannot directly add/remove LP, open CLMM positions, claim farming rewards, or rank live pool APYs — those still need DEX UIs.

Cross-chain portfolio tracker on `@emblemvault/agentwallet` that aggregates Solana, Ethereum, Base, BSC, Polygon, Hedera, and Bitcoin balances with USD values, plus conditional trade P&L (`getAllPositions`) and Nansen DeFi positions (`nansen_defi_portfolio`). Read-only — explicitly *not* supported: transaction history, tax exports, unrealized P&L on held tokens, 24h portfolio change, allocation %.

Classify and explain Momentic test-run failures using the `momentic_*` MCP tools — `momentic_get_run` and `momentic_list_runs` (always with `gitBranchName`) — to compare across runs, inspect screenshots/logs/network/video artifacts, and bucket failures into defined categories with reasoning.

Create and maintain Momentic browser E2E tests through the `momentic_*` MCP tool suite — natural-language locators, AI checks, and Playwright steps in Momentic's YAML schema. Enforces strict workflow: always call `momentic_get_initial_data` first, never edit YAML directly, never splice unvalidated steps, and always carry preview cache keys into splice.
