Responsive HTML email template generation using MJML 4.x framework.

Also use when the user asks to compile MJML to HTML, work with or edit existing MJML templates, or troubleshoot email rendering issues across clients.

Operate a BKD kanban board over its REST API. Use when the user wants to manage BKD projects, issue execution workflows, cron jobs, or execution capacity through a reachable BKD server.

Use the LI.FI MCP server through UXC for cross-chain route discovery, bridge/DEX availability checks, token and chain lookup, gas/balance/allowance checks, quote generation, and transfer status tracking. Use when tasks involve planning or monitoring cross-chain swaps and bridges without signing or broadcasting transactions.
Build token swap functionality with Circle App Kit or standalone Swap Kit SDKs. App Kit (`@circle-fin/app-kit`) is an all-inclusive SDK covering swap, bridge, and send -- recommended for extensibility. Swap Kit (`@circle-fin/swap-kit`) is a standalone package for swap-only use cases. Both require a kit key and run server-side only. Swap is mainnet-only (no testnet support). Supports same-chain swaps. For cross-chain token movement, combine separate swap and bridge calls using App Kit (swap tokenA to USDC, bridge USDC, swap USDC to tokenB). Use when: swapping tokens, exchanging stablecoins, converting USDT to USDC, setting up swap adapters (Viem, Solana Kit, Circle Wallets), estimating swap rates, configuring slippage or stop limits, collecting custom swap fees, or combining swap and bridge for cross-chain token movement. Triggers on: swap tokens, token exchange, App Kit, Swap Kit, @circle-fin/app-kit, @circle-fin/swap-kit, USDT to USDC, swap USDC, swap stablecoin, estimateSwap, slippage, stop limit, kit key, swap fees.
Retargeting and remarketing strategy — website visitor retargeting, cart abandonment recovery, dynamic product ads, cross-channel retargeting, audience segmentation, frequency capping, attribution, pixel setup, in-app retargeting. Use when website visitors leave without converting, cart abandonment rates are too high, retargeting ads aren't profitable, you're unsure which retargeting platform to use, or past visitors never come back. Do NOT use for AdRoll-specific config (use /sales-adroll), Remerge-specific config (use /sales-remerge), email marketing (use /sales-email-marketing), B2B account-based advertising (use /sales-b2b-advertising), or general paid ads strategy (use /paid-ads).
