Use this skill when a task requires reading, creating, splitting, merging, or otherwise manipulating PDF files.

Use when creating, running, debugging, or documenting skill-optimizer workbench evals; working with agent skill cases, suites, graders, traces, Docker workspaces, OpenRouter model matrices, or the skill-optimizer SDK/CLI.

Discover services on the Fast Marketplace, choose the right endpoint, follow Community/direct or Verified/escrow payment flows, use fixed-price x402, variable top-up, or prepaid-credit routes with a funded local wallet, handle async job retrieval, onboard providers, manage draft services, rotate provider runtime keys, review marketplace demand intake, and submit or review marketplace supply. Use this when a user wants to browse or call APIs exposed through marketplace.fast.xyz or api.marketplace.fast.xyz, or manage marketplace supply from the provider/admin surfaces. Route direct FAST SDK, AllSet bridge, hosted ramp, or generic x402 package work outside the marketplace to the main FAST skill instead.

Use when a Fast operator wants to run or schedule an external_registry provider test or monitoring run for the Fast agents marketplace, record results in the testing ledger, inspect failures, or verify the weekly marketplace API monitoring job from a local Codex workspace.

Hand off a Fast account's signing key from the user's wallet to your agent runtime using fast-cli's `authorize` commands. Use when the user wants to authorize you to sign on their behalf for a Fast account.

fast CLI for managing Fast network accounts, sending tokens, funding via bridge or fiat, and paying x402-protected APIs. Use when the user wants to run fast commands, create accounts, check balances, send USDC, or interact with the Fast network from the terminal.

x402 HTTP Payment Protocol SDK. Use when the user wants to pay for 402-protected content, protect API routes with payments, or run a facilitator service. Covers EVM (EIP-3009) and Fast payment flows, auto-bridging, and multi-network support.

Interact with the FastSet network — a high-performance settlement layer. Query accounts, submit transactions, transfer and mint tokens via the JSON-RPC proxy API. Supports Ed25519 wallet operations.

Router skill for the FAST ecosystem. Use when the user asks about FAST, fastUSDC, AllSet, @fastxyz/sdk, @fastxyz/allset-sdk, @fastxyz/x402-client, @fastxyz/x402-server, or @fastxyz/x402-facilitator; wants Fast balances, Fast transfers, Fast to EVM or EVM to Fast bridging, needs to top up Fast-side USDC via the hosted ramp link on `https://ramp.fast.xyz`, or wants to pay for or protect an API with FAST x402 packages. Do not use for generic EVM wallets, generic bridging, unrelated HTTP 402 questions, or non-FAST payment stacks.

AllSet SDK for bridging tokens between Fast network and EVM chains. Use sendToFast for deposits (EVM → Fast), sendToExternal for withdrawals (Fast → EVM), executeIntent for custom operations.
