Install with your agent
Agent handoff
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
New install
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
Upgrade existing
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.

Overview
Builds a complete Uniswap V4 hook by delegating to the hook-builder agent. Handles the full development lifecycle: understanding requirements, determining hook flags, generating Solidity contracts, generating Foundry tests, mining a CREATE2 address with correct flag bits, and producing deployment scripts. Returns production-ready code artifacts written directly to the project.
When to Use
Activate when the user asks: "Build a V4 hook" "Create a limit order hook" "Build a dynamic fee hook" "Create a TWAMM hook" "Custom hook for V4" "Hook that charges higher fees during volatility" "Build a hook that distributes LP fees to stakers" "Create a hook with oracle integration"
Parameters
ParameterRequiredDefaultDescriptionbehaviorYes--Hook behavior description (e.g., "limit orders", "dynamic fees", "TWAMM", "oracle-based pricing")callbacksNoAuto-detectSpecific V4 callbacks if the user knows them (e.g., "beforeSwap, afterSwap")constraintsNo--Gas budget, security requirements, or specific design constraintschainNoethereumTarget chain for deployment (affects PoolManager address)
Workflow
Extract parameters from the user's request: identify the hook behavior, any explicitly mentioned callbacks, constraints, and target chain. Delegate to hook-builder: Invoke Task(subagent_type:hook-builder) with the full context. The hook-builder agent will: Understand the requirements and determine which callbacks are needed Map callbacks to hook flags and validate the flag combination Generate a Solidity contract extending BaseHook with proper NatSpec Generate comprehensive Foundry tests (unit, integration, edge cases, gas snapshots) Mine a CREATE2 salt that produces an address encoding the required flags Produce a deployment script with verification steps Present results to the user with a summary covering: Files written (contract path, test path, deployment script path) Hook architecture explanation (what it does, how state flows) Callbacks implemented and their flag bitmask Gas estimates per callback (from Foundry test output) Next steps for the developer (run tests, deploy to testnet, mainnet considerations)
Output Format
Present a summary followed by the generated files: V4 Hook Built: LimitOrderHook Contract: src/hooks/LimitOrderHook.sol (187 lines) Tests: test/hooks/LimitOrderHook.t.sol (12 tests) Deployment: script/DeployLimitOrderHook.s.sol Callbacks: beforeSwap, afterSwap Flags: 0x00C0 CREATE2: Salt mined, address verified Gas Estimates: beforeSwap: ~45,000 gas afterSwap: ~32,000 gas Total overhead per swap: ~77,000 gas Architecture: Orders are placed at specific ticks and stored in an on-chain order book. During beforeSwap, the hook checks for matching orders at the target tick. Matched orders are filled atomically within the same transaction. Next Steps: 1. Run tests: forge test --match-contract LimitOrderHookTest 2. Deploy to testnet: forge script script/DeployLimitOrderHook.s.sol --rpc-url sepolia 3. Verify on Etherscan: forge verify-contract <address> LimitOrderHook
Important Notes
This skill delegates entirely to the hook-builder agent -- it does not call MCP tools directly. The hook-builder generates production-quality Solidity code with reentrancy protection and access control. CREATE2 address mining ensures the deployed address encodes the correct hook flags in its leading bytes (required by V4 PoolManager). Foundry must be installed for test generation and compilation. If not found, the skill will provide installation instructions. Generated code uses Solidity ^0.8.26 and imports from @uniswap/v4-core and @uniswap/v4-periphery.
