megaeth-developer
End-to-end MegaETH development playbook (Feb 2026). Covers wallet operations, token swaps (Kyber Network), eth_sendRawTransactionSync (EIP-7966) for instant receipts, JSON-RPC batching, real-time mini-block subscriptions, storage-aware contract patterns (Solady RedBlackTreeLib), MegaEVM gas model, WebSocket keepalive, bridging from Ethereum, and debugging with mega-evme. Use when building on MegaETH, managing wallets, sending transactions, or deploying contracts.

Quality
Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is an excellent skill description that is highly specific, comprehensive, and distinctive. It lists numerous concrete capabilities with specific technology references, includes a clear 'Use when' clause with natural trigger terms, and is clearly scoped to the MegaETH ecosystem, minimizing conflict risk with other blockchain-related skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists numerous specific concrete actions and technologies: wallet operations, token swaps (Kyber Network), eth_sendRawTransactionSync (EIP-7966), JSON-RPC batching, mini-block subscriptions, storage-aware contract patterns (Solady RedBlackTreeLib), MegaEVM gas model, WebSocket keepalive, bridging from Ethereum, and debugging with mega-evme. | 3 / 3 |
Completeness | Clearly answers both 'what' (comprehensive list of capabilities from wallet ops to debugging) and 'when' with an explicit 'Use when building on MegaETH, managing wallets, sending transactions, or deploying contracts' clause. | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'MegaETH', 'wallet', 'token swaps', 'transactions', 'deploying contracts', 'bridging from Ethereum', 'JSON-RPC', 'WebSocket'. These cover a wide range of terms a developer building on MegaETH would naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive due to the MegaETH-specific focus, referencing unique technologies like eth_sendRawTransactionSync (EIP-7966), MegaEVM gas model, mega-evme debugger, and Solady RedBlackTreeLib. Unlikely to conflict with general Ethereum or other blockchain skills. | 3 / 3 |

Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured skill that excels at conciseness and progressive disclosure, providing MegaETH-specific knowledge efficiently with clear pointers to detailed sub-files. Its main weaknesses are the lack of executable code examples for key operations (the detailed files may contain these, but the main skill should have at least a quick-start snippet) and missing validation checkpoints in the workflow for potentially destructive operations like transaction submission and contract deployment.
Suggestions
Add a 'Quick start' section with at least one executable code snippet showing the most common operation (e.g., sending a transaction with eth_sendRawTransactionSync using ethers.js or viem)
Add explicit validation/verification steps to the operating procedure, such as verifying transaction receipts, checking contract deployment success, and validating gas estimates before submission
Include a concrete WebSocket keepalive code example since the 30-second ping requirement is a MegaETH-specific detail that benefits from a copy-paste ready implementation
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient. It avoids explaining basic concepts (what Ethereum is, how RPCs work, etc.) and focuses on MegaETH-specific knowledge that Claude wouldn't already know. Every section delivers novel, domain-specific information. The table format for chain config and the opinionated defaults are well-compressed. | 3 / 3 |
Actionability | The skill provides specific configuration values (chain IDs, gas fees, keepalive intervals) and clear directives, but lacks executable code examples. There are no copy-paste ready code snippets for key operations like sending a transaction with eth_sendRawTransactionSync, setting up WebSocket keepalive, or using Multicall. The guidance is concrete but not fully executable. | 2 / 3 |
Workflow Clarity | The 4-step operating procedure provides a reasonable workflow (classify → pick patterns → implement → deliverables), but lacks validation checkpoints. For operations involving transaction submission, contract deployment, and storage-heavy operations, there are no explicit verify/validate steps or error recovery loops. | 2 / 3 |
Progressive Disclosure | Excellent progressive disclosure structure. The main file serves as a concise overview with opinionated defaults, and clearly signals 9 one-level-deep references for detailed topics. Each reference is well-labeled and covers a distinct concern. Navigation is straightforward. | 3 / 3 |
Total | 10 / 12 Passed |
