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.

Validation for skill structure
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 comprehensively covers MegaETH development capabilities with specific actions, tools, and protocols. It includes a clear 'Use when...' clause with natural trigger terms and is highly distinctive due to MegaETH-specific terminology. The description uses proper third-person voice throughout.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: wallet operations, token swaps (Kyber Network), eth_sendRawTransactionSync, JSON-RPC batching, mini-block subscriptions, storage-aware contract patterns, bridging, and debugging with mega-evme. | 3 / 3 |
Completeness | Clearly answers both what (comprehensive list of MegaETH development capabilities) AND when with explicit 'Use when...' clause covering building on MegaETH, managing wallets, sending transactions, or deploying contracts. | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'MegaETH', 'wallet', 'token swaps', 'transactions', 'deploying contracts', 'bridging from Ethereum', 'WebSocket', plus specific technical terms like 'EIP-7966' and 'Solady RedBlackTreeLib' for advanced users. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with clear niche targeting MegaETH specifically, including unique identifiers like 'MegaEVM', 'mega-evme', and 'EIP-7966'. Unlikely to conflict with general Ethereum or other blockchain skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
85%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 efficiently communicates MegaETH-specific knowledge without redundancy. The progressive disclosure is excellent with clear navigation to detailed topics. The main weakness is the lack of executable code examples - the guidance is specific but descriptive rather than copy-paste ready.
Suggestions
Add executable code snippets for key operations like eth_sendRawTransactionSync usage and WebSocket keepalive implementation
Include a concrete example of Multicall aggregate3 batching with actual contract addresses or pseudocode that's closer to executable
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is lean and efficient, presenting MegaETH-specific information in tables and bullet points without explaining basic concepts Claude already knows. Every section adds unique value about this specific chain's quirks. | 3 / 3 |
Actionability | Provides specific configuration values (chain IDs, gas fees, RPC URLs) and clear guidance, but lacks executable code examples. The patterns are described rather than demonstrated with copy-paste ready snippets. | 2 / 3 |
Workflow Clarity | Clear 4-step operating procedure with explicit task classification, pattern selection, implementation considerations, and deliverable expectations. The workflow is well-sequenced for the multi-faceted nature of MegaETH development. | 3 / 3 |
Progressive Disclosure | Excellent structure with a concise overview and well-signaled one-level-deep references to 9 specialized files. Content is appropriately split between quick-reference decisions and detailed implementation guides. | 3 / 3 |
Total | 11 / 12 Passed |
