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

Content

64%

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, concise skill that effectively communicates MegaETH-specific knowledge Claude wouldn't already possess. Its main weakness is the lack of executable code examples for key operations (transaction sending, WebSocket setup, contract deployment), which limits actionability. The workflow section would benefit from explicit validation checkpoints, especially for transaction and deployment operations.

Suggestions

Add executable code snippets for the most common operations: sending a transaction with eth_sendRawTransactionSync, WebSocket keepalive setup, and Multicall batching — these are the core differentiators from standard EVM development.

Add validation checkpoints to the operating procedure, e.g., 'Verify transaction receipt fields match expected values' after sendRawTransactionSync, or 'Confirm contract deployment with eth_getCode' after deploying.

Include a concrete example of gas configuration showing hardcoded values (gasLimit, maxFeePerGas at 0.001 gwei) in a transaction object to make the gas guidance copy-paste ready.

DimensionReasoningScore

Conciseness

The content is lean and efficient. It avoids explaining basic concepts (what Ethereum is, how RPCs work, etc.), uses tables for configuration, and presents opinionated decisions as concise bullet points. Every section earns its place with MegaETH-specific knowledge Claude wouldn't already have.

3 / 3

Actionability

The skill provides specific configuration values (chain IDs, gas fees, RPC URLs) and clear decision rules, 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 performing a token swap. The guidance is concrete but not fully executable.

2 / 3

Workflow Clarity

The 4-step operating procedure provides a reasonable task classification and pattern selection workflow, but lacks validation checkpoints. For destructive operations like sending transactions or deploying contracts, there are no explicit verify/validate steps or error recovery loops. The deliverables section is helpful but the workflow itself is more of a decision tree than a validated sequence.

2 / 3

Progressive Disclosure

The skill has a well-organized overview with clearly signaled one-level-deep references to 9 supporting files. However, since no bundle files are provided, we cannot verify these references actually exist. The main SKILL.md itself is well-structured as an overview, but the referenced files are unverifiable, and some inline content (like the full chain configuration table and all 6 default stack decisions) could arguably be split out to keep the overview even leaner.

Description

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 technologies and standards, includes a clear 'Use when' clause with natural trigger terms, and targets a well-defined niche (MegaETH development) that minimizes conflict risk with other blockchain-related skills.

DimensionReasoningScore

Specificity

The description 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' (covers wallet operations, token swaps, instant receipts, JSON-RPC batching, etc.) 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 a developer would use: 'MegaETH', 'wallet', 'token swaps', 'transactions', 'deploying contracts', 'bridging', 'JSON-RPC', 'WebSocket', 'gas model'. These cover a wide range of terms a user building on MegaETH would naturally mention.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive due to the specific focus on MegaETH, a particular blockchain platform, with platform-specific features like eth_sendRawTransactionSync (EIP-7966), MegaEVM gas model, and mega-evme debugger. Unlikely to conflict with general Ethereum or other blockchain skills.
