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

53%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a concise, well-organized overview with strong MegaETH-specific directives, but it lacks executable code and validation checkpoints, and its progressive-disclosure references point to files that do not exist in the bundle.

Suggestions

Ship the nine referenced files (references/wallet-operations.md, frontend-patterns.md, rpc-methods.md, smart-contracts.md, storage-optimization.md, gas-model.md, testing.md, security.md, resources.md) so the progressive-disclosure links resolve — or inline the essential parts and drop the dead links.

Add at least one copy-paste executable example per common task (e.g., a complete eth_sendRawTransactionSync request or a WebSocket miniBlocks subscription snippet) to move actionability from directive to runnable.

Insert explicit validation/feedback steps into the operating procedure for destructive/batch operations — e.g., 'after signing, confirm the receipt before reporting success; on revert, re-estimate gas via remote eth_estimateGas'.

Dimension	Reasoning	Score
Conciseness	Mostly lean bullet points with no padding or teaching of known concepts (chain IDs, gas values, method names); the opening 'What this Skill is for' bullet list slightly overlaps the description and could be trimmed.	4 / 5
Actionability	Gives concrete, domain-specific guidance (chain IDs, 0.001 gwei base fee, eth_sendRawTransactionSync, 30s keepalive) but provides no copy-paste executable code or commands, so it reads as directive hints rather than runnable instruction.	3 / 5
Workflow Clarity	A clear four-step operating procedure exists (classify layer → pick patterns → implement with correctness → deliverables), but there are no validation/verification checkpoints for destructive/batch operations (transactions, storage writes), which caps this score at 3.	3 / 5
Progressive Disclosure	References are well-signaled and one level deep, but all nine referenced files (wallet-operations.md, frontend-patterns.md, etc.) are missing from the bundle — navigation is broken, so structure is ineffective.	2 / 5

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description that clearly states both what the skill covers and when to use it, with a well-defined MegaETH niche and minimal conflict risk. The only mild gap is trigger-term naturalness, which leans technical over colloquial.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete capabilities — wallet operations, token swaps (Kyber), eth_sendRawTransactionSync (EIP-7966), JSON-RPC batching, mini-block subscriptions, Solady RedBlackTreeLib storage, MegaEVM gas, WebSocket keepalive, bridging, and mega-evme debugging — giving comprehensive coverage.	5 / 5
Completeness	Explicitly answers 'what' with a concrete coverage list and 'when' via an explicit 'Use when building on MegaETH, managing wallets, sending transactions, or deploying contracts' clause with concrete triggers.	5 / 5
Trigger Term Quality	Natural trigger phrases appear ('building on MegaETH, managing wallets, sending transactions, or deploying contracts'), but the bulk is technical jargon (EIP-7966, RedBlackTreeLib) with few synonyms or user-facing variations, leaving a few common terms missing.	4 / 5
Distinctiveness Conflict Risk	Clearly scoped to a niche (MegaETH development) with distinctive, chain-specific triggers, making overlap with other skills minimal.	5 / 5
	Total	19 / 20 Passed
