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 a strong skill description that clearly defines its blockchain/Web3 development domain with specific capabilities and explicit trigger guidance. It uses appropriate third-person voice, lists concrete actions, and includes natural keywords users would actually say. The 'Use PROACTIVELY for...' clause provides clear selection criteria.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions: 'Build production-ready Web3 applications, smart contracts, and decentralized systems' and 'Implements DeFi protocols, NFT platforms, DAOs, and enterprise blockchain integrations' - these are concrete, actionable capabilities.	3 / 3
Completeness	Clearly answers both what (build Web3 apps, smart contracts, DeFi protocols, NFT platforms, DAOs, enterprise integrations) AND when ('Use PROACTIVELY for smart contracts, Web3 apps, DeFi protocols, or blockchain infrastructure') with explicit trigger guidance.	3 / 3
Trigger Term Quality	Excellent coverage of natural terms users would say: 'smart contracts', 'Web3 apps', 'DeFi protocols', 'blockchain infrastructure', 'NFT platforms', 'DAOs'. These are terms users naturally use when requesting blockchain development help.	3 / 3
Distinctiveness Conflict Risk	Clear niche in blockchain/Web3 development with distinct triggers like 'smart contracts', 'DeFi', 'NFT', 'DAOs', 'Web3'. Unlikely to conflict with general coding skills due to specific blockchain terminology.	3 / 3

Implementation

22%

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

This skill functions as a navigation hub to sub-skills but fails to provide any actionable blockchain development guidance in the main file. It lacks executable code examples, concrete workflows, and specific technical instructions that would make it immediately useful. The content describes capabilities rather than demonstrating them.

Suggestions

Add a Quick Start section with executable Solidity code for a basic smart contract deployment workflow

Include a concrete multi-step workflow for a common task (e.g., deploy contract -> verify -> interact) with validation checkpoints

Replace generic instructions ('Apply relevant best practices') with specific blockchain commands or code patterns

Provide at least one complete, copy-paste ready example before directing to sub-skills

Dimension	Reasoning	Score
Conciseness	The content has some redundancy (repeating 'blockchain developer' in use/don't use sections, restating purpose twice) and includes generic instructions that don't add blockchain-specific value, but isn't excessively verbose.	2 / 3
Actionability	No concrete code examples, commands, or executable guidance provided. The content is entirely abstract ('Apply relevant best practices', 'Provide actionable steps') with no specific blockchain code, contract patterns, or implementation details.	1 / 3
Workflow Clarity	No clear workflow or sequence for any blockchain development task. The instructions are vague ('Clarify goals', 'validate outcomes') without specifying how to actually develop, test, or deploy smart contracts or Web3 applications.	1 / 3
Progressive Disclosure	References to 11 sub-skills and a resources file show good structure intent, but the main skill provides almost no substantive content itself—it's essentially just a table of contents with no quick-start guidance or concrete overview.	2 / 3
