Discovery
50%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
The description excels at specificity and distinctiveness by clearly naming the technology (Coinbase OnchainKit) and concrete capabilities (wallets, swaps, NFTs, payments). However, it critically lacks explicit trigger guidance ('Use when...') which significantly impacts its usefulness for skill selection, and could benefit from more natural user-facing keywords like 'crypto' or 'web3'.
Suggestions
Add a 'Use when...' clause specifying triggers like 'Use when building crypto/web3 React apps, integrating Coinbase wallets, or implementing token swaps and NFT functionality'
Include common user-facing terms like 'crypto', 'web3', 'blockchain', 'cryptocurrency wallet', 'token' that users would naturally say when needing this skill
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'wallets, swaps, NFTs, payments' and specifies the technology stack 'Coinbase's OnchainKit React components' for building 'onchain apps'. | 3 / 3 |
Completeness | Describes what the skill does (build onchain apps with specific components) but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. | 1 / 3 |
Trigger Term Quality | Includes relevant keywords like 'OnchainKit', 'wallets', 'swaps', 'NFTs', 'payments', 'Coinbase', and 'React components', but missing common variations users might say like 'crypto', 'blockchain', 'web3', 'token swap', or 'cryptocurrency'. | 2 / 3 |
Distinctiveness Conflict Risk | Very specific niche targeting Coinbase's OnchainKit specifically - unlikely to conflict with generic React skills or other blockchain frameworks due to the explicit 'OnchainKit' and 'Coinbase' identifiers. | 3 / 3 |
Total | 9 / 12 Passed |
Implementation
87%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 provides actionable guidance for building onchain apps with OnchainKit. The code examples are executable and the command structure is clear. The main weakness is the lack of validation steps or troubleshooting guidance for configuration and transaction operations.
Suggestions
Add a validation step after configuration (e.g., 'Verify API key: run npm run dev and check console for connection success')
Include basic error handling or troubleshooting for common issues like invalid API keys or failed wallet connections
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient, providing only essential information without explaining basic concepts Claude already knows. Every section serves a clear purpose with no padding or unnecessary context. | 3 / 3 |
Actionability | Provides fully executable code snippets for all core components, copy-paste ready bash commands for setup, and concrete configuration examples. The TSX examples are complete and immediately usable. | 3 / 3 |
Workflow Clarity | While the Quick Start section provides clear setup steps, there are no validation checkpoints or error handling guidance. For a skill involving blockchain transactions and API configuration, missing verification steps (e.g., confirming API key validity, testing wallet connection) is a gap. | 2 / 3 |
Progressive Disclosure | Well-organized with clear sections progressing from overview to commands to components to setup. External documentation is clearly signaled with direct links, and the /onchainkit docs commands provide one-level-deep navigation to detailed materials. | 3 / 3 |
Total | 11 / 12 Passed |
Validation
90%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
