Discovery
40%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 identifies a clear and distinctive niche (QR Coin auctions on Base), which minimizes conflict risk. However, it lacks an explicit 'Use when...' clause and could benefit from listing more concrete actions and natural trigger terms to help Claude reliably select this skill.
Suggestions
Add an explicit 'Use when...' clause, e.g., 'Use when the user asks about QR Coin, bidding on QR code auctions, or displaying URLs on QR codes on the Base blockchain.'
List more specific actions such as 'place bids, check auction status, view current QR code displays, withdraw bids' to improve specificity.
Include natural keyword variations users might say, such as 'Base chain', 'QR code NFT', 'auction bid', or 'onchain QR code'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (QR Coin auctions on Base) and a couple of actions (bid, display URLs on QR codes), but doesn't list multiple concrete actions comprehensively—e.g., no mention of checking auction status, withdrawing bids, or viewing current displays. | 2 / 3 |
Completeness | It describes what the skill does (participate in QR Coin auctions, bid to display URLs) but has no explicit 'Use when...' clause or equivalent trigger guidance, which per the rubric caps completeness at 2, and the 'what' itself is also somewhat thin, placing this closer to 1. | 1 / 3 |
Trigger Term Quality | Includes some natural keywords like 'QR Coin', 'auctions', 'Base', 'bid', 'QR codes', and 'URLs', but misses common variations a user might say such as 'place a bid', 'blockchain auction', 'QR code NFT', or 'Base chain'. | 2 / 3 |
Distinctiveness Conflict Risk | The description targets a very specific niche—QR Coin auctions on Base blockchain—making it highly unlikely to conflict with other skills. The combination of 'QR Coin', 'auctions', and 'Base' is distinctive. | 3 / 3 |

Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a concise, well-structured skill that clearly communicates the QR Coin auction concept and available commands. Its main weakness is the gap between listing commands and providing truly actionable guidance—there's no underlying implementation shown, and the bidding workflow lacks validation checkpoints (e.g., confirming approval succeeded before bidding, verifying transaction confirmation).
Suggestions
Add a step-by-step bidding workflow with explicit validation: check balance → approve USDC → verify approval → place bid → confirm transaction hash
Include executable code or script references showing how the /qr commands interact with the contract (e.g., ethers.js snippets or a reference to the CLI tool being used)
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Very lean and efficient. No unnecessary explanations of blockchain concepts, USDC, or how auctions work in general. Every line provides specific, useful information. | 3 / 3 |
Actionability | Commands are clearly listed with syntax, but there's no executable code showing how these commands are implemented—no contract ABI snippets, no actual transaction code, no script to run. The '/qr' commands imply a CLI tool but don't show how it's built or invoked beyond the command syntax. | 2 / 3 |
Workflow Clarity | The 'How It Works' section provides a reasonable overview of the auction flow, and commands are categorized. However, there's no explicit workflow for the bidding process (e.g., check status → approve USDC → place bid → verify), and no validation steps for confirming transactions succeeded or handling failures. | 2 / 3 |
Progressive Disclosure | For a simple, focused skill under 50 lines, the content is well-organized with clear sections (Contracts, How It Works, Commands, Examples, Setup). No need for external references given the scope. | 3 / 3 |
