Discovery
54%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 effectively identifies a specific niche (prediction market portfolio syncing) with excellent platform-specific trigger terms. However, it lacks explicit 'when to use' guidance and could benefit from listing additional concrete actions beyond just syncing positions.
Suggestions
Add a 'Use when...' clause with trigger terms like 'prediction markets', 'betting positions', 'market portfolio', or when users mention any of the three platforms
Expand the action list to include related capabilities such as 'view balances', 'track P&L', 'compare positions across platforms', or 'export holdings'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (prediction market portfolios) and one action (sync positions), but doesn't list multiple concrete actions like viewing, analyzing, exporting, or comparing positions. | 2 / 3 |
Completeness | Describes what it does (sync positions) 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 excellent natural keywords users would say: 'portfolio', 'positions', and the three specific platform names (Polymarket, Kalshi, Manifold) that users would naturally mention when needing this skill. | 3 / 3 |
Distinctiveness Conflict Risk | Very clear niche with distinct platform names (Polymarket, Kalshi, Manifold) that are unlikely to conflict with other skills; prediction market portfolio syncing is a specific domain. | 3 / 3 |
Total | 9 / 12 Passed |
Implementation
64%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill provides comprehensive, executable code for syncing portfolio positions across three prediction market platforms. Its main strengths are actionability and concrete implementations. However, it's verbose for a skill file, lacks error handling/validation workflows, and would benefit from better progressive disclosure by splitting platform-specific code into separate reference files.
Suggestions
Add explicit error handling and validation steps (e.g., 'If API returns 401, re-authenticate; if rate limited, wait and retry') to improve workflow clarity
Split platform-specific implementations into separate files (e.g., POLYMARKET.md, KALSHI.md, MANIFOLD.md) and keep SKILL.md as a concise overview with the unified sync function
Remove the introductory sentence and consolidate the Position dataclass definition to appear once at the top rather than implicitly requiring all prior functions
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient with executable code, but includes some unnecessary verbosity like the introductory sentence and could consolidate redundant patterns (e.g., multiple similar position-fetching functions with overlapping structure). | 2 / 3 |
Actionability | Provides fully executable Python code for all three platforms with concrete API endpoints, data structures, and copy-paste ready examples including environment variable usage and complete function implementations. | 3 / 3 |
Workflow Clarity | The skill presents individual platform sync methods and a unified sync function, but lacks explicit validation checkpoints or error handling guidance. No verification steps for confirming successful syncs or handling API failures. | 2 / 3 |
Progressive Disclosure | Content is organized by platform with clear sections, but the skill is quite long (~300 lines) and could benefit from splitting platform-specific implementations into separate files with SKILL.md serving as an overview with references. | 2 / 3 |
Total | 9 / 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.
