Quality

Content

85%

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

The body is highly actionable and well-organized with clear setup and error handling. The main weakness is token inefficiency from repeating the full curl boilerplate for every endpoint.

Suggestions

Factor the shared curl invocation (base URL, auth header, content-type) into a single documented template and show only the differing JSON payload per endpoint.

Reconcile the '<details> curl equivalent' block, which uses a different base URL (api.orth.sh) and omits auth — clarify or remove it to avoid confusion.

Move the descriptive line 'Get current odds, prices, and market data...' out of the Setup section into the intro/When-to-Use area where it belongs.

DimensionReasoningScore

Conciseness

The body is mostly lean with no concept-explaining fluff, but the full curl boilerplate (headers, base URL, auth) is repeated verbatim across 7+ endpoints and 4 examples and could be factored into a shared snippet or variable.

2 / 3

Actionability

Every endpoint is given as a complete, copy-paste-ready curl command with real query params, plus a documented response field schema and worked user examples.

3 / 3

Workflow Clarity

For a simple read-only API skill the flow is unambiguous: load credentials (with a fallback login instruction), call the endpoint, then consult the documented error codes (400/401/429).

3 / 3

Progressive Disclosure

A self-contained single file (no bundle dirs exist) organized into clear, well-labeled sections (Setup, Usage, Response, Examples, Error Handling, Tips) with no nested references.

Description

57%

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 clearly names its niche and platforms but reads as a what-only statement. Adding an explicit 'Use when...' trigger clause and a couple more natural keywords would lift the weaker dimensions.

Suggestions

Add an explicit trigger clause, e.g. 'Use when the user asks about prediction market odds, Polymarket, Kalshi, or event probabilities.'

Broaden natural trigger terms to include 'betting markets', 'probability', and 'event odds'.

Mention a couple more concrete actions (e.g. searching markets, viewing activity) to raise specificity.

DimensionReasoningScore

Specificity

Names the domain (prediction markets, Polymarket, Kalshi) and two concrete actions ('odds', 'prices'), but stops short of the multiple distinct actions (e.g. search, activity, orders) shown in the body.

2 / 3

Completeness

It states what the skill does but has no 'Use when...' trigger clause, which caps completeness at 2 per the guidelines.

2 / 3

Trigger Term Quality

'prediction market odds', 'Polymarket', and 'Kalshi' are natural user terms, but common variations like 'betting markets', 'probability', or 'event odds' are absent.

2 / 3

Distinctiveness Conflict Risk

Naming two specific platforms (Polymarket, Kalshi) gives it a clear niche unlikely to conflict with other skills.
