Get a specific news item by its ID.
Returns the full free-tier details for a single news item including
headline, sentiment, categories, sources, and tweet URL.
Args:
id: The news item ID (returned in results from get_latest_news or search_news).
| Name | Required | Description | Default |
|---|---|---|---|
| id | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It mentions 'full free-tier details' and lists what is returned (headline, sentiment, categories, sources, tweet URL), which provides useful behavioral transparency. However, it does not mention whether the resource is read-only, any rate limits, or what happens if the ID is invalid.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and front-loaded with the core purpose. The additional detail about return fields and parameter source is relevant and efficient. However, the inclusion of the 'Args:' docstring is slightly redundant given the input schema, though it adds helpful context.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the low complexity (single parameter, no output schema, no annotations), the description provides sufficient context: what the tool does, what it returns, and where the ID comes from. It is complete enough for an agent to invoke correctly, though missing some behavioral details (error handling, rate limits).
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. The description explains the 'id' parameter's source (from get_latest_news or search_news results), which adds significant meaning beyond the schema's minimal type annotation. This gives the agent necessary context to supply a valid ID.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get a specific news item by its ID', which is a specific verb-resource combination. It distinguishes from siblings like 'get_latest_news' and 'search_news' by focusing on retrieving a single item by ID, which is unique among the sibling tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage context by noting the ID comes from get_latest_news or search_news, which provides guidance on when to use this tool. However, it lacks an explicit statement of when not to use it or mention of alternatives for other use cases.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Most tools have distinct purposes, but get_enriched_news lacks clear parameters, making it ambiguous whether it returns a specific item, the latest, or category-based news. This could cause confusion with get_latest_news or get_news_item.
All tool names follow a consistent 'get_<noun>' pattern, making the naming predictable and easy to interpret.
Seven tools is well-scoped for a crypto news API, covering essential operations without being too few or too many.
The tool set covers the core workflow: listing categories, fetching latest news, searching, getting details, recaps, and premium enrichments. No obvious gaps for a read-only news service.
