get_article_content

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full behavioral burden. It does communicate the key behavior: the tool performs a network download and scraping operation rather than a local lookup. However, it does not disclose potential failure modes, rate limits, or the live-scraping implications beyond the basic verbs.

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 a single efficient sentence with no filler. The key distinguishing facts—download, scrape, parse, specific article, from URL—are all present and front-loaded.

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?

The tool has an output schema and fully documented parameters, so the description does not need to explain return values or parameter details. It adequately captures the tool's role, though it could be slightly stronger by adding an explicit alternative or exclusion, e.g., 'use get_news_by_keyword if you do not have a URL'.

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 100%, so the description does not need to re-explain parameters. It does align the 'url' parameter with the stated purpose, but adds no meaning beyond the schema for 'full_data' or 'summarize'.

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 uses specific verbs ('Download, scrape and parse') and a specific resource ('content of a specific news article from a given URL'). This clearly distinguishes it from sibling tools, which all return news lists, trends, or search results rather than article content.

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 intended use case is clearly implied: use this tool when you have a direct URL and need the parsed article content. It does not explicitly name alternatives or state when not to use it, but the URL-based scope is distinct enough from the siblings that an agent can infer the correct choice.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
