crypto_articles_search_by_keywords

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

With no annotations, the description must carry the full behavioral disclosure. It mentions sorting (newest to oldest) and a fixed 24-hour window, but fails to mention pagination, response formats, or the configurable timeframe. The 'last 24 hours' statement is also inconsistent with the time_frame parameter, reducing transparency.

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 only two sentences but contains redundancy: 'can be filtered using keywords' and 'Specify keywords in the query parameters to refine the search' overlap. It is concise but not free of waste and includes an inaccurate fixed-time statement.

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 description is insufficient for a 5-parameter tool with no output schema and no annotations. It omits pagination behavior, format options, and timeframe flexibility. The parameter descriptions in the schema compensate partially, but the narrative leaves gaps for an agent to correctly set expectations.

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 baseline is 3. The description adds minimal value beyond reiterating keyword filtering; it does not elaborate on page, limit, format, or time_frame. The schema already provides adequate parameter explanations.

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 the tool retrieves crypto-related articles and filters by keywords, but it does not distinguish this tool from siblings like latest_news_search_by_keyword or crypto_articles. It specifies a time scope of 'last 24 hours' which may be misleading given the time_frame parameter supports other ranges.

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 by stating 'Specify keywords in the query parameters to refine the search,' giving basic how-to guidance. However, it does not explain when to use this tool versus alternative search tools, nor does it mention the adjustable time_frame.

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