get_currency_feed

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

No annotations are present, so the description bears full responsibility. It only says 'chronological news feed' without disclosing important traits like pagination, time range, sorting, max results, or data source. Limited insight beyond basic functionality.

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 concise sentence that gets to the point. No wasted words, but it could include more detail without losing conciseness.

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?

With no output schema and minimal description, the tool is incomplete. The feed's content type, ordering, and constraints (e.g., how far back it goes) are missing. For a 2-parameter tool, this is insufficient for effective invocation.

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%, and the description does not mention the 'symbol' or 'limit' parameters. It adds no meaning beyond the raw schema, failing to explain what the symbol should be or how limit affects results.

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 it's a chronological news feed for a single currency, which indicates the main verb and resource. However, it doesn't explicitly differentiate from siblings like search_news or get_unified_feed, lacking explicit scope or type detail.

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?

No usage context provided. The description does not indicate when to use this tool over alternatives like search_news or get_recent_stories. Absence of when/when-not or prerequisite conditions.

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