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

Annotations already establish readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that only 'public metadata and body paragraphs' are returned, which is useful scope information, but it says nothing about paywall/auth limits, rate limits, or what happens with a non-canonical URL.

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?

A single front-loaded sentence with no filler. It could perhaps split purpose from input requirement, but nothing is wasted.

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?

An output schema exists, so return-value detail is not required, and the description covers purpose plus the input source. Still missing for a scrape-style single-item tool: paywall/access caveats and behavior on invalid or redirected URLs.

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% for the single url parameter, so the description must carry the meaning. It does add a real constraint — the URL must be a canonical article URL — which is more than the schema conveys, but it gives no format example or guidance on how to obtain one.

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?

States a specific verb-resource pair: retrieve one Bloomberg article's public metadata and body paragraphs. The scope (single article) is clear, though it never names or contrasts with the sibling bloomberg_headlines / bloomberg_news tools that also serve Bloomberg 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?

There is no explicit when-to-use guidance or routing to alternatives — the only hint is that a 'canonical article URL' is expected. An agent must infer that this tool is for fetching a specific article it already has a URL for, rather than for discovery or search.

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