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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds useful context that results come from a single public section RSS feed with brief summaries, but discloses nothing about rate limits, freshness, or pagination beyond that.

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; the resource and source come first and the parameter hint trails it. Efficient, though it packs the parameter guidance into an awkward semicolon clause.

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 values need not be described. For a one-parameter read tool the description is nearly sufficient, but the missing differentiation from alcom_news/alcom_sections and the incomplete section value list leave it just adequate.

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 there is no enum, so the schema offers nothing for 'section'. The description partly compensates by giving example values ('news, sports, or life'), which is genuine added value, but the list is clearly non-exhaustive and no format guidance is given.

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 ('Returns current AL.com headlines and brief summaries') and the source ('one public section RSS feed'). It does not explicitly distinguish itself from its siblings alcom_news and alcom_sections, so it falls short of a 5.

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 clause 'provide news, sports, or life' implies what to pass and by extension when the tool is appropriate, but it never says when to prefer this over alcom_news or alcom_sections, nor states any exclusions. Usage is only implied.

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