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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds genuinely useful context beyond them: the data comes from a public RSS feed and contains brief teaser summaries plus metadata rather than full article text, which tells the agent to expect truncated content.

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?

One sentence, zero filler, with the resource and scope front-loaded. Every clause (source, content shape, metadata) earns its place.

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 zero parameters, an existing output schema, and annotations covering the read-only/open-world profile, the description covers what an agent needs to call it. The only real gap is not routing the agent between this and the alcom_headlines/alcom_sections siblings.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. Nothing in the description misrepresents the parameterless interface.

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?

Names a specific verb (returns), resource (current AL.com News stories) and source (public RSS feed), so the agent knows exactly what it fetches. It does not, however, distinguish itself from the sibling alcom_headlines or alcom_sections, which an agent must infer from the naming pattern alone.

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 when-to-use guidance, no named alternatives, and no conditions under which this beats alcom_headlines or alcom_sections. The 'current' wording faintly implies recency, but the agent is left to guess the division of labour among the three alcom tools.

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