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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds useful context that only published magazine posts are returned and that each entry carries title, summary and URL, but says nothing about ordering, pagination behavior or result size.

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 tight sentence that front-loads the content categories and then the returned fields. No filler, though the parenthetical field list is the only structural aid in an otherwise unpunctuated string.

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?

For a no-required-parameter read-only list tool with no output schema, the description does state what comes back, which is the main thing an agent needs. It remains thin on the only parameter and on result ordering/limits, which is a genuine but minor gap at this complexity.

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 single `limit` parameter has 0% schema description coverage and is never mentioned in the description — no default, cap, or retry/paging semantics are explained. The schema constraints (min 1, max 30, default 10) carry all the meaning, so the description fails to compensate for the coverage gap.

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-resource pair (list published magazine guides) and enumerates the returned fields (제목·요약·주소), which lets an agent distinguish it from the product/store siblings. It stops short of explicitly contrasting itself with any sibling, so it lands at 4 rather than 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 description states what content exists but gives no when-to-use signal, no condition distinguishing it from search_products or list_categories, and no prerequisites. An agent must infer that this is the browsing endpoint for editorial content.

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