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

With no annotations, the description carries full behavioral disclosure burden, but it only says 'fetch latest feed' and 'category filter possible.' It does not disclose read-only nature, ordering behavior, default pagination, category matching semantics, or what the response contains.

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?

Two short Korean sentences are tightly packed: resource, action, and key capability. No filler or repetition.

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 read tool with no annotations and no output schema, the description is thin. An agent still does not know what a feed entry looks like, how categories are matched, or how pagination behaves.

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 100%, so the schema already documents page, limit, and category. The description adds only the category filtering concept, which is useful but not substantial enough to exceed the baseline 3.

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?

Description states a specific action ('가져옵니다' / fetch) on a specific resource ('제주돌담 최신 피드' / latest Jeju DolDam feed), with category filtering. This clearly distinguishes it from siblings like get_post (single post) and search_posts.

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 implies it is for browsing the latest feed with an optional category filter, but it does not explicitly state when to choose this over search_posts/search_property_listings or any exclusions. No alternative tools are named.

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