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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds behavioral context about category filtering and compact-mode support, but stops short of describing pagination behavior, result limits, or what fields come back — and 'compact=true 지원' is a bare feature flag that the schema has to explain.

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?

Three short Korean sentences with the core purpose front-loaded; no filler or repetition. The compact mention is terse enough to seem cryptic without the schema, which keeps this from a 5.

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 simple read-only list tool with rich annotations and fully documented parameters, the description is mostly adequate. Gaps: there is no output schema to define the return format and the description does not cover it, nor does it clarify page/pagination semantics or differentiate from get_active_notices/search_notices.

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 baseline is 3; the schema already documents page defaults, compact's return differences, and the full category list. The description adds modest value by stating category's filtering role and pointing to list_notice_categories, but nothing beyond that.

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?

The description opens with a specific verb+resource: '공지사항 최신 목록을 조회합니다' (retrieves the latest notice list), and adds the category-filtering scope. However, it never distinguishes itself from closely related siblings like get_active_notices, get_department_notices, or search_notices, so an agent must infer which notice-listing tool fits the task.

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?

It provides one useful routing pointer — use list_notice_categories to obtain valid category values — but gives no when-to-use versus when-not-to-use guidance relative to the four other notice tools. Usage context is implied ('최신' = latest) rather than stated as a selection rule.

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