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

With no annotations provided, the description carries the transparency burden but only partially. It adds useful details: 'public' (no auth), 'by follower count' (ordering), and 'max 20' (result cap). However, it does not disclose sort direction, pagination continuation semantics, response format, or rate limit behavior.

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?

The description is a single, focused sentence that front-loads the tool's purpose and constraints with no filler. Every phrase adds value: 'public', 'by follower count', and 'max 20'.

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?

The tool has moderate complexity (pagination via page/cursor/per_page) and no output schema, so the description should ideally clarify the return shape or pagination behavior. It states the core purpose and constraints but omits what the response contains and how to continue pagination beyond the schema's cursor description. This is a clear gap for no-output-schema tools.

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 descriptions cover page and cursor (67% coverage), leaving per_page undocumented. The description adds context that results are ordered by follower count and capped at 20, which helps interpret per_page. It does not deeply explain parameter interactions like how cursor relates to page, but the schema already provides baseline descriptions.

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 clearly states the tool's action and resource: 'Browse the public DesAira creator directory by follower count (max 20).' The verb 'browse' plus the specific resource and ordering distinguishes it from sibling tools like get_user (single user), get_feed, and search_content.

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 the intended context—browsing a public creator directory ordered by followers—but does not explicitly state when to use this tool over alternatives or when not to use it. No alternatives or exclusions are mentioned, so it stops at implied usage rather than clear guidance.

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