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

With no annotations, the description carries the burden of explaining behavior. It accurately conveys that this is a keyword search across NSFW content, which is useful context. However, it does not disclose result ordering, pagination, content-filtering, or whether results are grouped by type, leaving some behavioral ambiguity.

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, front-loaded sentence with no filler. Every phrase contributes to the agent's understanding of the tool's scope and query semantics.

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 one-parameter search tool with no output schema, the description is adequately complete: it identifies the platform, the keyword-based nature, and the three content categories searched. It could specify whether results are combined or separate, but this is not critical for initial invocation.

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 coverage is 100%, as the q parameter is described as 'Search query'. The description adds the term 'by keyword', which slightly clarifies q as a keyword string, but this is largely redundant with the schema. Baseline 3 is appropriate.

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 states a specific action ('Search'), a specific platform ('DesAira'), and specific result types ('adult videos, hashtags and creators'). It clearly distinguishes from siblings like get_feed and list_creators by indicating keyword-based search across multiple content types.

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 use for keyword-driven discovery across videos, hashtags, and creators, which differentiates it from browsing or direct retrieval tools. However, it does not explicitly state when to prefer this tool over siblings like list_creators or list_tags, nor does it mention any exclusions.

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