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

Annotations already declare readOnlyHint=true, openWorldHint=true and destructiveHint=false, so safety is covered. The description adds genuinely useful operational context beyond that: no automatic retries/pagination, and a directive to preserve provider fields and metric units (data fidelity caution). It still omits return shape and what error conditions look like.

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?

It is short and front-loaded, but the leading sentence is a tautological restatement of the title, so not every sentence earns its place. The two substantive sentences are compact and useful.

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?

With no output schema, the description should tell the agent what a 'Live Detail' response contains (metrics, host info, units), but it does not. For a read-only detail endpoint requiring an id from a prior search, the description leaves the returned payload entirely opaque.

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% and all three parameters (id, country, include) are documented in the schema with identity-preservation notes. The description adds nothing about parameters, so the baseline 3 applies when the schema carries the burden.

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 'TikTok Live Detail,' which merely restates the tool title rather than stating a verb and resource (e.g., 'retrieve full details for a TikTok livestream'). An agent can loosely infer it fetches livestream data from the name, but the description itself adds no differentiating information versus siblings like nexscope_chuhaijiang_tiktok_live_search.

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?

There is no guidance on when to use this tool versus alternatives such as the live_search sibling or nexscope_data_kd_livestream_detail. The 'no automatic retries or pagination' note describes execution behavior, not usage conditions or prerequisites.

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