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

The description adds real behavioral context beyond the annotations: no automatic retries, no pagination, and no transformation of provider fields/metric units. However, annotations declare readOnlyHint=false and openWorldHint=true, and the description does not reconcile why a "detail" lookup is flagged as non-read-only, nor does it describe response 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?

Three short sentences with no filler, but the first sentence merely repeats the title and consumes the front-loaded position that should carry the actual purpose. The remaining sentences are terse but 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 and only sparse annotations, the description must explain what a "live detail" returns and how it differs from the related search/related-products tools. It only hints at output handling ("preserve provider fields and metric units") without describing the payload, leaving an agent unable to predict results.

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 id, country, and include are already documented in the schema (including the note that the id comes from its search operation and country_code may differ). The description adds nothing about parameter meaning or format, so the baseline 3 applies.

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 by restating the tool name/title ("TikTok Live Detail") without a verb or resource statement -- it never says it retrieves livestream metrics/detail records by ID and country. It also fails to distinguish this from siblings like nexscope_chuhaijiang_tiktok_live_search or nexscope_chuhaijiang_tiktok_live_related_products.

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?

"Execute only this operation; no automatic retries or pagination" is an operational caution, not usage guidance. There is no statement of when to call this versus live_search (which supplies the required id), and no preconditions or exclusions are given.

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