xhs_get_note_sub_comments_by_comment_id

Read-only

根据 note_id 和一级评论 comment_id 获取二级评论；用户已提供完整合法的 ID 组合时直接使用；已有 note_id 或笔记链接但缺少必需 ID 时，调用对应一级评论工具补全；缺少笔记定位信息时向用户索取；支持 page_token 翻页。

Input Schema

Name	Required	Description
`note_id`	Yes	note_id 是小红书笔记 ID。已有完整 note_id 时原样使用；否则可从笔记搜索、笔记详情、评论、标签页笔记列表或用户发帖列表结果复制；不得截断、缩写、脱敏、补全、格式化、重组，也不得只传前缀。
`comment_id`	Yes	一级评论 ID；用户已提供时直接使用，否则可从一级评论结果 items[].comment_id 复制；不要传二级评论项自身的 comment_id。
`page_token`	No	分页令牌。首次请求留空；继续翻页时必须将上一页返回的完整 next_page_token 原样作为 page_token 传回。page_token 是不透明分页令牌；只能用于同一 note_id 和 comment_id 的二级评论列表，不能跨笔记或一级评论复用；不得修改、截断、缩写、脱敏、掩码、省略、规范化、重组或自行生成，不得用省略号替换中间内容。

Output Schema

Name	Required	Description
`items`	Yes	当前页二级评论列表
`points`	Yes	本次成功调用的积分消耗与账户积分余额。
`next_page_token`	Yes	下一页不透明分页令牌；为空表示没有更多结果。继续翻页时必须将返回的完整 next_page_token 原样作为 page_token 传回。next_page_token 只能用于同一 note_id 和 comment_id 的二级评论列表，不能跨笔记或一级评论复用；不得修改、截断、缩写、脱敏、掩码、省略、规范化、重组或自行生成，不得用省略号替换中间内容。

TDQS

A4.4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds real behavioral context beyond that: the tool depends on a prerequisite call chain to obtain a first-level comment_id, and results are paged via page_token. It does not describe ordering or how many sub-comments come back per page, which keeps it short of a 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One compact sentence sequence with semicolon-delimited branches, front-loaded with the core action followed by the fallback conditions. No filler or redundant restatement of the name.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema, full parameter descriptions, and annotations in place, the description supplies the remaining missing piece: the prerequisite chain and paging behavior. Minor gaps such as pagination completeness or ordering are non-critical for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the property descriptions already spell out ID provenance and the opaque page_token rules in detail. The description only echoes 'supports page_token paging' without adding format or constraint detail beyond the schema, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource in the opening clause: fetch second-level (sub) comments for a given note_id and first-level comment_id. This clearly separates it from the first-level comment tools in the sibling list, and it names the sibling category (一级评论工具) that produces the required comment_id.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives explicit branch logic: use IDs directly when the user supplies a complete valid pair; fall back to the first-level comment tool when note_id or link exists but the required ID is missing; ask the user when note-location info is absent. When-to-use, when-to-fall-back, and when-to-ask are all covered.

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