follow_topic_blogger

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

There are no annotations, so the description carries the full disclosure burden. It does reveal one meaningful side effect — the blogger's content becomes readable afterward — but says nothing about idempotency on duplicate follows, what a failed link resolution looks like, permission requirements, or what is returned on success.

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?

A single short sentence with the action and destination front-loaded and no filler. It is efficient, though brevity contributes to the missing behavioral detail rather than compensating for it.

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 mutation-style subscribe tool with no annotations and no output schema, the description omits duplicate-handling, error behavior, and the fact that a subsequent read step (list_topic_blogger_contents) is needed to actually retrieve content. An agent would have to guess at edge-case handling.

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 67% and the schema already documents both required parameters (link as profile/share URL, topic_id as knowledge base ID). The description's phrase 指定知识库 only echoes topic_id, and the platform parameter is left entirely undefined in both places — acceptable only because it is a single-value enum with a default.

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 names a specific verb (订阅/follow), a specific resource (抖音博主), and a destination (指定知识库), and adds the downstream consequence that its content becomes readable. It is clearly distinguishable from list_topic_bloggers and get_blogger_content_detail, though it does not explicitly contrast with the near-identical follow_topic_live sibling.

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?

It implies the workflow (subscribe now, read the blogger's content later) but never states when to use this versus follow_topic_live, or what to do if the blogger is already subscribed. No preconditions, no exclusions, and no named alternatives are given.

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