get_pins

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

With no annotations, the description carries the burden. It adds value by mentioning that results include sentiment analysis and trend information. However, it does not disclose pagination behavior, authentication requirements, or the read-only nature explicitly, leaving some behavioral gaps.

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, concise sentence that front-loads the verb and resource, then adds key features. Every word earns its place; there is no redundancy or filler.

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 list tool with 6 parameters and no output schema, the description provides essential context but lacks depth. It does not explain the return structure beyond mentioning sentiment/trend info, nor does it differentiate from the many analysis sibling tools. Schema covers parameter details, but the description could better frame when this tool is appropriate.

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%, so the baseline is 3. The description only loosely mentions 'topic, sorting, etc.', which does not add meaningful detail beyond what the schema already provides. It does not explain parameter interactions or values.

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 clearly states the tool retrieves a list of Juejin pins ('获取掘金沸点列表'), specifies it supports topic and sorting parameters, and distinguishes it from siblings like get_articles and search_pins by focusing on pin listing with sentiment/trend info.

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?

Usage is implied: for getting a list of pins. However, there is no explicit guidance on when to use this vs. alternatives like search_pins or analyze_trends, nor any exclusion criteria. The description does not mention alternatives or when-not-to-use scenarios.

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