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

Annotations already communicate read-only behavior, and the description does not contradict that. It adds useful behavioral context beyond the annotations by describing what kind of results are returned: trending badges, rising upvotes, and product award winners over the chosen period. This sets expectations for a list of ranked or signal-bearing products rather than a plain catalog response.

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, focused sentences with zero filler: the first states the core operation, the second gives the user-intent trigger, and the third describes the expected result. It is front-loaded and compact.

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?

The tool is simple: 3 optional parameters with complete schema descriptions, no output schema, and a read-only annotation. The description covers what the output generally contains, so the agent has enough context to select and invoke the tool correctly without missing critical behavior.

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 the baseline is 3; the parameters themselves are already described well in the schema. The description adds little parameter-specific detail beyond restating the 'period' concept, so no extra compensation is needed but also no added value is provided.

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 uses a specific verb ('lists') and resource ('software products currently trending on PeerPush'), and specifies the period dimension. It also distinguishes the tool from siblings like new_launches by focusing on community momentum, trending badges, rising upvotes, and award winners, so an agent can tell sibling tools apart.

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?

The description explicitly states when to use this tool: when the user asks what tools are popular, hot, or gaining momentum right now. It does not name explicit exclusions or alternatives, but the context is clear enough to route the agent to this tool.

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