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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds only a light behavioral note ("Returns the most recently published products") and no pagination, result-count, or ordering semantics, which is the minimum-plus for a tool whose annotations already carry the safety burden.

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 the purpose front-loaded and zero filler. The closing linking advice is slightly output-oriented but useful and compact; nothing is padded.

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, the description carries return-value burden and does mention the key URL fields (websiteUrl, peerpushUrl) an agent should surface. It leaves ordering and result-shape details thin, but the schema fully covers inputs and annotations cover safety, so an agent can call this correctly.

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 days, limit, and category are already documented with defaults and bounds in the schema. The description alludes to the days window but adds no meaning beyond it, 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?

States a specific verb and resource ("Lists products recently launched on PeerPush") plus a scope constraint ("within a chosen number of days"). It is clearly differentiated in kind from mutation siblings like peerpush_create_product, though it does not explicitly contrast with the closest read siblings such as peerpush_trending or peerpush_discover.

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?

Gives an explicit trigger condition: "Relevant when the user asks about newly launched products or recent software releases." That is clear when-to-use context, but it names no alternatives or exclusions, so an agent must still infer why this beats peerpush_trending or peerpush_deals.

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