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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds the useful context that it only returns public design artifacts ('public' is not in the schema but is in the description). It does not disclose pagination behavior or rate limits, but given the annotations, this is adequate.

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 sentence with no redundant words. It front-loads the purpose and includes the key qualifiers ('public', 'recently posted or top-ranked') without any filler. This is exemplary conciseness.

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?

Given that an output schema exists (so return values are covered elsewhere) and annotations cover safety, the description explains the core behavior well. It mentions the public scope and the ordering options. The only minor gap is that it doesn't explicitly note that the tool is a feed/browse operation rather than a search, but that is reasonably inferred. Overall, it is complete for its simplicity.

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%, and the schema describes both sort and limit with clear defaults and ranges. The description's 'recently posted or top-ranked' essentially paraphrases the sort enum values, adding no new meaning beyond what the schema already provides. Since the schema handles the heavy lifting, the baseline of 3 is appropriate.

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 states a specific verb ('Browse') and a clear resource ('public design artifacts') with qualifiers ('recently posted or top-ranked'). It distinguishes from siblings like search_snacks by implying a discovery feed rather than a targeted search. However, it does not explicitly name alternatives, so it loses a point for not fully preempting confusion.

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 implies usage for browsing recent or top content, and the sort parameter clarifies the two modes. However, it does not explicitly state when to use this over search_snacks or get_snack, nor does it list exclusions. The 'public' qualifier conveys that it is limited to public artifacts, which is helpful, but the guidance is implicit rather than explicit.

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