giphy_trending

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered. The description adds no behavioral context beyond that — nothing about rate limits, API-key failure behavior, or whether trending results are region-scoped — so it contributes little beyond the structured fields.

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?

One short sentence, front-loaded with the verb and resource, with zero filler. There is nothing to trim and nothing buried.

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?

This is a simple read-only list tool with full schema documentation and complete annotation coverage, so the description is nearly sufficient as-is. The only missing piece an agent might want is whether results are a flat list and how paging/top-N behavior works, which is minor here.

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%: limit carries its max 50 and default 10, rating carries its enum, and api_key is described. The description adds nothing about parameter behavior (e.g. that limit caps at 50 or that rating filters results), so the baseline of 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?

The description pairs a specific verb ("Get") with a specific resource ("trending GIFs") and names the provider. It is clear on its own, though it never explicitly contrasts itself with the sibling tools giphy_search and giphy_random; the distinction is inferable from the word "trending" but not stated.

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 only implied: an agent can infer "use this when you want currently trending GIFs rather than a search term." There is no explicit when-to-use, no exclusion, and no mention of giphy_search or giphy_random as alternatives, so it stops short of the 4-5 tier.

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