github_trending_developers

Read-only

List developers currently trending on GitHub with their public profile details. Use this no-argument snapshot to discover rising accounts, rather than search for a specific username.

A4/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds the 'snapshot' framing, but says nothing about return volume, pagination, or refresh cadence. It also calls itself 'no-argument' while the schema exposes two optional filters, which could lead an agent to skip available narrowing.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, both earning their place, with the core purpose front-loaded and the usage directive second. No filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be explained, and the safety profile is carried by annotations. The remaining gap is the mild tension between 'no-argument snapshot' and the two documented filters, which is a small but real incompleteness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and both parameters (since, language) have descriptions, so baseline is 3. The description adds no filter guidance and its 'no-argument' phrasing actively undersells the two filters the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('List developers currently trending on GitHub') plus the payload ('public profile details'), which lets an agent separate it from github_user and github_search_users without opening the schema. It also frames itself as a discovery snapshot rather than a lookup.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly tells the agent when to reach for this tool ('discover rising accounts') and when not to ('rather than search for a specific username'). It stops short of naming the sibling search tool, so routing is implied rather than pinned to a specific name.

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