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

Annotations already declare read-only, idempotent, open-world, and non-destructive behavior. The description adds valuable context beyond annotations: no authentication required, searches public data only, and supports agent availability and opportunity-intent filtering. No contradiction with annotations.

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 concise: a clear trigger sentence, a workflow hint, and a compact JSON example. Every sentence earns its place, and the most important information is front-loaded.

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 full schema descriptions, annotations, and an output schema present, the description only needs to clarify access, scope, and entry-point positioning—all of which it does. Nothing essential for correctly invoking this search tool is missing.

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 schema already documents all parameters clearly. The description adds a compact example and maps search dimensions to parameters, but this is illustrative rather than necessary; 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?

The description clearly states the tool's function: finding public developers by skill, name, language, location, agent availability, or opportunity intent. It also positions itself as the discovery entry point ('Start discovery here'), which differentiates it from siblings like get_developer_profile or get_trending_developers.

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 provides an explicit trigger ('Use when the user wants to find public developers...') and useful context such as 'no authentication is required'. It does not explicitly name sibling alternatives or exclusion conditions, but 'Start discovery here' implies when in the workflow this tool should be used.

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