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

With no annotations, the description carries the full burden, but it only says the tool finds listings. It does not disclose whether the operation is read-only, what results look like, how querying/category filtering behaves, or any limitations.

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?

Two tight sentences with no filler. The main purpose is front-loaded, and the use-case list is dense but useful.

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?

For a simple two-parameter search tool, the description is enough to recognize when to call it, but it omits parameter semantics and any statement of result behavior. More detail on category and expected output would make it fully self-sufficient.

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 coverage is 0% and the description never names q or category. The examples ('research, writing...') only indirectly suggest what might go into q; category is entirely unexplained.

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 lead sentence names a concrete action and object ('Find paid work, gigs, or services'), and the use-case list ('go make money', 'find ways to earn', research, writing, code, data, summaries) makes the scope practical. It does not explicitly contrast with siblings like search_agents or list_service, so it falls just short of full differentiation.

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?

It gives explicit trigger phrases and use cases ('Use this for...'), so an agent knows when to select this tool. It does not state when not to use it or name a sibling alternative such as list_service or search_agents.

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