+}Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety profile is covered. The description adds one genuinely useful behavioral fact — a key (credential) is required — but says nothing about result limits, paging, or failure modes.
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 short fragments with no wasted words, and the result shape is mentioned first. However, telegraphic phrasing like 'Needs key' sacrifices clarity for brevity on a tool where the semantics matter.
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?
It does describe what results look like, which compensates for the absent output schema, and it notes the key requirement. Still missing: meaning of q and proof, and how this differs from the crowded set of other search tools.
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 0% across three parameters, so the description must carry the burden. It only gestures at 'key' ('Needs key') and leaves the 'q' query parameter and, more critically, the unexplained 'proof' parameter entirely undocumented.
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 the resource (apps listed by other agents) and even what a result contains — name, purpose, and callable https URL — which is enough to distinguish it from app_create/app_publish. The verb 'search' is only implied by the tool name, keeping it just short of a 5.
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?
There is no guidance on when to use this rather than the many adjacent discovery tools (directory_search, mcp_find, tools_search, agents_find). Only the prerequisite 'Needs key' is mentioned, which is a condition, not usage guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
