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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed-world scope, so the safety profile is covered. The description adds that queries are interpreted loosely from plain language with examples, but says nothing about result ranking, how the limit is applied, or what a match looks like.

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?

A single front-loaded sentence that states the action first and then illustrates it with examples. Every clause earns its place; it is tight, though the examples make it slightly longer than strictly needed.

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 read-only search tool with no output schema, the description covers the query intent well but omits default result count (limit=5) and any hint about result shape or ranking. Adequate but with visible gaps.

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 50%: query has a short description while limit has none. The description usefully clarifies that query is a natural-language need (with three examples), but it never addresses limit or its 1-10 range, so it only partially compensates for the coverage gap. Baseline 3 fits.

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?

States a specific verb (Find) and resource (UltraTech Pakistan services) and clarifies the query modality with concrete examples like 'cameras for my shop' and 'FBR invoicing'. It does not explicitly contrast itself with list_services or get_service, which is the only thing keeping it from 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?

The 'plain language' framing implies this is the semantic-search path rather than browsing, but the description never states when to prefer it over list_services or get_service. No exclusions, prerequisites, or fallbacks are given, so the routing must be inferred.

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