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

With no annotations, the description carries the full burden; it does disclose meaningful traits such as case-insensitive fuzzy matching and that only published plans/articles are returned. However it omits behavior on no match, ambiguity handling, pagination, auth, or rate limits, leaving notable gaps.

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 with the verb first and no filler; every clause (matching mode, return content) earns its place.

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 one-param lookup with no output schema or annotations, the description adequately covers what it does and what it returns. It stops short of error/empty-result behavior and sibling differentiation, which are minor for a simple read.

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 100% and the single 'name' param is already documented as 'name or recognizable portion.' The description adds value beyond the schema by specifying case-insensitive fuzzy matching, clarifying match tolerance for the caller.

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 (provider), plus the matching method (case-insensitive fuzzy name) and the return scope (every published plan and article link). It is clear on its own, though it never names or contrasts with the siblings compare_providers or search_vps_deals.

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 fuzzy-name lookup implies you use it when you roughly know a provider's name and want that provider's plans and articles, but there is no explicit when-to-use, when-not, or pointer to compare_providers/search_vps_deals. Usage is only implied.

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