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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds that the result includes availability plus links, but says nothing about freshness of the data, whether lookups can fail for unknown projects, or the shape of the response.

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 short sentence with no filler, and the resource being looked up is front-loaded. Nothing in it is wasted or redundant.

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-parameter read tool with no output schema, the description is nearly sufficient, but since there is no output schema it should say more about what "availability" and "links" actually are so an agent can interpret the result.

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% with a single enum-constrained parameter, so the schema already fully documents the accepted values. The description restates the valid values (Meridian, Dock) but adds no semantic meaning such as case sensitivity or behavior for missing products, so the 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?

States a specific verb ("look up") and resource ("Meridian or Dock product availability and links"), so an agent can tell what it retrieves. The sibling tools are entirely unrelated, so no differentiation is needed, but the description leaves "availability and links" somewhat abstract relative to the tool name's "status".

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?

Usage is only implied: the reader infers you call this when you need status for one of the two named products. There is no explicit when-to-use, when-not-to-use, or prerequisite statement, though the absence of any overlapping sibling lowers the cost of that gap.

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