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

The annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety behavior is covered. The description adds workspace scope, returned fields, and entry-point dependency, but does not explain limit behavior, pagination, ordering, or defaults.

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?

The description is two sentences and front-loads the core action and scope. The field list is dense but useful, and the entry-point guidance follows immediately without filler.

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 read-only list tool with strong annotations, the description covers purpose, scope, returned fields, and entry-point usage. The remaining gap is limit and pagination behavior, which keeps it from being fully complete.

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?

The schema has one optional limit parameter with 0% description coverage, and the description never mentions it. The parameter name and schema constraints provide minimal self-explanation, but the definition does not clarify default value, pagination, or how limit affects results.

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 a specific verb and resource: list the workspace's SEO research projects. It also enumerates the returned fields and explains the tool's role as the entry point for other SEO tools, distinguishing it from siblings clearly.

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 starting-point guidance: 'Start here — every other SEO tool takes a project or cluster id from this list.' This tells the agent when to use it relative to the SEO tool family, though it does not state exclusions or named alternatives.

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