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 return-scope context ('the full text ... with its questions and answers'), which matters because there is no output schema, though it says nothing about not-found behavior for a bad slug.

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?

One sentence, front-loaded with what is returned, no filler or redundancy. Every clause 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 simple one-parameter read with strong annotations, the definition covers purpose, input provenance, and return shape, so an agent can call it correctly. The only gap is that error or empty-result behavior for an invalid slug is not mentioned.

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 slug parameter already carries concrete examples, so the schema does the heavy lifting. The description still adds value by stating the provenance of the slug (it comes from list_estate_sale_guides), which the schema does not say.

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 (read), resource (one guide), and scope (full text with Q&A) in a single clause. It also implicitly distinguishes itself from the sibling list_estate_sale_guides by noting the slug is what that tool returns.

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 reference to 'the slug list_estate_sale_guides returns' tells the agent it should enumerate guides first and then fetch one, which is a clear usage path. It stops short of explicit when-not-to-use guidance or naming alternatives like get_estate_sale.

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