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

Annotations already declare this a safe read. The description adds genuine context: the content is marketing-approved copy, fees are examples, and the disclosures returned must be shown word for word before purchase, which affects how an agent uses the result. It does not describe the return structure, but the added disclosure obligation is real behavioral value.

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?

Only the first sentence describes this tool; the remaining roughly 200 words are an unrelated multi-step workflow plus a verbatim list of eleven disclosures that will also come back at runtime in the quote. The description is front-loaded correctly but is dominated by content that does not earn its place here.

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 parameterless, read-only tool with no output schema, the agent mainly needs to know what comes back and in what shape; the description gives the categories (descriptions, example fees, disclosures) but not their structure or per-line organization. The heavy workflow material is complete for the broader flow but misplaced on this definition.

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?

Zero parameters, so the schema baseline applies. The description correctly implies no inputs are needed for the catalog lookup, and the implicit inputs it does mention (email, declarations fields) belong to other tools in the flow, not this one.

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 opening sentence names a specific resource and enumerates its contents (marketing's approved description, example fees, disclosures, per product line and bundle). The retrieval verb is only implied by the name, but an agent can tell this is a read of static catalog content, distinct from siblings like get_quote or create_quote.

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?

There is plenty of workflow guidance, but almost none of it is about this tool: the ordering ('first ask for the consumer's email', then read_declarations_page, then create_quote) and the pre-purchase disclosure requirement describe the surrounding flow. Nothing says when to fetch the catalog itself, or whether to re-fetch per line versus once for the bundle.

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