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

Annotations already declare readOnly/openWorld=false/destructive=false, and the description adds genuinely useful behavior: lists are returned complete even when the website collapses them, and industry pages include parent/vertical links. It stops short of noting any caching or rate-limit behavior, but coverage is solid for a read tool.

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?

Front-loaded with the core action and followed by the coverage inventory, which is dense but earns its place. The middle enumeration of path families is long and somewhat run-on, though it is informative rather than 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?

Output schema exists, so return values need not be described, and the description fully covers what is retrievable, which path forms are valid, and which content classes are excluded. Nothing an agent needs to call it correctly is missing.

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 description coverage is 0% and the single `path` param has no schema-level documentation, so the description must carry it. It does: it specifies canonical path or URL and lays out the accepted path grammar (/industries/{slug}/{question}, /best/{line}/{segment}), giving the agent concrete input formats.

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?

Names a specific verb (Retrieve) and resource (published Spot page) and enumerates the concrete path families it serves (/industries, /best, provider profiles, comparisons, reviews, rankings), which clearly separates it from the sibling search_* and ask_* tools. An agent can tell what this returns without opening the schema.

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?

Gives explicit when-not conditions: drafts, customer-specific guides, submissions, and unknown paths are unavailable, which prevents dead-end calls. It does not name a fallback sibling (e.g., use search_knowledge for drafts), so the routing guidance is strong but not exhaustive.

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