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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds the REST endpoint (GET /satisfaction_ratings.json), which is mild extra context, but says nothing about pagination behavior or result volume beyond what the 'page' param already signals. Modest added value on top of annotations.

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?

Two short sentences, zero filler, with the resource and the filtering capability front-loaded. 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 read-only list tool with fully documented parameters, the description covers what it does and how it can be narrowed. No output schema exists, but the description indicates the return subject (CSAT ratings), leaving only minor gaps like default page size or ordering.

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 100%, including the enum values for 'score' and the pagination semantics for 'page', so the schema does the heavy lifting. The description only restates that filtering by score is optional, adding no meaning beyond the structured fields. 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 and resource ('List customer satisfaction (CSAT) ratings') and even gives the underlying REST endpoint, so the agent knows exactly what is returned. It is clearly distinguishable from siblings like list_tickets or list_views, though it does not explicitly name any sibling it must not be confused with.

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?

'optionally filtered by score' implies the main usage context, but there is no explicit when-to-use/when-not guidance or reference to an alternative tool. Adequate but leaves the agent to infer the scenario.

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