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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description contributes ordering ('newest first') and the shape of returned rows, which is genuine added value. It says nothing about pagination behavior or whether a truncated result set is signalled, which is the main remaining behavioral gap for a list tool capped at 100 rows.

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?

A single compact sentence with the resource front-loaded and no filler. It reads as a noun phrase rather than a complete statement, but every clause (source, ordering, returned fields) carries information.

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?

There is no output schema, so the description usefully enumerates the returned columns and the sort order. With only four fully documented parameters and complete annotation coverage, the definition is sufficient to invoke the tool correctly; only pagination semantics are left unstated.

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%, so all four parameters (limit, search, status, site_id) are already documented, including the enum values and the site_id resolution hint. The description adds no parameter-level meaning beyond the schema, so the baseline of 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?

The description names a specific resource ('messages visitors sent through the feedback widget') and adds scope details: ordering ('newest first') and returned fields ('id, status and the page'). It is clearly distinguishable from siblings such as list_visits or list_links, though it never states an explicit verb like 'List' and doesn't name an alternative.

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 no when-to-use guidance and no mention of alternatives or exclusions (e.g. when to use list_feedback vs. other visitor-data tools). Usage is only inferable from the resource name, so the agent must guess the context in which this tool is appropriate.

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