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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false, so the safety profile is covered structurally. The description adds only the returned field list and a use case; with an output schema present, that field list largely restates structured data rather than adding new behavior context such as result counts or limits.

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 clauses; the resource and field list are front-loaded and the usage trigger follows. No filler, though the parenthetical field enumeration is somewhat dense and partly redundant with the output schema.

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 read-only list tool with an output schema covering return shape and annotations covering safety, the description is adequate: it says what comes back, how many by default (via schema) and the typical intent. Only the missing projectId provenance keeps it from being fully self-contained.

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?

At 50% schema coverage, projectId is undocumented in both the schema and the description — no hint about where the id comes from (list_projects). The description adds nothing about the limit parameter either, so it fails to compensate for the coverage gap.

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 resource and scope: the most recent responses for a project, plus the fields carried (summary title, sentiment, quality, channel, share id, date). That distinguishes it from response_detail (single response) and responses_search (filtered search), though it never names those siblings explicitly.

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 usable trigger phrases ('latest feedback', 'surface citable responses'), which implies when to reach for it. It stops short of explicit when-not guidance or naming responses_search / response_detail as the alternatives, leaving the agent to infer the boundary.

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