-}New value: +nullDoes 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 safety and repeatability are covered structurally. The description adds nothing beyond that: it does not say whether the prompt is static or personalized by attended_at, nor whether a missing event_id fails or degrades gracefully.
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 sentence with no filler or redundancy. It is front-loaded with a usage trigger, though leading with what the tool returns rather than 'Use this when...' would be marginally stronger. Nothing in the sentence is wasted.
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 two-parameter read tool with no output schema, the description should at least indicate what the returned prompt looks like and how the required event_id and optional attended_at influence it. Neither is addressed, so an agent knows roughly when to call it but not what to expect back or how the parameters shape the result.
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 only 50%: attended_at is documented in the schema, but required event_id is undocumented in both the schema and the description. The description compensates for none of this gap and never references either parameter, leaving the required identifier's expected format and role unspecified.
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 uses an action phrase ('Use this when a user needs...') and names the resource ('post-event feedback prompt'), so the general purpose is inferable. However, it never states what is actually returned — a templated prompt string, a set of questions, or a personalized message — and it does not distinguish itself from siblings like record_event_feedback or get_event_preferences. Adequate but vague on the actual output.
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?
It gives one conditional trigger ('when a user needs a short post-event feedback prompt'), which is a real usage context. It offers no when-not conditions, no prerequisites (e.g. the event must exist), and never routes to an alternative such as record_event_feedback, which is the natural counterpart for capturing the feedback this prompt solicits.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
