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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description usefully adds that data is 'recorded by the world, not summarised by a model' (i.e. raw factual records), but says nothing about return format, ordering, or pagination behavior beyond the 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 tight sentences that front-load the resource and its contents. The closing phrase is somewhat flavourful, but the definition is appropriately sized and wastes little space.

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 retrieval tool with no output schema and only two parameters, the description gives a reasonable sense of what is returned. It omits pagination/limit behavior and any hint of result shape or volume, leaving minor gaps.

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 coverage is 50%: token is well-documented in the schema, but limit (1-100) has no description and the tool description adds nothing about pagination or what limit controls. The description does not 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?

The description clearly conveys the resource retrieved (memories from stays) and enumerates its contents (who you met, what you did, where you went, what you earned). It is a specific read operation, though it never references or distinguishes itself from siblings like vacation_get_status or vacation_get_relationships.

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, no alternative tools named, and no exclusions offered. The agent must infer that this retrieves historical stay data rather than current status, with nothing to route it against the many sibling getters.

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