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

Annotations already declare destructiveHint=true and openWorldHint=false, so the "Closed-world" and "Destructive" lines largely restate structured data. The genuinely additive information is that this is a *soft* delete that "can be undone," which is useful, but the hedged phrasing ("may be executed," "can be undone if necessary") leaves the reversibility mechanism unclear.

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?

The purpose is front-loaded in the first sentence, which is good. The trailing safety block repeats annotation content and pads the definition without earning its 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?

An output schema exists, so return values need no explanation. However, for a delete operation on a trip that presumably owns activities, expenses, and documents, the description never says whether those cascade or survive, which is the key unknown an agent faces before calling it.

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% and the single parameter is documented as "Tripsy resource id." The description only adds "by id," contributing essentially nothing beyond the schema, so the 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?

The first sentence gives a specific verb and resource ("Soft-delete a Tripsy trip by id"), which cleanly separates it from trips_update and trips_show. It stops short of distinguishing it from the other *_delete siblings, but the resource scope is unambiguous.

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?

The only usage statement is "Delete operations may be executed when requested and can be undone if necessary," which is circular and gives no condition for choosing delete over trips_update. No prerequisites, no exclusions, and no mention of what happens to child records are provided.

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