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

The annotations already declare destructiveHint=true and openWorldHint=false, and the description's 'Closed-world' and 'Destructive' lines largely restate them rather than adding value. The only marginal addition is the auth scope ('authenticated user's Tripsy account and accessible trips'). It says nothing about irreversibility, cascade effects on linked subresources, or failure behavior when the id is invalid.

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 sentences with the operation front-loaded, and no filler. The safety sentence could be tightened since it duplicates annotation data, but nothing is wasted in length.

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 not be explained, and the two required parameters are fully documented. However, for a destructive mutation the description omits the consequences of deletion (irreversible? cascade?) and the auth/permission requirement, leaving meaningful 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 description coverage is 100%, so the schema already defines both required parameters (id and trip_id). The description notes targeting 'by id' but does not clarify the relationship between the hosting id and the parent trip_id or their expected formats, so it adds no meaning beyond the schema.

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 verb and resource ('Delete a Tripsy hosting') plus the identifier used to target it ('by id'), which distinguishes it from hostings_create/list/show/update. It does not explicitly name the sibling it replaces, but the delete verb makes the distinction 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?

There is no guidance on when to delete versus update/archive, no prerequisite checks (e.g., confirming the hosting exists or is not referenced by activities/expenses), and no mention of the required trip_id being a scope parent. The agent must infer all usage context.

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