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

Annotations already mark the operation as destructive, so the description correctly moves beyond that by disclosing a non-obvious consequence: the id is not reissued and the gap in the TR series is a record of removal. This adds meaningful behavioral context without contradicting 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 sentences carry a complete message with no filler. The action and required identifier are front-loaded, and the important consequence about id reissuing is stated briefly and clearly.

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?

This is a simple single-parameter destructive operation with annotations covering the safety profile, so the description does not need to explain return values or auth. It covers the input format, purpose, and an important behavioral consequence, leaving no critical gaps for correct invocation.

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?

The schema already documents the single parameter with an exact description and example, and schema coverage is 100%. The description reinforces the exact-match requirement and format, but does not add substantial semantic detail beyond what the schema provides.

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 states a specific verb ('Remove'), a precise resource ('one trip from the mileage log'), and a required identifier format ('exact TR-YYYY-NNNN id'). It also gives the intended purpose ('for entries made by mistake'), making it clearly distinguishable from siblings like trip_add and trip_list.

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 phrase 'for entries made by mistake' provides clear context for when this tool is appropriate. It does not explicitly name alternatives or exclusions, but the single-purpose nature of the tool and the exact-id requirement make the usage context reasonably clear.

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