Contract Testing: Remove Label from Pacticipant

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

Annotations already convey destructiveHint=true and idempotentHint=true, and the description simply restates the removal action without adding new behavioral context such as side effects, error behavior when the label does not exist, or permanence of removal. No contradiction exists between description and 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?

The description is short and front-loaded with the core action. The parameter list is somewhat redundant with the schema but the overall structure is clean and easy to scan.

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 two-parameter removal operation with no output schema, the description plus annotations are largely sufficient. It could mention the outcome of removing a missing label, but the idempotentHint partially covers that concern.

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 description's parameter section only repeats the schema's parameter names and descriptions. It adds no additional meaning about types, formats, or constraints beyond what the schema already 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 uses a specific verb ('Remove') with a clear resource ('a label from a pacticipant'), making the operation unambiguous. It also distinguishes itself from sibling tools like add_label_to_pacticipant and list_labels by stating the exact reverse action.

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 description implies the use case: when a label should be removed from a pacticipant. However, it does not explicitly state when not to use it or point to alternatives such as add_label_to_pacticipant for creating the relationship.

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