Contract Testing: Create Pacticipant

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

Annotations already indicate non-read-only and non-destructive nature. The description adds only one behavioral note: the name cannot be changed after creation. It does not disclose idempotency, error behavior, authentication requirements, or what happens on duplicate names.

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 concise, with a clear introductory sentence followed by a structured parameter list. Every element is relevant. Slightly longer than ideal but still efficient.

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?

Given 6 parameters and no output schema, the description covers all parameters but omits return value, error conditions, and required permissions. It is adequate for a simple creation tool but leaves gaps for an agent to handle edge cases.

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 100%, so the baseline is 3. The description adds marginal value by noting that 'name' cannot be changed after creation, which is not in the schema description. However, most parameter descriptions are copied verbatim from the schema, providing no extra semantic clarity.

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 states the tool registers a new application/service (pacticipant) in the workspace. The verb 'register' and resource type are specific. While it does not explicitly differentiate from sibling tools like update_pacticipant, the 'new' keyword and tool name make the creation purpose 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 description provides no guidance on when to use this tool versus alternatives (e.g., update_pacticipant or delete_pacticipant). It only describes the action, leaving the agent to infer usage context from the name.

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