Contract Testing: Create Pacticipant

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

Annotations already declare non-readOnly and non-idempotent behavior. The description adds the irreversible property that 'name cannot be changed after creation', which is valuable. It does not cover other behavioral aspects such as duplicate handling, permissions, or response shape.

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 and the toolset categorization is helpful. However, the full parameter list duplicates the schema, making the description longer than necessary without adding informational value.

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 flat six-parameter creation tool with complete schema coverage and annotations, the description covers the essential registration scope and the immutable name constraint. It lacks explicit alternative usage and post-creation behavior, but these are non-critical 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?

The input schema describes all six parameters with 100% coverage. The description's parameter list is a near-verbatim repeat of the schema and adds no extra meaning beyond what is already structured.

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 ('Register'), a resource ('pacticipant'), and the scope ('in the workspace'). It clearly distinguishes this creation tool from its update/patch/delete siblings through the word 'new'.

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?

'Register a new application/service' gives a clear creation trigger and implies the tool is for new resources, not modifications. However, it does not explicitly name alternatives like contract-testing_update_pacticipant for existing resources.

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