Test Contacts Roundtrip

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

With no annotations, the description is the sole source for behavioral disclosure. It states the tool performs a sequence of actions (create, edit, verify, delete) on a dummy contact, suggesting it is a test operation with no lasting side effects. However, it lacks details on error behavior, verification specifics, and what happens if confirm is false.

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 very concise with two sentences and no wasted words. While a bulleted list of actions might improve readability, the current structure effectively communicates the tool's purpose and requirement.

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 the tool is a simple test utility with one parameter and no output schema, the description provides the essential information: the composite action and the confirm requirement. However, it does not explain what 'verify' entails, the expected outcome, or how to interpret results, leaving some gaps for the agent.

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 only parameter, confirm, has no description in the schema (0% coverage). The description adds crucial meaning by stating 'Requires confirm=true,' indicating that the tool only performs actions when confirm is true. This clarifies the parameter's role beyond the schema's boolean type and default value.

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 that the tool creates, edits, verifies, and deletes one dummy contact, which explains the roundtrip testing purpose. However, it does not explicitly distinguish itself from sibling tools like create_contact or delete_contact, which are individual operations for production use.

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 includes a usage condition: 'Requires confirm=true.' This tells when the tool will actually execute. However, it does not provide guidance on when to use this composite test tool versus individual sibling tools, nor does it explain the effect of confirm=false.

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