d365fo_test_connection

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

No annotations are provided, so the description must disclose behavioral traits. It only states it tests a connection and returns a JSON string, but does not mention side effects (e.g., whether any state is modified), authentication requirements, or error behavior.

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 purpose, followed by structured Args and Returns sections. It is concise, though it could include more detail within its brevity.

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?

The description fails to provide complete context: no output schema exists, and the description does not specify the structure of the returned JSON, possible errors, or what constitutes a successful/failed test. For a test connection tool, this completeness gap is significant.

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 has 0% description coverage, so the description adds meaning by stating the profile parameter is optional and uses a default if not specified. This adds value beyond the schema, but no further details on valid values or format.

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 tests a connection to a D365FO environment, using a primary verb and resource. However, it does not explicitly distinguish itself from the sibling tool d365fo_test_profile_connection, which likely tests a specific profile connection.

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?

No guidance on when to use this tool versus alternatives, such as d365fo_test_profile_connection. It does not provide context for when or when not to use it.

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