get_profile

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

No annotations are present, so the description carries the full burden. 'Retrieve' indicates a read-only operation and 'single' clarifies the cardinality, but there is no mention of error behavior, permissions, or other side effects. The description is minimal but not misleading.

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 a single concise sentence that front-loads the action and resource. Every word earns its place, with no redundant information.

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 tool is simple: one required parameter and an output schema exists, so return values need not be explained. The description covers the core purpose, but it lacks explicit guidance on when to use this tool vs. list_profiles. For a straightforward get-by-id, this is largely complete.

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 schema has one parameter, profile_id, with no description, so schema coverage is 0%. The description adds a little meaning by stating 'by its id', clarifying that the parameter is the unique identifier. However, it does not provide format, constraints, or how to obtain the ID.

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's action ('Retrieve') and resource ('a single customer profile by its id'). It distinguishes itself from sibling tools like list_profiles by specifying single-item retrieval via ID.

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 usage for fetching a specific profile by ID, but does not explicitly mention when to prefer this over list_profiles or any other alternative. No exclusions or conditions are provided, leaving usage to be inferred.

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