get_patient_profile

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

No annotations are provided, so the description carries the full burden. It discloses a key behavioral trait: returns null if no profile has been saved. However, it does not elaborate on safety, permissions, or other edge cases, which is acceptable for a simple read operation but not exhaustive.

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 sentence, front-loaded with the action, and includes only the essential extra detail about the null return. No waste or redundancy.

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 tool with no parameters, no annotations, and no output schema, the description covers the main purpose and the most important behavior (null return). It is complete enough for an agent to know when to invoke it and what to expect in the missing case, though it does not describe the payload structure (not required here).

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?

With zero parameters, the schema provides no information to describe. The description does not need to add parameter details, and the baseline for 0 params is 4. The description correctly says nothing about parameters, which is appropriate.

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 action ('Retrieve') and the resource ('saved patient profile information'). It distinguishes itself from sibling tools like set_patient_profile (write), delete_patient_profile (remove), and search_medical_info (different resource).

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?

Usage is implied by the action of retrieving a saved profile, but there is no explicit guidance on when to use this tool versus alternatives. The description does not mention conditions or exclusions, but the simple getter nature makes the intended use reasonably clear.

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