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

Annotations declare readOnlyHint=true, so the safety profile is covered. The description adds genuinely useful behavior beyond that: the paginated response shape ('Returns a page plus `next`/`previous`') and the underlying endpoint, which is valuable given there is no output schema.

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?

Two compact sentences: purpose first, then return/pagination and endpoint. No filler, nothing redundant, and the most important information is front-loaded.

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 read-only list tool with fully documented parameters, the description covers purpose, filtering dimensions, and pagination behavior. With no output schema, a slightly richer account of returned fields would help, but nothing essential is missing.

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?

Schema description coverage is 100%, so all four parameters (page, doctor, patient, page_size) are already documented in the schema with defaults and bounds. The description's mention of filtering by patient or doctor adds nothing beyond that. Baseline 3 applies.

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?

Specific verb ('List') plus resource ('patient allergies') with the filterable dimensions named, so the agent immediately knows what it returns. It doesn't explicitly contrast itself with siblings like drchrono_list_medications or drchrono_list_problems, but the unique resource makes it distinguishable.

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 says it is filterable by patient or doctor but gives no when-to-use context, prerequisites, or alternatives. There is no guidance on when a patient-scoped allergy listing is preferable to other clinical list tools.

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