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

Annotations already declare readOnly, idempotent, openWorld, and non-destructive behavior, so the safety profile is covered. The description adds genuinely useful context beyond that: 'No LLM call, deterministic,' telling the agent this is a fast, reproducible computation rather than a generative one.

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 tightly written sentences with zero filler. The core content is front-loaded and the sibling pointer is correctly placed last.

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?

With no output schema, the description carries the burden of describing the return content, which it does (top notes, accords, families) while annotations cover the safety profile. It is nearly complete; only visibility/access semantics of 'public' are left implicit.

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 coverage is 67%, with username and the heavily-specified context parameter documented in the schema while response_format has no description. The description adds no parameter-level meaning (e.g., what 'public' implies about visibility), so it neither compensates for nor improves on the schema.

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?

Names a specific verb ('Get') and resource ('a user's public taste profile') and spells out exactly what it contains: top notes, accords, and families derived from collection and reviews. It also distinguishes itself from user_taste_compare, so an agent can route without opening the schema.

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?

Provides a clear routing pointer with 'See also: user_taste_compare for compatibility between two users,' naming the alternative and its purpose. It lacks an explicit statement of when NOT to use it (e.g., versus user_taste_summary) but the context is clear enough to select correctly.

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