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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully structured. The description adds nothing behavioral beyond that (no pagination behavior, no result-size or ranking caveats), which is acceptable given the rich annotations but earns no extra credit.

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?

A single sentence with no filler, front-loading the verb and the resource. Every clause earns its place by naming the entity kinds and the search axes.

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 an output schema present and annotations carrying the safety profile, the definition is nearly complete for a read-only search. The only meaningful gap is routing guidance relative to the numerous sibling tools, which the description leaves for the agent to infer.

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 are already documented in the schema, including the 'q' search axes, 'kind' enum, 'lang' enum, and 'continuation'. The description's mention of name/house/note/mood word largely restates the 'q' schema text and adds no format or syntax detail, so the baseline of 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?

The description gives a specific verb ('Find') and resource set ('perfumes, houses and raw materials in the Scento Compendium'), plus the retrieval axes (name, house, note, mood word). It clearly differentiates the tool as a lookup/search, but never names which sibling tools it supersedes or complements, so sibling differentiation is left implicit.

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 only implied by the word 'Find'; there is no explicit when-to-use guidance and no mention of alternatives such as material-match, note-portrait, or house-portrait, which plausibly overlap with this tool's search surface. An agent must infer that this is the general name/note lookup versus the specialized portrait tools.

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