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

Annotations already cover read-only, idempotent, and closed-world safety, so the bar is lower; the description adds substantial behavioral context about response contents, the extra 'Indoors in Dubai' houseplant profile, and alias listing under 'Also known as'. It does not disclose what happens when a plant is not found, which is the only notable gap.

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 sentences, purpose front-loaded in the first clause, with no filler or marketing language. The long comma-separated inventory of profile sections is dense but each item conveys real scope rather than padding.

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 returns and does so thoroughly, including the houseplant-specific section and name aliasing. The main omission is failure behavior for an unresolvable name, the single most likely error path for a name-based lookup.

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% and the input description already documents slug, common/trade/botanical/Arabic/local-script names, and typo tolerance in near-identical terms, so this is largely repetition. The only marginal addition is that all resolved names are returned under 'Also known as', which is output rather than input semantics.

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?

States a specific verb and resource ('Everything about one plant in Dubai') and enumerates the profile's contents in detail. It is implicitly distinguishable from search_plants as the single-entity detail lookup rather than a search endpoint, and the name-resolution sentence makes the one-plant scope unambiguous.

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 stating it returns 'everything about one plant' and that it resolves any name form, but no sibling is named and there is no when-to-use vs search_plants guidance or exclusion. An agent must infer that it should search first if it lacks a plant name.

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