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

Annotations already cover the safety profile (readOnly, idempotent, closed-world), and the description adds valuable behavioral context: the breadth and shape of the returned payload (ratings, calendar, photos with credits) and the fact that houseplants receive an additional indoor profile. No output schema exists, so this return-content disclosure is doing real work. It omits any behavior for unknown or ambiguous plant names.

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?

Front-loaded with the resource and scope, then a dense enumeration of contents. The list is long but each item is a legitimate return-content hint that compensates for the absent output schema, so little feels wasted.

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 adequately characterizes what comes back, including the conditional indoor profile for houseplants and photo credits. It leaves minor gaps: no handling of not-found or ambiguous names and no hint that other sibling tools cover indoor-only or search use cases.

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 100% and the single parameter already documents slug, common, botanical and Arabic name forms plus typo tolerance. The description restates exactly that, adding no new syntax, format or ambiguity-resolution detail beyond 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?

States a clear resource ('Everything about one plant in Dubai') and enumerates what the profile contains, so an agent knows this is a comprehensive single-plant lookup. It is distinguishable from search_plants, though it does not name the sibling and partly overlaps with get_indoor_plant_guide by mentioning the 'Indoors in Dubai' profile.

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 rather than stated: 'Everything about one plant' suggests a detail lookup rather than search, but there is no explicit when-to-use, when-not-to-use, or routing to search_plants or get_indoor_plant_guide. No prerequisites or fallback guidance is given.

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