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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so the safety profile is covered. The description adds real behavioral context: what each section contains, that omitting 'month' returns the guide alone, and that every plant is linked — but it says nothing about response size or pagination for a potentially large 'all' payload.

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?

The content-scope enumeration is front-loaded and every listed item is meaningful, and the second sentence carries the actionable instruction. The first sentence is long and list-heavy, but it earns its length by mapping the tool's coverage.

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 guide tool with no output schema, the description tells the agent what content exists, how to scope it by section and month, and where to go next. Only the shape/size of the returned guide is unaddressed, which is a minor gap.

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 both parameters (month, section) are already fully documented with enums, ranges and defaults. The description restates section meanings and the 'leave it out' behavior for month, adding no syntax or format detail beyond the schema; 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?

States a specific verb+resource ('the starting point for anything about houseplants and indoor plants in Dubai') and enumerates the exact content sections it covers, so an agent knows precisely what this returns versus get_kitchen_garden_guide or get_indoor_style. It also names the sibling tools (search_plants, get_plant) used downstream, making its position in the workflow 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?

Gives explicit selection instructions: ask for one named section or 'all', optionally add a month, then shortlist with search_plants and read details with get_plant. The routing from this guide to the two follow-up tools is spelled out with their parameters, leaving nothing to inference.

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