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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so the agent knows this is a safe, repeatable, local read. The description adds the breadth of returned data (what/where/when/how/status), but says nothing about pagination, result caps, or the fact that returned plantings may span multiple gardens.

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 tight sentences that front-load the action and resource, then follow with concrete usage triggers. There is no filler and nothing that fails to earn its place.

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, closed-world, annotation-covered list tool with a fully documented schema and no output schema, the description is nearly sufficient. It could go further by clarifying how it relates to list_planned_plantings and get_history, but nothing needed to call it correctly is missing.

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% with all three params documented, so the schema carries the load and baseline 3 applies. The parenthetical 'what, where, when, how, current status' loosely echoes the filters but adds no syntax, default, or matching semantics beyond what the schema already states.

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 ('List the user's plantings') and expands the scope with what/where/when/how/status. It is clear on its own, but it never distinguishes itself from the many sibling listing tools, notably list_planned_plantings (planned vs. actual) and get_history/get_plan.

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?

The second sentence gives concrete triggering intents: what was planted, when something was sown/transplanted, what's growing in a bed. That is strong positive guidance, but there is no when-not or explicit pointer to alternative tools like list_planned_plantings or get_history.

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