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

With no annotations, the description carries the full behavioral burden and does reasonably well: enumerating returned fields (growth stage, next-watering timing, harvest payouts) tells the agent concretely what this call surfaces. It never explicitly states that it is read-only and side-effect free, which is the remaining gap for a zero-annotation tool.

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, front-loaded with the resource and followed by a compact list of returned fields. Every clause earns its place and nothing is padded.

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 must convey return content, and it does so by naming the four field groups an agent gets back. Absent are details like how many plots are locked/empty or the ordering of results, but for a zero-argument status tool this is close to complete.

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?

There are zero parameters and the schema is an empty object, so there is nothing for the description to disambiguate. Baseline 4 applies; the description correctly implies no arguments are needed by describing a fixed personal scope ('your six garden plots').

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 uses a specific verb ('See') with a specific resource ('your six garden plots') and enumerates exactly what information is returned: what's growing, stage, next watering time, and harvest payouts. It distinguishes itself from action siblings like plant/water/harvest by being purely a read-only status view, though it never names those siblings explicitly.

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: an agent can infer this is the read path to check garden state before deciding to plant, water, or harvest. There is no explicit 'use this when...' guidance and no mention of the other status siblings (pot_status, sanctuary_status), which would have made the routing unambiguous.

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