get_zone

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

No annotations exist, so the description carries the full burden. 'Get' implies a read-only, non-destructive call, and the description usefully discloses what the payload contains, but it says nothing about auth requirements, error behavior for unknown IDs, or whether the data is cached/live.

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 front-loaded sentence with a colon-delimited field list and no filler. The enumeration is slightly long but earns its place because there is no output schema.

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 simple read tool with no annotations and no output schema, describing the returned fields covers the largest gap. However, the two required parameters remain completely unexplained, which is the main missing piece for correct invocation.

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 0% and both required parameters (device_id, zone_id) are bare strings. The description never explains what these identifiers are, where to obtain them, or that zone_id is scoped to device_id, so it fails to compensate for the coverage gap.

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?

Specific verb+resource ('Get full details of one zone') and it enumerates the returned facets (paths, nozzle angles, water amounts, bottle/fertilizer state, scheduling). The singular 'one zone' implicitly separates it from list_zones, but no sibling is named 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 only implied: 'one zone' suggests single-zone retrieval versus list_zones for enumeration, but there is no explicit when-to-use statement, no mention of alternatives like get_device_status, and no prerequisites (e.g., needing a valid zone_id).

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