enable_rain_delay

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

No annotations are present, so the description must fully disclose behavioral traits. It states the effect ('pauses all scheduled watering'), but lacks details on whether it is destructive, if reversion is needed, or any error states. The parameter constraints are given but minimal.

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 description is two sentences followed by a concise bullet list for args. Every word serves a purpose, no redundancy. It is front-loaded with the core action.

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?

The tool is simple with two params, but given 11 siblings and no annotations, the description is minimal. It doesn't explain what happens if already enabled, error conditions, or differentiate strongly from 'disable_rain_delay'. Completeness is adequate but not thorough.

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 0%, so the description must add meaning. It explains device_id as 'Device ID from list_devices' and hours as 'Hours to delay (1-168, max 7 days).' This adds needed context and constraints beyond the schema types.

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 clearly states 'Enable rain delay (pauses all scheduled watering).' This is a specific verb ('enable') on a resource ('rain delay'), and it distinguishes from the sibling 'disable_rain_delay' by name and action.

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?

No explicit when-to-use or when-not-to-use guidance is provided. While the name implies usage during rain to pause watering, there is no mention of alternatives or prerequisites. Usage is implied but not directly stated.

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