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

No annotations, so description carries full burden. It transparently describes the combination of data sources, the two detail levels, units format with examples, and primary location fallback. No side effects or auth needs implied, which is consistent with a read-only briefing 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?

Well-structured, starting with purpose then block of details. Slightly long but each sentence adds value. Could be tightened, but not verbose.

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 tool with 4 parameters, no annotations, and an existing output schema, the description covers inputs, behavior, usage guidelines, and parameter semantics thoroughly. No gaps identified.

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%, but description adds rich meaning: explains 'detail' parameter options ('standard' vs 'full' with specific inclusions), units format with examples and allowed fields, and lat/lon omission behavior. None of this is in the schema.

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 'Get a comprehensive weather briefing for a US location' and distinguishes itself from sibling tools by positioning as the default for 'What's the weather?', combining conditions, forecast, alerts, and SPC outlook.

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?

Explains when to use as default and details for 'standard' vs 'full' detail levels. Mentions omitting lat/lon for primary location. Does not explicitly state when not to use or suggest specific sibling alternatives, but context signals provide sibling names.

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