plan_weekend_getaway

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

Annotations already indicate readOnly, idempotent, openWorld. Description adds critical behavioral detail: it requires payment via x402 and can return live server output or x402 metadata. This goes beyond the annotations and is valuable for agent decision-making.

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?

Three sentences front-load purpose and usage. No fluff, but could be slightly more direct about parameter expectations. Still efficient.

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?

Given 12 parameters, no output schema, and no parameter descriptions, the description covers purpose and usage context but leaves significant gaps about input specifics and expected output format.

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% with 12 parameters all optional. The description mentions some concepts (lodging, water/weather, transportation) that loosely map to parameters but provides no explicit semantic meaning or format guidance for any parameter.

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 the tool connects to a paid weekend-getaway service for short overnight escapes. It distinguishes from siblings like plan_day_trip by specifying it's for weekend getaways. However, the phrasing 'live paid x402 weekend-getaway service' is slightly opaque.

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?

Provides usage context: 'Use when the traveler wants a calmer planning brief with lodging, water/weather, transportation, and backup ideas.' It also mentions payment via x402. But it does not explicitly state when not to use or compare to siblings.

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