RWS — Court Card Cross-Sum

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

Annotations already provide readOnlyHint=true, destructiveHint=false, idempotentHint=true, covering basic safety. The description adds minimal behavioral context beyond 'Birth-card meditation pair', not explaining what gets computed or returned. With annotations present, a 3 is appropriate—it adds some value but is not rich.

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 extremely concise, with only two lines and an example. Every element (purpose, group, example) earns its place. No unnecessary words.

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 the complexity and lack of output schema, the description should explain what the tool returns. It only says 'Birth-card meditation pair', which is insufficient. It does not help differentiate from similar sibling tools like tarot_rider_waite_birth_card, leading to contextual gaps.

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 descriptions cover 100% of parameters, so baseline is 3. The description provides an example request body but does not add meaning beyond the schema. The vague schema description for location parameters is not clarified in the description.

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 states 'Birth-card meditation pair for court-card practice' which hints at the purpose but is vague. The title 'Court Card Cross-Sum' adds some clarity, but it does not clearly distinguish from sibling tools like tarot_rider_waite_birth_card. A specific verb+resource is missing, making it less clear for an AI agent.

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 guidance on when to use this tool versus alternatives. No mention of context, exclusions, or when not to use it. The description lacks any usage guidance, relying solely on the name and group tag.

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