Savings Tips

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is clear. The description adds the example request body showing it uses birth data, which is useful. However, it does not describe what the output looks like or how recommendations are generated.

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 short and to the point, with only two sentences and an example. It is well-structured and front-loaded with the key phrase. However, it could be slightly more informative without losing conciseness.

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 that this is an astrological savings tool with 7 parameters and no output schema, the description does not explain what the tool returns, how it uses the elements, or what 'saving recommendations' means. It is incomplete for an agent to understand if it should be called.

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 100%, so all parameters are documented in the schema. The description does not add additional meaning beyond the schema, only provides an example. Baseline score of 3 is appropriate.

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 'Element-based saving recommendations' combined with the title 'Savings Tips' and the example request body indicates it provides savings advice based on astrological elements. It distinguishes from sibling financial tools by specifying 'element-based', but could be more explicit about its astrological nature.

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 is provided on when to use this tool versus other financial tools like financial_lucky_day or financial_wealth_house. The description lacks any context for selection.

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