save_horoscope

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

No annotations provided, so description fully responsible for behavioral context. It does not disclose whether saves overwrite or append, any validation rules, error handling, or side effects of mutations.

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?

Description is relatively concise: a one-line summary followed by parameter list. Could be more compact, but the structure is clear and efficient for an 8-parameter tool.

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 8 parameters, 6 required, no output schema, and no annotations, the description provides parameter semantics but misses behavioral context, usage guidance, and output description. It does not fully compensate for the missing structured information.

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%, and description adds brief explanations for each parameter (e.g., 'Name of the person', 'Hour of birth (e.g., 14:30, Ngọ)'). This adds meaning beyond schema titles but lacks validation or formatting details.

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 saves birth chart details to a local database for retrieval. This verb+resource combination is distinct from siblings like delete, generate, get, and list.

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 guidance on when to use this tool versus alternatives (e.g., generate_horoscope). It only implies persistence but doesn't differentiate from other horoscope tools.

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