get_personal_lucky_hours

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

No annotations are provided, so the description carries the transparency burden. It discloses the computation approach (zodiac relations with the day's Yellow/Black Belt hours) and the output semantics (best_hours with 0-10 personal scores). It stops short of detailing return shape, but the read-only nature is reasonably implied by 'Returns.'

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 a single dense sentence that front-loads the core action, then follows with method and output. The bilingual gloss adds clarity without padding.

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?

With no output schema, the description helpfully identifies the return concept (best_hours with scores), which is important for a tool with this complexity. A bit more detail about the exact return shape would improve completeness, but the essential invocation and output are clear.

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 the schema already documents both parameters. The description reinforces the role of date and zodiac and adds output meaning, but it does not add parameter syntax or format details beyond what the schema provides.

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 uses a specific verb ('Rank') and a specific resource ('12 hours of a day for YOUR zodiac sign'), and it explains the underlying method (zodiac relations plus Yellow/Black Belt hours). This clearly distinguishes it from sibling tools like get_daily_horoscope or get_solar_terms.

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?

The phrase 'for YOUR zodiac sign' and 'personal lucky hours' provide clear context for when this tool is appropriate. It does not explicitly name alternative tools or state when not to use it, but the intended use case is unambiguous.

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