check_auspicious_date

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

No annotations provided, so description needed to disclose behavior. It mentions 'traditional Chinese calendar principles' but lacks specifics about data sources, determinism, limitations, or what happens on invalid dates. The output description is good but behavioral traits are vague.

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?

Single sentence covering purpose, inputs, and outputs efficiently. No wasted words, but could be slightly more structured by splitting output details.

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 no output schema, the description adequately explains return values (score, level, analysis). Mentions cultural factors and activity suitability. Lacks error handling or edge case descriptions, but sufficient for typical use.

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 100%, so the schema already documents parameters. Description adds minimal extra meaning beyond what schema provides, such as listing example activities (wedding, business_opening). Baseline 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?

Clearly states the tool analyzes a date for auspiciousness based on traditional Chinese calendar principles, and specifies output format including score, level, and analysis. Distinguishes itself from siblings like find_good_dates or batch_check_dates by focusing on a single date with a specific activity.

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?

Implies usage for single-date activity analysis, but does not explicitly state when to use this tool versus siblings like find_good_dates or batch_check_dates. No when-not-to-use guidance or alternatives mentioned.

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