asktian_daily_reading

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

No annotations provided, so description carries full burden. Discloses return values and methodology (bazi + daily energy). Does not mention side effects (none expected) or permissions, but is sufficient for a read-like tool.

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 efficient paragraph, front-loaded with purpose. Slightly repetitive but no superfluous content.

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 low complexity and no output schema, description adequately covers what the tool does, returns, and when to use. Missing exact return format but understandable from listing.

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%. Description adds no extra parameter meaning beyond what schema already provides (e.g., defaults, enum options). 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?

Clearly states it provides a personalized daily reading based on Chinese metaphysics, listing specific outputs (archetype, energy, colors, etc.). Differentiates from siblings like asktian_today_energy by emphasizing personalization via birthdate.

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?

Explicitly gives use cases: 'when the user asks how today will be for them, what colors to wear, where to face their desk, or for general daily guidance.' No exclusion criteria but clear context.

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