Input Schema

Name	Required	Description
`date`	Yes
`time`	No
`fields`	No	Compact mode: comma-separated dotted paths to keep, relative to `data`, e.g. "planets.name,planets.longitude,houses.cusp". Omit for the whole response.
`timezone`	No	IANA zone name such as Europe/Kyiv, or auto to look the zone up from latitude and longitude. The server takes the offset that zone kept at this local date and time, summer time included, and uses it in place of timezoneOffset. A clock time that happened twice takes the first occurrence; one skipped when clocks went forward takes the offset from before the change. Abbreviations such as EST are refused. Before 1970 the tz database is not reliable for every place, so send timezoneOffset when the local clock is known.
`precision`	No	Compact mode: round fractional numbers to this many decimals. Longitudes carry 14 by default; 2 is finer than any chart is drawn.
`timezoneOffset`	No	Ignored when timezone is sent.

Output Schema

Name	Required	Description	Default
`notes`	No
`animal`	No
`palaces`	No
`solarYear`	No
`disclaimer`	No
`yearPillar`	No

TDQS

A4.5/5.0

Behavior5/5

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

Beyond the readOnly/idempotent annotations it discloses two behaviors an agent could not infer: the response is degenerate (same for every birth date) and the call costs 5 credits. The deprecation and sunset dates also signal that the tool may disappear, which is exactly the context annotations cannot carry.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The deprecation warning and the 'identical for every birth date' caveat are front-loaded, which is the right ordering, and the whole thing is three short sentences. The bracketed metadata block partly repeats schema facts ([Required: date]) but the endpoint and cost lines earn their place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a low-complexity, deprecated tool with an output schema and full annotations, the description covers the decision-relevant facts: it is useless for real charting, it costs credits, and where to go instead. Only the runtime behavior of calling a deprecated endpoint is left unspecified.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is moderate (67%) and the schema already documents fields, precision, timezone and timezoneOffset in detail; the description only repeats 'Required: date' and adds nothing about the undocumented time parameter or how parameters interact with the degenerate output. Baseline 3 is appropriate since the schema does the semantic work.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states concretely what the tool returns (year pillar, animal, a 12-palace overview) and, crucially, that the output is identical for every birth date, so an agent knows this is not a real chart. It also names the replacement path so it is immediately distinguishable from astroway_ziwei_chart and the individual palace tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives an explicit when-not-to-use (deprecated, sunset date) and a concrete alternative (POST /ziwei/chart, which actually places the stars). An agent reading only this text knows to route the request elsewhere.

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