Input Schema

Name	Required	Description
`name`	No
`seed`	No
`year`	No
`chart`	No	Birth data for a single natal chart. Required: date (YYYY-MM-DD), time (HH:mm:ss), latitude and longitude in decimal degrees. The short forms lat, lon, lng and tz are rejected with 400 INVALID_FIELD; pass the full names. timezoneOffset is hours from UTC and defaults to 0, meaning UTC; send timezone instead (an IANA name such as Europe/Kyiv, or auto) and the offset for that date is worked out, summer time included. city is a display label only: nothing here geocodes it, so it never stands in for coordinates. houseSystem is a single house-system letter, P by default; a name such as "Placidus" is refused, and the case matters because I and i are two different Sunshine systems.
`depth`	No	`extended` (10000 credits) adds the chart wheel and a chapter for each of Sun to Pluto, Chiron and the Ascendant in its sign, from edited texts with no AI at request time. Available in the 20 languages of `/v1/natal-texts`.
`chart1`	No	Birth data for a single natal chart. Required: date (YYYY-MM-DD), time (HH:mm:ss), latitude and longitude in decimal degrees. The short forms lat, lon, lng and tz are rejected with 400 INVALID_FIELD; pass the full names. timezoneOffset is hours from UTC and defaults to 0, meaning UTC; send timezone instead (an IANA name such as Europe/Kyiv, or auto) and the offset for that date is worked out, summer time included. city is a display label only: nothing here geocodes it, so it never stands in for coordinates. houseSystem is a single house-system letter, P by default; a name such as "Placidus" is refused, and the case matters because I and i are two different Sunshine systems.
`chart2`	No	Birth data for a single natal chart. Required: date (YYYY-MM-DD), time (HH:mm:ss), latitude and longitude in decimal degrees. The short forms lat, lon, lng and tz are rejected with 400 INVALID_FIELD; pass the full names. timezoneOffset is hours from UTC and defaults to 0, meaning UTC; send timezone instead (an IANA name such as Europe/Kyiv, or auto) and the offset for that date is worked out, summer time included. city is a display label only: nothing here geocodes it, so it never stands in for coordinates. houseSystem is a single house-system letter, P by default; a name such as "Placidus" is refused, and the case matters because I and i are two different Sunshine systems.
`format`	No	`pdf` (default) stores a PDF and answers with its `url`. `html` returns one self-contained `text/html` document, `markdown` returns `text/markdown` with the same sections and tables; neither is stored. Same price in every format.
`spread`	No
`language`	No
`whitelabel`	No
`report_type`	Yes
`allowReversed`	No

Output Schema

A4/5.0

Behavior3/5

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

The annotations already declare the safety profile: readOnlyHint=false, destructiveHint=false, openWorldHint=true, idempotentHint=false. The description adds useful cost and endpoint context, but does not explain non-idempotency, storage behavior, or other side effects beyond what annotations and the format/depth schema fields already cover.

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

Conciseness5/5

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

The description is compact and front-loaded: it opens with the dispatcher purpose, then lists the type values, then states the conditional input rules. The bracketed metadata is dense but useful, and there is no wasted prose.

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 13-parameter dispatcher, the description gives the essential type mapping and conditional required fields, while the output schema covers return values and annotations cover safety. A note on how renderer-specific unsupported fields are handled and on the optional parameters would make it fully complete, but the current definition is adequate.

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 description coverage is only 38%, so the description must compensate. It does add important meaning by mapping report_type values to conditional required inputs (chart, chart1+chart2, seed), but it leaves many optional parameters such as language, format, whitelabel, allowReversed, spread, year, and name unaddressed.

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 a specific verb and resource: 'Single endpoint over the 12 type-specific renderers,' and enumerates every report_type. It clearly distinguishes this dispatcher from the individual type-specific renderer siblings without requiring the schema to be opened.

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

Usage Guidelines4/5

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

It explains the main usage rationale — one method instead of 12 — and gives conditional input requirements: chart for most, chart1+chart2 for synastry, seed for tarot with chart optional. It stops short of explicitly saying when to prefer this dispatcher over the individual renderer tools or when to avoid it.

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