Input Schema

Name	Required	Description	Default
`city`	No
`date`	Yes
`name`	No
`time`	Yes
`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.
`ayanamsa`	No	Sidereal school by name. Lahiri when omitted. Equivalent to ayanamsaId; send either.
`latitude`	Yes
`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.
`cosmogram`	No
`longitude`	Yes
`precision`	No	Compact mode: round fractional numbers to this many decimals. Longitudes carry 14 by default; 2 is finer than any chart is drawn.
`ayanamsaId`	No
`zodiacType`	No
`houseSystem`	No		P
`timezoneOffset`	No	Hours from UTC at the given moment, not minutes. Fractional zones are hours too: 5.5 for India, 5.75 for Nepal, -3.5 for Newfoundland. Defaults to 0, meaning UTC. Ignored when timezone is sent.

Output Schema

Name	Required	Description	Default
`source`	No

TDQS

D1.9/5.0

Behavior2/5

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

Annotations already declare this is a read-only, idempotent, non-destructive operation, so the safety profile is covered. The description adds only endpoint, required inputs, and a 10-credit Tier 1 cost, which is useful but does not disclose what the tool actually computes or returns beyond the vague doctrine label.

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

Conciseness3/5

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

The text is short and front-loads the doctrine label, with bracketed metadata that is easy to scan. However, its brevity reflects under-specification rather than efficiency: the one substantive sentence does very little work, and the metadata repeats schema-level facts.

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

Completeness2/5

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

For a 15-parameter tool with a 33% schema coverage gap, the description is far too thin. The output schema and annotations reduce some burden, but the description still fails to explain the tool's computational purpose or how to choose among closely related Schmidt and Hellenistic alternatives.

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

Parameters2/5

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

Schema description coverage is only 33% across 15 parameters, so the description needs to compensate and does not. It merely repeats the four required parameters already marked required in the schema, while optional parameters such as fields, ayanamsa, zodiacType, houseSystem, and timezone receive no additional explanation.

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

Purpose2/5

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

The description says only 'Stoic doctrine of elemental natures,' which names a topic but not a specific computed result or action. It does not distinguish this tool from the near-identical sibling astroway_hels_stoic_elementhood or from other Schmidt Hellenistic tools, so an agent cannot confidently tell what it produces.

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

Usage Guidelines1/5

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

There is no when-to-use guidance, no when-not-to-use guidance, and no named alternative. The metadata lists required inputs and cost, but nothing tells an agent which situation calls for this tool versus the many other Hellenistic Schmidt calculators.

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