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.

TDQS

C2/5.0

Behavior3/5

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

Annotations already communicate read-only, idempotent, non-destructive behavior. The description adds useful operational context in the form of required inputs, endpoint, and a 10-credit Tier 1 cost, but it does not explain what the analysis computes or how the result should be interpreted.

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 description is short and front-loaded, but the only substantive sentence is vague and functions more as a title restatement than an explanation. The bracketed metadata lines are compact and useful for logistics, but the core purpose text is under-specified.

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?

This is a complex 15-parameter Hellenistic analysis endpoint, and the description does not explain what the qualities/quantities analysis produces or what tradition-specific concepts it applies. An output schema exists, so return-value details are less critical, but the domain purpose remains largely undocumented.

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

Parameters1/5

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

Schema description coverage is only 33% across 15 parameters, and the description adds no semantic meaning beyond repeating the four required parameters already enforced by the schema. Parameters such as zodiacType, houseSystem, cosmogram, and ayanamsaId receive no explanation from either the description or fully documented schema fields.

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 'Qualitative + quantitative analysis,' which restates the title without naming the specific Hellenistic/Schmidt resource or what is being analyzed. It does not differentiate this tool from sibling Schmidt or Hellenistic tools such as astroway_hels_qualities_and_quantities.

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 exclusions, and no mention of alternative tools. The bracket metadata lists required inputs and cost but does not tell an agent when this analysis is appropriate versus other Schmidt or Hellenistic endpoints.

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