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.
`withTnp`	No
`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
`orb`	No

TDQS

C2.6/5.0

Behavior3/5

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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so safety is covered. The description adds genuinely useful operational context — the POST endpoint and a concrete cost of 10 credits (Tier 1) — but says nothing about what the computation produces or how the optional switches change behavior.

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?

It is short and front-loads the one descriptive line, and the bracketed metadata is scannable. However, five words of actual description for a 16-parameter astrological computation is under-specification rather than effective conciseness.

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?

An output schema exists, so return values need not be explained, and annotations cover safety. Against that, a 16-parameter tool with three enums and low schema coverage needs at least a note on how the required inputs and the TNP/cosmogram/house-system options shape the result, and the description provides none.

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 31% across 16 parameters, so the description is expected to compensate and does not. It merely repeats the four required fields already listed in the schema's required array and leaves undocumented options like withTnp, cosmogram, houseSystem, zodiacType, and ayanamsaId with no explanation of their effect on midpoint hits.

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

Purpose3/5

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

The phrase 'Ebertin's personal points midpoint hits' names a specific technique but is jargon that doesn't state plainly what the tool returns (a list of sensitive/midpoint hits?). It does not differentiate itself from close siblings such as astroway_cosmobiology_personal_point_tree, midpoint_pictures, or transit_midpoints, so an agent cannot tell which one to pick from the text alone.

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

Usage Guidelines2/5

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

There is no when-to-use or when-not-to-use guidance and no mention of the sibling tools that overlap in scope. The only contextual hints are the group/endpoint/required-parameter tags, which do not tell an agent when this technique is the right choice.

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