Input Schema

NameRequiredDescriptionDefault
cityNo
dateYes
nameNo
timeYes
fieldsNoCompact mode: comma-separated dotted paths to keep, relative to `data`, e.g. "planets.name,planets.longitude,houses.cusp". Omit for the whole response.
ayanamsaNoSidereal school by name. Lahiri when omitted. Equivalent to ayanamsaId; send either.
latitudeYes
timezoneNoIANA 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.
cosmogramNo
longitudeYes
precisionNoCompact mode: round fractional numbers to this many decimals. Longitudes carry 14 by default; 2 is finer than any chart is drawn.
ayanamsaIdNo
zodiacTypeNo
houseSystemNoP
timezoneOffsetNoHours 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.

  2. First observed

TDQS

C2.9/5.0
Behavior3/5

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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds genuinely non-obvious operational facts: the POST endpoint, the four mandatory inputs, and a cost of 10 credits at Tier 1. It does not describe what the tiers are, how many levels are returned, or whether the response depends on sect/house system choices.

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 bracketed metadata block is tightly formatted and front-loads group, endpoint, required inputs, and cost in four short lines with no filler. Its brevity is efficient, though the opening sentence carries almost no information relative to the space it occupies.

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 15-parameter, tradition-specific astrological computation with a rich output schema, and the description supplies only routing metadata plus the required field list. An agent still cannot tell what the returned 'causation tiers' contain, how many there are, or how optional settings alter the result, which is a substantial gap even allowing that the output schema covers return shape.

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?

With 15 parameters and only 33% schema description coverage, the description is expected to compensate, but it only repeats the four required fields that the schema already marks required. Nothing is said about the meaningfully ambiguous optional inputs (ayanamsa vs ayanamsaId, zodiacType, houseSystem, fields/precision compact mode, timezone vs timezoneOffset) that a caller must get right for this tradition-specific calculation.

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 description reduces to 'Schmidt's causation tiers', which is essentially a restatement of the tool name/title rather than a statement of what the call computes or returns. The group tag and endpoint line do place it in the Hellenistic/Schmidt family, so an agent can locate it among siblings, but it never says what a 'level of causation' output actually is.

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

Usage Guidelines3/5

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

The alias note explicitly states this is a cursor-friendly duplicate of `astroway_hellenistic_schmidt_levels_of_causation`, which usefully tells an agent not to call both. There is no guidance on when causation-tier analysis is the right request versus the other Schmidt endpoints (sect classes, stations and phases, qualities and quantities), so selection among siblings is still guesswork.

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