Input Schema

Name	Required	Description	Default
`at`	No	moment (default): tithi, nakshatra, yoga and karana at date + time. sunrise: at local sunrise of that date, as a printed panchang gives them; time may be omitted.
`city`	No
`date`	Yes
`name`	No
`time`	No
`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.

A3.9/5.0

Behavior4/5

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

Annotations already declare readOnlyHint/idempotentHint/destructiveHint=false, so safety is covered. The description adds real non-obvious behavior: `endsAt` semantics, the sunrise-referenced moonrise/moonset convention ('disc centre on the horizon as panchangs count it') and the null rule when the Moon does not rise/set within 30 hours. It stops short of stating computation basis (ayanamsa default, zodiac) which matters for a sidereal panchang.

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?

Front-loaded with the component inventory, then moves to time/return semantics in dense but economical sentences; no filler prose. The trailing [Group]/[Endpoint]/[Required]/[Cost] block is boilerplate but does add transport and cost facts that are otherwise unavailable.

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

Completeness5/5

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

An output schema exists, yet the description still supplies the interpretive details an agent needs to read the response correctly (endsAt offsets, null conditions, muhurta list shapes). Combined with the cost/endpoint block, an agent has enough to call this correctly.

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 38% across 16 parameters, so the description is expected to compensate but addresses no parameter at all — it never mentions date/time, latitude/longitude, the `at` moment-vs-sunrise switch, timezone, ayanamsa or the `fields`/`precision` compact mode. The only thing close to parameter meaning is the sunrise timing convention, which is about output rather than inputs.

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?

States a specific resource (complete daily Panchang) and enumerates exactly which elements it returns (Tithi, Vara, Karana, Yoga, Nakshatra, Choghadia, Rahu Kaal, Yamaganda, Gulika, Abhijit Muhurat, muhurtas). This enumeration distinguishes it at a glance from the single-element siblings such as panchang_tithi, panchang_rahu_kaal and panchang_choghadia, which return just one component.

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?

Usage is implied rather than stated: 'Single call' plus the full component list signals this is the aggregate tool to pick when you want everything, and the granular siblings exist for single components. However, there is no explicit when-to-use / when-not sentence, no guidance on preferring a cheaper sibling, and no mention of the credit cost tradeoff (20 credits, Tier 2).

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