Includes inauspicious periods (Rahu Kaal, Yamaganda, Gulika Kaal) and auspicious windows (Abhijit Muhurta, Brahma Muhurta). Current planetary hora with start/end times. Essential for muhurta selection, daily horoscope apps, Hindu calendar integration, and electional astrology. Accurate calculations based on observer location.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
dateYesDate in YYYY-MM-DD format. A single-digit month or day is accepted and zero-padded (2026-3-5 becomes 2026-03-05). Impossible calendar dates are rejected.
langNoResponse language (BCP 47). Supported: en, tr, de, es, hi, pt, fr, ru, zh-Hans, zh-Hant. Defaults to en. Coverage varies by domain, and a field with no translation in the requested language returns English.en
compactNoSet true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens.
latitudeYesObserver latitude in decimal degrees. Determines sunrise and sunset times which define day/night boundaries for muhurta calculations.
timezoneNoTimezone: an IANA name (e.g. "America/New_York", "Europe/London", or `cities[0].timezone` from /location/search) or decimal hours from UTC (e.g. -5 for EST, 5.5 for IST). An IANA name is resolved to the offset in force at the given date and time. Send the timezone that matches the coordinates: sunrise, sunset and every muhurta boundary are found by searching forward from local midnight, so the default anchors the search to an Indian day. Omitting it for a location outside IST returns a correctly ordered set of periods for the wrong window, shifted by the difference between 5.5 and the real offset. Defaults to 5.5 (IST).
longitudeYesObserver longitude in decimal degrees. Affects local time calculations for sunrise, sunset, and muhurta period boundaries.

  9. First observed

TDQS

A3.7/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds the note 'Accurate calculations based on observer location,' which provides a minor behavioral hint about location dependence, but does not describe potential edge cases, rate limits, or response characteristics beyond the content list. It does not contradict the annotations.

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 description is a single paragraph of three sentences, front-loaded with the core content (five limbs and additional periods). It is efficient and avoids fluff, though the final sentence about accurate calculations is somewhat redundant given the schema. Overall, it is well-structured and earns its length.

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

Completeness4/5

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

Given the complexity of the tool (6 parameters, extensive output), the description provides a solid high-level overview of content and use cases. The presence of an output schema covers return details, and the parameter schema covers inputs thoroughly. The description does not mention the compact parameter or timezone nuances, but those are in the schema. It is sufficiently complete for an agent to understand the tool's purpose and call it correctly when combined with schema.

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

Parameters3/5

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

Schema description coverage is 100%, so all six parameters (date, lang, compact, latitude, timezone, longitude) are already thoroughly documented. The description only reinforces the role of observer location in calculations, which the schema already explains in detail. It adds minimal new meaning beyond the schema, justifying the baseline score of 3.

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?

The description clearly states the tool returns a complete daily panchang with all five limbs (Tithi, Nakshatra, Yoga, Karana, Vara) plus sunrise/sunset/moonrise/moonset times, inauspicious and auspicious periods, and planetary hora. It is specific about the resource and scope, and the word 'detailed' plus the enumerated components distinguish it from basic panchang tools, though it does not name siblings.

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 description mentions essential use cases (muhurta selection, daily horoscope apps, Hindu calendar integration, electional astrology) but does not explicitly contrast with sibling tools like panchang_basic, choghadiya, or hora. It gives implied context for when this detailed tool is appropriate but lacks explicit when-not-to-use or alternative selection guidance.

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