Dashas: Dwadashottari Sookshmadasha

astroway_vedic_dashas_dwadashottari_sookshma

Read-onlyIdempotent

Dwadashottari Sookshmadasha: the 8 sub-periods of the running period at targetDate, 4 levels deep, split in proportion to the lords' years from the period's own lord. Inside the birth mahadasha the split follows the full period from its notional start: sub-periods that ended before birth are left out and the running one starts at birth.

Input Schema

Name	Required	Description
`body`	Yes	Birth data for a single natal chart. Required: date (YYYY-MM-DD), time (HH:mm:ss), latitude and longitude in decimal degrees. The short forms lat, lon, lng and tz are rejected with 400 INVALID_FIELD; pass the full names. timezoneOffset is hours from UTC and defaults to 0, meaning UTC; send timezone instead (an IANA name such as Europe/Kyiv, or auto) and the offset for that date is worked out, summer time included. city is a display label only: nothing here geocodes it, so it never stands in for coordinates. houseSystem is a single house-system letter, P by default; a name such as "Placidus" is refused, and the case matters because I and i are two different Sunshine systems.
`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.
`precision`	No	Compact mode: round fractional numbers to this many decimals. Longitudes carry 14 by default; 2 is finer than any chart is drawn.

A3.5/5.0

Behavior4/5

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

The annotations already establish the read-only, idempotent, non-destructive profile, and the description adds useful behavioral context: the proportional splitting rule, the treatment of sub-periods before birth, and the 20-credit cost tier. It does not describe response structure, but an output schema exists to cover that.

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 compact and front-loads the core definition, followed by the important birth-mahadasha edge case and structured metadata tags. The second sentence is dense but earns its place by clarifying non-obvious behavior.

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?

For a complex Vedic dasha tool with a rich input schema, full schema coverage, annotations, and an output schema, the description covers the essential calculation semantics and an important birth-time edge case. The main remaining gap is the lack of explicit routing guidance relative to sibling dasha-level tools.

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 the schema already documents the three parameters thoroughly. The description adds meaning to `targetDate` by tying it to the running period, and references the birth mahadasha context, but it does not explain `fields` or `precision` beyond what the schema provides.

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

Purpose4/5

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

The description clearly states the resource: the Dwadashottari Sookshma sub-periods of the running period at `targetDate`, four levels deep with eight sub-periods. This is specific enough to distinguish the sookshma level from shallower dasha levels, though it does not explicitly name sibling tools such as the pratyantar or prana endpoints.

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?

The description explains the mechanics of the calculation but gives no explicit guidance on when to choose this tool over sibling dasha-level tools. An agent must infer that it should be used when four-level Dwadashottari sub-period detail is needed.

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