Natal chart (kundli)

get_chart
Read-onlyIdempotent

Use this when the user wants their birth chart (kundli): ascendant, planets in signs and houses, yogas, the current planetary periods, or a divisional chart such as the navāṁśa (D9). Sidereal (Lahiri) chart: ascendant, the nine grahas, twelve houses, yogas and the Vimśottarī daśā. A modern Western block is added unless western is false. With location, also astrocartography lines at that place and the chart's own frame relocated there. Includes the D9 and D10 divisional charts by default; ask for any of the sixteen ṣoḍaśavarga with divisionals. Cost: 1 credit per call (only successful calls are charged; a sandbox key is free and returns a fixed sample). Deterministic: the same input always gives the same answer. Example arguments: {"birthData":{"date":"1990-05-12","time":"14:35","timezone":"Asia/Kolkata","latitude":28.6139,"longitude":77.209}}

Input Schema

NameRequiredDescriptionDefault
westernNoSet false to omit the modern Western block.
locationNoBoth coordinates or neither: a half-filled location is refused, never defaulted.
birthDataYesThe person's birth data: date, local time (omit if unknown), IANA timezone, latitude and longitude.
divisionalsNoDivisional charts (vargas) to include: any of the sixteen ṣoḍaśavarga. Default d9 (navāṁśa) and d10 (daśāṁśa); send [] for none. Each returns its ascendant and every graha's sign, degree and house within the varga, by the Parāśari formulas.
includeDashaNoInclude the Vimśottarī daśā periods in the chart response. Default true.

  5. First observed

TDQS

A4.6/5.0
Behavior5/5

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

Beyond the read-only and idempotent annotations, it discloses cost (1 credit per successful call), sandbox behavior, determinism, default inclusion of D9/D10, and the effect of passing `location` or omitting birth time. These are meaningful behavioral traits that help an agent predict billing and output shape.

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 definition is front-loaded with the usage trigger and is dense with useful details, but the first two sentences partially repeat the same chart components. It remains efficient overall because cost, determinism, defaults, and the example each add value.

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?

For a nested, multi-parameter chart tool with an output schema, the description covers the essential context: what is returned, defaults, location behavior, unknown-time behavior, billing, determinism, and an example. Nothing critical for correct invocation is missing.

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

Parameters4/5

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

Schema coverage is 100%, so the schema already documents most parameters, but the description adds practical meaning: `western: false` omits the modern block, `location` triggers astrocartography and relocation, and `divisionals` controls which vargas are returned. It also supplies a complete example argument for `birthData`.

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 opens with a specific usage trigger and resource: the user's birth chart (kundli), then enumerates exactly what is returned, including ascendant, grahas, houses, yogas, periods, and divisional charts. It distinguishes the tool from sibling ephemeris and compatibility tools by anchoring it to the natal-chart use case.

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

Usage Guidelines4/5

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

It clearly states when to use the tool: when the user wants their birth chart or specific natal components such as yogas or D9. It also explains conditional behavior for `location`, `western`, and `divisionals`, though it does not explicitly say when to prefer sibling tools like `get_dasha` for standalone period queries.

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