Daily horoscope by zodiac sign - Transit-based editorial columns

get_astrology_horoscope_sign_daily

Read-only

A publish-ready column for any zodiac sign, built from the dated transits over it and returned with those events for fact-checking. The reading names the aspects, sign ingresses, lunations and retrograde stations driving it and reads each into the whole-sign houses of that sign, so every sign gets different content rather than one blurb reused twelve times. Alongside the column come overview, love, career, health, finance and advice, the active transits, Moon sign and phase, an energy rating, lucky number and color, and compatible signs. No language model is involved, so a given sign and date always returns the same text and a piece scheduled months ahead is the piece that runs. Content rolls over at midnight, by default UTC. Pass date for editorial scheduling, or timezone to roll over on a local clock. Available in eight languages. Daily horoscope API, zodiac forecast, sun sign horoscope, astrology prediction.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`date`	No	Forecast date in YYYY-MM-DD format. Past and future dates are both supported, for editorial scheduling and backfill. Defaults to the current period in the timezone parameter.
`lang`	No	Response 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
`sign`	Yes	Zodiac sign, case-insensitive (e.g., aries, Aries, ARIES all work).
`compact`	No	Set 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.
`timezone`	No	Selects which period counts as current when date is omitted. Defaults to UTC, so the forecast rolls over at 00:00 UTC on each day. Pass the timezone of the end user to roll over on their local clock instead. Ignored when date is set. Accepts an IANA name (e.g. "America/New_York"), decimal hours (e.g. 5.5 for IST), or a fixed UTC offset (e.g. "-05:00").

TDQS

A4.4/5.0

Behavior5/5

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

Besides the readOnlyHint annotation, the description adds substantial behavioral detail: output is deterministic because no language model is involved, content rolls over at midnight by default UTC, and the same text is guaranteed for a given sign and date. It also discloses the fact-checking event list and language coverage, going far beyond 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 core sentences are information-dense and front-loaded, covering purpose, output, determinism, and scheduling behavior. The definition loses a point by trailing off into redundant SEO-style keywords such as Daily horoscope API, zodiac forecast, sun sign horoscope, and astrology prediction, which add no agent 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?

Despite having no output schema, the description thoroughly enumerates returned content: overview, love, career, health, finance, advice, active transits, Moon sign and phase, energy rating, lucky number and color, and compatible signs. It also explains timezone handling, deterministic scheduling for future dates, and language behavior, giving an agent enough context to invoke and interpret the result correctly.

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?

The schema already documents all five parameters with full descriptions, so the baseline is 3. The description reinforces the date and timezone semantics with editorial scheduling and local-clock rollover language, but it does not add meaningfully new parameter-level information beyond what the schema already provides.

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 concrete deliverable: a publish-ready column for any zodiac sign built from dated transits and returned with the underlying events for fact-checking. It clearly distinguishes the tool from weekly, monthly, and yearly sibling tools through the title, the daily rollover behavior, and its transit-based editorial approach.

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?

The description gives clear operational guidance for when to customize invocation, such as passing a date for editorial scheduling or a timezone to roll over on a local clock. It does not explicitly name alternative sibling tools or state when not to use this tool, so it falls short of full exclusion-based guidance.

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

A3.8/5.0

Disambiguation3/5

Most tools are scoped to a clearly distinct domain—moon phases, houses, returns, fixed stars, astrocartography—but several pairs overlap, notably synastry vs. compatibility_score and transits vs. transit_aspects. The descriptions are long and do help an agent choose, but the boundaries are not always obvious at the name level.

Naming Consistency4/5

Every tool follows the same snake_case get_astrology_/post_astrology_ prefix pattern, making the group predictable and readable. However, collection endpoints like get_astrology_planet_meanings_id and get_astrology_signs_id awkwardly combine plural collection and singular id naming, and names like calendar_year_month depart from the cleaner resource+suffix pattern.

Tool Count2/5

With 38 tools, this is well over the 25+ threshold and feels heavy for an agent to traverse. While Western astrology is a broad domain, several near-duplicate endpoints, especially synastry/compatibility and transits/transit_aspects, could be consolidated into fewer, more scoped tools.

Completeness5/5

The toolset is comprehensive, covering natal charts, relationships, transits, returns, progressions, aspects, houses, relocation, and reference data. It includes enough specialized endpoints for both casual horoscope use and in-depth astrological analysis, with no obvious dead ends for the stated domain.
