Generate Relocation Report (PDF or HTML)

astroway_reports_relocation

Compare up to five places for one birth chart as a multi-page A4 PDF (default) or live HTML (add ?format=html). Per place: the relocated ascendant and midheaven with the signed shift from birth, which planets changed house (the substantive difference, diffed rather than left as two tables), every astrocartography line running within 300 km with its interpretation text, and supportive/challenging scores across the 19 life categories. With more than one place a side-by-side comparison leads the document.

[Group: Reports] [Endpoint: POST /v1/reports/relocation] [Required: chart, locations] [Cost: 5,000 credits (Tier 7)] ⚠️ Premium — ~50% of free monthly budget. Confirm with user before invoking.

Input Schema

Name	Required	Description
`chart`	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.
`orbKm`	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.
`format`	No	`pdf` (default) stores a PDF and answers with its `url`. `html` returns one self-contained `text/html` document, `markdown` returns `text/markdown` with the same sections and tables; neither is stored. Same price in every format.
`language`	No
`locations`	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.
`categories`	No
`whitelabel`	No

Output Schema

Name	Required	Description	Default
`url`	No

A3.9/5.0

Behavior4/5

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

Annotations already declare a non-read-only, open-world, non-idempotent, non-destructive operation; the description adds the information that actually matters beyond that: the credit price, the tier, the share of the free monthly budget, and a mandate to confirm with the user first. It also signals format-dependent persistence ('live HTML' vs stored PDF). It does not warn that repeat invocations are billed again (relevant given idempotentHint=false), which keeps it at 4.

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 purpose and format choice, then the per-place content, then the operational metadata block. Every sentence carries information, though the single long sentence with multiple parentheticals is dense and the embedded query-param notation is easy to misread as a schema detail.

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?

An output schema exists, so return values need no explanation, and the description covers the expensive-mutation risk, format options, location cap and document contents — enough to call it correctly. The remaining gap is the repeat-charge/idempotency implication and the mismatch between the stated 300 km window and the configurable `orbKm`.

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 coverage is only 44%, so the description carries more burden than baseline. It does add meaning for several parameters — the five-location cap, the format choice, the 300 km ACG line window, and the 19 life categories — but it omits `fields`, `precision`, `language`, `whitelabel` and `orbKm` entirely, and 'add ?format=html' plus 'within 300 km' sit awkwardly against a body `format` enum that also accepts `markdown` and an `orbKm` range up to 3000.

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?

States a specific verb and resource: 'Compare up to five places for one birth chart' rendered as a multi-page A4 PDF or HTML document, and enumerates exactly what each place section contains (relocated ASC/MC, house changes, ACG lines within 300 km, 19-category scores). That is far more specific than the title alone. It stops short of 5 because it never names the adjacent sibling (astroway_geo_relocation) that returns the raw relocation data without a document, so an agent must infer the report-vs-data distinction.

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?

Gives clear invocation context: default is PDF, HTML is requested via `?format=html`, and more than one location produces a leading side-by-side comparison. The cost block adds a real usage gate — '5,000 credits (Tier 7) … ~50% of free monthly budget. Confirm with user before invoking.' No explicit when-not or named alternative, so it sits at 4 rather than 5.

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