## Changes things (6)

Creates or changes something that can be changed back. Claude Code: ask.

### `post_vastu_ayadi`

- The name "post_vastu_ayadi" says "post": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Ayadi shadvarga calculator for a building or a room: send the dimensions and the API returns all six proportional formulas with the multiplier, the divisor and the remainder shown, the member each remainder names, and the two verdict rules the texts state. Choose between three text families, which genuinely disagree, and choose your own cubit length, because every remainder is unit sensitive. Built for practitioner tools, plan checking software and anyone who has to justify a dimension rather than assert it.
```

### `post_vastu_entrance`

- The name "post_vastu_entrance" says "post": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Vastu entrance analysis for a main door: send the plot and where the door sits, and the API returns which of the 32 perimeter padas it falls on, the devata of that square, the effect the classical chapter gives that pada, and the favourable padas on the same side to move toward. Every verdict carries the chapter and verse it comes from as a typed field, and the reading holds on either the 81 pada or the 64 pada division. Built for property and interior design tools, practitioner reports, and any product that has to say whether a front door is well placed.
```

### `post_vastu_mandala`

- The name "post_vastu_mandala" says "post": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Vastu Purusha Mandala projected over a real plot: send the ground and the API returns every square with the devata holding it, the brahmasthan as a polygon you can draw, the marma points, the six vamsa diagonals named by their devatas and the nine atimarma crossings. Choose the 81 pada Paramasayika or the 64 pada Manduka, and the response says which verses each part rests on. Built for floor plan overlays, practitioner reports and any tool that has to place rooms against the classical grid.
```

### `post_vastu_plot`

- The name "post_vastu_plot" says "post": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Vastu plot analysis from typed geometry: send the outline, the facing, where the ground falls and where the water is, and the API returns a verdict on the shape, the proportion, the ground level under two schools, each corner extension and cut, the road and the water. Every verdict names the chapter and verse behind it, or says plainly that it is convention, which matters because the ground level verses and the widely taught modern rule genuinely disagree. Built for listing and land assessment tools, practitioner site reports and buyer facing checks.
```

### `post_vastu_rooms`

- The name "post_vastu_rooms" says "post": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Vastu room direction check for a whole floor plan: send the plot and a list of rooms, by quarter or by outline, and the API returns a verdict per room with the quarters it belongs in, the quarters to keep it out of, a remedy when it is misplaced, and a composite score with the weights published. Four of the twelve room types carry a chapter and verse and the other eight are labelled convention, so a report can say which half of it is classical. Built for floor plan tools, listing checks and practitioner reports.
```

### `post_vastu_timing_griha_pravesh`

- The name "post_vastu_timing_griha_pravesh" says "post": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Griha pravesh muhurta search over a date window: send the window and the place, and the API returns every day that clears the classical day-level rules, with the nakshatra, tithi, weekday and solar position that qualified it and the rule ids that admitted it. Two Muhurta texts disagree on the admissible nakshatras and you choose which one leads, and the rules a date search cannot settle are published rather than dropped. Built for house warming date pickers, practitioner scheduling and agent assistants that have to answer when a family should move in.
```

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `get_vastu_devatas`

- The name "get_vastu_devatas" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Reference table of the 45 devatas of the Vastu Purusha Mandala: which squares of the 81 pada grid each one holds, which ring and which side, how many padas, and the verses that place it. A pure reference endpoint with no plot required, for building a mandala diagram or a glossary. Where the sources contradict each other, and they do on several rows, the row says so instead of quietly picking a side.
```

### `get_vastu_devatas_id`

- The name "get_vastu_devatas_id" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up one devata of the Vastu Purusha Mandala: the squares it holds, its ring and side, its pada count, the entrance pada it governs where it sits on the perimeter, and the verses that place it. Case and punctuation in the id are folded, so indra-outer, Indra_Outer and INDRA OUTER all resolve.
```

### `get_vastu_directions`

- The name "get_vastu_directions" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Reference table of the eight Vastu directions: the dikpala who rules each quarter of the horizon, the squares of the mandala it covers with their devatas, what the chapter places on that side, and what standing water there brings. A pure reference endpoint with no plot required, for building a picker or a directions guide. Every row says which verse each part comes from and labels the element as the later convention it is.
```

### `get_vastu_directions_id`

- The name "get_vastu_directions_id" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up one Vastu direction: its dikpala, the mandala squares it covers with their devatas, what the chapter places there, and what standing water in that quarter brings. Case and punctuation in the id are folded, so north-east, northeast and NorthEast all resolve to the same entry, and the id space is the one the feng shui and I Ching endpoints use.
```
