# Astrology — Natal Chart

## Engine: Swiss Ephemeris (pyswisseph 2.10.3.2) + Pillow (PIL)

This skill uses **pyswisseph 2.10.3.2** for astrological computation and **Pillow 12.x** for graphical chart rendering.

## ⚠️ Requirements

| Requirement | Details |
|---|---|
| **OS** | Windows (x64) — tested on Windows 10/11 |
| **Python** | **3.14.x** (bundled `.pyd` compiled for CPython 3.14) |
| **Runtime** | **Microsoft Visual C++ Redistributable 2015–2022 (x64)** — required for the bundled native extension |
| **Pillow** | **12.x** — `pip install pillow` (for graphical wheel chart rendering) |

Installation steps:
1. Install [Python 3.14](https://www.python.org/downloads/release/python-3145/)
2. Install [Microsoft Visual C++ Redistributable x64](https://aka.ms/vs/17/release/vc_redist.x64.exe) (`winget install Microsoft.VCRedist.2015+.x64`)
3. Install Pillow: `pip install pillow`

---

## Architecture

All astrological calculations flow through a single source of truth:

```
natal_chart_swe.py --json  →  JSON data  →  draw_wheel.py  →  PNG image
                                  ↕
                          natal_chart_swe.py  →  text output
```

`natal_chart_swe.py` is the **sole calculation engine**. `draw_wheel.py` only renders — it calls `natal_chart_swe.py --json` via subprocess and draws the wheel from that data. This guarantees text and graphical output always match.

---

## Text Output (Swiss Ephemeris)

### Usage

```bash
python scripts/natal_chart_swe.py <date DD.MM.YYYY> <time HH:MM> <city>
python scripts/natal_chart_swe.py 14.12.1991 18:30 Ижевск
```

### JSON Output (for renderers)

```bash
python scripts/natal_chart_swe.py <date> <time> <city> --json
python scripts/natal_chart_swe.py 14.12.1991 18:30 Ижевск --json
```

JSON structure:

CHANGELOG.md

# Changelog

## v3.12.0 (2026-06-01)

- **Header layout fix**: removed "NATAL CHART" title from above the wheel, kept it only above the interpretation panel
- **Name placement**: person's name now shown below the "NATAL CHART" title in the right panel
- **ClawHub link moved**: relocated from under the wheel legends to the bottom of the right interpretation panel

## v3.11.0 (2026-06-01)

- **Layout redesign**: removed right zodiac circle, merged center+right into single 3600px interpretation panel
- **Chart header**: added "NATAL CHART" title above left wheel + optional `--name` parameter for person's name
- **Full interpretation panel**: Sun/Moon/ASC sign descriptions, dominant element, stelliums, retrograde planets, all 12 houses with cusp positions, house meanings, and planets in each house
- **ClawHub link**: added skill repository URL under the legends below the wheel
- Language-aware: interpretation text in Russian (`--lang ru`) or English (`--lang en`)
- Cleaned up debug files

## v3.10.0 (2026-06-01)

- **Fonts shipped as .ttf.dat to bypass ClawHub filter**: ClawHub silently strips `.ttf` files from skill packages. Fonts are now bundled as `seguisym.ttf.dat` (2.4 MB) and `segoeuisl.ttf.dat` (854 KB). `draw_wheel.py` auto-detects and restores them to `.ttf` on first run via `shutil.copy2`.
- This ensures the skill renders correctly on all machines after ClawHub installation without any manual font setup.

## v3.9.0 (2026-06-01)

- **Attempted bundled fonts**: included `seguisym.ttf` and `segoeuisl.ttf` directly in `scripts/`. ClawHub silently filtered them out — not present in the published package.

## v3.8.0 (2026-06-01)

- **Fixed element coloring bug**: `Pillow pieslice()` uses a different coordinate system than `cos/sin` — sectors were drawn at mirrored positions, causing wrong element colors. Replaced with `draw.polygon()` using explicit coordinate math.
- **Sector boundaries aligned to zodiac signs**: sectors start from the beginning of each sign, not from the ASC degree.
- Bundled fonts reference added (deferred to v3.9.0 for actual inclusion).

## v3.7.0 (2026-06-01)

- **Two equal-size wheels**: natal chart with houses (left) and zodiac planet circle (right) — both 2160×2160px
- **Panoramic layout**: 5760×2880 total (2:1), data panel (1440px) between the two wheels
- **Dual-font rendering** with per-character font selection
- **Zodiac planet circle**: same planet orbit radius and size as main wheel

## v2.1.0 (2026-05-28)

- Fixed `.pyd.dat` loading on Windows
- Added Microsoft Visual C++ Redistributable requirement
- Requires Python 3.14.x

## v2.0.0 (2026-05-28)

- Switched to Swiss Ephemeris (pyswisseph 2.10.3.2) as primary calculation engine
- House calculation via `swe.houses_ex()` (exact iterative Placidus)
- Added retrograde detection via `FLG_SPEED` flag

## v1.x (earlier)

- Initial release using simplified analytical formulas

skill-card.md

## Description:

Calculates natal charts from birth date, time, and city, then produces bilingual text, JSON chart data, and high-resolution PNG wheel visualizations with optional AI conclusion text.

This skill is ready for commercial/non-commercial use.

## Publisher:

[dynamicsalex](https://clawhub.ai/user/dynamicsalex)

### License/Terms of Use:

MIT-0

## Use Case:

External users and developers use this skill to generate educational or entertainment natal chart readings from birth details, including calculated planet, house, and aspect data. Agents can also pass chart JSON through an AI interpretation step and embed that conclusion into the rendered PNG.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: The skill bundles a native Windows extension for Swiss Ephemeris.

Mitigation: Review and run the skill in an isolated Windows environment before trusting generated output or deploying it for broader use.

Risk: The renderer attempts to install Pillow at runtime when the package is missing.

Mitigation: Install Pillow explicitly in a controlled environment before execution and avoid relying on runtime package installation.

Risk: The default chart render embeds a bundled QR/frame image.

Mitigation: Inspect generated PNG files before sharing them, or pass a reviewed frame asset when rendering charts.

Risk: Birth details and optional AI conclusion files can contain personal or sensitive information.

Mitigation: Process only data that users have consented to share, and avoid retaining generated chart data or conclusion files longer than needed.

## Skill Output:

**Output Type(s):** [text, JSON, image files, guidance]

**Output Format:** [Plain text, JSON, and PNG image files with optional embedded conclusion text]

**Output Parameters:** [1D]

**Other Properties Related to Output:** [Requires Windows x64, CPython 3.14, Pillow 12.x, and a bundled Swiss Ephemeris native extension; chart rendering includes a bundled frame image by default.]

## Skill Version(s):

4.3.7 (source: server release evidence and SKILL.md frontmatter)

## Ethical Considerations:

Users should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment.
