## What it does

The skill executes `skd-decompile.ps1` via PowerShell. It reads a 1C SKD layout from `Template.xml` and maps fields, parameters, variants, and templates into a JSON draft formatted for `skd-compile`. If `-OutputPath` is omitted, output goes directly to stdout.

The generated JSON is not a lossless representation. Any construct the tool cannot translate receives an `__unsupported__` sentinel tag, and every coordinate is logged into a companion `.warnings.md` file. The compiler will reject the schema until these nodes are manually rewritten or removed. Nested schemas and Picture cells cause the script to halt with a non-zero exit code.

This skill is not meant for minor adjustments. A full decompile-compile cycle rewrites the entire XML file and creates massive Git diffs, so small edits require `/skd-edit` instead.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add Nikolay-Shirokov/cc-1c-skills
```
In the agent chat (not a shell):
```text
/plugin install 1c-skills@cc-1c-skills
```
This installs the whole 1c-skills plugin with all its skills

2. **Skills CLI (Vercel)**
```bash
npx skills add Nikolay-Shirokov/cc-1c-skills --skill skd-decompile -a claude-code
```

3. **Manually: put the files in place**
- File: `~/.claude/skills/skd-decompile/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/skd-decompile/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Nikolay-Shirokov/cc-1c-skills --skill skd-decompile -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/skd-decompile/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/skd-decompile/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Nikolay-Shirokov/cc-1c-skills skd-decompile
```

2. **Manually: put the files in place**
- File: `.github/skills/skd-decompile/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/Nikolay-Shirokov/cc-1c-skills --path .claude/skills/skd-decompile
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/skd-decompile/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Nikolay-Shirokov/cc-1c-skills/tree/HEAD/.claude/skills/skd-decompile/SKILL.md

## When to use it
- decompile a 1C SKD Template.xml into a JSON structure
- scaffold a new report from an existing schema
- generate an editable draft for the skd-compile tool
- detect unsupported SKD elements before major refactoring

## Example prompts
- Decompile this report schema: `/skd-decompile src/Reports/Sales/Template.xml -OutputPath draft.json`
- Convert `Template.xml` to a JSON draft in stdout: `/skd-decompile Ext/Template.xml`
- Extract the SKD layout into a draft file: `/skd-decompile ./Template.xml -OutputPath report.json`

# /skd-decompile — JSON-черновик из Template.xml СКД

Читает Template.xml и эмитит JSON в формате `skd-compile`. **Результат — черновик**, а не обратимое представление: см. раздел «Что получаешь».

## Когда использовать

- **Scaffold нового отчёта по образцу** — взять существующий СКД, получить JSON, поправить и скомпилировать в новый.
- **Структурный рефакторинг** — переписать вариант, перерисовать шаблон, перебрать набор полей.

## Когда **не** использовать

- **Точечные правки готового отчёта** (добавить поле, фильтр, итог, переименовать) → `/skd-edit`. Цикл «декомпиляция → правка JSON → компиляция» переписывает шаблон целиком, может терять непокрытые конструкции и даёт большой diff в исходниках. `/skd-edit` правит адресно, без полной реконструкции.

## Параметры

| Параметр | Описание |
|----------|----------|
| `TemplatePath` | Путь к Template.xml (обязательный) |
| `OutputPath` | Путь к выходному JSON. Если не задан — JSON в stdout |

```powershell
powershell.exe -NoProfile -File "${CLAUDE_SKILL_DIR}/scripts/skd-decompile.ps1" -TemplatePath "<Template.xml>" -OutputPath "<out.json>"
```

## Что получаешь

JSON-черновик в формате `/skd-compile` — **не полное обратимое представление СКД**. На вход компилятору такой JSON напрямую может не пойти: в нём встречаются sentinel-узлы (маркер `__unsupported__`).

- **Готовые узлы** — большая часть СКД (поля, параметры, шаблоны, варианты со structure/filter/order/conditionalAppearance и т.п.) ложится в JSON как обычные узлы DSL.
