# meta-decompile

Reads a 1C metadata object XML and emits a compact JSON draft in the meta-compile format. Useful when a new object is easier to build from an existing one than to write from scratch.

## What it does

The skill parses XML such as `Catalogs/Name.xml` and emits a JSON draft for `/meta-compile`. Structure and properties go in. UUIDs, module bodies, forms, templates and rights do not.

That makes it a one-way tool. A compiled draft produces a new object with a fresh identity, so every reference to the source object — from code, other objects, subsystem contents, predefined data — breaks. Never compile a draft over the source object and never pass it off as a reimport.

It runs through `scripts/meta-decompile.ps1` under PowerShell. The object XML path is required; `OutputPath` is optional, and without it the JSON goes to stdout. An unsupported object type or a root that is not `MetaDataObject` returns a non-zero exit code and a message on stderr. For a targeted change to an existing object use `/meta-edit`, for backup and migration use the standard 1C export, and to just inspect the structure use `/meta-info`.

## 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 meta-decompile -a claude-code
```

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

### Codex

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

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

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/meta-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 meta-decompile
```

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

### Gemini CLI

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

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/meta-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/meta-decompile/SKILL.md

## When to use it
- build a DSL draft of a new object from a working example
- rename and adapt the attribute and tabular section set
- get a draft ready for `/meta-compile` without hand-writing the structure
- inspect what structure sits inside an object XML before rebuilding

## Example prompts
- /meta-decompile Catalogs/Sample.xml -OutputPath draft.json
- take this example and build a new catalog from it: change name in draft.json, then compile
- decompile Catalogs/Products.xml and show which attributes land in the draft

# /meta-decompile — DSL-заготовка из XML объекта метаданных

Читает XML объекта метаданных (`Catalogs/Имя.xml` и т.п.) и эмитит компактный JSON в формате `/meta-compile`. Назначение — **взять существующий объект образцом и собрать по нему НОВЫЙ**: декомпилировать → поправить → скомпилировать под другим именем.

## ⚠️ Главное: это НЕ обратимая выгрузка

Компиляция черновика создаёт **новый объект с новой идентичностью**, а не копию исходного. В JSON **не** попадают: UUID (идентичность самого объекта и всех дочерних), тела модулей, формы, макеты, права. Захватываются только структура и свойства.

Отсюда правило: **никогда не компилируй черновик поверх объекта-источника и не выдавай его за «реимпорт»** — у пересобранного объекта другие UUID, поэтому все ссылки на исходный объект (из кода, других объектов, состава подсистем, предопределённых данных) сломаются, а код модулей и формы пропадут.

## Когда использовать

**Собрать новый объект по образцу существующего** — получить DSL-заготовку рабочего объекта, переименовать и адаптировать состав, скомпилировать в новый. Быстрее, чем писать DSL с нуля для богатого объекта.

## Когда **не** использовать
```
