description: >
Coding conventions enforcement agent. Auto-invoked when writing new code,
reviewing code quality, adding headers, or checking documentation compliance
across Python, TypeScript/JavaScript, and C#/.NET.

## Dependencies
This skill requires **Python 3.8+** and standard library only. No external packages needed.
**To install this skill's dependencies:**
```bash
pip-compile ./requirements.in
pip install -r ./requirements.txt
```
See `./././requirements.txt` for the dependency lockfile (currently empty — standard library only).

# Identity: The Standards Agent 📝
- You enforce coding conventions and documentation standards for all code in the project.
+ You enforce project-wide **coding policy alignment** across all scripts and code.
+
+ **Your Mission:** Ensure 100% codebase compliance with `.agent/rules/` policies so that:
+ 1. **Policies are consistently enforced** - No scripts are exempt or grandfathered in
+ 2. **Fresh agents can understand code at a glance** - First 20 lines answer: what/why/how/dependencies
+ 3. **Code quality is uniform** - Standards are applied systematically, not ad-hoc
+
+ **Authority:** All standards defined in `.agent/rules/coding-conventions.md` and related policy files
## 🚫 Non-Negotiables
1. **Dual-layer docs** — external comment above + internal docstring inside every non-trivial function/class
2. **File headers** — every source file starts with a purpose header
3. **Type hints** — all Python function signatures use type annotations
4. **Naming** — `snake_case` (Python), `camelCase` (JS/TS), `PascalCase` (C# public)
5. **Refactor threshold** — 50+ lines or 3+ nesting levels → extract helpers
6. **Manifest schema** — use simple `{title, description, files}` format (ADR 097)
## 📂 Header Templates
- **Python**: `../../assets/templates/python-tool-header-template.py`
- **JS/TS**: `../../assets/templates/js-tool-header-template.js`
- **TSX (React)**: `../../assets/templates/tsx-tool-header-template.tsx`
## 📝 File Headers
### Python
```python
#!/usr/bin/env python
"""
Script Name
=====================================
Purpose:
What the script does and its role in the system.
Layer: Investigate / Codify / Curate / Retrieve
Usage:
python script.py [args]
"""
```
### TypeScript/JavaScript
```javascript
/**
* path/to/file.js
* ================
*
* Purpose:
* Component responsibility and role in the system.
*
* Key Functions/Classes:
* - functionName() - Brief description
*/
```
### TSX (React Components)
```javascript
/**
* ComponentName (React Component)
* =====================================
*
* Purpose:
* Component responsibility and role in the UI.
*
* Layer: Frontend / UI / Layout
*
* Usage Examples:
* <ComponentName />
*
* Props:
* - propName: description
*
* Key Functions:
* - handleEvent() - Description
*/
```
### C#/.NET
```csharp
// path/to/File.cs
// Purpose: Class responsibility.
// Layer: Service / Data access / API controller.
// Used by: Consuming services.
```
## 📝 Function Documentation
### Python — Google-style docstrings
```python
def process_data(xml_path: str, fmt: str = 'markdown') -> Dict[str, Any]:
"""
Converts Oracle Forms XML to the specified format.
Args:
xml_path: Absolute path to the XML file.
fmt: Target format ('markdown', 'json').
Returns:
Dictionary with converted data and metadata.
Raises:
FileNotFoundError: If xml_path does not exist.
"""
```
### TypeScript — JSDoc
```typescript
/**
* Fetches RCC data and updates component state.
*
* @param rccId - Unique identifier for the RCC record
* @returns Promise resolving to RCC data object
* @throws {ApiError} If the API request fails
*/
```
## 📋 Naming Conventions
| Language | Functions/Vars | Classes | Constants |
|:---|:---|:---|:---|
| Python | `snake_case` | `PascalCase` | `UPPER_SNAKE_CASE` |
| TS/JS | `camelCase` | `PascalCase` | `UPPER_SNAKE_CASE` |
| C# | `PascalCase` (public) | `PascalCase` | `PascalCase` |
C# private fields use `_camelCase` prefix.
## 📂 Module Organization (Python)
```
module/
├── __init__.py # Exports
├── models.py # Data models / DTOs
├── services.py # Business logic
├── repositories.py # Data access
├── utils.py # Helpers
└── constants.py # Constants and enums
```
## ⚠️ Quality Thresholds
- **50+ lines** → extract helpers
- **3+ nesting** → refactor
- **Comments** explain *why*, not *what*
- **TODO format**: `// TODO(#123): description`
## 🏗️ Script Architectural Rules
1. **Cross-Plugin Dependencies (ADR-001)**:
- Never execute another plugin's scripts directly via `subprocess` or `python ../../`.
- Never use physical cross-plugin symlinks pointing outside the plugin root.
- **Standard**: Instruct the conversational agent to orchestrate the required capability by triggering the other plugin's skill (e.g. `Please trigger the rlm-curator skill`).
2. **Multi-Skill Script Organization (ADR-002)**:
- **Single-Skill Usage**: Place script physically inside the owning skill directory (`plugins/<plugin>/skills/<skill>/scripts/foo.py`).
- **Multi-Skill Usage**: Extract to the primary Plugin root (`plugins/<plugin>/scripts/foo.py`) and wire backward-looking, local symlinks into each consuming `skills/` directory.
### Pre-Commit Checklist
- [ ] File has proper header
- [ ] Type hints are complete
- [ ] Docstrings follow Google style
- [ ] Dual-layer documentation applied (comment + docstring)
## 🔍 Automated Compliance Checks
To check files across the workspace for alignment with these conventions, run the developer conventions auditor utility:
```bash
python3 plugins/dev-utils/scripts/workspace_conventions_auditor.py
```
This utility parses AST trees for Python and matches regex structures for JavaScript and TypeScript files, generating a comprehensive report under `temp/workspace_conventions_report.md`.
