File Reference Skill

This skill demonstrates how to use supporting files (scripts, templates, documentation) within a skill directory.

Overview

This skill uses helper scripts and templates for data processing. All supporting files are accessible via relative paths from the skill's base directory.

Available Supporting Files

Scripts

```
scripts/data_processor.py
```
- Main data processing script
```
scripts/validator.py
```
- Input validation utilities
```
scripts/helper.sh
```
- Shell helper script

Templates

```
templates/config.yaml
```
- Configuration template
```
templates/report.md
```
- Report generation template

Documentation

```
docs/usage.md
```
- Detailed usage instructions
```
docs/examples.md
```
- Example use cases

Usage

When this skill is invoked with arguments, it can access supporting files using the FilePathResolver:

from pathlib import Path
from skillkit.core.path_resolver import FilePathResolver

# Get the skill's base directory (injected by BaseDirectoryProcessor)
base_dir = Path("<base_directory_from_context>")

# Resolve supporting files securely
processor_script = FilePathResolver.resolve_path(base_dir, "scripts/data_processor.py")
config_template = FilePathResolver.resolve_path(base_dir, "templates/config.yaml")
usage_docs = FilePathResolver.resolve_path(base_dir, "docs/usage.md")

# Read file contents
with open(processor_script) as f:
    script_code = f.read()

Processing Arguments

The skill expects data file paths as arguments:

Example invocation:

file-reference-skill data/input.csv data/output.csv

Processing steps:

Validate input using
```
scripts/validator.py
```
Process data using
```
scripts/data_processor.py
```
Generate report using
```
templates/report.md
```
Output results to specified location

Security Notes

All file paths are validated to prevent directory traversal attacks
Symlinks are resolved and verified to stay within skill directory
Absolute paths and path traversal patterns (../) are blocked
Any security violation raises PathSecurityError with detailed logging
