Installation Guide
How to use bash-defensive-patterns on Cursor
AI-first code editor with Composer
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
- ›Cursor installed and configured on your machine
- ›Node.js 16+ with npm — verify with
node --version - ›Active project directory where you want to add
bash-defensive-patterns
Run the install command
Execute the skills CLI command in your project's root directory to begin installation:
Fetches bash-defensive-patterns from sickn33/antigravity-awesome-skills and configures it for Cursor.
Select Cursor when prompted
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Verify installation
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate bash-defensive-patterns. Access via /bash-defensive-patterns in your agent's command palette.
Security Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Bash Defensive Patterns
Comprehensive guidance for writing production-ready Bash scripts using defensive programming techniques, error handling, and safety best practices to prevent common pitfalls and ensure reliability.
Use this skill when
- Writing production automation scripts
- Building CI/CD pipeline scripts
- Creating system administration utilities
- Developing error-resilient deployment automation
- Writing scripts that must handle edge cases safely
- Building maintainable shell script libraries
- Implementing comprehensive logging and monitoring
- Creating scripts that must work across different platforms
Do not use this skill when
- You need a single ad-hoc shell command, not a script
- The target environment requires strict POSIX sh only
- The task is unrelated to shell scripting or automation
Instructions
- Confirm the target shell, OS, and execution environment.
- Enable strict mode and safe defaults from the start.
- Validate inputs, quote variables, and handle files safely.
- Add logging, error traps, and basic tests.
Safety
- Avoid destructive commands without confirmation or dry-run flags.
- Do not run scripts as root unless strictly required.
