### PostHog Java Feature Flags
- ›Install the PostHog Java library and integrate flag checks directly into existing application logic using the provided documentation.
- ›Securely manage PostHog API keys using environment variables and prioritize server-side evaluation to prevent UI flickering.
- ›Utilize available PostHog MCP tools to programmatically create, list, and update feature flags directly from your development environment.

PostHog feature flags for Java
This skill helps you add PostHog feature flags to Java applications.
Reference files
references/java.md- Java feature flags installation - docsreferences/adding-feature-flag-code.md- Adding feature flag code - docsreferences/best-practices.md- Feature flag best practices - docs
Consult the documentation for API details and framework-specific patterns.
Key principles
- Environment variables: Always use environment variables for PostHog keys. Never hardcode them.
- Minimal changes: Add feature flag code alongside existing logic. Don't replace or restructure existing code.
- Boolean flags first: Default to boolean flag checks unless the user specifically asks for multivariate flags.
- Server-side when possible: Prefer server-side flag evaluation to avoid UI flicker.
PostHog MCP tools
Check if a PostHog MCP server is connected. If available, look for tools related to feature flag management (creating, listing, updating, deleting flags). Use these tools to manage flags directly in PostHog rather than requiring the user to do it manually in the dashboard.

How to use feature-flags-java 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 development machine
- ›Node.js version 16.0+ with npm package manager (verify with
node --version) - ›Active project directory or workspace where you want to add feature-flags-java
Execute installation command
Execute the skills CLI command in your project's root directory to begin installation:
The skills CLI fetches feature-flags-java from GitHub repository PostHog/skills and configures it for Cursor.
Select Cursor when prompted
The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:
Verify installation
Confirm successful installation by checking the skill directory location:
Reload or restart Cursor to activate feature-flags-java. Access the skill through slash commands (e.g., /feature-flags-java) or your agent's skill management interface.
Security & Verification 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 development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.

Implementation Guide▌
Prerequisites
- ›Claude Desktop or compatible AI client with skill support
- ›Clear understanding of task or problem to solve
- ›Willingness to iterate and refine outputs
Time Estimate
15-45 minutes depending on use case complexity
Installation Steps
- 1.Install skill using provided installation command
- 2.Test with simple use case relevant to your work
- 3.Evaluate output quality and relevance
- 4.Iterate on prompts to improve results
- 5.Integrate into regular workflow if valuable
Common Pitfalls
- ⚠Expecting perfect results without iteration
- ⚠Not providing enough context in prompts
- ⚠Using skill for tasks outside its intended scope
- ⚠Accepting outputs without review and validation
Best Practices▌
✓ Do
- +Start with clear, specific prompts
- +Provide relevant context and constraints
- +Review and refine all outputs before using
- +Iterate to improve output quality
- +Document successful prompt patterns
✗ Don't
- −Don't use without understanding skill limitations
- −Don't skip validation of outputs
- −Don't share sensitive information in prompts
- −Don't expect skill to replace human judgment
💡 Pro Tips
- ★Be specific about desired format and style
- ★Ask for multiple options to choose from
- ★Request explanations to understand reasoning
- ★Combine AI efficiency with human expertise
When to Use This▌
✓ Use When
Use when skill capabilities match your task, clear ROI on time saved, and you can validate outputs. Best for repetitive tasks, learning, and quality improvement.
✗ Avoid When
Avoid when task requires deep expertise you can't validate, involves sensitive decisions, or when learning process is more valuable than speed of completion.
Learning Path▌
- 1Familiarize yourself with skill capabilities and limitations
- 2Start with low-risk, non-critical tasks
- 3Progress to more complex and valuable use cases
- 4Build expertise through regular use and experimentation
