PostHog feature flags for .NET applications
— the description by PostHog

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides guidance and best practices for implementing PostHog feature flags within .NET applications. It covers the integration process, architectural considerations for flag management, and strategies for maintaining clean code while using feature toggles. The skill emphasizes server-side evaluation, secure configuration via environment variables, and operational best practices to ensure consistent user experiences and reliable feature deployments.

What it does

  • Provides instructions for integrating PostHog feature flags into .NET projects.
  • Outlines best practices for flag naming, targeting, and lifecycle management.
  • Recommends architectural patterns to minimize code complexity when using flags.
  • Supports management of flags directly via PostHog MCP tools if available.
  • Advises on performance optimization through local evaluation and bootstrapping.

When to use it

  • When you need to perform controlled feature rollouts or A/B testing in a .NET application.
  • When you want to decouple feature deployment from code releases.
  • When you need to manage feature availability based on user properties or groups.
  • When you are looking for standardized patterns to maintain feature flag code in a .NET codebase.

Advantages

  • Enables safer, incremental feature releases.
  • Reduces the risk of deploying broken features to all users simultaneously.
  • Promotes clean code by encouraging centralized flag handling.
  • Improves performance by supporting server-side and local flag evaluation.

Usage examples

“How do I check a boolean feature flag in my .NET application?”
The agent will provide the standard pattern for calling the PostHog SDK to evaluate a boolean flag, ensuring the logic is wrapped appropriately to maintain code readability.
“What are the best practices for naming feature flags?”
The agent will suggest using descriptive, positive-language names that reflect the flag's purpose and return type, such as 'is_premium_user' for booleans.

Documentation by PostHog

PostHog feature flags for .NET

This skill helps you add PostHog feature flags to .NET applications.

Reference files

  • references/dotnet.md - .net feature flags installation - docs

  • references/adding-feature-flag-code.md - Adding feature flag code - docs

  • references/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.

Framework guidelines

No specific framework guidelines.
