/configure:feature-flags

Check and configure feature flag infrastructure using the OpenFeature standard with pluggable providers.

When to Use This Skill

Use this skill when...Use another approach when...
Adding feature flag infrastructure to a new projectCreating or editing individual flag definitions in YAML
Setting up OpenFeature SDK with a provider (GOFF, flagd, LaunchDarkly)Debugging why a specific flag evaluation returns unexpected values
Auditing existing feature flag configuration for completenessWriting application logic that consumes feature flags
Configuring relay proxy infrastructure (Docker, Kubernetes)Managing LaunchDarkly or Split dashboard settings
Adding feature flag test helpers and in-memory providersConfiguring error tracking (
/configure:sentry
instead)

Parameters

Parse from 

$ARGUMENTS
:

  • --check-only
    : Report compliance status without modifications
  • --fix
    : Apply all fixes automatically without prompting
  • --provider <provider>
    : Override provider detection (goff, flagd, launchdarkly, split)

Version Checking

CRITICAL: Before configuring feature flags, verify latest SDK and provider versions using WebSearch or WebFetch:

  1. OpenFeature JS SDK: Check npm
  2. OpenFeature Python SDK: Check PyPI
  3. GO Feature Flag: Check GitHub releases
  4. flagd: Check GitHub releases

Execution

Execute this feature flag configuration workflow:

Step 1: Detect project language and existing setup

Check for existing feature flag infrastructure:

IndicatorLanguageDetected Provider
@openfeature/server-sdk
in package.json		Node.jsOpenFeature (check for provider)
@openfeature/web-sdk
in package.json		Browser JSOpenFeature Web
@openfeature/react-sdk
in package.json		ReactOpenFeature React
openfeature-sdk
in pyproject.toml		PythonOpenFeature Python
@openfeature/go-feature-flag-provider
Node.jsGO Feature Flag
go-feature-flag-relay-proxy
in docker-compose		AnyGO Feature Flag Relay
flagd
in docker-compose/k8s		Anyflagd provider

Step 2: Analyze current state

Check for complete feature flag setup:

  1. Verify OpenFeature SDK installed for project language
  2. Check provider package installed
  3. Verify provider initialized in application startup
  4. Check evaluation context configuration
  5. Check hooks configured (logging, telemetry)
  6. For GOFF: verify flag configuration file exists, relay proxy configured
  7. For flagd: verify container/service configured, gRPC/HTTP endpoints

Step 3: Generate compliance report

Print a formatted compliance report:

Feature Flag Compliance Report
==============================
Project: [name]
Language: [detected]
Provider: [detected or None]

OpenFeature SDK:    [status per check]
Provider Config:    [status per check]
Infrastructure:     [status per check]

Overall: [X issues found]
Recommendations: [list specific fixes]

If 

--check-only
, stop here.

Step 4: Install SDK and configure provider (if --fix or user confirms)

Based on detected language, install and configure the OpenFeature SDK with the selected provider. Use code templates from REFERENCE.md.

  1. Install OpenFeature SDK and provider packages
  2. Create feature flag client wrapper module
  3. Create evaluation context helper
  4. Create middleware for HTTP frameworks (Express, FastAPI, etc.)

Step 5: Create flag configuration

Create 

flags.goff.yaml
with example flags covering common patterns:

  • Simple boolean flag
  • Percentage rollout
  • Multi-variant flag (A/B test)
  • Environment-specific flag
  • User-specific override
  • Scheduled rollout

Use flag templates from REFERENCE.md.

Step 6: Configure infrastructure

  1. Create docker-compose entry for relay proxy (local development)
  2. Optionally create Kubernetes manifests for production

Step 7: Create test configuration

Create test file using in-memory provider for feature flag unit tests.

Step 8: Update standards tracking

Update 

.project-standards.yaml
:

components:
  feature_flags: "2025.1"
  feature_flags_sdk: "openfeature"
  feature_flags_provider: "[goff|flagd|launchdarkly]"

Step 9: Print completion report

Print a summary of all changes made including SDK installed, provider configured, flag file created, and next steps (start relay, initialize in app, use flags in code).

For detailed code templates, flag configuration patterns, and infrastructure manifests, see REFERENCE.md.

Agentic Optimizations

ContextCommand
Quick compliance check
/configure:feature-flags --check-only
Auto-fix with GOFF provider
/configure:feature-flags --fix --provider goff
Validate flag config
goff lint --file flags.goff.yaml
Check relay proxy health`curl -s http://localhost:1031/health
List configured flags`curl -s http://localhost:1031/v1/feature/flags
Check SDK installed (JS)`jq -r '.dependencies

Flags

FlagDescription
--check-only
Report status without offering fixes
--fix
Apply all fixes automatically without prompting
--provider <provider>
Override provider detection (goff, flagd, launchdarkly, split)

Examples

# Check compliance and offer fixes
/configure:feature-flags

# Check only, no modifications
/configure:feature-flags --check-only

# Auto-fix with GO Feature Flag provider
/configure:feature-flags --fix --provider goff

# Configure for LaunchDarkly
/configure:feature-flags --fix --provider launchdarkly

Error Handling

  • No package manager found: Cannot install SDK, provide manual steps
  • Provider not supported: List supported providers, suggest alternatives
  • Relay proxy unreachable: Check Docker/K8s configuration
  • Invalid flag syntax: Validate with 
    goff lint
    before deployment
