/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 project

Creating 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 completeness

Writing 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 providers

Configuring error tracking (

/configure:sentry

instead)

Parameters

$ARGUMENTS

:

--check-only

Report compliance status without modifications

--fix

Apply all fixes automatically without prompting

--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:

OpenFeature JS SDK

Check

npm

OpenFeature Python SDK

Check

PyPI

GO Feature Flag

Check

GitHub releases

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: Indicator Language Detected Provider @openfeature/server-sdk in package.json Node.js OpenFeature (check for provider) @openfeature/web-sdk in package.json Browser JS OpenFeature Web @openfeature/react-sdk in package.json React OpenFeature React openfeature-sdk in pyproject.toml Python OpenFeature Python @openfeature/go-feature-flag-provider Node.js GO Feature Flag go-feature-flag-relay-proxy in docker-compose Any GO Feature Flag Relay flagd in docker-compose/k8s Any flagd provider Step 2: Analyze current state Check for complete feature flag setup: Verify OpenFeature SDK installed for project language Check provider package installed Verify provider initialized in application startup Check evaluation context configuration Check hooks configured (logging, telemetry) For GOFF: verify flag configuration file exists, relay proxy configured 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 . Install OpenFeature SDK and provider packages Create feature flag client wrapper module Create evaluation context helper 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 Create docker-compose entry for relay proxy (local development) 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 Context Command 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 flagscurl -s http://localhost:1031/v1/feature/flags Check SDK installed (JS) `jq -r '.dependencies Flags Flag Description --check-only Report status without offering fixes --fix Apply all fixes automatically without prompting --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
