Best When

An agent needs to check or manage feature flags during deployments, incidents, or automated release workflows using LaunchDarkly.

Avoid When

You're using a different feature flag tool — PostHog, Flagsmith, Unleash, etc.

Use Cases

  • Checking feature flag state during incident investigation by agents
  • Toggling feature flags in response to deployment issues from automation agents
  • Querying experiment results and statistical significance for analysis agents
  • Managing flag targeting rules and rollout percentages via agents
  • Automated flag cleanup after feature graduation or removal

Not For

  • Teams using PostHog, Unleash, or other feature flag providers
  • Real-time feature flag evaluation (use LaunchDarkly SDK for that)
  • Non-LaunchDarkly feature flag systems

Known Gotchas

  • Environment keys are different from project keys — always scope to correct environment
  • Flag toggles are permanent API operations — implement confirmation logic in agents
  • Targeting rules use a specific JSON structure — validate before writing
  • Experiment statistical significance requires sufficient traffic — don't read early results
  • Write rate limit (10 req/s) applies to flag modifications — implement backoff
  • Service tokens preferred over personal API keys for automation
