Perplexity

Terminal-based Flagsmith control

Claude Code uses `update_flag_v2` to batch update flags directly from your shell. It fits into your existing CI/CD pipelines without requiring a GUI. You trigger the change as part of a deployment script. It returns the status immediately, allowing you to gate your production releases programmatically.

Fetch environment data in Claude Code

The `get_environment_document` tool provides the full config in your terminal output. You pipe this data into other tools or log files for auditing. It helps you verify environment consistency across different stages. You get the raw data needed to confirm that your production flags are correctly set.

Manage identities with Claude Code

Claude Code calls `identify_user` to set traits during automated runs. This ensures your integration tests use the right user context every time. You can chain this with `get_identity_flags` to verify responses. It makes headless testing of personalized features reliable and fast.
