• list_organizations

  List the Flagbearer organizations you belong to. Start here to find an organization's ID. This connection only covers the organizations listed. If the project's application isn't in any of them, tell the user before writing flag code, and ask them to reconnect and approve the ri…

• list_applications

  List the applications in an organization. Flags belong to an application.

• list_flags

  List an application's feature flags with whether each is on, and its rollout percent, in every environment.

• create_flag

  Create a feature flag in an application. It starts off in every environment; use set_flag to turn it on. The key is what code checks, like new-checkout.

• set_flag

  Turn a flag on or off in one environment, by flag key and environment key. When turning a flag on, rolloutPercent says who gets it: 100 for everyone, or a percentage of users. Ask the user whether it should be on for everyone. Without rolloutPercent it's 0, which turns it on onl…

• generate_flag_types

  The text of a TypeScript file listing an application's flag keys, so a misspelled key is a type error and editors autocomplete keys. Write the returned text to the path exactly as it is, and commit it. Only for TypeScript projects using @flagbearer/web (React and browser apps),…

  The current Flagbearer SDK docs for a platform (react, react-native, ios, android, browser, node, python, go, java, dotnet, ruby, rust, cpp or php), plus one environment's SDK address and public client key. Call this before writing code that checks a flag, and follow it.

• check_sdk_setup

  What looks wrong with how an application's SDKs are set up, per environment, from what they sent in the last day: flags the code checks that don't exist, wrong or leaked keys, old SDK versions, and environments nothing has connected to. Call this when flags aren't behaving as ex…
