name	create-feature-toggle
description	Add a new feature toggle backed by Firebase Remote Config. Use when the user asks to create a new feature toggle.

Required Input

Ask the user for:

1. Feature name - descriptive name (e.g. "surface view map", "ticket information")
2. Default value - true or false

The remote config key will be derived as enable_<snake_case_name> and the toggle spec name as is<PascalCaseName>Enabled.

Steps

1. Add to Remote Config type (src/modules/remote-config/remote-config.ts)

Add the new key to the RemoteConfig type (keep alphabetical order among enable_* keys):

enable_<name>: boolean;

2. Set the default value (src/modules/remote-config/remote-config.ts)

Add to defaultRemoteConfig (keep alphabetical order):

enable_<name>: <default_value>,

3. Read from Firebase (src/modules/remote-config/remote-config.ts)

In the getConfig() function, add a variable that reads the value with fallback to default (keep alphabetical order among similar declarations):

const enable_<name> =
  values['enable_<name>']?.asBoolean() ??
  defaultRemoteConfig.enable_<name>;

Then add enable_<name> to the returned object in getConfig() (keep alphabetical order).

4. Add toggle specification (src/modules/feature-toggles/toggle-specifications.ts)

Add a new entry to the toggleSpecifications array (keep alphabetical order):

{
  name: 'is<PascalCaseName>Enabled',
  remoteConfigKey: 'enable_<name>',
},

5. Verify

Run yarn tsc to check for type errors, then run yarn prettier --write on changed files followed by yarn prettier to verify formatting.
