openfeature-remove-stale-flag

Removes a stale OpenFeature feature-flag evaluation and simplifies leftover control flow once the flag has a permanent value. ## Coverage JS/TS OpenFeature evaluation call sites: | Surface | Matched shapes | | --- | --- | | Node server / web SDK | `*.getBooleanValue('flagKey' \| FlagKeys.X \| constKey, …)` (any receiver; optional `await`) | | React SDK | `useBooleanFlagValue(...)`, `useFlag(...).value` | | Codegen / hand wrappers | `useFlagXxx()` when the resolved function body calls `useFlag(<flagKey>, …)` | ## Params | Param | Type | Default | Description | | --- | --- | --- | --- | | `flagKey` | string | `sample_flag_key` | Literal flag key to remove (also matched via resolved consts) | | `value` | boolean | `true` | Permanent resolved value (`true` = keep the enabled path, `false` = keep the disabled path) | ### Example Dry-run against the current directory (uses defaults: `sample_flag_key` / `true`): ```bash npx codemod run openfeature-remove-stale-flag -t . \ --dry-run \ --report ``` Override for a flag that stayed off: ```bash npx codemod run openfeature-remove-stale-flag -t . \ --param flagKey=sample_flag_key \ --param value=false ``` From a local checkout of this package (before publish), point at the workflow file: ```bash npx codemod workflow run \ -w path/to/openfeature-remove-stale-flag/workflow.yaml \ -t /path/to/your/app \ --dry-run \ --report ``` ## Metric: `openfeature_stale_flag_removed` Emitted once per rewritten evaluation site. | field | description | | --- | --- | | `flag_key` | Matched literal key | | `value` | `"true"` or `"false"` | | `pattern` | Site shape (`await_binding_if`, `inline_await_if`, `ternary`, `logical_and`, `logical_or`, `negated_if`, `with_context`, `simple_replace`, `react_hook`, `generated_hook`, …) | | `outcome` | `rewritten` or `skipped_escaped` | ## Safety - Only flag keys that resolve to the `flagKey` param (literals or one-hop consts / `FlagKeys.X`) - Skips sites where the evaluation result escapes (exports, object properties, callback args) - Does not rewrite bodies of generated `useFlag*` definitions (call sites only) - Idempotent
