   `prune`/`clean`, the delete guard, and path-safety checks.
 - `src/diff.ts` — `diffTarget`: build to a temp dir and compare against an
   existing target repo (the CI staleness gate).

 ## Targets
 
-`cursor`, `claude`, `antigravity`, `copilot`. Adding a target currently touches ~5
-places: the `TargetName` union (`types.ts`), the `targets` array + `parseTarget`
-(`cli.ts`), `allTargets` (`build.ts`), the `emitters` map + a new `emitFoo`
-(`targets.ts`), and a branch + `validateFoo` (`validate.ts`). If you are adding a
-target, consider introducing a single target registry first to localize this.
+`copilot`, `antigravity`, `cursor`, `claude`, `codex`. Adding a target means one
+new file implementing `PluginTargetDefinition` (`src/targets/<name>.ts`) plus one
+new entry in `src/targets/registry.ts` — `TargetName` (`types.ts`) is still a
+separate union to extend, but everything else (CLI `--target` choices, `build()`'s
+target set, emit/validate dispatch) derives from the registry automatically.
