+# Change request: Reduce redundant GetRootFolder calls in hook.go
+
+## Why
+
+`GetRootFolder()` spawns a `git rev-parse --show-toplevel` subprocess each time it is called. In `gitcmds/hook.go` it is called 5 times, but several calls are redundant within the same call chain — the result is already available from a caller up the stack.
+
+## What
+
+Eliminate redundant `GetRootFolder()` calls in `gitcmds/hook.go` by passing the already-resolved root dir down the call chain:
+
+- `fillPreCommitFile`: accept `rootDir` parameter instead of calling `GetRootFolder` (caller `SetLocalPreCommitHook` and `SetGlobalPreCommitHook` already have it or can obtain it once)
+- `isLargeFileHookContentUpToDate` and `updateLargeFileHookContent`: accept `rootDir` parameter instead of calling `GetRootFolder`; `EnsureLargeFileHookUpToDate` calls `GetRootFolder` once and passes it to both
+- `getLocalHookFolder`: accept `rootDir` parameter instead of calling `GetRootFolder` (caller `LocalPreCommitHookExist` obtains it)
+- Net result: 5 calls reduced to 3 (one each in `SetLocalPreCommitHook`, `EnsureLargeFileHookUpToDate`, `LocalPreCommitHookExist`)

+## Construction

+- [x] update: [gitcmds/hook.go](../../../../../gitcmds/hook.go)
+  - refactor: `fillPreCommitFile` — replace `wd` param with `rootDir`, remove internal `GetRootFolder` call
+  - refactor: `isLargeFileHookContentUpToDate` — replace `wd` param with `rootDir`, remove internal `GetRootFolder` call
+  - refactor: `updateLargeFileHookContent` — replace `wd` param with `rootDir`, remove internal `GetRootFolder` call
+  - refactor: `getLocalHookFolder` — replace `wd` param with `rootDir`, remove internal `GetRootFolder` call
+  - refactor: `EnsureLargeFileHookUpToDate` — call `GetRootFolder` once, pass result to `isLargeFileHookContentUpToDate` and `updateLargeFileHookContent`
+  - refactor: `SetLocalPreCommitHook` — pass existing `dir` to `fillPreCommitFile`
+  - refactor: `SetGlobalPreCommitHook` — call `GetRootFolder` once, pass result to `fillPreCommitFile`
+  - refactor: `LocalPreCommitHookExist` — call `GetRootFolder` once, pass result to `getLocalHookFolder`
