## Parse Arguments Parse `$ARGUMENTS` to determine the review mode and flags. ### Mode Detection | Priority | Mode | Condition | Description | |----------|------|-----------|-------------| | 1 | **PR Review (explicit)** | `$ARGUMENTS` contains a standalone numeric token (e.g., `42`) or `--pr <number>` | Review a specific PR's diff + commit context | | 2 | **Working Dir (forced)** | `--wd` flag is set | Force working directory review, even on a PR branch | | 3 | **Path Review** | `$ARGUMENTS` contains a file/directory path | Review code at the specified path | | 4 | **PR Review (auto)** | `$ARGUMENTS` is empty → auto-detect (see below) | Auto-detected PR on current branch | | 5 | **Working Dir** | `$ARGUMENTS` is empty and no PR detected | Review current working directory changes (staged + unstaged).
